The picture on the cover of the magazine shows a sculpture on a moun-tain between Meran and Bozen in Italy, sometimes called Rubbish Hill where large amounts of rubbish are buried. The sculpture is intended to encourage people in the region to consider unlocking the rubbish and clean it up for ecological reasons.

Sculpturer Stefan Spren-ker needs the rights tools to transfer stone into the desired image. In this case he used a hydraulic powered chain saw from ICS. “As a sculptor growing with each challenge and the stones used for raw material, my inner request is to create similar sculptures, but in a larger dimension,” says Sprenker. “But a freelance sculptor has limited funds, so it makes sense to finance in advance such a large project. I am looking for sponsors or people interesting in buying projects. The right stone is still selected and comes from Sweden.”

16-18 The PDi Concrete Cutting Survey 2009

Dear Readers

Here we are again, the end of another year, or perhaps at the beginning of a new year

as when you receive this issue we will already be in 2010. I am quite happy that 2009

is over, as it was most dreadful for many of us. The market literally collapsed at the

end of 2008 and that has continued during 2009, despite a small upturn at the end

of the year. This is a positive move that might give us a hint that the market might

grow slightly during 2010 and continue in 2011.

It feels quite good to make a fresh start in 2010. As a magazine and as one of

the market organs that can assess the market we feel optimistic. Proof of that is an

increase is sales of advertising. Another is the number of new products launched has

also increased.

This issue of PDi carries our annual concrete cutting survey and I am pleased

to write that manufacturers of concrete sawing and drilling equipment, as well as

diamond tools, have quite a lot of new products in the pipeline. Some of them are

already available and some will be launched at the World of Concrete and Bauma

shows. Previews of these shows are also included in this issue of PDi.

This year will also be quite interesting as Tyrolit is again organising their well

received Cutting Pro Competition, which will start with a number of national com-

petitions during 2010 to end up with the Grand Final in 2011 where the world’s best

concrete cutter will be decided. PDi Magazine will as usual be a sponsor of the event

and each national championship will be covered in the magazine.

2010 is also a special year as PDi is part of the organisation of a new exhibition

called DEMCON, which will take place in Stockholm 9-10 September. This show is

dedicated to the international concrete cutting, demolition and recycling industries

and has already received considerable interest from exhibitors. More information on

Demcon can be found at www.demcon.se. I am also pleased to announce that the

International Association of Concrete Drillers & Sawers will hold their annual meeting

on 23 April in conjunction with Bauma in Münich. IACDS will organise a series of

seminars under the title of ‘The Very Best of Diamond Technology’. A number of

well-known speakers will share their thoughts of the future of concrete sawing and

drilling technology. There is further information about the seminars www.iads.org.

Sadly I also have to inform that one of Russia’s big names in concrete sawing and

drilling Yury Mokin passed away just before Christmas. Yury was only 42 and had been

the driving force for 16 years behind the concrete sawing and drilling and demolition

contractor Olvex, which he founded and owned with a colleague and friend.

Olvex, based in St Petersburg, is one of the biggest European contractors in

its field. I had the privilege to meet Yury Mokin on several occasions and pleased I

had the opportunity to know him, but sad that this industry has lost such a young

and inspirational force. I would like to express PDi’s condolences to Yury Mokin’s

family, friends and colleagues at Olvex at

this difficult time. An obituary by Yury’s

colleague at Olvex, Andrei Bushmarin,

appears on page 54 in this issue.

Finally I would like to wish all our

readers the very best in 2010.

President IACDS

IACDS Invites to “The Very Best of Diamond Technology” at BaumaI have been a member of the American CDSA for some 27 years, which gave me the idea of starting the British Drilling & Sawing Association the following year and I am also a founder member of the ISCDS-IVBS, the World Association.

The benefits that I personally and my Company in general have obtained from the Association are tremendous. I can draw upon the experience of members worldwide when it comes to information on complicated jobs, Health & Safety, training, safety manuals, marketing and access to web sites, insurance issues, industrial research, specifications and best practices and even accounting information, for good or bad of a drilling and contracting company. But the biggest benefit, I found, was that the problems that went on in my own company do happen world wide and you are not alone. Then talking to other member companies about these problems helped me and my company find the solutions.

With all my years of working and join-ing in the associations, my view is that it should be of a benefit and interest of all drilling, demolition or any other type of company to join their trade association, whether large or small the benefits are numerous. Small companies would ben-efit from what the larger companies have implemented and help networking and hopefully help harmony in the trade.

When I visit all the annual conference through out the world, I always find very useful ideas being passed around the conference table I then come back to England with two or three new ideas which we can then proceed to put into practice in my own trade association and my company. So in all I can highly recommend any company in the cutting profession, demolition or any other trade to join there trade association. One more fantastic benefit I have gained is that I have person-ally made some very good friends from the asso-ciations worldwide and hol idayed with them throughout Europe and World.

Words from O’Brien

MembershipValue in Chal-lenging TimesIn previous columns, I have talked about

increasing market share in a down economy

and expanding business offerings to include

services such as selective demolition,

ground penetrating radar imaging, concrete

flatwork and concrete removal to better

serve the customer base. But membership in

a sawing and drilling association often offers

resources that can help a company succeed

in business during tough economic times.

In member surveys conducted over

the past 20 years, the number one benefit

of CSDA membership has always been

networking. The community of sawing and

drilling professionals is always willing to

assist another member with information,

equipment, personnel and more. This is a

testament to the quality of the fine people

who make up this industry and their dedica-

tion to it. Members who are able to attend

the annual conventions or seasonal meet-

ings meet face-to-face with their peers from

around the country, even around the globe,

to exchange information and best practices

to help them succeed in business. For those

members not able to travel, assistance

is available via phone or Internet. CSDA

often facilitates conversations between

members and it is not uncommon that

this reach extends to the far corners of the

globe with 20% of the membership located

outside the US.

CSDA also provides a variety of other

support services, most of which are avail-

able to members 24/7 via the Internet. Some

of the most frequent requests are for silica,

slurry and safety information. Members

are also being asked to justify what type

of protective masks, if required, should be

provided for their operators. Most contrac-

tors simply do not have the time or funds

to develop a comprehensive data base to

respond to a request like this. CSDA has

assembled a data base of over 100 separate

items identifying different types of sawing

or drilling operations and for each a NIOSH

(National Institute for Occupational Safety

and Health) recommended protection is

provided, whether it is a N100 disposable

filter, 1/2-face respirator or no protection

required. Each of these data points was

developed from NIOSH or individual contrac-

tor testing and it would be difficult for any

one company to compile such an exhaustive

data base.

How to handle the disposal of slurry

is another area that contractors have to

justify to their customer. Many want to

consider slurry as a hazardous material and

dispose of it in accordance with established

practices, which are expensive. CSDA hired

an environmental engineering firm to test

different slurry samples from a wide geo-

graphic area and the results show that slurry

is not a hazardous material. Contractors can

use this 62-page report to justify how slurry

is to be disposed of thus saving the time and

expense of hazardous disposal.

The CSDA Safety Manual is yet an-

other aid for contractors who don’t have

the resources to develop their own company

safety program targeted for the sawing and

drilling industry. This 230-page manual is

available in an electronic file and can be

easily customized with the company name

to provide a personalized safety program

for your company.

These are just a few of the resources

and services offered by an association like

CSDA. They have been developed in re-

sponse to the wants and needs as expressed

by contractors over time. Hopefully they will

be useful to make running a contracting

business a bit easier during tough economic

times while increasing the chances to thrive

in business.

Date and venue for 2010 Demolition Awards announcedThe 2010 World Demolition Awards will be presented on 5 November 2010, once again at the Hotel Okura in Amsterdam. The closing date for entries will be Friday 30 July. Entries for the various categories should cover work carried out or completed during 2009. No entries will be accepted after this date. The Demolition Awards will form part of the 2010 World Demolition Summit - a gathering of many of the major players in the global demolition industry, as well as leading equipment suppliers to the industry.

DA rejoins EDAFollowing a board meeting on 1st December, the Deutsch Abbruchverband (German Demolition Association) has voted to rejoin the European Demolition Association (EDA) with effect from 2010. According to DA president Walter Werner, this deci-sion was backed by a large majority of the board members present at the meeting. This is good news for the EDA, since it brings back to the fold one of the larger and more active of the national European demolition associations.

Smart dust suppres-sion solution between Hinowa and WLPHinowa has introduced a crawler mounted dust

suppression system, which is a combination of their tracked Goldlift 14.70 and a WPL410 rotating dust suppression gun. The Goldlift 14.70 is able to elevate the nozzle to a maximum height of 12 m (39.4 ft) to maximise the throw area. The WLP410 itself has a maximum throw distance of 30 m (98.5 ft), offers 320º rotation and can cover up to 2,800 m2 (30,100 square feet). Recommended operat-ing pressure is 10 Bar, at which pressure it uses 35 litres (7.7 gallons) of water per minute. Hinowa has also made this unit available on its TP1800 tracked forklift.

Lodab and Segerström join forcesTwo of Sweden’s largest demolition contractors, Lodab Demolering AB and Entreprenad AB Sven Segerström, have joined forces. The new company is called Demolition Company AB but is shorted DemCom AB. The aim is to maintain the leading position in terms of demolition, recycling, industrial clearance and decontamination. Initially the new company will employ 80 and is expected to reach an annual turn over of some EUR 19M. DemCom will have offices in Stockholm, Örebro and Fagersta. President for the company will be Stefan Petersson and Vice President Johan Segerström. The new company will be owned 100% by the families Dahl (Lodab Demolering AB) and Segerström (Entrepre-nad AB Sven Segerström).

A perfect co-operation“We are very enthusiastic about the strong industrial power in this merger which will create a very strong Northern Europe based demolition and recycling player,” says Lars-Olov Dahl founder of Lodab. Both Lodab and Segerström have a long tradition and great knowledge from the fields they have been working in. The two founding companies are also very profitable, have well protected market shares and clear visions about how they would like to work and grow. DemCom will be a continuation of these visions and a concentration of forces as well as expansion in to new business ideas. One to mention is to the develop the company sectors waste handling and recycling.

DemCom will survey first of all the entire Nordic market and in order to capture more market shares new local offices will be opened in northern Europe.

“DemCom will have a size and a financial solidity which will guarantee substance, trust and security to large international clients. Both founding companies of DemCom have since the start had a clear focus on optimal training, methods and right choice of equipment, which has lead to a continuous growth and preserved profitability in both companies. This means that DemCom will be well equipped for profitable growth and international expansion which will benefit our clients, our employees, partners and the company itself,” says DemCom President Stefan Petersson.

Brokk acquires its Australian distributor The Swedish manufacturer of remotely controlled demolition machines, Brokk AB, has acquired the Australian company Kiwi Operations Downunder Pty Ltd. The companies have worked together for several years, Kiwi Operations Downunder being Brokk’s distributor in Australia. This will be the sixth subsidiary after the most recent in Singapore where Brokk inaugurated its Asia-Pacific Regional Head Office earlier in 2009.

The acquisition will allow Brokk to better support its customers in Australia and New Zealand and make long-term investments for a stronger presence in Australia. The operations will continue in the same premises in Adelaide, centrally located in Australia. The current staff of Kiwi Operations Downunder Pty. Ltd. will be transferred to the new subsidiary Brokk Australia Pty. Ltd.

“Strategically this is an important step towards a stronger presence in the Asia-Pacific region, which has become a very important market for Brokk. Setting up our own subsidiary will show our customers a strong commitment to the Australian market to ensure them

New option for Bobcat loaders A new factory-installed road option is now available for all Bobcat loader models produced at the Bobcat compact equipment plant in the Czech Republic.

The new road option, which equips the loaders for travel and use on roads throughout the European Union, can be fitted to the S100, S130, S150, S160, S175 and S185 skid-steer loaders as well as the new T110 compact tracked loader, all of which are produced at the Bobcat factory in Dobris.

Chicago Pneumatic’s new breaker oilChicago Pneumatic has introduced its fully synthetic Airolene Plus Tool Oil with anti-frost properties. The biodegradable lubricant has been developed for pneumatic paving breakers, chipping hammers and rivet busters.

Continuous lubrication is needed even more in frosty weather conditions. Pneumatic breakers and hammers might experience downtime from freezing caused by ice formations in and around ports and valves. This is what Chicago Pneumatic Airolene Plus Tool Oil avoids with its ice-dissolving power.

The lubricant has been especially designed for demanding applications. All pneumatic tools face risk of corrosion. Airolene Plus Tool Oil permanently absorbs moisture and protects pneumatic tools against corrosion. It supports smooth, continuous op-eration even under extreme conditions. Continuous lubrication optimises machine lifetime and reduces maintenance costs.

Airolene Plus Tool Oil is readily biodegradable accord-ing to OECD 301. This defines a product with biodegradability over 60% within 10 days.

In addition Chicago Pneu-matic has also developed the similar semi-synthetic Airolene Plus Rock Drill Oil for pneumatic rock drills. It is insensitive to ambient temperature and helps to protect against wear and corrosion.

The Cathedral in “Den Bosch”It took almost 10 years to restore the magnificent Cathedral in gothic style located in the Dutch city of Den Bosch. The renovation is now in the last phase and the old Cathedral has been cut up into 6000 pieces. These have been carefully renovated and replaced. The Dutch renovation compa-ny Nico de Bont B.V. has used hydraulic chain saws and diamond chains from the US manufacturer ICS Blount to carry out the complicated and time consuming restoration. PDi’s Mikael Karlsson reports.

To restore old historical buildings and churches every effort is made to conserve the old structures as much as possible. It can take decades to complete a major restoration, which needs to be done in a cost effective way with a fixed budget.

Occupied 45 expertsThe supervisor of the Dutch renovation company Nico de Bont B.V., Toon Weyters is well aware of how it works. He and his workforce of 25 have been restoring the huge St. Jan Cathedral in Den Bosch in southern Netherlands for almost ten years. Along with them, about 20 history and church experts have been recruited to ensure the restoration is performed in every detail, such as repairing sculptures, ornaments and artwork.

Construction of the huge Cathedral started in the 13th century and lasted throughout the late Middle Ages. St. Jan is a testimony of the typical gothic style of the Dutch Brabant region and an architectural masterpiece and important tourist attraction. At Christmas in 2010 the long restoration should be completed at a cost of EUR43.2M, with the money coming from voluntary collections and taxes. The whole restoration process has been divided into 11 different phases. And the last one is to take off the sandstone, limestone and Portland stone of different ages and quality and repair it.

6,000 piecesThe job is performed piece-by-piece and block-by-block. “We actually cut down the stone structure of the church in 6,000

pieces according to very detailed drawings prepared using an American computer scanning method. The computer program analyzes the structure and material in every detail and divides the church into a puzzle to be cut piece by piece. Every piece and block is organized in order and by number in order to

know exactly how to rebuild the church again. However, the actual stone cutting has to be done manually with hydraulic concrete chain saws. There is no other way to do it and is a hell of a job,” says Toon Weyters.

ICS - Modern techniques and good toolsTwo stone cutters are constantly working between three to five hours a day cutting out the blocks and pieces, the biggest block measuring 2m3 and then they degrade down to small fragments. They use ICS hydraulic concrete chain saws, including the 880F4 model and some older types such as 853 Pro. They are all equipped with the new type Abrasive Pro Force 4 diamond chains of 380mm. Due to the large amount of tough hardcore cutting two machines are working constantly, while two are on maintenance and one spare machine in case of breakdown. “We actually delivered the first ICS saws in 2000 and have constantly been involved to supply new saws as well as spare parts and service as quick as possible to Nico de Bont,” says René van der Wegen of Van Voorden B.V., the distributor of ICS equipment in the Netherlands. “This is a huge and tough job and we must guarantee full availability of the ICS saws, no margins for unexpected breakdowns.”

Nico de Bont has been using ICS hydraulic chain saws since the very start of the church renovation. Modern techniques and good tools, together with personal involvement of trained employees with concern for the monument, craftsmanship and attention to details guarantee that the job is done correctly and on time.

The actual stone cutting has to be done manually with hydraulic chain saws. “There is no other way to do it and is a hell of a job,” according to Toon Weyters.

Some 25 employees of Nico de Bont and 20 externally recruited church and art experts are restoring the Cathe-dral, piece by piece.

The St. Jan Cathedral is a testimony of the typical gothic style of the Dutch Brabant region, a real architectural masterpiece and an important tourist attraction in the city of Den Bosch.

All renovated pieces are carefully put back in place.

This is where all pieces were kept during the renovation.

The 2010 generation of Atlas Copco Cobra™ pet-rol drill and breakers meet the stricter requirements of exhaust emission set by the US based Environ-mental Protection Agency. Phase 2 of the Exhaust emission standards for small non-road engines of the EPA and its EU equivalent, EG 97/68/EG with amendment 2002/88/EG constitute a reduction of hydrocarbon and nitrogen oxide emissions and are probably the most demanding in the history of en-vironmental regulations. Compared to the previous generation of Cobra™ machines, the emission of hydrocarbons has been reduced by approximately 50%. Featuring improved carburettor and filter systems and redesigned and fine tuned noise reduction system, including a catalytic element, the new generation of Cobra™ petrol drill and break-

Clean air from Italy

The Italian company WLP S.r.l. in Trento that manu-facturers dust suppression guns has strengthend its position on the global market during the last years. WLP provides a comprehensive technology for dust suppression and odour control for a wide range of industries. Fields of applications include building and demolition sites, recesses and inert recycling systems, cement factories and concrete production plants, construction of roads and tunnels, steel factories and compost production plants, wood processing plants, solid urban waste landfill sites and transfer, mining and quarrying,

environmental remediation and ports and shipping sites. The WLP dust suppression and odour control system can reduce the cost of dust control by around 50%, according to WLP. Most companies realize payback in six months or less.

Dust and odour control systemsWLP’s dust suppression and odour control system reduces the problem of dust and odour in all sites (inside or outside). Each WLP system tries to reproduce a natural phenomenon artificially. The machine has several nozzles that eject tiny drops

of water. These drops capture the dust particles in the air and make them sink to the ground. Besides the guns, a complete system includes a pumping station, a water distribution system, an electrical power distribution system, a data transmission system and a programming, control and monitoring unit.

Dust suppression system advantages

WLP’s dust suppression system is, according to the manufacturer, more efficient than traditional systems because of the following:

• WLP dust suppression systems use less water than traditional water sprinklers with a fine mist of water droplets ranging in size from 50µm-200µm, the best size for dust suppression• WLP’s dust suppression gun covers a large area between 9,200ft2 and 39,400ft2

• Less mud means construction sites and machines stay cleaner, therefore reducing the need for clean-up• No need for employing people to wet roads and squares (not having to employ people means a significant return on investment)• Machines are easy to use and install, and after set-up, can be run 24/7• The use of a system that protects the environment always makes a good impression on public authorities and environmental organizations• WLP dust suppression systems make the work place healthier and cooler during the summer

Low-energy dust suppression gun

The WLP dust suppression gun helps to improve ambient air quality, protect the local environment and reduce neighbour complaints. WLP units use a high-pressure system to create an ultra-fine mist, attracting dust and odour particles and driving them to the ground to ensure the best dust and odour suppression.

Depending on the model, the WLP gun can blanket between 854 m2 (9,200ft2) and 3,660 m2 (39,400ft2) and provides the lowest energy consumption per square foot. WLP aims to provide energy savings, with its machines designed to use minimal power. WLP models are available in either mobile or standing units, to provide you with the best solution for your site.

ers meets the requirement for exhaust emissions demanded by the stricter emission limits.

The new Cobra™ petrol breakers are easy to start. All models feature an electronic ignition, choke and a re-designed tank cap. Cobra™ Pro and TT additionally contain a decompression valve. An optional guide roller is available for Cobra™ Combi to make it easy to pull downwards to start the machine when it is positioned high in relation to the operator. Long life and easy service is achieved through a high capacity air filter, which is easy to access for fast servicing.

All Cobra™ machines work independently from external power sources. Transfer to and off site is easy and can be carried out by a single operator. Cobra ™ Combi is a multi-purpose

machine featuring high impact mechanism with rotation option and a built in compressor, ideal for onsite jobs such as breaking, drilling, cutting, driving and compacting.

Cobra™ Pro is the combination of high per-cussive energy and high blow frequency. It delivers almost twice the impact energy of other petrol-driven breakers and offers the same power-to-weight ratio as many pneumatic or hydraulic breakers. Cobra™ Pro is used for breaking concrete and asphalt, dig-ging, driving posts and fences, rods and spikes and for tamping and compacting.

Cobra™ TT has been specially designed for tie tamping. It works at the relatively high frequency of 1,620 blows/min and the impact energy has been optimized to prevent pulverization of ballast.

special surveyspecial survey

The global economi-cal crisis has hardly spared any nation and undoubtedly it has affected the interna-tional diamond tool and concrete sawing and drilling industry. PDi’s annual Concrete Cutting Survey used to receive help with sta-tistics from the Inter-national Association of Concrete Drillers and Sawers. But IACDS has not presented any data for 2008 and the 2009 figures are also not yet available. This Concrete Cutting Survey is, therefore, based on data PDi has collected during 2009.

In 2008 the effects of the crisis were more diversified. Some nations had hardly suffered while others were about to enter the recession. In 2009 most countries experienced the crisis with cut backs in market value ranging between 25 to 55%. The figures mainly represent the situation in Europe, USA and Japan. The biggest drop in market value came during 2008 and 2009 has, in most areas, represented stagnation with a slight recovery in turnover during the second part of the year. Some countries in Europe have had the strongest cut backs in 2009, but it seems like the market is recovering faster then expected. Germany is an example of this as the German Sawing & Drilling Association has reported that it has strengthened its number of members from 479 in June 2008 to 532 in June 2009. The number of manufacturing members has also increased from 37 to 41 in the same period.

The near future

But what about 2010 and 2011? PDi has spoken to rep-resentatives from several associations and manufacturers and most of them are largely in agreement that we have seen the bottom of the crisis, in Europe and USA. The Russian market and some of the other eastern European nations may have a little more to go before there is a change for the better. The same probably applies to the Japanese market. Asia Pacific, and in particular Australia, might not have yet fully experienced the recession, which will probably bloom during 2010.

In Europe and also USA the first half of 2010 will remain at about the current level or perhaps with a slight increase, which is believed will accelerate during the au-tumn of 2010 and even more during 2011.

There is a big need for replacement of equipment and if the signals are right the turn might become even stronger then expected. During part of 2008 and 2009 very few machines were sold. The contractors have used their old equipment as much as possible and have repaired old machines instead of investing in new. Diamond tools have dominated sales, even though that product sector also declined. The global concrete cutting machine fleet is in a poor shape, which also affects the quality and efficiency of concrete cutting services.

The lack of investment by the world’s concrete sawing and drilling contractors has impacted on manu-facturers. Sales of machinery have drastically declined leading to fewer new products being released during the year. Another reason the market has seen fewer new products is because manufacturers are holding off until the world’s biggest building machinery and equip-ment show Bauma in April. Similarly new products are expected to be launched at the forthcoming World of Concrete in February.

Cedima GmbH

The German manufacturer Cedima GmbH, which has a strong position in the eastern regions of Europe, as well as parts of Asia, has not released any new products

during 2009. The company may have some surprises for Bauma.

Demco

Swiss machine manufacturer Demco is an inventor of smart machines and devices for concrete sawing and drilling. During 2008 several new products were launched and the company is also believed to finalised the design of several new ones during 2009. But Demco does not shout about its new products until they have been thoroughly tested on sites by contractors. Undoubtedly there will be some of their new products at Bauma in hall A1.

DiaquipThe UK diamond tool manufacturer Diaquip has featured several times in PDi during 2009. Diaquip has for several years been in a strong position on the UK market as a producer of diamond tools. Since last year the company’s activities have increased radically selling diamond tools to almost all corners of the world. Besides its own produc-tion Diaquip is distributor in the UK for a number of machine and equipment brands. (See Diaquip feature on page 36).

EDT EurodimaSince EDT Eurodima became a part of German Roth-enberger Group it has been more aggressive. Lately the company has invested in improving its diamond tools. About a year ago EDT Eurodima launched the patented diamond tool Duramant. This has a new bonding and diamond mix, which improves both the efficiency and life of the tools and is now available both for blades and core drills. The manufacturer has also developed a new technique, Space Welding, taken from the automotive industry and gives extra strong joints between the diamond segments and steel.

Hilti

For new machinery for concrete sawers and drillers Hilti has been quiet during 2009, but there are rumours of a number of new products being released in the spring. During 2009 Hilti has strengthened its position in USA by acquiring the US diamond tool manufacturer Diamond B. Hilti has also released their new breaker TE 1000-AVR, which is lighter then its forerunner and has 50% more cutting performance and less vibration. Hilti has also launched a new handheld drilling system called DD 110-W. This machine is mainly for builders, carpenters and plumbers.

Husqvarna Construction Products

Husqvarna Construction Products is one of the few com-panies that have maintained a high pace of development throughout the year resulting in several new products. At the beginning of the year Husqvarna released the new dust reduction system Husqvarna WT 10. WT 10 makes it easy to cut wet even without any access to water on the site. WT 10 has a water tank, a Lithium-Ion battery, and

Main news at the end of 2008 was Husqvarna’s new remotely controlled demolition robot DXR 310. This is to be followed by the two smaller robots DXR 140 and DXR 250. (See page 43).

During the autumn of 2009 the company also released the new high cycle wall saw WS 482 HF (see page 20) that is the big brother to WS 440. New are also the drilling system with the core drill DM 340 and the drill stand DS 450. DM 340 is currently the most powerful core drill machine in the Husqvarna range.

ICS Blount

This issue of PDi features information on ICS. Besides the report about the renovation of the Den Bosch Cathedral in the Netherlands made with the assistance of ICS chains saws and diamond chains, there is also information on new products. ICS is releasing the new wall saw CWS-200, which combines ICS patented diamond chain technology with a new mechanized, rail mounted hydraulic drive unit enabling deep sawing without over cuts. CWS-200 is compact and light and easy to mount. (See page 20). Fairly new is also the concrete chain saw cutter 880F4, which is based on the new FORCE 4™ technology.

Pentruder

Another company that has accelerated during the crisis is con-crete cutting equipment manufacturer Pentruder. During the year the new production plant in Sweden was finished and a

customer event was held there in June. Several new subsidiaries have been started in various countries including USA, Sweden, Norway and UK.

Among the news for 2009 is the new drilling system that is compatible with the Pentruder rail system. The Pentruder range is steadily growing and contains five HF wall saws, including the new Pentruder CBK and the new wire sawing system Pentruder 3P8 and the new drill Pentruder Modular Concrete Cutting System. Anders Johnsén, the inventor and owner of the company says that once you have the complete Pentruder system you do not need anything more.

Soon to be announced is the completely new core drilling Pentruder Core EZ, which can be integrated with the new MCCS. This is new for coring as the power is placed in the centre instead of at the side (see PDi issue 3-2009). Further new products are a new and safer quick coupling for drills as well as a new connection box, which prevents electrical failures.

Pentruder is now working on some new attachments for the Pentruder system, like a chain saw module as well as a new flat saw range, which may be launched at the World of Concrete show.

Saint Gobain • Nimbus Diamond Tools

In 2009 Saint Gobain Abrasive marked its way in to the inter-national arena with several brands. The silent diamond blade Silensio has become a poplar product for cutting in sensitive areas. The company has also focused on their Nimbus Dia-mond Tools brand, containing models like V-Max, Avensis, Platinum, Titan and Proxy. Norton, part of Saint Gobain, has released a special device for reducing the diameter of a blade to fit various machines. The special device is called Quickfix and is available in two different sizes.

Another Saint Gobain brand is Clipper, which has re-leased the floor and road saw Clipper CS 451 as well as the new frame saw TR 250 HDF, which radically reduces the amount of dust when dry cutting.

Tyrolit

Also Tyrolit has been active with diamond tools by releasing several new models. The new diamond blade Tyrolit DCU*** Fastcut 4in1 cuts fast and can be used also for cutting steel. The blade is developed for dry cutting of concrete, stone, steel and other types of abrasive materials. It is available in diameters between 115 to 230 mm. The dry cutting core drill Tyrolit DDL*** has also been launched (see page 21) and the company has also introduced a new concept for core drills named CD***. Just before PDi went to press Tyrolit announced it was launching the new drilling gearbox (see page 20).

2010 is also the year when another edition of the popular and international Cutting Pro Competition will start. A num-ber of national championships will be held around Europe and the final will again take place in Innsbruck, 2011 (for more info see page 24-25).

WideCut

The diamond wire manufacturer WideCut in Korea is a manu-facturer we regularly feature. WideCut’s wires have become a ‘Rolls Royce’ in the industry. The company has recently added a new diamond wire to their product range. The new wire, marketed as HT-2, is designed to cut steel and heavily reinforced concrete. (See special report on pages 34-35).

The Chinese market

Chinese manufacturers have so far been inactive in the inter-national market. Most of the tools and machines produced in China are sold as OEM-products, with the exception of Sinoblade that has started to promote their products world wide as an independent Chinese brand. The full name of the company is Zhengzhou Sinoblade Diamond Tools Co., Ltd, which develops and produces a wide range of diamond tools for the concrete sawing and drilling industry.

Husqvarna has introduced the new electric wall saw, the WS 482 HF based on the same technology as the WS 440 HF launched last year, but can hold up to 1.6m diameter blades and is operated by radio remote control. It has a new two-speed gearbox combined with variable speed transmission, which allows the optimum speed to be set according to blade diameter, blade type and cutting material. Husqvarna’s new saw is light, flexible and extremely powerful. “The WS 482 is incredibly powerful. You get a total of

In the USA the chain saw manufacturer ICS has introduced the latest CWS-200 concrete chain wall saw, which combines patented ICS diamond chain technology with a mechanized, track-mounted hy-draulic power drive, allowing deep cutting without overcuts and less overall effort than other methods.

The CWS-200 is compact and light-weight and provides a one-tool approach to completing a full opening with square corners. The ability to mount the system to industry standard 360 track, combined with the capabilities of a chainsaw offers the advantages of increased cutting speed, increased chain life, improved ergonomics and significantly reduced operator effort.

The CWS-200 will easily integrate into operations using hydraulic power and op-erates with the hydraulic flow and pressure readily available from most professional power packs. After years of develop-ment and comprehensive field-testing the CWS-200 will be available for shipping in January 2010.

Tyrolit’s new drilling gearboxing on site has replaced the 32mm drill bit

mount. The high performance of the gear means that it can now be used with highly reinforced concrete. After

intensive testing, the product is now being used in the construction industry

worldwide. The drilling gear box can be used

with the existing system components from the wall saw range for drilling with high

frequency motors up to a diameter of 1m and for drilling deep holes that demand high

performance. This means that it is now possible to drill using electrical components where previ-

ously only hydraulic equipment could be used.

Tyrolit is launching a new concept in diamond core drills called the Premium*** range. The new drill

range, with CDL***, CDM*** and CDH*** models, guarantees better results, universal use and reliability under the harshest conditions, the com-pany claims. The drill concept has proved to be extremely competitive, safe and reliable in all operating conditions. The greatly increased drilling speed and smooth running are particular advantages when drilling steel.

New technological highlights are reflected in the novel drill con-cept. The system provides interplay of segment structure, shape and length to guarantee effective drilling. The core drill combined with Tyrolit Hydrostress drill rigs and drill motors

forms an integrated system, enabling users to work with high-quality products that

The new lightweight Tyrolit Premium *** DDL dry-drill bit requires very little pressure and reduces dust and drilling times. It is the ideal tool for the installation of sockets and junction boxes and smaller breakthrough jobs. A patented manufacturing process means the segments are now only 3 mm instead of 4 mm wide. This has allowed the size of the body and the weight of the drill to be reduced.

The drill bit is much lighter than conventional bits. The thinner segments and thinner body mean less stock has to be removed. Also less pressure is required and considerably less dust is generated. However, the real advantage is the extremely short

The aim of Design Trophies is to provide recognition for manufacturers launching new products designed in partner-ship with in-house or external designers. The award is based on three main criteria:

• To be new with a product on the market for less than 2 years• The products presented must be exhibited at the Batimat 2009 trade show• The efforts of the entire design team, in-house or outside, will be taken into account

New Pewmium*** diamond core drillsdeliver maximum performance on every hole. The drills have undergone extensive testing throughout their development at the Tyrolit Test Centre and with users around the world. All drills in the 47 to 1000 mm diameter range and a standard length of 450 mm are available and different lengths to suit customers’ requirements are available on request. Tyrolit offers extensive services for its Premium*** products. These include special versions and all standard diameters and lengths. Application sup-port is also provided for special projects, as are individual solutions for large construction sites and unusual challenges.

Less dust, shorter drill timesdrilling time. Locating the dust openings in the cover of the drill bit is another significant advantage compared with its predecessor. On the earlier model, these

openings were situated on the side of the body, which meant the drill bit could tilt over. The

fact that the openings are now integrated into the cover ensures that tilting is

a thing of the past with the new TYROLIT Premium*** DDL dry-

drill bit. If required, a suction hood can also be fitted to the cover to

allow an industrial suction unit to be attached and every last trace of dust to be removed. The result is no more time-consuming rework and a much healthier working environment for your workforce.

In the UK specialist diamond tools were vital for upgrading the sea defence wall at Weston Super Mare. The Plymouth Area Manager of contractor D-Drill, John Barber and his team, drilled over 4,500 holes over seven months to complete the work.

D-Drill had to drill holes through the granite and concrete of the sea wall to insert vertical dowels up to 3.5m deep. Also diamond saw cutting was required to form 1,338m of a rebate 100mm wide x 100mm deep to secure reclaimed granite copings to the top of the wall.

“Due to the poor state of the existing sea wall, continuous diamond coring barrels seemed to be the most effective method of achieving the required depths to enable the installation of new dowels”, says John Barber. “In this case conventional drilling

They learn and do their job in their dia-mond service contracting company on the job sites, in the practice training centre of the

SVBS, and at the professional school Beruf-sschulen Zofingen, www.bsz.ch. Zofingen is a small town near Zürich. The apprentices spend one week in every month at BSZ. An important part of the lessons concerns the diamond technique where the apprentices get their theoretical and technical qualification.

methods could have weakened the wall beyond repair, so the diamond tools used were crucial to the careful completion of the work”.

The work involved diamond core drilling 1,200 holes 78mm diameter and up to 3.5m deep in granite and concrete, as well as diamond core drilling 3,335 holes of 25-50mm diameter and 1m deep. The work required special Diaquip extended length core drills, which were custom made for the job and included Hydrostress HCCB professional diamond core drill rig, Partner hydraulic power pack, Partner Diamond Ring Saw and a Dimas 4 speed hydraulic motor.

Tyrolit seeks 2011 European Concrete Cutting Champion

European Championship final in Austria in January 2011.

First competition 2010 starts in ItalyThe first Tyrolit Cutting Pro Competition starts in Italy on 5 February 2010 within the Milan Architettura Design Edilizia at the Milan Fairgrounds, Rho. The Italian com-petition will last about half a day. Up to 26 are expected to participate in every national championship and selection will be by qualifying tournaments. The Tyrolit Cutting Pro Competition presents concrete cutting and drilling as a sports challenge. The ‘athletes’ will score with their know-how, speed, strength and enthusiasm.

Standard rules and regulationsThe Tyrolit Cutting Pro Competition uses a standardised set of regulations that allows for fair competition and inter-nationally comparable results. In addition, machines, tools, concrete and all other competition materials are defined and conditioned to guarantee that every athlete can compete on the same terms.

Exercises and productsAthletes compete against each other in the three exercises of wall sawing, core drilling and hand sawing. The time is taken for every exercise and the participant with the fastest total time wins. Every exercise is performed by two athletes in parallel, resulting in an exciting competition that is understandable and exciting for spectators.

depth of the first and second pass. On the other hand, the feeling of the athlete for machine, tool and concrete will be decisive.

The wall sawing system consists of the Tyrolit wall saw head WZ and the hydraulic power pack PPH25RR***. This directs the power of 25 kW by radio remote control onto the 825mm diameter Tyrolit diamond wall saw blade WSL***.

Core drilling: In this exercise the athletes have to drill a hole in a reinforced concrete block. With the start signal, the drill rig has to be mounted and motor plus core drill have to be fixed before the drilling can begin. The installation of the drilling system requires skill and experience. A fast drilling time will depend on applying the right pressure on the core drill.

For this exercise, a Tyrolit system consisting of the drill rig HCCB-5 and the drill motor DME32S*** will be used. The core bit CDL*** has a diameter of 102 mm.

Hand sawing: A disc has to be cut off from a concrete tube and speed and know-how of the athlete in dealing with the one-handed angle grinder are essential for this task.

The set-up consists of a petrol-driven, one-handed 5kW angle grinder that powers the 350mm diameter diamond saw blade DCU***. The cutting is done in wet conditions with the water directed into the cut over the concrete tube and not via the machine.

SafetyTo take part in the Tyrolit Cutting Pro Competition, the athletes must have proficiency and experience in the command of the machines and tools. In addition, the regulations specify the mandatory protective equipment for every exercise. On the stage, the movements of the competitors are limited to safety areas that are clearly marked.

For nearly 75 years, Terrco floor grinders and polishers have been the epitome of equipment durability. The 11-em-ployee family-owned company has specialized in products for tackling the toughest projects.

The rangeHeading Terrco’s heavy-duty product line is the direct-drive Model 6200, which is a manoeuvrable 1t machine with an eight-head, 1.38m wide disc sweep. Self-propelled with a 40-hp motor, the 6200 is ideal for tackling floors with an area more than 1,800m2. Smaller are Terrco’s direct dr ive Model 3100 and its belt-drive counterpart 3100-LP, both of which feature four-head, 660mm wide grinding paths. Both models use easily movable 19kg pocket weights to op-timize grinding pressure.

Even Terrco’s smaller grinders and versatile edgers are highly durable, a quality that company president Jim Vinella explains is essential, not only to provide contractors with lasting value, but also to accommodate both the expected and unexpected when on the job. “Rugged, direct drive equipment makes a difference, especially when removing epoxy,” says Vinella, who co-owns Terrco with his brother Peter, the company’s vice president and lead engineering expert. “It also means low maintenance, which is very important to customers. Nobody wants their machine breaking down repeatedly, or have to tear the gearbox apart every time they hit something.”

LASTING COMMITMENT‘When the going gets tough,’ the old adage reminds us, ‘the tough get going.’ And in the floor preparation busi-ness, ‘tough’ has come to epitomize floor grinding and polish-ing equipment manu-factured by the US company Terrco, Inc., of Watertown, South Dakota. PDi’s US Editor Jim Parsons reports.

Founded in Twin Cities 1936It’s hardly surprising that a company whose products have a reputation for ruggedness would derive its name from terrazzo, one of the world’s most durable types of building materials. Grandfather Peter F. Vinella started the busi-ness, originally known as Terrazzo Machine and Supply Company, Inc., in the Twin Cities in 1936. An Italian immigrant with a knack for mechanical problem solving, the elder Vinella developed machines that more efficiently handled floor grinding and polishing tasks his friends had

long done by hand.While Terrco’s growth

was built upon twin head machines, the company was among the first to offer four head models in the late 1960s. Another major technology jump occurred in the mid-1980s, when Terrco used diamond-tool-ing technology on their machines. Terrco currently offers diamond tooling for plug stone style holders,

universal tool plates, or speed shift plates. The patented speed-shift system facilitates fast tool changes, minimizing equipment downtime.

Relocating to WatertownTerrco itself made a more literal jump in 1986 by relocat-ing to Watertown, where the company currently occupies a 1,900m2 manufacturing facility with space for demonstra-tions and training. A network of nine agents and distribu-tors help give Terrco a worldwide presence.

This past year, Jim and Peter Vinella marked their 20th anniversary as co-owners of the company. The next generation of Vinella’s is already at work at Terrco, with the addition of Peter’s son, Frank, in 2008. “Frank is a mechanical engineering graduate, so the family tradition of tinkering is still there,” says Jim.

So too is another tradition of Terrco grinding equip-ment, which is productivity matching their solid construc-tion. The Model 6200 has a mastic removal rate of 140m2/hr, and a thin mill coatings removal rate of 167m2/hr. “That kind of performance ensures that contractors can get in, do the job, and get out quickly because time is money for even routine jobs,” says Vinella.

So imagine how important productivity is for larger, time-sensitive challenges. Take the case of a 6,500m2 concrete floor at a southern Louisiana shipping facility. Installed during the summer of 2008, the floor had been lost during installation due to the area’s high temperatures and humidity.

“Some of the variances were as much as 25mm,” says Vinella. “The owner first hired a contractors with 450kg grinders to level it out, but all they did was polish and make it prettier, not flatter.”

The owner then called in the Jim Sander Company,

This is how it should look like.

26 PDi • Issue 5 - 2009 • Dec 09 - Jan 10

LASTING COMMITMENTa San Diego, California based concrete floor preparation contractor, which suggested tackling the problem with Terrco Model 6200s. “We knew that the weight of the Terrco equipment would allow us to smooth the high waves out without affecting those low areas with the correct elevation,” says company president Jim Sander. “That was particularly appealing to the owner, because it meant they wouldn’t have to repour the concrete floor.”

Taking advantage of the owner’s scheduled Thanks-giving Week downtime, Sander’s level technicians worked 12-hour shifts with a pair of Model 6200s. Passes at 90, 45, and 90 degrees produced 9m2 of concrete dust, and a virtually perfect floor.

After seven days of rough grinding, Sanders’ crew spent a day blending and cleaning the surface, and removing scratch marks with 50 and 100 grit resin polishing pads. After hardening and densifying the work on Day 9, the floor was ready for the owner.

Sander has also put a Model 6200 to work on grinding and levelling a 3,440m2 slab at a defense support facility in San Diego. He reports that it took just six days for one machine working 8-hour shifts to get the job done, resulting in 3.7m2 of removal. “I don’t know of anyone that makes equipment bigger or more productive than Terrco,” says Sander. “The on-board computer lets you know if you’ve got the proper load weight for the job. It is amazing to think a machine can tell you that it’s OK to work harder if you want to.”

Foundation for the futureIt’s these kinds of fast-turnaround, cost-critical projects that Vinella believes will define the grinding and polishing industry for some time. Just as project owners want to get the most from their floor investment, Vinella hopes that

Issue 5 - 2009 • Dec 09 - Jan 10 • PDi 27

contractors will look to Terrco to get the most from their investment in equipment. “Surface preparation contractors need to be ready to take on any type of project, yet be able to do it as cost-effectively as possible,” he says. “Trying a quick fix with something cheaper or light duty won’t pay off in the long run.”

Concrete cutting contractors often face difficult tasks. The circumstances are difficult, weather is sometimes severe and sometimes jobs need to be done under water. A good example of difficult sawing and drilling is at the Fiskeby Power Mill in Sweden when a 1m diameter hole for a new cooling pipe had to be cut underwater.

More then a metre under the water level

It was one of those terrible cold and humid autumn days in Sweden with pouring rain. The concrete cutting contractor Haga R.O.T, based in Norrköping, had to cut a hole for a new cooling pipe to the plant’s heat-ing station. The cooling water for the paper mill is taken from an adjacent

river and Haga R.O.T. decided to us their Tyrolit hydraulic circular wire saw for the task. But the tricky job also needed some assistance from Tyrolit as well as diving help from the specialist diving company Yrkesdykarna i Norrköping AB, from Norrköping.

The hole was about 1m below the surface of the water. But the divers could not touch the bottom and had to cling to the vertical concrete wall in the very cold water. The approximate 1m diameter hole up to 800 mm deep had to be made through a concrete diaphragm wall attached to a small pumping house on the river bank.

The mounting of the Tyrolit circular saw was time consuming as it was done under water with zero visibil-ity in the muddy water. In addition to the circular wire sawing a couple of other holes had to be drilled for the new cooling pipe. The holes were 80 mm and 180 mm in diameter and about 3m deep. Cutting supervisor was Sean Sanders from Haga R.O.T. , which is one of Sweden’s biggest demolition and sawing and drilling contractors with 50 employees.

Diving help from YDAB

The divers Charlie Andersson and Karl Samuelsson from YDAB were indispensable. Charlie was mostly under water while Karl took care of the communication and the air supply. The water depth varied between 2.5 to 4 m and for this type of diving job a B-certificate in diving

was required. The whole sawing and drilling job was estimated at three days, including one day for mounting the equipment and drilling the holes for casting, one day for the circular sawing under water and another day for taking out the concrete core and cleaning up the site.

Equipment from TyrolitThe Tyrolit SL Hydrostress cir-cular saw used on the project was complemented with a Hydrostress CR-5 RC power pack. Tyrolit also supplied the DSG3 diamond wire. The mounting started with drilling

100 mm pilot holes for the saw’s swing arm and the part of the saw that catches the wire on the other side of the concrete structure.

To procedure to mount all parts of the circular saw on both sides of the concrete foundation and connect the diamond wire was time consuming due to the location and zero visibility. As the project schedule was tight Haga R.O.T. also used Tyrolit’s specialist Sonny Pettersson and salesman Fredrik Wikman to assist with mounting the saw. The final part was to attach and stretch the diamond wire. The actual circular sawing only took two hours without any interruptions. The main contractor Skanska and the Fiskeby Paper mill were very satisfied with the job.

The specialist American drill rig manufacturer E-Z Drill Inc, together with its sole European concessionaire Castellan Group, based in Milton Keynes, UK, has designed, built and delivered to site in just two weeks a special tailor made drill for use on a major M25 motorway widening project. The special drill has been brought in specifically to drill holes into the two sides of the existing Berry Lane Viaduct, just south of junction 18 at Rickmansworth, Hertfordshire, to accept tie bars to link into new reinforced concrete pier heads and an extended cast insitu reinforced concrete bridge deck.

Part of £6.2 billion projectThe seven span, 260m long Berry Lane Viaduct is a key structure on the M25 widening. It is part of a £6.2 billion project that will be designed, built, financed, operated and maintained for the Highways Agency under a 30-year concession by Connect Plus, a consortium of Skanska, Balfour Beatty, Atkins and Egis Projects SA. All work is scheduled for completion ahead of the 2012 London Olympic Games.

Specialist drilling and sawing contractor A J Will-cock (Holeformers) based in Hungerford, Berkshire, is working as sub-contractor for Skanska/Balfour Beatty on the Berry Lane Viaduct. The company is using its purpose built E-Z Drill 210B-42DD to drill hundreds of horizontal holes of varying diameters and depths into the exposed sloping edges of the existing bridge deck and pier heads. A J Willcock, using a combination of 1.2m and 2.4m long extension drill rods with the E-Z Drill 210B-42DD, is drilling 32mm, 40mm and 57mm diameter holes to depths of 750mm, 1.5m and 2.85m into the existing reinforced concrete to accept new steel tie bars, which are glued in position with epoxy grout.

Compact and wheeled drillThe compact, wheel mounted E-Z Drill 210B-42DD pneumatic drill uses a compressed air powered Con-solidated Pneumatic CP32 rock drill mounted in an extended frame increasing the rig stroke to 1050mm from the standard drill’s 450mm. An air motor, with an automatic brake, controls the chain drive drill feed system and the whole rig is powered by a 5.6m3/min, 690kN/m2 compressor. The rig is supported in a four legged frame mounted on wheels. It can be adjusted to accommodate the different heights of the holes from the working platform and quickly and easily

E-Z Drill assists with M25 widening

The purpose built E-Z Drill 210B-42DD is drilling hundreds of horizontal holes of varying diameters and depths into the exposed sloping edges of the existing bridge deck and pier heads.

A combination of 1.2m and 2.4m long extension drill rods with the E-Z Drill 210B-42DD are used to drill 32mm, 40mm and 57mm diameter holes to depths of 750mm, 1.5m and 2.85m.

The Wendelstein is a moun-tain at 1838m above seas level in the eastern part of the Bavarian Alps. It is the site of the meteorological observatory of the Deutscher Wetterdienst, the Ger-man Weather service and the observatory of the institute for astronomy and astrophysics.

The observatory’s 800mm telescope is being replaced by a new 2 m telescope and to set up this new telescope, the old base plates from the previous one had to be removed and a new substructure built.

The observatory was only acces-sible by helicopter, which took up the required machines, including two EDT Eurodima core drill systems, one wall saw WM50 with hydraulic unit HA150, one e lect ro-pneumat ic wire saw WB12S, a demolition robot and tools.

The lift station was cut by one floor and some further ceiling openings and door cut outs were made by a EDT Eurodima hydraulic wall saw WM50 and the hydraulic unit HA150. The telescope’s reinforced concrete pylon base was cut into 10 pieces by an EDT Eurodima wire saw and each part weighing about 1425 kg. The robot was also used and all demolished concrete removed by the helicopter.

The execution of the drilling and sawing tasks at the high altitude was dependant on good weather. Structural alteration works had to be done within a very tight time frame and completed before the end of September.

moved from one hole to the next. “I sat down with Castellan and told them what we

needed and within two weeks the drill had been built and shipped from E-Z Drill in the US and was on site drilling holes,” says A J Willcock proprietor Andrew Willcock. “It’s the only one of its type in the UK and is doing a great job and there is no risk of any hand arm vibration being transferred to the operator, who can use it all day long. I’m convinced it’s the only machine that would enable us to work in the confined areas on the viaduct and comply with the very tight programme. Backup has also been very good as every time I’ve needed some technical advice we’ve had excellent service from Castellan and E-Z Drill.”

When A J Willcock completes the drilling Skan-ska/Balfour Beatty follows on fixing and gluing the tie bars into the existing pier heads and bridge deck on the clockwise carriageway. When completed in November 2009 A J Willcock moved across to the viaduct’s anticlockwise carriageway for the entire identical process to be repeated and completed by the summer of 2010.

In addition to working on the Berry Lane Viaduct A J Willcock bought two other standard E-Z Drill rigs for use on widening another section of the M25 for Skanska/Balfour Beatty. The company is using the E-Z Drill rigs drilling over 80,000 holes 250mm and 300mm deep horizontally into the exposed vertical edges of the M25 pavement slab. The holes will ac-cept 20mm diameter tie bars glued in position with epoxy grout for keying on the new sections of concrete widening to the motorway’s existing carriageways. “We bought three new E-Z Drill rigs specifically for this major M25 widening project,” says Andrew Willcock. “We now have seven E-Z Drill rigs and the largest fleet in the south of England.”

As the world economy fell on hard times, many companies went on the defensive, slashing all investments and shun-ning any expansion ideas, just to preserve their hard-won market positions. This cautious approach may now seem what doctor Greenspan ordered, but whether they find themselves at the forefront of the industry when the recession is over, remains questionable. According to a raft of reputable business analysts and consultants, the companies that have chosen to increase their research and development and marketing budget during the crisis, rather than cut down on it, have a far better chance to spearhead the recovery and secure a better slot in the market than those who have opted to skimp and save.

New wire from WidecutKorea-based Widecut undoubtedly, belongs in the latter proactive category. Widecut is a specialist manufacturer that focuses exclusively on making premium quality diamond wires and beads

for construction and stone extraction industries. 2009 turned out to be just as gruelling for the Koreans as for any other in the industry, but at the height of the global slowdown Widecut took a bold and far-sighted decision to add another product to its already impressive range.

The new wire, marketed as HT-2, is designed to cut straight steel and extremely heavy

reinforced concrete. Steel cutting with diamond wires is a relatively new business, which nonetheless harbours strong potential.

So far, this segment has been all but monopolized by a few major European companies. Widecut entered into the scramble by introducing a product to rob the Europeans of their previously unchallenged dominance. “When developing HT2, we aimed to not

just enhance our position on the global market, but rather we were chasing a dream of creating a wire capable of solv-ing the most demanding and imagina-

tive demolition tasks,” says Widecut president John Han. “The diamond wire technology was first invented to extract stone at quarries, then it was upgraded to cut construction materials. Likewise, our wires, which are built to cut regular building ele-ments, may soon be able to take down a structure of Godzilla proportions. I look forward to one day seeing something like an entire metal bridge being cut in one sitting with a Widecut wire.”

Many structures made of steel

Steel is second only to concrete for use in construction. There are many structures made solely of steel, such as bridges, han-gars, water tanks and furnaces. Custom-ized diamond wire can become a tool of choice when dismantling or altering steel structures. Steel cutting is often required during decommissioning or rehabilita-tion of nuclear or hydropower plants and offshore oil installations. The hull of a salvaged ship, out-of-service submarine or aircraft can be sliced up like a slab of cheese this technique. There is ample opportunity to make use of steel-sawing

wires, and many suppliers see this business as very lucrative. In Widecut’s estimation, global demand for this particular tool currently reaches 6,000 to 8,000m/month.

Specific manufacturing challenges

The manufacturing process for steel cutting wires has its specific challenges, which many producers of diamond tools still tend to shrink from. The key to efficient steel cutting is a bead with very high concentration of diamonds in its working layer. At the moment three basic approaches towards bead making exist. These are sintering and brazing, which are high temperature processes, and electroplating. Sintered beads are believed unable to cut steel structures of any substantial size due to insufficient concentration of diamond particles. Conversely, brazed and electroplated beads, both having higher diamond content, have proved more suitable to large steel cutting jobs. However, in Widecut’s experience, the electroplated wires show superior performance to the brazed ones. An electroplated bead consists of a steel core with a single high-density diamond layer deposited on it. The layer surface should be as even as possible, its cohesion with the steel substrata very strong. If these vital criteria are not met, diamonds will chip out under extreme friction soon after the wire is put to work. So far, only a handful of companies in the world have successfully harnessed the electroplating technology for diamond tool production. With HT2, Widecut slipped seamlessly into their privileged ranks.

Widecut’s HT2, which is complete with 2° conical electroplated beads, is available in two of 40 and 48 beads/m. The 40-bead specification allows for fast cutting, while the 48 one is designed for extended life. When the manufacturer pilot tested HT2 against a number of com- To the right John Han inspecting a fresh batch of wire.

petitive brands, it outperformed them all in cutting speed and durability. “Before HT2 came along, a notion persisted in the market that only tools of European origin were good enough for difficult tasks like steel cutting,” says John Han. “We managed to dispel this preconception by offering a product, whose quality even the staunchest advocate of European standards could appreciate.” Widecut’s produc-tion capacity for HT2 is 800m/month at the moment, but the manufacturer looks to increase it up to 1,500m by early 2010 to meet the growing demand.

A lot of Diaquip’s success is down to the company’s focus and dedication to the concrete cutting market. There are very few companies committed purely to the manufacture and supply of concrete cutting products, and 12 years ago, the partners of this family business saw a gap in the market. Now, this development and un-distracted focus on all things concrete cutting has paid off.

ManufacturingDiaquip have found a unique competitive edge, by manufac-turing in house. This gives the company greater flexibility than most, and allows it to be more competitive as they are avoiding the costs of manufacturing abroad. Importantly, it also means Diaquip can offer an unrivalled service. The technical nature of concrete cutting often demands a bespoke product and when needed, Diaquip can supply it.

Product Development

When it comes to developing products, Diaquip are at the forefront. They seem to take a practical, on-site approach to de-veloping products, testing where it matters the most out on sites. There is a constant stream of new and developed products coming as Diaquip try to take concrete cutting technology further. New products are tested in a comprehensive research and development area, set up alongside the plant in the UK. This contains every concrete cutting eventuality likely to be found on sites with all types of aggregates, including a large slab of 50N flint concrete, full of steel rebar. Many hours have been spent here, developing the Aero® range that is now so well known.

Aero® Range

The introduction of Diaquip’s Aero® range has taken concrete cutting to a new level. The totally unique core drill segments were first to arrive, with the ‘golf ball’ effect and Aero® FW, W shaped segment. Research and development staff soon found that the increased water coverage and reduced fric- tion was allowing the segment to cut significantly faster than any other segment in most situations. The Aero® Wave hand saw and ring saw blades soon followed, quickly proving their performance. One of the biggest steps forward was the Aero® Matrix technology, with diamonds positioned in the floor saw and wall saw blades in a honeycomb effect, ensuring more diamond constantly on the surface of the segment making for a smoother cut. These products are unique, and it is constant research and development that has meant Diaquip are well ahead in concrete cutting technology.

In a time where service standards are known to be dropping, Diaquip are refusing to compromise on their values.

Global MarketsDiaquip are successfully moving into international markets, with the Aero® range. With a wide range of specifications, and flexibility in manufacturing, they can offer a sterling service to distributors in countries all around the world. Now experienced in exporting, Diaquip can offer very quick delivery times to Eu-rope and worldwide. Diaquip is currently looking for distributors in some countries currently not covered.

Overview

There is no doubt that Diaquip is leading the market in the UK and abroad in concrete cutting equipment. From our observa-

tions it will stay that way for a very long time. There are few companies willing to put all their focus on concrete cutting products, but this one has, and is leading the market and showing no signs of letting up.

SPE International also known as SPE Group was founded by Tony Mansfield in 1983 and is owned by the Mansfield family. The group employs 150 workers and has its produc-tion plant in Lincoln UK. The company has four UK based group companies, eight overseas companies trading as SPE franchises and a network of distributors selling SPE products but trading under their own names. The main markets are UK, USA, Middle East and Asia.

The product rangeSPE Group states that they are one of the largest indepen-dent manufacturers and suppliers of surface preparation equipment in the world. They have one of the largest ranges of products available form one source. The complete range includes Autoblast enclosed shotblasting equipment, floor grinders, floor scarifiers, stripping machines, hand tools, ride on multi purpose equipment, dust control vacuums, diamond products, HCA equipment, open blasting, mixing equipment, airless spray and wet concrete equipment.

New developmentsThe latest developments are the MP6000 Ride On multi-purpose machine. It consists of a diesel powered platform with shotblasting, scarifying, grinding and stripping attach-ments. Launched in December 2009 is the DFG200 single head single phase diamond floor grinder.

SPE clients are first of all found in the construction industry, flooring contractor, demolition contractors, rental

industry segments. Tony Mansfield’s opinion about the market share for polished concrete as a final floor product is that it has grown and is now a realistic option.

“It is still not that popular in the UK though due to cost, the complexity of operation, possible problems with quality of concrete and other resin based alternatives. But the concept has proven successful in the USA probably due to the size of the flooring market place,” says Mansfield.

Mansfield continues to say that resin is still most popular for industrial applications and traditional tiles, vinyl etc for commercial applications but polished concrete is gaining ground fast.

“Polished concrete floors have potential, but I think the cost still is too high compared to preparation followed by applied materials. The consistency of finish will vary greatly if the concrete has not been mixed and laid with a view to being polished at a later stage.

“But polished concrete seems to be specified more often by architects in the design stage. However, from our experience when it gets to the production stage the concept becomes less popular. We have been involved in surface preparation for over 25 years and seen a steady increase in this side of the business. Polished concrete is a relatively new concept and has grown by being specified at the design stage”, Mansfield adds.

New SPE Floor GrinderSPE is pleased to announce the launch of the DFG 200 .The new machine is a compact single head unit developed as an introductory model to the SPE DFG Floor Grinder range. Simple to operate and available in single phase electric the DFG 200 meets the requirements of rental companies and flooring contractors. The operators handle height is fully adjustable and the machine fits easily into the boot of a car for transportation. The machine can be fitted with a wide selection of diamond, polymer and PCD attach-ments providing a versatile solution for smaller surface preparation projects.

Special features: Robust construction, 50mm dust extraction port, Dust free when used with suitable SPE dust control vacuum, Large diameter wheels for excellent mobility and stability, Removable weight to vary grinding pressure, Simple adjustment to level to the floor surface, Adjustable dust skirt

Applications: Accurate grinding of concrete surfaces, Removal of old floor coatings and contaminates, Latex and adhesive removal, Grinding and polishing of resin

based and tiled terrazzo, Remedial work to rain and frost damaged slabs

At World of Concrete 2010 in February there will hopefully be another spirit on the exhibition floor then at the event in 2009. The numbers of exhibitors are down in 2010 but that they were up in 2009 was probably that it was too late to cancel. The recession came as a thief in the night so to speak.

World of Concrete 2010 returns to the Las Vegas Conven-tion Center, February 2-5; Seminars 1-5, and will continue to build upon a reputation as the only annual international commercial construction show for the concrete and ma-sonry industries.

“While exhibitors drop in number visitors might increase”

World of Concrete 2010 will showcase, according the list of exhibitors, at press stop, some 1300 indoor/outdoor exhibitors. In 2009 the number of exhibitors that had

reserved space were approximately 1800. But some of them did not show up at the show. The 2010 edition of the show might look at a loss of some 500 exhibitors depending on the booking situation during January. But no blame on World of Concrete as a show it is purely the economical situation that has created this reaction among the exhibitors. World of Concrete is a very well organised show and attracts ten’s of thousands of visits from the whole world every year. World of Concrete is the show when it comes to equipment for concrete sawing and drilling, demolition, concrete floor preparation, demolition and recycling worldwide.

The organiser is his year looking at around one mil-lion gross square feet of exhibit space with more than 100 educational sessions, product demonstrations, spectator competitions and forums providing relevant solutions, products and technologies to WOC attendees.

Were everything happensWOC is recognized by Tradeshow Week as one of the fastest 50 tradeshows in both 2007 and 2008, this 36th edi-tion of WOC will feature special product and action areas including The Producer Center, a dedicated marketplace of materials, equipment, demonstrations, and seminars for concrete producers; Material Handling, offering trucks, excavators and more for material delivery, distribution, concrete placement, and earth moving; Concrete Repair

WELCOME TOOUR KIND OF PLAYGROUND

OUR KIND OF PLAYGROUND is often a very dangerous environment and there are no good arguments for exposing you or your staff to falling debris or dangerous vibrations.Our demolition machines are radio controlled and electrical-ly driven so that you are not exposed to dangerous fumes. Another thing which makes the machines even better is that you can demolish up to 5 times quicker than tra-ditional sawing and cutting methods. Time is, as we all know money!

Singapore is building a large hotel and casino on reclaimed land and the soft ground conditions create major challenges for the foundations. Thick diaphragm walls had to be built and part of them had to be demolished after placing the foundations. This was a tough job to test the first Brokk 400 in Asia.

Deep diaphragm walls had to be installed before the area could be excavated. It was decided to build small cofferdams with diaphragm walls for each of the hotels as they could be excavated without struts. After the underground complex had

been excavated, the temporary diaphragm walls separating the hotel basements had to be demolished. Technocrete Pte. Ltd., one of the leading specialist demolition contractors in Singapore,

Brokk 400, a 5t radio controlled, electric machine with 1000 joule impact energy in every hit.

Two diaphragm walls with steel struts in between for stabilization.was awarded the contract for all demolition work. The diaphragm wall demolition could only be done after all basement floor slabs were in place. The headroom between floors was only 3m and the diaphragm wall was 1.5m thick.

Technocrete proposed a combination of wire cutting and breaking methods to demolish the diaphragm wall. Wire cutting was used whenever both sides of the diaphragm wall could be accessed and there was room to l i f t out the cut blocks by crane. All other remaining parts were demolished using hydraulic breakers.

Technocrete had two Brokk 330s. However, the two ma-chines were not enough to meet the schedule and company brought in several 5t Airman AX45 mini excavators to speed up demolition. But, after problems with the mini excavators, Technocrete decided to purchase two Brokk B400, Brokk’s biggest demolition machine.

The 5t Brokk 400 is electrically powered, radio controlled, and equipped with a three part arm system and equipped with a 520 kg breaker with impact energy of 1048 joule. During initial deployment, Brokk carried out a performance test on a section of wall 6m wide, 4m high and 1.5m. The test took about 9 hours to break out 36m3 of concrete at an average rate of 4m3/h. Technocrete took about three days to complete demolition of this type of wall, including cutting the reinforcement and remov-ing all the debris. This was estimated to be around five times the performance of the mini excavator of similar weight.

In 2010, Bauma, the International Trade Fair for Construction Machinery, Building Material Machines, Mining Machines, Construction Vehicles and Construction Equipment, is set to attract the highest number of exhibitors since launch. Accord-ing to the latest plans, there will be space to accommodate more than 3,000 exhibitors.

Extends space with temporary hallsThe higher capacity is due to extra space in temporary halls on the open-air site, from new and existing joint stands and some regular exhibitors altering their space requirements. Nevertheless it will not be possible to meet in full all the requests for space. “We are particularly pleased about the level of interest from Chinese, Turkish and in particular the Indian exhibitors, India being the partner country of Bauma in 2010,” says Exhibi-tion Director Georg Moller. “In some cases we have received double the number of requests for exhibition space from these countries than in 2007.” Exhibitors from Europe, for example, Italy, Great Britain and the Netherlands, will again be taking the top slots in the international exhibitor ranking.

All this is a strong indicator that the industry worldwide is looking forward with confidence to the leading world trade fair, Bauma 2010, which takes place from 19 to 25 April 2010 in Munich.

Prospects for the building and construction industry

worldwide in 2010Thanks to extensive government economic stimulus programmes, activity in construc-tion has picked up in most industrial and emerging countries than the economy as a whole. For 2010, but increasingly so for 2011, it is expected that most countries will see a revival in activity in the building and construction sector.

In Europe a slight fall of 1% in building production is still expected in 2010. But this is due solely to the poor development in commercial construction. Civil engineering, by contrast, is expected to grow by 2.7%. In 2011 building investment is predicted to expand by 2% Europe-wide, again driven by investment in civil engineering projects, contributing 3% growth. The slight

downturn in production in 2010 is due to the negative effect from countries where prices have fallen dramatically. In the reform economies of Central Europe, however, growth in construction activity is set to expand by 6% as early as 2010, accelerating to 10% in 2011. The engine behind this growth will continue to be Poland.

In Russia building activity has increased considerably during the last decade. In 2008 the Russian construction reached a volume of around EUR130 billion, which is 11% of GDP. Building activity has stayed stable in 2009. However, a downturn of around 5% is expected for 2010, followed in 2011 by modest growth.

At around EUR730 billion, the building and construction market in the US remained the most important in the world.

Following a downturn in the current year, real GDP is expected to rise again in 2010, by 1.5%, indicating that the US is emerg-ing from recession more quickly than expected. Following the severe drop in building production in 2007 to 2009, a slight increase is expected next year, picking up strength in 2011. Government building activity will increase, particularly in civil engineering projects. New residential construction is expected to stabilise, while a more marked downturn is expected in

commercial construction.Following exorbitant growth in

the last 15 years, China’s volume of building investment reached around EUR550 billion in 2008, making it the second largest building market in the world. The Chinese govern-ment has launched wide-ranging economic stimulus packages with a focus on investment in state infrastructure. Overall China is coming through the global economic crisis much better than the industria-lised and emerging econo-mies. Economic research institutes are expecting real GDP in China to grow by 8% in both 2009 and

2010. In building investment the

growth is likely to be slightly higher, as the Chinese govern-ment is holding firmly to its ambitious investment programme in infrastructure.

The level of investment in the Indian construction market is around EUR130 billion. However its rate of growth was almost as impressive as China. Between 1998 and 2008 activity in build-ing and construction rose by around 140%. And this dynamic pace is set to continue. According to forecasts by the economic research institutes real economic output in India is set to expand by a 6% in 2009 and 2010. In the current Five-Year Plan, to 2012, aroundEUR330 billion is being invested in the expansion of the road and rail network, the construction of new seaports and airports and improving energy and water supplies. During this period growth in investment in construction is expected to reach around 10% a year.

Bauma in briefA record 555,000m2 and more of indoor and outdoor exhibition space at the New Munich Trade Fair Centre is dedicated to a display of the latest products from the international construction, building-materials and mining machinery sectors between 19 and 25 April 2010. More than 3,000 exhibitors are expected to make use of this event.

Having successfully completed the demolition of the former 21 storey Maths Tower at the University of Manchester in March 2006, the UK demolition contractor Connell Brothers Ltd has returned to demolish the 14-storey Moberley Tower and Refec-tory. The University is host to approximately 35,000 students from all over the world and employs in excess of 11,000 personnel.

The demolition project is at the heart of the campus, surrounded by historical buildings and in close proximity to the famous John Rylands Uni-versity Library, the Samuel Alexander Building, the

Students’ Union and fronting the busy city centre arterial route of Oxford Road.

The 32 week demolition

Back to University for Connell Brothersproject forms part of the University’s plans for a new Learning Commons at the heart of the campus. The demolition of the tower and refectory will open up the area allowing for the planning and future cre-ation of a flexible learning space that will provide integrated learning environments supported by advanced technologies.

The project is contained within a restricted footprint where the 14 storey tower and refectory building have been encased by scaffold. The tower is being dismantled floor by floor, using specially equipped mini-excavators working at roof height.

The west refectory building demolition started with high reach machines opening up the site for ac-cess to the tower. In opening up the site the side walls of the structure and scaffolded sections w e r e retained as a protective barrier. Once the tower has been dismantled to

The team from the German demolition and blast-ing contractor Philipp Halter GmbH & Co. of Berlin was faced with a challenging job of demolishing in only 48 hours the southern section of the Spandau dam bridge crossing the A 100.

The factor that played a decisive role in the swift and smooth demolition progress was the interaction of Atlas Copco hydraulic breakers and hydraulic CombiCutters. First a bed of sand was placed underneath the bridge to allow the girders and reinforcements taken down by the Atlas Copco CombiCutters to be remove.

Three MB 1700 hydraulic breakers began with the preparations on the bridge foundation. This medium weight range breaker weighing 1.7t,

is suitable for carriers in the 19 to 32t weight class. An SB 302 was used for the preparatory and finishing work. This light hydraulic breaker weighing 304 kg is suitable for carriers in the 4.5 to 9t class.

The main part of the work was handled by two Atlas Copco hydraulic CombiCutters, a CC 1700 U and a CC 2500 U, both equipped with universal jaws, which crushed the concrete and cut the rebar in one go. “We cannot make compromises with regard to reliability,” says Philipp Halter chief executive Christoph Halter. “The performance of the Atlas Copco products has convinced me to such extent that we will definitely rely on them for future jobs, too.”

Thanks to the interaction of Atlas Copco hydraulic breakers and CombiCutters the old dam bridge is now history and has made way for one of the most significant roadwork projects in the capital on the banks of the Spree.

a suitable height, the high reach ground based machines carry out the remaining demolition.

Connell Brothers adopted a flexible approach to the planning of the works and any items that have an impact on noise, vibra-tion and vehicle movements were scheduled for completion out of normal University operating hours at night and weekends. The work is progressing toward the targeted date for completion at the end of March 2010.www.connellbrothers.co.uk

Back to University for Connell BrothersHusqvarna’s demolition robot DXR 310 has played a crucial role at a major refurbishing project at one of the USA’s largest military bases at Fort Benning in Georgia. Supported from a crane, the robot successfully demolished a six-storey brick building. Atlanta-based demolition com-pany B&D Concrete Cutting was contracted by Winter Environmental and McCarty Corporation to work on the extensive renovation project. The mission included taking down the brick facade of a six-storey concrete building, without damaging the concrete framework.

B&D Concrete Cutting chose to use Husqvarna’s new remotely controlled demolition robot DXR 310 for the task. Putting the demolition robot on a frame and winching it up in a crane, the DXR 310 could do the job with the operator safely in a boom lift. “I have been running robotic machines for years, but this was the first time it was suspended from a crane,” says, at B&D Concrete Cutting superintendent Chris LeBlanc. “With other robots, you would have to downgrade in hitting power to get that compact size.”

Another challenge was refurbishing the seven stairwells in the building. Thanks to the telescopic boom of the Husqvarna robot, which has a range of approximately 5.5m, it was possible to reach inside the doorways. The individually controlled out-riggers were very useful in the tight locations where it was not possible to use all four. “Without the extended reach of the DXR 310, we would not have been able to demolish the stairwells. Using the telescopic boom, we could do two

floors at a time, without having to move the machine,” says Chris Leblanc. “With just a touch of a button you can activate a

function and monitor temperatures or problems with the machine.”The demolition project at Fort Benning was finished at the end

of September and ahead of schedule. “Our customer was extremely satisfied with the job our company did, and we could not have done it without the DXR 310 and the support of Husqvarna,” says B&D Concrete Cutting owner Michael Tackett.

Hunt makes way for £600M development

The specialist UK demolition contrac-

tor John F Hunt Demolition is using

one of its purpose built 42m, high

reach excavators, fitted with a con-

crete cracker, as the principal equip-

ment to demolish several residential

tower blocks in Canning Town, East

London, as the first phase for a vast

£600M redevelopment of the area.

The long reach Hitachi with 42m boom proved ideal for the top down controlled demolition.

John F Hunt’s Hitachi Zaxis 870LCH, is being used to dismantle high rise tower blocks piece by piece. This 105t unit is comple-mented by two of the company’s smaller Komatsu PC210LC and PC450LC excavators, which assist when the partially demolished structures are within their reach.

Started in the end of OctoberJohn F Hunt Demolition, working as principal demolition con-tractor for London Borough of Newham and London Thames Gateway Development Corporation, started on its £1.5M demo-lition contract towards the end of October adjacent to the main A13 Newham Way trunk road and its junction with the A1011 Silvertown Way. The company initially and quickly dismantled the low-rise four-storey block of flats in Rathbone Street, prior to embarking on the first of the three remaining adjacent 11 storey blocks, Swanscombe Point.

As a symbolic end to the high-rise tower blocks and the start of the huge Canning Town and Custom House Regeneration Programme, one of Canning Town’s oldest residents, 89-year-old Alice Lashmar, was invited to join the John F Hunt Demolition team to start the demolition of Swanscombe Point. Alice, who will be 90 next April, was born in Canning Town and has lived there all her life. She worked from the age of 14 to 62, with 15 years in the Canning Town Labour Exchange and many more in the civil service. “I have lived in Canning Town all of my life and have many fond memories of the town,” said Alice. “I have seen it go through a lot of changes over the years and it is about time the area was spruced up a bit so that future generations can reap the benefits and enjoy living here as much as I have.”

With that Alice sprightly climbed up into the cab of John F Hunt’s Komatsu PC210LC, equipped with concrete crusher, and sat at the controls posing for photographs and interviews with television crews for broadcast later on the local television news programmes.

42 m reachFollowing the photo call John F Hunt Demolition’s site team set to work with its 42 m high reach Hitachi 870LCH and made a start on taking down the 11-storey Swanscombe Point tower block. Working from the top down, the Hitachi, complete with its 4.5t fully rotating Caterpillar MP40 concrete cracker, started on the top roof slab. The control and accuracy of the Hitachi operator’s skill at positioning the concrete cracker at high level enabled the machine to gradually and accurately chew its way down the building, effectively dismantling the condemned structure in a controlled piece-by-piece operation. “The long reach Hitachi is ideal for this type of top down controlled demolition,” says John F Hunt Demolition project manager Irfan Quraishi. “The machine can stand well back from the building and dismantle it floor by floor and piece by piece. When we get closer to ground level we can also bring in the other two excavators with pulverisers to complete the demolition. We expect to take a couple of weeks to dismantle Swanscombe Point, before moving onto the remaining two high rise blocks.”

Swanscombe Point and the other tower blocks are part of a 16 acre Brownfield site that is being cleared to make way for 1,100 new homes and 60,000m2 of retail and office space and leisure complex. Swanscombe Point will itself be replaced by and make way for a new supermarket, over 200 homes and a leisure facility. It is all part of the Canning Town and Custom House Regeneration Programme, which is a partnership between Newham Council and the London Thames Gateway Development Corporation. The programme also includes the building of up to 10,000 new homes and two improved town centres and is expected to generate £3.7billion of additional investment and physically, economically and socially transform the area.

Hunt makes way for £600M development

One of Canning Town’s oldest residents, 89-year-old Alice Lashmar was interviewed by the local BBC television news.

All waste recycledAll the rubble and debris from the demolition will be sorted and recycled on site. John F Hunt Demolition will then bring in one of its own mobile crushers to crush and screen the hardcore and concrete. This will then be spread around the site in a thick blanket to provide a working platform for the piling rigs that will be needed to construct the foundations for the new structures.

John F Hunt Demolition is scheduled to complete the dismantling of the four structures by Spring 2010. Developer Bouygues UK will then follow on and make a start on the next phase of the regeneration programme and develop the new Can-ning Town centre over the next 10 years.

“We still need to educate customers about what our equipment can do and how customers are able to benefit from them. The difficulty is that many of our products are the first ones and they change the old working patterns and procedures. It just takes time to get the new methods sold to customers,” says Pylväs. “We are now experiencing a recession, but I’m confident that better times will come again and that Allu will continue stronger and larger as ever.”

In particular, there are two product lines that have been the first in their respective fields and where Allu has been the undisputed pioneer. One is the screener-crusher material process-ing device and the other is the mass stabilisation system. In both cases Allu is the global market leader with a huge margin to the competition

The crucial customer need Allu started in 1985. The founding father was and still the in-novative mind behind the research and development is Markku Jonninen, a mechanical engineer who was employed by companies selling crushing machinery. However, he decided to move into his own business of importing machines and tools for forest and bio energy industries. Amongst the imported machines were chip crushers and the idea for the name of his new company Ideachip. In addition to mere import, Ideachip and Markku Jonninen also designed machines and systems. He designed the whole handling process of sorting wood chips. The company soon became involved in waste management equipment and handling of demolition debris.

Then in 1991Ideachip experienced the turning point in the company’s short history. Ideachip and Markku Jonninen had a customer who handled all sorts of soil materials using a stationary screen. However, the customer was not satisfied with the machine as wet material blocked the screen. He asked Markku Jonninen for help who came up with the idea of a bucket-type screener-crusher, the first of its kind in the world. The product was branded Allu.

“The screener-crusher was an ideal solution for soil handling. It is basically a bucket that is attached to the excavator boom or to a wheel loader. In addition to solely screening and crushing, the screener-crusher can also be used for mixing, aerating and loading the material, even for separating various materials,” says Pylväs.

“With a screener-crusher the customer gets many advantages. First, the investment is cheap in comparison to, say, a standard stationary screen, and from the point of view of daily use, the screener-crusher offers so much more versatility. Allu’s estimation is that we have a 60 to 70 % global market share in this line of

Allu expects a hugemarket potential

equipment, and naturally we want to keep it that way.”

Hornets helpedIn the early 90’s a major recession hit Finland and other Nordic countries. Ideachip experienced a huge decrease in sales. Markku Jonninen decided to start designing Ideachip products that would increase the range and enlarge its customer base. The screener-crusher was the first one in 1991 and the windrow turner followed a year later.

In 1993, the American made Hornet fighter planes further helped Ideachip’s situation. The Finnish government ordered Hornet fighters for the Air Force, and the deal included the offset trade system, whereby the seller purchased Finnish made products. Ideachip was the very first Finnish company to benefit from this agreement by signing a delivery agreement of one big windrow turner. The deal was worth approximately EUR500,000 in today’s value. However, at that time it was a lot more and more impor-tantly, it was a real reference delivery to the US market. The Allu windrow turner is now one of the most appreciated machines in the USA for bioremediation of contaminated soils. With the recession over sales picked up and by 1994 Ideachip’s sales included 50% of its own products and 50% from other producers. It was time to start searching for dealers as export business increased steadily. In 1997 the company had active dealers in about 10 countries.

Cat experienceA few years later Ideachip thought the company had found the solution for the demand of growth. Caterpillar had shown inter-ested in Allu products and, in 1997 the two companies signed a deal covering 124 countries. But the deal did not go as planned. The contract was made between Ideachip and Cat Work Tools Division, which meant that Ideachip’s only working partner, was the Tools Division, and Ideachip did not approach Cat dealers directly. So the Cat dealers were not motivated and trained to sell the new and then unknown tool and sales were disappointing. There was another complication. In some countries the local Allu dealer discontinued the dealership. In Germany the previous dealer designed a screener-crusher of its own and started to compete with Allu and Allu screener-crusher sales in Germany temporarily dropped dramatically.

New face and new methodIn 1999 Ideachip recruited Kauko Pylväs as managing director. He had a lot of experience in international business and in developing global sales networks. The same year he decided that the only way to grow the company business was, instead of relying only on the Cat network, to further develop the company’s own sales channels. Consequently, Ideachip started to create its own dealer organisa-tion. It paid off, as the company’s sales have grown an average of 25% annually and many Caterpillar dealers now also sell Allu products independently.

In 2002 Ideachip launched a new product line, the mass stabilisation method and was the first time the process like this could be performed by one machine. Now mass stabilisation has been used almost all over the world on many different projects. In the USA for instance in New Orleans where some of the levees and other earth structures have been stabilised to better withstand future hurricanes. Another project is in Florida where 14.4 km along the sides of the Key West main road was stabilised so it could be widened from two to four lanes. This was done to ease the evacuation in case of a hurricane emergency. Other major stabilisation projects include the ring road of São Paulo in Brazil, the enlargement of the port of Valencia in Spain and the port of

Allu, the Finnish manu-facturer of a large variety of products for soil treatment and improvement purpos-es, expects a steady growth in its world-wide sales and opera-tions. The company is now well over 20 years old, but according to managing director Kauko Pylväs, it is still in the phase of taking the first steps.

Vuosaari in Finland. “There are now many stabilisation systems sold and several

interesting prospective projects. One application is the cleaning of oil drilling holes. All over the world at oil production sites there are thousands of holes waiting for a major clean up. Another in-teresting case is in the UK, where there are quite a few abandoned dockyards that need stabilisation for a new use, such as housing and commercial projects,” says Pylväs.

Allu – after all…Further changes within the company took place in 2007. While the company name was originally Ideachip, the brand of the company’s own products has always been Allu. Two years ago also the company changed its name to Allu to streamline the company’s global image and identity. All over the world the Allu name is also used by its subsidiaries. The sales organisa-tion now relies on subsidiaries in Germany, France, UK, USA, China and Argentina and strengthened by about 30 dealers in further countries. The other major change was a move to a new building. The company had always been close to Lahti in southern Finland, but the old building did not provide scope for expansion. Now a brand-new ultra-modern manufacturing and office building covering 6.000m2 was built 30 km south of the previous headquarters. It also offers space for further expan-sion if needed. Allu now has about 100 employees and sales of approximately EUR25M.

Education, pioneering…In spite of the company’s success, Kauko Pylväs emphasises that there is still a lot of work to do.

“Although we have been present at almost all the major trade exhibitions and always demonstrated the equipment, there are a lot of people who come to see us and wonder what the products really are about. In fact, most people don’t have a clue. ‘Awesome’ and ‘cool’ are the words you most often hear when the visitors are watching the Allu demonstration. Indeed, to some even the screener-crusher is a new product and a new concept,” says Pylväs. “So there is still a long way to go for the Allu team.”

Allu – 150 million years old but still youngAllosaurus was the most frightening carnivorous animal of the late Jurassic era, approximately 150 million years ago. It was the largest member of the Allosaurie family. Allosaurus weighed about 4t and height of 5m when standing on its hind legs. Palaeontologists believe that the animals were fast and hunted huge herbivorous animals and ate all kind of waste as well. Markku Jonninen, the founding father picked up the name of allosaurus, but modified it to Allu. Today Allu represents a powerful device, which can effectively and simultaneously eat, treat and digest various waste materials.

In remembrance of a dear friendOn 17th December 2009, my friend and employer, Yury

Mokin, passed away in Saint Petersburg in a most tragic

way. He was 42. Days go by, but the pain shows no sign of

subsiding as I am trying to fathom how this could happen to

such a vibrant and strong young man. When I mentally came

to terms with the ruthless fact, I first thought of publishing a

rather formal “in memoriam” notice to the world’s concrete

sawing community in PDi magazine. I intended to write a

story, which would tell people about his background, his

track record and achievements. But as I stood under heavy

snowfall on a cemetery site outside the city watching

Yury’s casket being lowered into the ground alongside his

mother’s I changed my mind. I realized that producing a list

of his many accomplishments, which were self-obvious

and well-known, was not what I really wanted. I felt that

I had to tell the world just how fair, kind and loyal he was.

To me, Yury’s passing is absolutely personal tragedy. If not

for him, so many things in my professional and private life

could never have happened. I owe Yury an immeasurable

debt of gratitude, so does everybody at Olvex. This acutely

intelligent and generous man, who came from a small

town in Russia’s north-west, profoundly affected the lives

of everyone in the company he set up on both professional

and personal level. He was as much the heart as the brains

of our enterprise. For over 16 years that Yury was at the

helm, the staff of Olvex changed little. People just knew that

it would impossible to find a better employment within our

industry in Russia. He was true friend to us, a friend we all

could count on at any time and in any situation. He never

ever let us down. He never defaulted on a single promise. And

he never complained about anything, although his burden

of responsibility was a thousand times heavier than ours.

With his passing, the entire era came to an end. Life is not

going to be the same for us from now on. We all know that.

And what we also know is that we must carry on, because

we are now under moral obligation to complete his mission

and fulfill his dreams for him. This is how we can repay the

enormous debt of gratitude we owe Yury Mokin.

With love and gratitude,

Andrei Bushmarin, Olvex / PDi

European Demolition association Spring Conference 2010An interesting market for the demolition industry, easy access and good hotel facilities were the main criteria for selecting the Polish city of Warsaw as the venue for the EDA General Assembly and Spring Conference 2010.

Both the interest of European demolition companies’ and manu-facturers have been taken into account when choosing Warsaw as a venue for EDA Spring Conference 2010. Despite the challenging economic situation across Europe, “new” EU member states still benefit from EU funding for the development of their infrastructure and other projects of a public nature. Companies from countries such as Spain, who are used to dealing with EU-funded construc-tion projects, are already very active in the Polish market. Poland also functions as a bridge for contractors to other East European markets still outside the EU, where external construction/ demolition know-how is demanded.

As EDA President Mr Yves Canessa pointed out in the last Board Meeting in Amsterdam, “One of the EDA’s main challenges at the moment is to attract the new generation in the demolition industry to our conferences. It is not sufficient to organise events where we gather to meet old friends in the field and to do some tourism. The new generation is increasingly demanding higher-level technical presentations than the previous one. We have had young participants in both Nice and Istanbul from countries such as Switzerland and Denmark who have been quite impressed by the high level of the presentations. That is the way to attract new professionals to the EDA,” Mr Canessa added. In order to assure the highest technical level of the presentations in the Warsaw Conference, Board members, National Association and EDA IC members have been invited to submit their proposals to the EDA Secretariat. More info about the seminars in a coming issue of PDi.

In connection to the 2010 Conference a Gala Dinner with spon-sors and a farewell dinner for President Canessa will be held. The EDA’s 2010 General Assembly will see the end of Mr Yves Canessa’s tenure of office as President and the start of a new “Italian” era with Mr Giuseppe Panseri as the incoming President for the three years to come. A good farewell/ welcome dinner is to be expected on Saturday 29th of May.
