Back in May 2006, HHOAfrica became ISO 9001 compliant, so as acompany we have had 3 years of having a company wide (alloffices) with a quality management system in place and working.This period gives us a useful perspective to reflect on how our QMSsystem has matured and some of the benefits that have and arebeing realised:
M
Better client service and design deliverables.
Ability to manage more effectively large and complexinfrastructure projects.
Improved risk management.
Made us more competitive.
Financial benefits : getting it right first time (well some of thetime!!)

DECEMBER 2009
The SABS recently undertook their recertification audit of thecompany and I am pleased to report that our quality managementsystem (QMS) has been recertified for the next three years to June2012 – subject to the normal regular surveillance audits.
My thanks to all the Directors and Staff for making improved qualityin the company a continuous priority. As we are aware each one ofus has to uphold our quality standards – we are as strong as ourweakest link. Special acknowledgement however, must go to LesThomson (Director with special responsibility for QMS in thecompany), Graham Demmer (QMS Manager) and Nadia Lipsitz(QMS Admin.) for driving our quality management system and itscontinual improvement.
As we look back over 2009, I am pleased to report that it has been agood and productive year for HHO Africa. Many of our high profileprojects have moved from the design to the construction phase, likeGautrain, Koeberg Interchange, IRT Busway and CTIA airsideexpansions. Thank you for making this a successful year for thecompany.
And so what does 2010 hold for HHO Africa? We cannot pretendthe world economic crisis will not affect us – it will. However, thehighlight of next year will obviously be the hosting of the FIFASoccerWorld Cup, which I think will showcase brilliantly the capability of theSA construction industry and the event itself will provide a strongeconomic boost to our economy. That Bafana Bafana will gobeyond the first round? Miracles do happen! Central governmenthave committed and budgeted to spend in excess of R700 billion forthe provision of new and upgraded infrastructure, over the nextthree financial years, which is good news. This spend together withthe anticipated recovery of private sector lead developments shouldenable HHOAfrica to continue “innovating infrastructure for life”.
On behalf of the Directors of HHO Africa may we wish you and yourfamily peace and much joy over the Christmas season andthroughout the coming year. Enjoy your well earned break andcome back ready to meet the new challenges of a new year.

ZITHULELE SCHOOLESSAGE FROM THEANAGING DIRECTOR
HHO Africa's Mthatha office were
appointed by the Eastern Cape
Department of Education and the
Vodacom Foundation to undertake the
civil and structural engineering
components of Zithulele School. The
school is located on the outskirts of
M t h a t h a a n d i s d e s i g n e d t o
accommodate over 300 learners.
It is good to report that the contractor
Sizisa Ukhayo's, quality of work was
good and the contract was completed on
time! Our professional fee account has
also been paid!! A double plus. The
school was officially opened by the
National Minister of Education, Ms.
Angie Motshekga on 22 September
2009.

The Dinaledi
Educational
Programme
by Jeremy Clampett
Roger Crook, CEO of HHO Africa, talkswith Mr Geoff Figaji, Chief CurriculumAdviser in the Western Cape Dept ofEducation at the launch of the 2010Dinaledi Educat ional Coachingprogramme
A group of Science & Maths educatorsfrom schools in Crossroads and Delftwho will experience coaching in 2010 aspart of the Dinaledi EducationalCoaching programme pose with MrDonald Grant, MEC for Education at thelaunch of the 2010 programme recently
Dinaledi Educational Coaching is aSection 21 company which workshand-in-hand with the Department ofEducation, with trained and qualifiedcoaches with private sector funding indifficult schools in difficult areas. Theemphasis is on coaching educatorswho teach maths and science.
HHO Africa gave seed funding twoyears ago which was used to recruitand orient the team of coaches. Twoschools – in Elsies River andBonteheuwel – were selected for thepilot programme. The year-longintervention provided weekly coachingfor the first six months, then monthlycoaching for the following six months tothe principal, the deputy principal andthe Maths and Science teachers.
The programme was assessedindependently by the Cape Universityof Technology and reported positivechange in the following areas:personal growth, goal-setting; learnersmore self-directed; improved academicresults; positive mind-set; new ways ofthinking; accountability and overallenhanced performance.
In 2010 four schools in Delft andCrossroads will benefit from theprogramme, forty educators in all whowork in some of the most difficult andchallenged areas of Cape Town.HHO's financial contribution will beused to select and train the coachesand to provide materials used in theprogramme.
At a recent function, hosted by DinalediEducational Coaching at which DonaldGrant, MEC for Education, was theguest speaker, Roger Crook, CEO ofHHO Africa was invited and recognizedas one of the coaching programme'skey financial partners, together with theDG Murray Trust and the AngloChairman's Fund.
Over recent years, coaching hasachieved a proven record of results inthe business arena. Companies whichinvest in coaching usually find a six-foldincrease on their investment in terms ofemployee confidence, businesspurpose and profitability.
The Dinaledi Educational Programmewas launched with the intention ofachieving the same results in theeducational area, particularly in ourmost impoverished and difficultcommunities.

In previous newsletters you have read about the Integrated
Rapid Transit (IRT) System that is being rolled out in Cape
Town, predominantly along the corridor between the Cape
Town CBD and Atlantis. HHO is the lead consultant for this
Atlantis Corridor section of Phase 1Aof the IRT.
At present we have seven civil contracts and one building
contract on the go. The seven civil contracts are busy
constructing the busway lanes and station substructures
between the Civic Centre and Bayside Shopping Centre. The
building contract is following the civil contracts and
constructing the station superstructures. The civil contracts
and the majority of the building contract will be completed by
May 2010, just in time for kick off of the Soccer World Cup.
Based on the City's past experience of the difficulty of
enforcing bus lanes and BMT (bus minibus taxi lanes), it was
decided that self enforcing strategies be incorporated into
future bus lane construction. You need only look at the bus
lanes in London and other major cities of the world were
dedicated bus infrastructure has a different colour i.e. in
London the bus lanes are red. This communicates to the
general public that these lanes are for the exclusive use of the
designated vehicles namely, buses. The colouring of the bus
lanes alone will not carry the day, and to this end electronic
enforcement and physical measures will be used to deter
illegal usage of the lanes by someone in a hurry!
The majority of the bus lanes being constructed as part of the
IRT project are concrete (continuously reinforced concrete to
be precise). The concrete busways have been designed to
provide 30 years of maintenance free IRT operation - just
imagine trying to maintain or reconstruct a bus lane with
buses scheduled every 5 minutes!
To get the concrete red, a small percentage of red oxide has
been added to the concrete. In intersection areas, where it is
desirable to discourage traffic from blocking bus paths
through the intersection, and where concrete cannot be
utilised, a high friction surfacing will be applied to the asphalt
surface to get the desired red colour.
So, what is black and white and read all over - well I know it is a
newspaper, but it could also be theAtlantis corridor IRT route!
The Upper Culunca Regional Water Supply Scheme is located in the
Eastern Cape, to the east of the town of Qumbu and falls within the OR
Tambo District Municipality.
The scheme comprises an offtake from the Cengane Stream, a water
treatment works with a capacity of 2,5 Ml/day, and a distribution system of
pipelines and reservoirs which distributes potable water to 48 rural
villages. Presently the water supply is “run of river”, no storage is provided
other than short term storage within the service reservoirs. In order to
comply with DWAE's approval requirements, it is necessary to provide a
future storage capacity of 300 000 cubic metres.
Several dam sites on the Cengane Stream were considered before
choosing the current one. This site lies within an extensive dolerite area
and comprises an open valley with gently sloping sides (photo 1). The
preliminary investigations started five years ago. Photo 1View along centerline of proposed dam
Note treatment works in left distance

C DENGANE AM
The dam will consist of an earthfill embankment, 17 metres in height A
bywash channel spillway will be located on the left flank of the valley. This
spillway will comprise of a 20 metre wide lined section to accommodate
the 1 in 100 year design flood of approximately 120 cumecs plus a 40
metre wide unlined emergency spillway for the regional maximum flood of
just over 400 cumecs. The catchment area for the site is about 18 square
kilometers. The dam classifies as Category 2 in terms of dam safety
legislation.
A reinforced concrete outlet shaft will house a dual level intake system
and the control valves. A 38 metre span steel lattice structure footbridge
will provide access to the outlet shaft.
Although not a particularly large dam, the design has presented some interesting challenges. The size of the design and
maximum floods, relatively low wall height, the slope of the valley sides and the erosive nature of the completely weathered
dolerite make the spillway very expensive relative to the cost of the dam. Several alternative spillway configurations and
various linings have been considered in an attempt to optimize the spillway design.
Another challenge is the open jointed and highly pervious dolerite rock which occurs on the left flank of the wall (photo 2). This
will require careful excavation and cleaning during construction, followed by surface grouting and deep curtain grouting to
ensure a watertight structure.
The design of the dam is being carried out by the Geotechnical Division of the Cape Town Office, with input from Bob Blyth.
Planned completion of the design is early 2010.Application will then be made to DWAE for approval to construct the dam.
Construction is planned to commence in mid 2010. The estimated construction cost of the dam, including VAT and
Contingencies, is R20 000 000.

Koeberg Interchange, one of
our flagship contracts with a
total investment value of
R 7 5 0 m , i s p r o g r e s s i n g
incredibly well, thanks to the
team effort of contractors
making up the Paarden Eiland
Joint Venture formed by Group
Five and Power Construction
and our resident engineering
team headed by Leon Bester
and assisted by HHO staff
Gavin Pike, Andrew Rowan,
Safiyyah Aboo and James
Hendricks. They have all been
putting in long hours including
night and weekend work to
keep this prestige project on
schedule.
Delivery of Ramp A (3rd level
ramp providing free flow access
from N1 to M5 south bound) is
scheduled to be on time and
open to traffic before June 2010
and Ramp B (3rd level
providing free flow between M5
and N1 Northbound) is ahead
of its scheduled opening date of
October 2011.
The contracting team have
intelligently invested time and
effort in pioneering the use of as
many precast elements as
possible, having developed
sophisticated transporting and
launch techniques for the
enormous u beams being
placed at a rate of up to 5 per
night, as well as a durable
linkage system allowing them
to precast and structurally
attach the majority of the nearly
3 km of balustrading, ensuring
a superior alignment and finish.
The quality of a bridge is often
judged on the look of the
balustrade and if the first few
hundred metres are anything to
judge by it will be superb!

The adjacent contract for the upgrading of is advancing very well too
and will be complete in time for the World Cup in 2010. The contracting consortium of
Martin and East and Exeo Khokela are progressing well on this R150m contract.
Attendance at site meetings by Anton Nell of the PGWC and Dave Buerger of the City of
Cape Town has been invaluable in ensuring that hitches (technical or procedural) are
quickly resolved. They certainly both appreciate that engineering has enough natural
challenges and have helped in minimising the man made ones!
Table Bay Boulevard
DECEMBER 2009
The sheer size of the 70m single span box deck over the 8 rail
tracks can be seen in relation to the men standing inside the box.
Cables have been threaded through the webs of the first section
which is due for casting shortly. Enormous girders support the
soffit of the deck, an engineering feat in its own right.
The typical heavy daily flow of traffic which has been well &
virtually faultlessly deviated through the works.
A new footbridge will be brought into use shortly to replace the
old structure which has substandard height clearance & will also
not cope with the future volume of pedestrians crossing from the
rail station & the IRT stop to Paarden Eiland. The timing of the
commissioning of this bridge & the demolition of the old one has
to fit in with Soccer World Cup draw in Cape Town in early
December & Leon is keeping all parties informed & on their toes
to ensure a smooth transition.
The nearly 40m long precast u beams forming spans 12 & 13
were launched recently. Because of the length of the spans a
second stage prestressing has to be applied once the top deck
has been cast. Careful calculations ensure that the effect of
prestress hogging & elastic deformation due to dead load of the
added deck result in a level deck- seemingly obvious but
requiring careful monitoring to achieve this. Well done to site &
design staff who constantly liaise to make sure this happens.

Liberia is still recovering andemerging from nearly 20 years ofdevastating civil war. A combinationof the effects of the war, neglect andlooting has resulted in large swathesof infrastructure being derelict oro t h e r w i s e u n s e r v i c e a b l e ,particularly outside the capital,Monrovia. Nowadays, whi ls toutwardly things are calm the peaceis kept by 15,000 UN troops who arevery much in evidence at all strategiclocations.
Liberia has a paved road network,including city streets in Monrovia, ofless than 500 kilometres. The rest ofthe network, such as it is, is made upof laterite soil roads. Many of thecountry's roads were destroyed or, atbest, neglected during the civil war,and, every year, heavy rains (up to4000 mm of rain falls annually)damage them further. The poorstate of the road network leavesmany routes impassable and makesmany areas inaccessible for longperiods of each year - a situationexacerbated by the almost non-existent maintenance capacity of theroad authorities.
The photograph below shows atypical MAIN road during the rainyseason.

This is where the concept ofDevelopment Corridors comes intoplay. A Development Corridor isanchored at either end by a majordevelopment (in this case an iron oremine and a port). Bidders for miningconcessions are obliged to not onlyprovide the infrastructure that theythemselves require but to “overdimension” their infrastructurerequirements. For example, to allowthird party access to their rail linksand ports. In this way, other sectorscan “piggy back” on the miningconcessions and consequently canthemselves develop and bestrengthened.
HHO Africa were appointed by IBIInternational, an American companyworking with USAID to identifypotential Development Corridors inLiberia, to provide an infrastructureexpert to join their multi disciplinaryteam in Monrovia. The team, whichalso included mining, forestry andagriculture experts, was tasked withcarrying out a study to identifypotential Development Corridorsand determine ways to maximizetheir economic impact.
HHO Africa's input focused oni d e n t i f y i n g a n d p r i o r i t i z i n ginfrastructure and transport links thatwill have the maximum impact onst rengthening the proposeddevelopment corridors, promotinginternal, cross border and regionaltrade and facilitating generaleconomic and social upliftment.
One of the recommendations is thatall road rehabilitation measuresshould be based on the provision ofproperly engineered all weatherroads with appropriate horizontaland vertical geometry and withadequate drainage systems. Thusbridges and drainage structuresshould be designed to provide fullaccess and transit throughout theyear. This implies that the paving ofall major roads in the network shouldbe considered a priority.
The initial report will be submitted inDecember 2009 and at the momentthat is where HHO Africa's input willend. It is hoped however, that wecan become involved in subsequentphases of the project, subject tofunding of such phases by USAID.
ASSESSMENT OFTRANSPORT
INFRASTRUCTURE
LIBERIALIBERIA
Prior to the civil war the Mount Coffeehydroelectric plant close to Monroviahad a generating capacity of 64 MWand formed the backbone of theLiberian electricity supply grid. Most ofthe major towns in Liberia also haddiesel generating plants. However,both the Mount Coffee plant and thediesel generators were looted anddestroyed during the civil war. There isconsequently now no public powergeneration in Liberia other than by newdiesel generators located at sub-s ta t ions at severa l locat ionsthroughout Monrovia. These areconnected to the partly refurbishedmedium voltage system for distributionto selected areas throughout the city.
All rail links were also put out of actionduring the civil war as the lines weredug up and sold for scrap by thewarring factions.
The situation is therefore dire and,bearing in mind that the Government ofLiberia's TOTALannual budget is someUS$250 million, the majority of whichgoes to pay the salaries of civilservants, there is little chance of anymajor improvements soon, even withthe assistance of international donorsand agencies.
What is required is an impetus to kicks t a r t a n d s u s t a i n e c o n o m i cdevelopment and the provision ofinfrastructure.
Liberia has a possible trump card toplay in this regard as it is endowed withvast mineral resources, mostly in theform of iron ore, and huge agriculturaland forestry potential. If thesepotentials could be unlocked in asustainable way, then Liberia has achance to emerge from its current sorrystate.

EASTERN CAPE PRISONS UPGRADE
HHO Africa Mthatha office was
appo in ted by the Na t i ona l
Department of Public Works in 2008
to provide the civil and structural
engineering services for their Repair
and Maintenance Programme
(RAMP) projects at three Eastern
Cape Prisons, these being Lady
Frere, Dordrecht and Cofimvaba, all
three of which are relatively small.
The RAMP process commences
with the preparation of a Status Quo
Report from which the bill of
quantities and tender documents are
prepared. The contracts awarded
are structured to provide a six month
repair phase followed by a further 30
months maintenance phase i.e. total
contract period of 3 years.

Building Structural which includes painting, repair of structural defects,
repair of flooring and even the replacement of panes of glass and repair
of broken locker doors;
Building Wet Services which is essentially plumbing and sanitary ware:
Electrical;
Mechanical; and
Civil which includes driveways and parking areas, bulk water supply,
sewerage, drains etc.
The work is grouped into five different activities being:
The preparation of the Status Quo Report involves a
comprehensive survey of the whole prison facility noting all
and every item requiring repair or replacement. (This
includes electrical/mechanical elements but these are
managed by electrical/mechanical engineers.)
The maintenance phase is intended to keep the facility in
the required condition and operating effectively over the
contract period. It is required of the contractor that he
responds to “call outs”, routed via a call-centre, to effect
whatever repairs that may become necessary within a
prescribed time-frame for 3 categories of calls, depending
on the urgency of the repairs. On the “lighter” side of things
one of the contractors has had to send a technician 160km
to change a light bulb.
The work involved is not high-tech but the challenge lies in
the enormous variety of bill items. The contract
documentation is based on the SABS 1200 standards and
the General Conditions of Contract and all items are thus
remeasureable, making for easier management. The
Department has over the years developed a
comprehensive and extensive set of specifications,
covering all aspects of the work, which leads to rather bulky
documents but the requirements are well defined. All of
these factors making the management of these projects a
major administrative exercise rather than an exercise in
engineering.
Our involvement has been very interesting, if only for the
fact that it is different to our usual work, but also to
experience, for as short a time as possible, being “inside”!

on the Wi ld Coas t , s i t ua ted
approximately 100 km east of Mthatha.
The existing roads are in a poor

30 years ago with little or no
maintenance. Over the past 15 years
the town's re-development as a tourist
attraction has been hampered by a lack

The labour intensive work has been very much alearning curve for all concerned and initiallyrideability and compaction proved to be thegreatest challenges. Regular training andmentoring are having a positive effect on thesechallenges and quality continues to improvedaily.
The method of construction is some 60% moreexpensive on layer works and 30% moreexpensive on surfacing, when compared with aconventional machine dominated contract.Overall, however, the additional cost is less than15%.
The Gansbaai LIC Project is currently 50% complete and is running approximately 1 month behind schedule due to weatherdelays. Also conditions on site have been unfavourable for labour intensive work due to gale force winds and excessive rain.Despite this, the contract is making good overall progress.

Technical considerations during the
design were:
Existing grade line could not be
altered
Low lying level of existing streets
generally below 3m above MSL
Tidal influence - constant wetting
and drying cycle of insitu materials
Lack of suitable materials in close
proximity to the town centre
Heavy rainfall area giving rise to
stormwater drainage problems
Location of existing services within
the road reserve
Construction is expected to commence
in January 2010.

A decision was made to use concrete
brick pavers in the CBD as these are
easier to maintain and increase the
labour component during construction.
80mm pavers are to be used for the
streets with 60mm pavers for the
sidewalks. The road cross section is
7m wide with 1.5m sidewalks and
parallel parking on both sides of the
road in the business areas.

In September this year,HHO Africa was againinvolved in the Desmond TutuBuilding on Faith (DTBOF)Habitat for Humanity Build.
A large financial contributionwas made by HHO Africa andmany of the staff memberswere involved to build a housefor No-Amen ThembekaManka in Mfuleni.
Over two days, teams of 9 and11 volunteers respectively,gave themselves to hardlabour, had a lot of fun andgained new experiences.
Unfortunately not everybodycan be mentioned hereindividually but HHO thanksall the volunteers for makingthe days as special, enjoyableand unique as they were.
Giving back to society seeminglyentails more than carrying bricks orfitting roofs. Lihan was entertainingkids by carting them up and downthe street.

Fortunately after every hard climb there is a descent and this is whereyou have to hold on to your handle bars and be brave reaching speeds of more than 70km/h, notthe time to show that you are capable of riding with no hands!

As we drove into the SANRAL Imbizo venue in Paarl early on Friday 13th November, wethought “our luck has really run out” as the first drops of rain fell. This year's Imbizo themewas the "Recession & How to Beat it"!
HHO Africa was to pull off some major upsets and demonstrate that we live by ourcompany's mantra and war cry:
We practiced; got it right and belted it out like thevery best. Our ladies put their best foot forward with an exceptional 3 plates of food from thelimited selection of groceries for the cooking competition. Not forgetting the great braai weheld.
Sporting wise, we showed that a diverse group is a strong group, beating all the 'strong'contenders to reach the semi – finals of the tug of war. Our soccer was 'on point' as wereached the final and were runners up for the penalty shoot-out. The obstacle course wasjust that to the now tired out 12 persons (3 ladies / 9 men) squad…an obstacle. We didhowever participate!
The day was long, it was tiring but most of all it was enjoyable. We really did put our bestfoot/feet forward and hope that we made the rest of the company proud…. to beHHOAFRICA…. right back at ya!

All went well and I had a great race. The highlight was sharing moments on the ride with fellow riders after the race whileenjoying a well deserved cold beer. Hope to see some of you at next year's event.
