2.0 DESCRIPTION OF THE WORKS
2.1 The proposed works to the property include the formation of a new basement, as
well as the rebuilding of the entire house incl. new walls, partitions, floors and
the roof to replace the existing structure. As the building plot of the mews house
extends underneath the existing pavement, the proposed basement extends some
1.2m beyond the front elevation with a proposed rooflight set flush within the
pavement. A fairly standard construction method involving traditional
underpinning as well as piling will be used to form the new basement space.
Please see the attached reduced structural drawings included in Appendix 1.
2.2 The works on-site can divided into 9 distinct stages as indicated in the attached
sketch drawing 1101-589-TP2. The attached drawing also contains a detailed
description of the proposed works, as well as the proposed construction method.It should be noted that, it is likely that stage 3&4 would likely run in parallel
with stages 5-7.
2.3 A draft programme is also attached in Appendix B indicating the likely duration
of the construction works.
3.0 SITE ACCESS AND SET UP
3.1 The delivery/collection vehicles will generally enter and exit Pavilion Road
from Point Street and Sloane Street via Cadogan Gate.
3.2 It is proposed to provide temporary site hoarding some 2.4m away from the
front face of the house to provide a sufficiently sized safe working area. This
area would allow for the construction of a new basement projecting 1.2m away
from the house. It would protect the road users, as well as provide a physical
barrier to the adjacent properties. Adequate lighting will be provided to the
temporary hoarding. The skip would also be housed within this area, with a
conveyor installed to simplify the removal of spoil from underneath the house.
A larger skip has been proposed to minimise the amount of removals operations
and the amount of traffic generated, considering the amount of spoil and otherconstruction material that needs to be moved. Because of possible damage or
impact on the state of the carriageway, roll on roll off skips are not to be placed
on public highways. In addition, a percentage of the excavated material is likely
to be made ground, and may be contaminated. Such material must be adequately
disposed of.
3.3 Please note that an unobstructed roadway width of some 6.05m would remain as
indicated in the sketch drawing 1101-589-TP1. This should be sufficient to
allow for unobstructed two way operation in accordance with DFT “Safety at
street works and road works” which is attached in Appendix 3. Should this be
insufficient, we propose that a system of traffic control by “Give and Takesystem” or by “Priority signs” be introduced. Details also included in Appendix
Job Ref: 0908-459 – Construction Traffic Management Plan 116 Pavilion Road, London SW1X 0AX
(c) STS Structural Engineering Ltd 6 Status: Rev A
3. Assistance will be provided to ensure safe and efficient passage for large
vehicles (e.g. HGVs or Refuse collection).
3.4 The removal and replacement of skips will require the vehicle to be parked in
front or behind the temporary hoarding. Similar arrangement will be required
for concrete lorries as and when required. Space for vehicle parking shouldnormally be contained within the boundary of the construction site. Should this
not be possible, a written consent or permission from house Nos. 114 and 118
Pavilion Road to park concrete/skip removal lorry in front of their property must
be sought as this may have access or noise implication. Please see the attached
sketch drawing 1101-589-TP3. A banksman will be in attendance for the
duration of all loading and offloading operations. It is also his task to ensure that
any debris are swept from the road on completion of these activities.
3.5 The amount of construction traffic and the level of disturbance to the public will
vary with each stage of the works. Therefore, we anticipate a frequent concrete
deliveries and a number of skip removals during the excavation works (stages4&5), with a number of specialist deliveries vehicles as the works progress
towards the finishing stages. However, as a general guidance, we provide the
following numbers:
Who Purpose Frequency Approximate Vehicle
Duration Type
DC General Building General Delivery/Collection Daily 20-30 minutes 2
DC General Building Project Management Daily 20-30 minutes 1
Skip Company Removal of Spoil Daily (1-2) 20-30 minutes 3
Concrete Company Concrete Delivery Daily 20-30 minutes 3Building Control Review of Works Twice a week 20-30 minutes 1
DC General Building Healh & Safety Weekly 20-30 minutes 1
Vehicle type: 1=car/small van, 2=Large van, 3=8 Wheel or Equivalent
Note that this does not include visits by the professional supervision, party wall surveyors and otherparties involved in the project, as well as other sub-contractors involved in the later stages of the works.
All site visitors and consultants in charge of the Project Management, H&S, Building Control, etc. are
not allowed to wait on the street for such reasons and should use local garages and pay&display car
parks; vehicles are only allowed to stop at the site to load/unload of goods/materials or actively engaged
on construction activity. N.B. Large vehicles (vehicle type 3) can only attend site between 10am and 4pm
to avoid residential disruption.
3.6 All deliveries and collection of site rubbish (and in particular skips and concrete
lorries) will be planned to take place outside both the morning and afternoonpeak hours, and will be limited between 10:00 and 16:00hrs. These will
normally be carried out on daily basis, but should not take longer than 20-30
minutes. A call up procedure shall be put into place to ensure that vehicle travel
times are staggered to prevent further congestion, and unnecessary parking and
waiting at Pavilion Road. The deliveries will be co-ordinated to prevent multiple
traffic movements during the same period and reduce congestion during the
busy hours.
3.7 Part of the premises within the house currently not being worked is to be
allocated for the use of the contractor to provide site office facilities, welfare
facilities incl. W.C. Changing rooms, showers, as well as for the temporarystorage of materials on-site and overnight storage of construction plant.
Job Ref: 0908-459 – Construction Traffic Management Plan 116 Pavilion Road, London SW1X 0AX
(c) STS Structural Engineering Ltd 8 Status: Rev A
designated safeguarded zones of special archaeological potential as indicated on
the RBKC plans.
5.7 Energy Use and CO2 Emissions - Great care must be taken in reducing the
impact of buildings on the environment. It is considered that 25% of CO2
emissions come from the construction industry including the emissionsassociated with manufacturing materials, transport, construction and demolition
of structures. Generally the excavation of basements requires moving large
quantities of material, and installation of concrete. These should be offset by
providing above standard insulation, and low energy lighting to the building to
reduce long term impact. To reduce the use of artificial lighting and mechanical
ventilation, two front light-wells are proposed to the basement. The contractor
should also consider using recycled materials (namely concrete) in the
construction of this basement.
5.7 Permanent Impact - No permanent negative impact is to be expected of this
development. The proposed basement will provide additional floor area withinthe footprint of the existing building in line with current development policies.
The proposed development does not involve any changes to the exterior of the
building, and as such would not have any negative impact on the street-scene.
6.0 HEALTH AND SAFETY ISSUES
6.1 The construction of basements is generally hazardous. A detailed health and
safety plan must be prepared by a competent contractor and approved by thelocal authority prior to the commencement of work. It must deal with the
following issues.
6.2 Access on site – Safe and adequate access must be provided to all parts of the
site, and site must be kept tidy. The site must be adequately horded to prevent
access (either accidental or deliberate). The proposed conveyor must be
properly secured. The skips must be lit. When the work has stopped for a day,
the site must be secured, all ladders and access must be removed, the plant must
be immobilised, and all dangerous materials must be safely stored.
6.3 Adequate welfare facilities must be provided and kept well maintained andclean. A section of the existing building not currently being worked on is to be
allocated for welfare facilities at all stages of the works. Welfare facilities are to
include a W.C., site office, changing rooms, washing facilities, clothes storage,
etc.
6.4 All temporary works must be carefully designed, constructed and inspected to
ensure the stability of the structure during all stages of the construction.
6.5 Excavations - Serious injury or even fatal injury could occur if a worker gets
trapped in inadequately supported excavation as well as from falling objects and
ingress of water/gases into excavation. Adequate safety procedures must be in
place at all times. When the excavated material is likely to be sands, sheeting
must be provided and adequately propped. Barriers must be provided at the edge
Job Ref: 0908-459 – Construction Traffic Management Plan 116 Pavilion Road, London SW1X 0AX
(c) STS Structural Engineering Ltd 9 Status: Rev A
of the excavation to prevent people falling in, and ladders provided for access.
Materials, spoil and plant must be stored away from the edge of the excavation
to reduce the chance of a collapse.
6.6 A detailed method statement and sequence of works must be adhered to in
connection with the proposed underpinning works. All specified temporaryhorizontal and vertical propping must be provided as per the design. In addition,
adequate emergency procedures need to be developed and put in place.
6.7 There is a risk associated with working in the vicinity of underground services
to include damage to existing services, electrocution, gas, explosion/fire, release
of sewer gases and contamination of water supplies. A utilities search of the
area must be performed, and all public utilities appear to run under the
pavement and under the street. However, private services must be identified and
adequately marked, isolated and secured during the construction.
6.8 Standard procedures should be utilized for safe loading and unloading of goodsand staff must be adequately trained for safe manual handling of materials and
goods. In addition, staff should be trained to safely use and maintain tools,
hoists and other machinery. Dangerous parts must guarded, eg gears, chain
drives, projecting engine shafts. The proposed conveyor must be adequately
protected at all times. Adequate over-night storage must be provided to prevent
theft and damage.
6.9 Loading and unloading goods and traffic management – There is a risk to both
the workers and general public/pedestrians associated with loading and
unloading goods. An exclusion zone must be set-up and a method of
loading/unloading must be prepared. Adequate safety footwear and gloves must
be utilized. Traffic management measures have been addressed in the previous
chapters.
6.10 Emissions and Hazardous substances – The site must be kept well ventilated to
prevent the build-up of hazardous gasses. Provide a high capacity ventilation
system with backup. Only electrical plant should be utilised on-site, and no
internal combustion engines should be used if at all possible. Finally, the soil
should be inspected for the presence of radon, with measures taken to mitigate
the risk if radon has been detected. Other hazardous substances such as asbestos,
lead, solvents, paints, cement and silica dust must be identified at an early stage,and these should be adequately cared for and used in a safe manner.
6.11 Fire – To prevent burns or smoke inhalation injuries, adequate procedures must
be put into place. Reduce the quantity of flammable materials, liquids and gases
kept on site to a minimum, and store these properly. Flammable gas cylinders
must be properly maintained, and always be returned to a ventilated store at the
end of the shift and valves checked. Smoking and other ignition sources should
be banned in areas where gases or flammable liquids are stored or used. Suitable
fire extinguishers and fire blankets must be easily accessible and properly
maintained.
6.12 Noise – some aspects of noise have already been dealt in the previous chapter.
In addition to protecting the neighbours from excessive noise, further measures
Job Ref: 0908-459 – Construction Traffic Management Plan 116 Pavilion Road, London SW1X 0AX
(c) STS Structural Engineering Ltd 10 Status: Rev A
are required to protect the workers on site. All sources of noise should be
identified and assessed. Workers using such plant should be trained and
provided with ear protection. Investigate measures of reducing the amount of
noise produced by existing plant, or consider replacing noisy plant.
6.14 A health and safety plan must describe the appropriate procedures foremergencies and for reporting accidents. All staff must be trained to know their
role in the event of emergency. First aid provisions should be good enough.
Suitable persons should be employed to work on site and must possess adequate
training and experience for the job, and all staff and subcontractors should
receive adequate health and safety training and be provided with the required
safety equipment.
6.15 The information in this chapter is based on the "The absolutely essential health
and safety toolkit for the smaller construction contractor"" published by HSE
7.0 DISCUSSION AND RECOMMENDATIONS
7.1 This Report is in Draft form and will be expanded following consultations with
the RBKC transport department.
7.2 The proposed construction works will involve the construction of a new
basement under the existing mews house and rebuilding of most of the existing
superstructure followed by general fitting out works.
7.3 The delivery/collection vehicles will generally enter and exit Pavilion Roadfrom Point Street and Sloane Street via Cadogan Gate. The anticipated number
and type of construction vehicles indicated in section 3.
7.4 The construction of the basement will require a section of the pavement/road,
some 2.4m wide to be temporarily hoarded to allow for the construction of the
projection part of the basement, as well as for the temporary skip storage,
deliveries, etc.
7.5 A larger section of the road will need to be taken possession of for a short
period of time (1-2 weeks) to allow for the installation of the pavement piles.
Adequate traffic management systems are to be put in place for the duration of the piling works.
7.6 All health and safety aspects listed in section 6 should be addressed. Working
hours and noise levels stated in the planning decision notice must be adhered to.

Traffic control
The need for traffic control Adequate width is required for two-way working. An unobstructed width of the road past the works must meet the
minimum shown in the following table, dependent on the type of traffic. Where possible, widths above the minimumshould be provided in order to give space to cyclists.
Where these widths cannot be met, shuttle working with traffic control must be introduced, and the unobstructed
width reduced to a maximum of 3.7 metres.
Where an unobstructed width of at least 6.75 metres for two-way traffic cannot be provided there may be problems
for HGVs and buses. In these circumstances, where a bus route exists, you must consult your supervisor who will
advise the public transport co-ordinator.
Normal traffic including buses and HGV Cars and light vehicles only
Two-way working 6.75 metres minimum 5.5 metres minimum
Shuttle working with traffic control 3.7 metres maximum
3.25 metres desirable minimum
