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





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.





4.0 PAVEMENT PILING WORKS

4.1 The installation of piles will require a larger area to be allocated to allow for the

installation of piles below the pavement to create the retaining wall between the

new basement and the street. It will be necessary to temporarily widen the work

area to some 4-4.5m to allow for the piling rig to operate. These works will only

last 1-2 weeks. A system of traffic control by “Give and Take system” or by

“Priority signs” will be introduced for the duration of these works subject to

agreement form the council transport department. A minimum unobstructed

road width of some 3.4m will be retained at all times. We propose that a narrow

footpath be introduced adjacent to the hoarding for the duration of these works

to improve the safety of the pedestrians.

5.0 ENVIRONMENTAL ISSUES

5.1 By environmental issues we mean the potential for temporary and permanent

impacts on the local environment from the works.

5.2 Noise – the majority will come from the operation of mechanical plant,

particularly compressors, excavators, concrete pumps and hydraulic breakers.

Noise should be limited in accordance with the planning condition 8 which

clearly states the acceptable noise levels. Generally, all noisy operations must be

restricted to 9am to 5pm.

The majority of the basement works would be done by hand without the use of

heavy plant. It may be possible to perform some excavation using smalllightweight excavators, once the main underpinning works have been

completed. However, there will be some noise and disruption linked with

breaking out and removal of the existing structural elements (walls and floors).

The aim should be to perform these works quickly to minimise the duration of

these works.

5.3 Vibration – works which involve breaking out or drilling into existing hard

structures has the risk of transmitting vibration to adjacent buildings. Again, the

aim would be to minimize the duration of these works. The plant should be

supported onto adequate proprietary anti-vibration mounts to prevent the

transfer of vibrations.

5.4 Dust – a planning condition may require the damping down of dusty activities.

In addition, should the works be done in two phases, great care must be taken to

ensure that the dust is contained within the unit currently undergoing

construction.

5.5 Traffic – see other sections of this report.

5.6 Archaeology - The site is located in Belgravia and the construction of the

basement will involve the removal of shallow strata likely containingarchaeological material. Planning conditions may require archaeological

assessment of the site, although the site does not fall within any of the council’s





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





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





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.
