Our proposals for
Bessant Drive, Kew
With extensive involvement from the community, our designs
have been developed to maximise the amount of air and light
throughout the project. The new buildings will be set amongst
extensive green surroundings, with a landscaped courtyard at
the centre for community use, a new gateway entrance from
Bessant Drive will be provided along with a wider redesigned
boundary to Strand Drive, creating an open, green street,
opposite the existing river frontage buildings.

Key Facts
Noise, dust and vibration monitors are already in place at the
Bessant Drive site and will remain in place throughout groundworks
and frame construction.
Works on site restricted to 8am-6pm, Monday to Friday,
and 8am-1pm on Saturdays.
The monitors are located closer to the works than is recommended
by the EHO – so our measures to restrict noise, dust and vibration
are more stringent.
Continuous flight auger (CFA) and hydraulic pressed-in sheet piling
will be used as opposed to a driven system.
Dust to be suppressed by covering skips and loads. Water
suppressants to be used during site activities.
Piling and excavation will take place in the second half of 2015.

Steps we are taking
to limit disruption
Noise, dust and vibration monitoring
We contacted the Environmental Health Officer (EHO) and requested he attend
site to discuss the options available to the development to help reduce
the impact of noise, dust and vibration on our neighbours. Further to these
discussions we decided to provide three types of monitors. Instead of placing
them at our neighbours boundaries we have positioned them within the site
closer to the source. By doing this, we are placing more stringent measures
on our site contractors than the recommendations of the EHO.
In the unlikely event that monitors are triggered at any time, we will receive
an alert. We will then contact the site contractor requesting confirmation of what
set off the alert and ask that they change the way in which they are working to
alleviate the problem.
Dust will be mitigated by the following measures:
• Covering skips when not in use
• All loads leaving site to be covered
• Water dust suppressant to be used during site activities
• Cutting equipment to use water suppressant
Noise and vibration will be mitigated by the following measures:
• Works on site will not be carried out outside the hours 8am–6pm,
Monday to Friday (excluding bank holidays)
• Works on site will not be carried out outside the hours 8am–1pm on Saturdays
and this will be avoided
where possible.
• Hand-held and portable equipment will be electrically powered
where practicable
• Activities producing significant noise levels will be carried out at times
which are less likely to cause disturbance where possible
• Utilising alternative piling methods
Piling
The standard most cost-effective form of piling within our industry is driven,
however this form of construction can create elevated levels of noise,
dust, and vibration. Given the concern within the local community over noise,
dust and vibration we have changed our method for carrying out these works.
Instead we shall now be piling using Continuous Flight Auger (CFA) piling and
hydraulic pressed-in sheet piling methods.
The pressed-in sheet piling method will be undertaken first. This piling method
involves a rig hydraulically pressing steel sheets into the ground, with water jetting
used to get past hard spots to reduce vibration and noise. See below pictures of
the two methods of construction.
A capping beam will follow the sheet piles. During this time bulk excavation
will start, programmed for circa 30-40 loads a day to be removed from site.
The CFA piling method will follow this, and will involve a rig drilling into
the ground and pumping concrete into the ground as the drill retracts.
The piling and excavation process is scheduled to take place throughout the
second half of 2015. Movement of heavy equipment on and off site will be
undertaken under police escort. You will be notified of these movements by
letter in advance.
Key Facts
The rate of surface water run-off from the old Inland Revenue site
was 96.4 litres per second for the 1 in 1 year storm.
Through use of a storage tank and permeable paving, the actual
run-off rate for the new development will be only 5 litres
per second.
We are required to halve this to 48.2 litres per second by the
London Plan.
The storage capacity for water run-off is 448,000 litres of water.

Preliminary design for SUDS
In its former use as an Inland Revenue
building, 60% of the Bessant Drive site was
impermeable to surface water run-off.
The rate of surface water discharge to the
local drainage network was calculated as
follows for the former Inland Revenue site:
• 1 in 1 year storm – 96.4 litres per second (l/s)
• 1 in 30 year storm – 227.6 l/s
• 1 in 100 year storm – 288.8 l/s
The London Plan asks that our development
reduces the rate of surface water discharge
to 50% of the rate of the site’s previous use
for the 1 in 1 year storm event. This works
out to 48.2 litres per second.
The area highlighted blue in the image
shown is the storage area on our podium
which will be created for surface water
run-off. This area will be covered by
permeable paving allowing the water from
our roofs and landing on the podium to
absorb through to these storage tanks.
The surface water from the storage tanks
then discharges to the local drainage
network at a rate of 5 litres per second. By building to these proposals we are exceeding
the requirements of the London Plan by 43.2 litres per second, significantly reducing the
impact on the surrounding area from the previous site use.

Construction management plan
Construction traffic will enter from
Bessant Drive and the A205. All supplies
and contractors will be briefed with the
construction logistics plan prior to arriving
on site.
The plan depicts no access to Strand
Drive or beyond the new location of
the gates to The National Archives
once relocated.
A jet wash will be operated on site to
reduce the amount of mud dropped on
the public highways, along with a road
sweeper during the groundworks and
frame erection on Bessant Drive.
Waste from site will be segregated and
recycled as appropriate in line with our
site waste management plan.

Transport package
We have prepared a package of transport proposals as part of our scheme
which takes into account the feedback we received from the local community
during previous public consultations.
This includes:
• Car parking provided to meet maximum standard plus visitor parking.
• A drop-off facility for the proposed GP surgery alongside parking within
the basement for appointments.
• Provision of a dedicated space for a car club vehicle.
• Moving the keep clear sign on the Bessant Drive/Retail Park Access T-junction.
This will minimise ‘blocking back’ occurring, making it easier for vehicles to exit
Bessant Drive (from Strand Drive) onto the first section of Bessant Drive, which
connects to Mortlake Road.
• Extension of the northbound right turn lane towards the Mortlake Road/
Bessant Drive signal junction. The right turn lane back from the signal junction
will be extended from 50m to 150m. The purpose of the longer lane is to allow
traffic to exit out of any queuing traffic along Mortlake Road at an earlier point,
to turn right into West Park Avenue and Bessant Drive. This will also benefit
bus service R68 which can be delayed by traffic travelling northbound along
Mortlake Road.
• A Travel Plan to survey, monitor and encourage residents and staff at the
GP surgery (if staff levels are greater than 20) to travel by more sustainable
means, by the implementation of measures such as: provision of information
on travel choices, events to raise awareness of the choice and health benefits,
car clubs, etc.
• Agreed developer contributions to the London Borough of Richmond upon
Thames for sustainable access improvements.
