1 Introduction
The Code of Construction Practice Part (CoCP) A sets out general construction
principles and requirements that will be applied in the construction of the Victoria
Station Upgrade (VSU) Project. The CoCP Part B is a site specific document
detailing how specified items in Part A are to be applied for each element of the
works. Part B is not intended to be an exhaustive account of every element of the
VSU works and their mitigation as their development is not complete at the time of
writing and could not be covered adequately is such a limited document. Instead this
document is focussed upon those issues with the potential to cause impacts outside
of the worksites in order to inform stakeholders of the proposed approach and
mitigation. It is important to stress that VBN will follow the measures specified within
Part B in addition to those mitigation measures specified in the CoCP Part A. It is
therefore important to have due cognisance of both documents when reviewing the
works.
The intended forum for communicating a more detailed and timely account of the
works is the Community Liaison Group described in section 4 of the document with
the terms of reference published in Appendix 3. This is a regular forum throughout
the works which will facilitate a more informed discussion of the proposals once the
works have been defined.
A suggested content of the CoCP Part B is included in Appendix 1 of the CoCP Part
A. The rational for the inclusion or omission of these elements is described below:
Conditions imposed on planning permissions, and assurances given in relation to
planning and other consents
The process for discharge of the planning conditions is as follows:





1
VSU submits the required information to the local authority (City of
Westminster).
This information is then made publically available via the CoW website1.
Certain planning conditions, namely Condition 2 (Above Ground Structures)
and as agreed between VSU and CoW, will be presented to the CLG prior to
formal submission under the planning approval process.
Details regarding the planning conditions are not included within the CoCP
Part B due to them being publically available on the CoW website.
Details of the 3rd party agreements made between London Underground and
project stakeholders are also not included due to the confidential nature of
some of these agreements.

Site Environmental Management Plan (SEMP)
The Site Environmental Management Plan comprised within this CoCP Part B has
been compiled on the basis of eleven different sub-plans focussing on each
environmental aspect of the works. The environmental aspects addressed within this
SEMP / CoCP Part B include:





Noise and Vibration (Section 8)
Dust (Section 9)
Contaminated Land (Section11)
Water (Section 7)
Archaeology (Section 12)
Environmental aspects which are not considered to impact upon local stakeholders
(and therefore have not been addressed in detail within this SEMP / CoCP Part B)
include:
 Energy Management Plan
The Energy Management plan describes how energy will be managed throughout
the construction stage including the most significant aspects of energy consumption,
and how these will be controlled. Objectives and targets associated with energy use
are described in this document, as well as the means by which performance will be
monitored on an on-going basis throughout the project.
The strategy for conserving energy and using it appropriately on-site will follow the
following steps:
1.) Monitoring and measurement of energy use
2.) Assessment of energy use and identification of saving opportunities
3.) Development and implementation of control measures to manage different
energy consuming processes (including learning from other projects)
4.) On-going (day-to-day) management of relevant activities
5.) On-going monitoring of energy consumption against stated targets
A wide variation of construction types and methods will be in operation during the
project. Therefore specific consideration regarding the control measures for energy
conservation on-site needs to address the following:




Procedures for identifying - for different construction practices - where the use of
energy is unnecessary and to ensure action is implemented
Proper handling and operation of tools and other powered equipment
Efficient installation methods
Regular inspection of working practices, plant and equipment
Site inspections will include specific provisions for checking working practices, plant
and equipment to ensure energy is used as efficiently as possible and should reflect

Code of Construction Practice part B – Victoria Station Upgrade
Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011
the considerations above. However, a number of general procedures will apply to all
construction activities, and consideration should be given to the following measures:





All temporary supply will be shut down centrally at the close of the site at the end
of each day
Stand lights should be switched off (and removed) when construction activities
are not taking place in their vicinity
Ceiling mounted lights should be switched off when no construction activities are
occurring on the relevant storey
Tools should not be left on standby for more than a 15 minute period (i.e. if they
are to remain unused for more than 15 minutes)
On completion in a work area all electrically powered tools must be unplugged (if
not requiring charging) and not left on standby.
Construction Managers and Site Supervisors shall be responsible for ensuring that
energy considerations are included in daily and weekly site inspections and those
issues are reported to the Energy Manager.
Subcontractors‟ Site Managers will be responsible for ensuring that their office
facilities are managed in compliance with this procedure and that they communicate
clearly the objectives and scope of the Energy Improvement Programme to their staff
when it commences.
In addition all site and office staff will be made aware of targets and control
measures in team briefings, and the performance of the energy programme reviewed
in management meetings.

Green Travel Plan
The principal objective of the Green Travel Plan is to reduce, through a combination
of incentives and disincentives, the pollution generated by the construction workforce
of the project travelling to and from work. This shall be achieved by:



Supporting the use of more sustainable modes of transport including public
transport, cycling and walking by all staff;
Eliminating the use of the private motor car and dependency on single
occupancy vehicles; and
Reducing the number of vehicle trips to sites.
VBN‟s strategy to meet the identified targets will comprise of a mix of promoting
sustainable forms of travel and restricting less sustainable forms of travel. Key
measures will include:

a. Encourage cycling and walking to work







The VSU project will benefit from the introduction of the Barclays Cycle Hire
Scheme for London. Docking stations for this scheme in and around the site
at Victoria are highlighted on the map below as red dots. Information about
this scheme is being provided to staff and participation for central London
journeys is encouraged through the payment of a cycling allowance described
below
Secure cycle parking is to be provided once possession is taken of the sites.
This area shall be highlighted on the site layout plan once this has been
drafted. A copy will be attached to this plan. The number of spaces to be
provided shall be informed by the staff survey and an additional 10% provision
will be made to encourage further take up
VBN will offer all employees 20 pence per mile cycling allowance
VBN provides on site shower facilities at the VSU work site (in construction
phase)
VBN will promote the health and lifestyle benefits of walking and encouraging
staff to integrate walking into part of their journey during staff inductions
VBN will provide (or direct staff to) maps within common areas showing local
walking routes and estimated walking times
Guidance on how to use and where to find the Tfl Smarter Travel Units will be
displayed on site notice boards within the canteen and changing rooms. Maps
of the Cycle Superhighways and information on the Cycle Hire Scheme
(above) will also be displayed. Questionnaires will also seek suggestions from
staff on improved incentives
b. Encouraging use of public transport



During work inductions all staff will be encouraged to take public transport, or
consider cycling, where possible
Tube, train and bus maps will be held on site in communal areas and will be
distributed during staff inductions
VBN covers reasonable travel expenses for staff including travelling to and
from work
c. Reducing reliance on private cars

A „no car parking‟ policy has been implemented throughout the VSU project
d. Methods to reduce the need to travel



Broadband internet and e-mail facilities have been established at office
locations
Video-conferencing facilities will be made available at office locations
Asite electronic document management system is in operation

 Site Waste Management Plan
VINCI BAM Nuttall (VBN) utilise the Waste and Resources Action Programme
(WRAP) Site Waste Management Plan to control the movement of waste on the
project. This includes descriptions of:





Who is responsible for the waste
What type of wastes that are predicted to be generated
How these wastes will be managed
Which contractors will be used to ensure the waste is correctly recycled or
disposed of responsibly and legally
How the quantity of waste generated by the project will be measured.
Some of this information remains commercially sensitive and consequently is not
included within this document. Aspects of waste management that would potentially
impact upon local stakeholders is included in the section 9 (Contaminated Land).
Health and Safety Plan / File
The term Health and Safety Plan has been replaced by Construction Phase Plan
(CPP). The CPP describes how VBN will manage all Health and Safety aspects of
VSU. It will be used by the VSU team to ensure that the project is delivered safely
and that adequate risk control measures are identified and put in place at all times to
protect all parties from the effects of the works.
The CPP is supported by the Safety Management System which is compliant with
the Construction (Design & Management) Regulations 2007 (CDM07) and the
Contract Health and Safety Requirements. This management system is based on the
BAM Nuttall company requirements whilst complying and considering current
statutory regulations, guidance notes and London Underground Ltd Contract
(QUENSH 13) Conditions and current industry best practice.
The CPP can be inspected at the VBN offices with reasonable notice. Extracts from
the project risk register that relate to public interface and interaction are to be
provided at regular CLG meetings by VSU.
Consents obtained / co-ordinated by the main contractor under Section 61 of the
Control of Pollution Act
All Section 61 consents will be communicated to the CLG prior to submission to
Westminster as described in Section 7.
A Mitigation Commitment Register
VBN will monitor all commitments, including those specifically relating to mitigation,
as part of an overall assurance procedure for LU. Details of mitigations proposed
during construction are described in the relevant sections of this document and
further detail will be provided in S61 Applications.
Complaints Procedure
A copy of this is presented in Appendix 2.

VBN subcontractors will be briefed on the contents of the environmental plans and
Code of Construction Practice (Parts A and B) and will be required to sign up to their
responsibilities at tender stage and during pre-start meetings. Regular co-ordination
meetings between VBN and sub-contractors will follow based on a risk assessment
of their works (i.e. to brief conditions and requirements of Section 61 consents,
discharge consents, dust suppression requirements etc.). The most intrusive
activities such as jet grouting will be monitored closely. A meeting will be held at
least every 4 weeks with the subcontractor. Less intrusive activities such as survey
works will be reviewed at co-ordination meetings as required.
All VBN staff, operatives and sub-contractors working on the VSU project will be
required to undergo a comprehensive site induction, detailing the processes and
procedures that will be implemented during the course of the works. The induction
will clearly define the behaviours that VBN expect and detail how our workforce
is expected to interact with the local community both on worksites and in the local
area generally.
Compliance with the site rules and the general behaviour of the workforce will be
managed and monitored by the VBN project team, through site inspections, audits
and safety tours, the requirements will be reinforced through regular operatives‟
briefings, site posters and project communications.
This document presents the first step in communicating our approach to
stakeholders. At the time of writing, much of the construction methodology is being
refined. Further information will be communicated as it becomes available through
the processes described in section 4 (in particular the CLG).

o Removal of brick retaining wall adjacent to Kent Stairs in parallel.
4.2 Ground Treatment Works
Due to the position of the existing London Underground tunnels, services, site
constraints and ground conditions that exist at this location, the majority of the new
tunnels will need to be constructed through water bearing Terrace Gravel deposits.
The tunnels that connect the new Northern Ticket Hall with the Victoria Line
Concourse and the District & Circle Line will be constructed using Sprayed Concrete
Linings. In order to prevent excessive groundwater ingress and ground losses, the
gravel deposits will be treated to form a protective canopy around the tunnel profiles.
Sequence of construction:

When the site has been cleared of surface obstructions and remaining services
have been located and marked, trial holes will be excavated and sacrificial
sleeves installed

A drilling rig will then be used to bore through obstructions and overburden for the
subsequent installation of a duct to approximately 4m depth

Prior to drilling, the rig instrumentation and site monitoring system will be checked
to ensure that it is operating correctly and that nearby services and buildings are
within acceptable movement limits
Page 16 of 54
London Underground
Code of Construction Practice part B – Victoria Station Upgrade
Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011

When all of the ducts have been installed for each jet grout column in the
worksite, the spoil management system will be established. This will comprise a
means of collecting the liquid drill flush or jet grout spoil at the top of the jet grout
column and pumping away from the working area

Grout and water arisings from the jet grout columns will be collected at the ground
surface and pumped via the pre-laid grout pipes to the Spoil Holding silos / tanks
located in the Elliott House and Terminus Place Worksites. Grout spoil flow in the
pipes will be assisted by the addition of compressed air or water

Drilling will be carried out using a weak cement grout flush to the base of the jet
grout column with the nozzle positioned at the treatment zone.

Where necessary, the stiff London Clay will be pre-cut using a water / weak grout
jet as the rods are rotated and lifted out of this layer. The drill rods will then be reinserted to the base of the column and the full column pre-cut from the bottom to
the top.

After pre-cutting, the rods will be reinserted to full depth again and the column jet
grouted using the cement grout mix

Post treatment testing will be carried out on the grouted soil matrix to ensure that
the ground treatment meets the pre‐determined strength and permeability
characteristics
4.3 Tunnelling Works
The majority of the tunnels will be constructed and lined using Sprayed Concrete
Primary Lining, and then completed with a waterproofing membrane and secondary
concrete lining. A small amount of work will be carried out in more traditional timber
heading and break-up and will be confined to competent London Clay.

Tunnel excavation and primary support
Before excavation can begin, additional roof support is to be installed. Excavation
will then be carried out using an excavator, and spoil moved from behind using a
side loader tipping onto a belt for transport to the pit bottom muck skip

Install primary lining
The shotcrete primary lining will be applied using robotic spray equipment in
accordance with the design requirements.

Tunnel waterproofing and secondary lining
The tunnel waterproofing and placing of concrete secondary lining to the tunnels
follows completion of the primary lining. Following installation of the waterproofing to
an area, reinforcement will be fixed as required. The secondary concrete lining
formwork is intended to be travelling formwork, formwork sections being made up in

3m lengths, made up of a series of hinged steel pans which can be erected and
striped using hydraulic rams

Temporary propping to existing tunnels / Temporary works
Some of the proposed new tunnels run in close proximity to the existing running
tunnels and pedestrian access tunnels. During construction of the proposed new
tunnels, ground supporting the existing tunnels will be removed. Therefore,
temporary support to the existing will be required until the new tunnel is structurally
complete. This will also apply to areas of break ins/outs from new to existing
4.4 North Ticket Hall Construction.
In order to maintain the safe operation of Bressenden Place, the North Ticket Hall
(NTH) box structure will be constructed in two halves, with the road alignment
amended to suit the construction phasing. Following the demolition of the existing
structures (as detailed above), the alignment of the Bressenden Place carriageway
will be amended to facilitate the establishment of the construction worksite on the
western side of Bressenden Place.
A perimeter secant piled wall will be constructed using standard rotary auger piling
techniques, with the upper sections of the piled wall cased to ensure continued
support to the existing sand and gravel strata. In conjunction with the secant piles,
large and small diameter bored piles will be installed within the confines of the box
structure. Temporary sheet piles will be installed at the boundary between the two
halves of the box to ensure that the existing carriageway is effectively supported
throughout the construction process.
Upon completion of the piling works, the structure will be excavated to the underside
of the roof slab level and the reinforced concrete capping beam and roof slab
constructed over the western half of the NTH structure. Once the concrete slab has
reached the required strength, the existing Bressenden Place carriageway will be realigned over the new structure, to facilitate the construction of the eastern half of the
NTH box structure.
The construction of the eastern half of the NTH box will follow in a similar sequence
to the western section with the installation of the secant piled wall and bored piles.
The reinforced capping beam will then be constructed and precast concrete beams
installed across the box to provide support to the piled wall. The NTH box will then
be excavated to the underside of the ticket hall slab level and the reinforced concrete
slab constructed. The precast concrete roof structure will then be installed onto the
precast beams and a reinforced concrete capping slab cast over the roof structure.
The box construction will then proceed „top down‟ with the remaining levels
excavated and reinforced concrete slabs constructed in sequence.
In parallel with the top down construction of the NTH box, a new glazed entrance
structure will be constructed at the corner of Bressenden Place and Victoria St and

an above ground ventilation structure will be constructed using standard reinforced
concrete techniques. Following completion of the NTH excavation and construction,
the Bressenden Place road and pavements will be reinstated to their original
alignment,
Following the completion of the construction activities, the architectural finishes and
services (mechanical, electrical, power and communications) installation will
commence in a phased manner. The installation of the services will be undertaken in
the normal manner with the „first fix‟ being undertaken in conjunction with the
construction of blockwork walls and partitions and the „second fix‟ in conjunction with
the installation of the architectural finishes. Following the completion of the services
installation, the new systems will be inspected, commissioned and tested prior to the
new assets being opened for public use.
4.5 South Ticket Hall Construction.
The South Ticket Hall (STH) construction will commence immediately after the
Olympic Embargo period, with the establishment of the construction worksites and
the decommissioning and demolition of an area of the existing Victoria Line ticket
hall and the Network Rail station‟s basement.
A perimeter secant piled wall will be constructed using standard rotary auger piling
techniques, with the upper sections of the piled wall cased to ensure continued
support to the existing sand and gravel strata. In conjunction with the secant piles,
large and small diameter bored piles will be installed within the confines of the box
structure.
Upon completion of the piling works, the reinforced concrete capping beam along the
perimeter of Wilton Rd will be constructed and the box structure excavated to the
underside of the ticket hall slab level. The reinforced concrete ticket hall floor slab
will then be constructed using precast and cast insitu reinforced concrete elements.
The new roof slab will then be constructed, together with the internal supporting
columns, with an access area left open above the proposed escalator portal to
facilitate the remaining STH construction activities and future tunnelling construction
works.
Once the roof slab and ticket hall slab have reached the required strength, the
remaining excavation for the plant room level, will be undertaken in a „top down‟
manner, with the floor slab cast in sections to ensure the continued stability of the
structure.
In parallel with the top down construction of the NTH box, a new glazed entrance
structure will be constructed in front of the Network Rail Station, which will

incorporate a new an above ground ventilation structure. Following completion of
the STH excavation and construction, the „beach‟ will be reinstated.
Following the completion of the construction activities, the architectural finishes and
services (mechanical, electrical, power and communications) installation will
commence in a phased manner. The installation of the services will be undertaken in
the normal manner with the „first fix‟ being undertaken in conjunction with the
construction of blockwork walls and partitions and the „second fix‟ in conjunction with
the installation of the architectural finishes. Following the completion of the services
installation, the new systems will be inspected, commissioned and tested prior to the
new assets being opened for public use.

areas as appropriate.
As the project progresses additional stakeholders may emerge and they will be
included in works notifications and other project communications as appropriate.
These communications would typically be to inform parties of any proposed works,
the nature, timing and planned disruption, measures to reduce the impact of these
works, the helpline telephone number and address to which any enquiries should be
directed. Advance notice of works will be sent out at least two weeks prior to their
commencement.
Page 20 of 54
London Underground
Code of Construction Practice part B – Victoria Station Upgrade
Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011
The contractor shall maintain regular communication to ensure that the wider
community and other stakeholders and affected parties are kept well informed.
Regular newsletters providing information on the works will be distributed to local
residents and businesses and other key stakeholders. The works update page on
the TfL website will be updated on a monthly basis or as appropriate. VBN will also
provide on a regular basis an update of the schedule of work to CoW.
The Community Liaison Group (formerly the Shadow Community Liaison Group see
CoCP Part A - 2.5.2) is an established forum through which a timely and informed
discussion of the works can take place. The CLG aims to keep representatives of
local residents and businesses informed about the work and provide an opportunity
to raise matters of interest or concern. The CLG terms of reference can be found in
Appendix 3. It is comprised of representatives from TfL, LU, CoW and local
businesses and residents and meets at least once every two months. The
Community Liaison Group will continue to meet on a regular basis throughout
construction.
A 24/7 helpline was set up to deal with queries and complaints relating to the utilities
diversion works. This facility will continue throughout construction. For more
information on the helpline please refer to section 2.5.4 of the CoCP Part A.
A complaints procedure has been developed to ensure that all complaints received,
relating to the construction of the project, are dealt with efficiently and in an
appropriate timeframe. This is presented in Appendix 2.
Project web pages can be found at www.tfl.gov.uk/vsu providing general information
on the project, regular progress updates, details of forthcoming works, any impacts
on travel arrangements, relevant publications including minutes of CLG meetings
and contact details.
6 Public Access and Highways
The TWA Order authorises the carrying out of specified highway works (including to
pedestrian and/or cycle routes). These are set out in the relevant articles and
Schedules of the Order. These do not therefore require the further approval of the
highway authority, although in all cases VBN will consult with them on the timing and
scope of any highway works.
Where works are not authorised by the TWA Order, VBN will obtain approval of the
highway authority for any highway works. The works shall be undertaken to
standards suitable for highway adoption.
VSU participates fully in the Victoria Transport Board a strategic steering group
meeting, where key management decisions relating to the Victoria area are made
and guidance is given to assist projects and to maintain capacity of the network. This
allows Tfl and local authorities to consider the cumulative impact of construction
projects in the area and take appropriate actions to mitigate adverse cumulative
effects.
Page 21 of 54
London Underground
Code of Construction Practice part B – Victoria Station Upgrade
Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011
VBN will consult with all relevant stakeholders, including local residents and
businesses regarding the proposed traffic management arrangements required to
facilitate the VSU construction. This will allow alternative arrangements (if
necessary) to be agreed and implemented in a timely manner.
All of the traffic management schemes developed for the construction phases have
assumed implementation of the general traffic diversion route via Eccleston Bridge
and Buckingham Palace road, thus restricting Wilton Road use to taxis and buses
only. Following consultation with TfL and CoW, VBN have proposed a servicing
strategy for Allington Street due to the required restrictions imposed on Wilton Road.
The following construction worksites requiring access/egress via the strategic
network are as follows:



North Ticket Hall compound with access from Allington Street and
Bressenden Place.
South Ticket Hall compound with access from Wilton Road.
Intermediate Ground Treatment worksite compounds, located on
Terminus Place, Victoria Street, Allington Street and Wilton Road will
be accessed via each specific road/street accordingly.
Parking for all VSU-related vehicles will be provided within the construction
compounds in order to ensure construction traffic impacts on local residents and
businesses are minimised. Controls shall be put in place by VBN on roads adjoining
the sites if necessary to prevent parking by site workers. VBN will encourage site
workers to travel by public transport or to walk or cycle.
Traffic management arrangement drawings are presented at CLG meetings and
discussed with the appropriate parties as further information is developed. Due to the
ongoing development of these proposals it has been agreed that this means of
dissemination is preferable to the inclusion of these drawings in the CoCP Part B.
7 Water Resources
There are no surface watercourses within the area of the scheme. The scheme‟s
engineering design does not contain major interventions in the water environment.
The permanent works are mostly below ground with founding levels within the
London Clay and so there will be no effects on the underlying deep aquifer. The cut
and cover elements will be reinstated such that there will be little change in the area
of hard surfacing at ground level and thus little change in the rates of surface runoff
to the combined sewer system.
VBN will take all reasonable steps to ensure that there is no adverse impact on
groundwater resources as a result of the proposed works. In this regard VBN will
maintain close liaison with the Environment Agency.

7.1 Site Drainage
Initial negotiations have begun with Thames Water regarding the proposed
discharge of waste water from the site. Waste water is expected from dewatering,
over pumping and most significantly the jet grouting operations. In due course it is
likely that a further consent for trade effluent (from site cabins) will also be obtained.
7.2 Surface Water Pollution Control
The VBN team will ensure that the protection measures (illustrated in section 7 of the
CoCP Part A) to control the risk of pollution to surface water will be adopted. In
addition the following steps will be implemented where appropriate and reasonably
practicable:
o Any such container will be kept on site within a lockable storage place with the
lid securely tightened. It shall also be stored on impermeable bunds. These
measures will be checked and audited against during Environmental and
Health and Safety Site Inspections.
o Instead of drip trays, the site will adopt plant nappies:
o Plant nappies are designed to withstand all weather conditions. While
encapsulating any drips or spills of oil the mat allows passage of water,
such as rainfall, thus eliminating costly emptying of contaminated trays
after use. The plant nappies can be stood on uneven ground or slight
inclines with no loss of performance. The traditional drip tray have
therefore been replaced with the plant nappies as an easy and costeffective way to ensure environmentally friendly practice on site,
avoiding possible contamination of ground and water. The correct use
and availability of plant nappies will be checked and audited against
during Environmental and Health and Safety Site Inspections.
o Localised jet washing of wheels on hard standing and a road sweeper
employed when required.
o Settlement tanks (Silt busters), water filters and hessian matting to drains will
be used to ensure that silt does not enter the surface water drainage network.
7.3 Groundwater Pollution Control
o Potentially contaminative materials (such as oils and lubricants) that may be
used or stored on site during the construction will be controlled and managed
in accordance with the CoCP Part A in order to minimise the risk to surface
waters and groundwater resources
o Water containing silt will be minimised and intercepted as specified in the
CoCP Part A in order to minimise the risk to surface waters
o Discharge of water will be undertaken through appropriate routes and at
appropriate locations subject to the necessary approvals being obtained from
the Environment Agency and Thames Water and in accordance with the
CoCP Part A

Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011
o It is anticipated that VSU works / dewatering will only affect the shallow (and
not the deep) aquifer and no licensed abstractions or Protected Rights will be
affected
8 Noise and Vibration
VBN will abide by the measures illustrated in section 5.0 of the CoCP Part A for
management of noise and vibration from the works including working hours, the
requirement for Section 61 consents under the Control of the Pollution Act 1974 and
monitoring.
Details of all Section 61 consents will be communicated to stakeholders through the
CLG and those measures illustrated in Section 4 of this document. This is to ensure
that VBN can take account of individual concerns over the works methodology,
mitigation measures or monitoring proposals prior to submission to City of
Westminster for approval.
8.1 Noise and Vibration Receptors
The Environmental Statement predicted that airborne noise from surface
construction activity will affect the following properties during the daytime:
o 20 Palace Street
o The Stag Public House (PH)
o Allington Street - south and west side (from Kings Arms PH to the Stage Door
PH)
o Allington Street - north and east side (from the Royal Westminster Hotel up to
the Duke of York PH)
o 314 – 316 Vauxhall Bridge Road
o Carlisle Place - west side (from 76 to 85 Carlisle Place up to and including 1 –
14 Evelyn Mansions)
o Carlisle Place - east side (from 1- 5 Cardinal Mansions up to and including the
rear of Ashley Court)
At night, the Stag PH and those parts of 1 – 20 Allington Court above 7 – 9 Allington
Street will also be affected by airborne noise.
Monitoring arrangements illustrated in 8.4 are positioned to ensure that a „worst
case‟ assessment of noise and vibration impacts can be made. This will ensure that
an accurate prediction of the impact on the receptors illustrated above is maintained
throughout the works and appropriate mitigation measures (illustrated in 8.3) can be
implemented to ensure that the thresholds illustrated in Appendix 2 of the CoCP Part
A are not exceeded. Should it be predicted that these thresholds will continue to be
Page 24 of 54

Code of Construction Practice part B – Victoria Station Upgrade
Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011
exceeded despite the mitigation measures on the works proposed in 8.3, then
mitigation at receptors will be offered prior to the works including rehousing or noise
insulation and implemented in advance of those works commencing.
A plan of the residential areas in the vicinity of the VSU works is presented in
Appendix 1.
8.2 Foreseeable Construction Method, Programme and Working
Hours
The VSU works (illustrated in section 4) include several construction activities that
could potentially generate significant levels of noise and / or vibration. In addition
most of the tunnelling works are required to be undertaken on a five day week, 24
hours a day basis to prevent deformation of settlement.
The activities that could potentially cause high levels of noise and vibration and any
activities required to be undertaken outside of normal working hours are discussed in
further detail within the following sections.
All works will be subject to the Section 61 consent process with the City of
Westminster and VBN will provide a copy of the Section 61 applications to the CLG
in advance of submission to City of Westminster. A schematic of this process is
included below.

8.3 Foreseeable Site Specific Noise and Vibration Mitigation
Civil engineering works in the Victoria area are likely to create a nuisance to
neighbouring properties. However, we will strive to minimise this nuisance level
whenever practicable.
Page 25 of 54
London Underground
Code of Construction Practice part B – Victoria Station Upgrade
Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011
VBN shall comply with the requirements of the Control of Pollution Act 1974 with
particular relevance to Part III, the Environmental Protection Act 1990, the Noise at
Work Regulations 1989 and the Health and Safety at Work Act 1974. As previously
stated all specific mitigation for each section of works will be included in the Section
61 application for consent which will be communicated well in advance of the works
being undertaken. An example of the likely mitigation to employ is given below.
Best Practicable Means‟ (BPM) (as outlined in Section 72 of the Control of Pollution
Act 1974) will be employed in order to minimise noise and vibration levels throughout
the period of the works. General measures will include the following as appropriate:
 Ensure adequate planning within LUL sites to prevent noise generating from
double handling of materials or overlapping of high noise activities.
 Ensure plant conforming to SI 2001/1701 (UK implementation of EC directive
2000/14/EC on noise emission) will be used if placed on the market or put into
service since January 2002. Plant put into service or put on the market before
that date shall conform to SI 1985/1968 (as amended) or to SI 1988/361 (as
amended) as appropriate to the type of plant.
 VBN will use only plant which complies with the relevant EU / UK noise limits
applicable to that equipment or is no nosier than would be expected from the
noise levels quoted in BS 5288:1997. VBN also will maintain that plant
properly and operate it according to the manufactures‟ recommendations.
Electrical or LPG powered plant will be used (where practicable) rather than
plant powered by a combustion engine. All plant powered by combustion
engines will be fitted with suitable silencers. Where practicable, rotary drills
and bursters actuated by hydraulic or electrical power will be used for
excavating hard material. Items of plant in intermittent use will be shut down
when not in use.
 VBN will locate all stationary plant so that the noise impact at all occupied
commercial and residential buildings is minimised, and wherever practicable,
every item of static plant shall be sound attenuated using methods based on
the guidance given in BS 5228.
 Equipment to be sited as far from sensitive receptors or as close to any
acoustic screen located between the activity and the receptor as reasonably
practicable
 Minimise drop heights.
 Ensure compressor covers closed when they are running, and lined and
sealed where possible.
 Ensure machinery panels are secured and do not rattle.
 Ensure adequate maintenance of equipment and machinery.
 Ensure machinery is not running unnecessarily, or in the lowest noise output
mode.
 Site fencing will be erected and will be maintained throughout the project
duration. All knot holes, cracks and joints will be sealed. The fencing will be of
safe and durable construction. Temporary fencing will be lined and where it
encloses noisy work the lining will provide acoustic mitigation.
 VBN will retain full control over and responsibility for Trade Contractors
working on the site. Trade Contractors will be required to submit full details of
work programmes, plant and personnel and will be made fully aware of the
requirement of the Section 61 Consent.

Construction of early temporary infrastructure to minimise noise – e.g. site
hoardings. These will be designed to provide the best acoustic screening
available and where practicable – doors and gates will not be located opposite
noise sensitive buildings.
Use of bending as opposed to percussion methods to break out concrete.
Rotary drills and bursters actuated by hydraulic or electrical power should be
used for excavating hard materials.
Selection of piling methods which minimise noise and vibration.
Noise reduction methods for temporary ventilation equipment
Where practicable, concrete pours to be scheduled to begin prior to 13:00 so
as to ensure that they do not overrun past 18:00.
Choice of routes for transport, spoil and personnel to minimise noise at noise
sensitive buildings
Ensure that sub-contractors and suppliers are aware of the environmental
constraints of the site and follow the necessary procedures for
Environmentally Responsible Working Practices.
Prevent any unnecessary noise such as shouting or banging at all times.
Ensure Site Induction sessions cover Environmentally Responsible Working
Practices and Environmental Awareness especially with regard to noise
amounting to nuisance.
Put up signs within the Sites to raise awareness and to stress the importance
of noise control and its impact on the local residence.
Flyers to local residents two weeks before commencement at a new site
making them aware of forthcoming activities.
Signage around the sites displaying the VSU helpline number. Operative‟s
induction training will include the requirements relative to BPM as regards
noise and vibration.
Vibration monitoring will take place during construction work times as
appropriate, i.e. during the tunnelling works or certain percussive breaking
works.
No personal radios on site.
Arranging delivery / materials transfer points away from noise sensitive
boundaries.
Arranging delivery times to minimise impact.
Switching off noisy equipment when not needed.
Observing restrictions on working hours.
Changes to proposed method of work or alternative systems to reduce impact
of noise
Solid (or screened) doors and gates will not be located opposite sensitive
receptors. The operation of gates should be controlled to minimise the time
they are open for the passage of vehicles, thereby minimising stray noise
emissions.
All plant to be maintained regularly to comply with relevant national or
international standards
Temporary infrastructure (i.e. haul roads) should be constructed of materials
that minimise noise and vibration (i.e., laying a tarmac surface)


Handling all materials, particularly steelwork, in a manner which minimises
noise. For example storing materials as far as possible from sensitive
receptors and using resilient mats around steel handling areas.
 The VBN team shall, as far as reasonably practicable, ensure that the noise
from reversing alarms is controlled and limited. This will be managed through
the following hierarchy of techniques:
(a) The site layout will be designed to limit and where reasonably
practicable, avoid the need for the reversing of vehicles. The VBN team
will seek to ensure that drivers are familiar with the worksite layout; A3
posters will be displayed on site notice board and at key locations to
show the site layout while traffic marshals will be directing the drivers at
all time
(b) Banksmen will be utilised to avoid, as far as reasonably practicable, the
use of reversing alarms
(c) Reversing alarms incorporating one of more of the features listed
below or any other comparable system will be used where reasonably
practicable
 Highly directional sounders
 Use of broadband signals
 Self adjusting output sounders
 Flashing warning lights
Sub-contractors (i.e. haulage contractor) will be required to provide evidence of at
least one the above at the procurement stage.
Additionally specific measures such as those identified for the tunnelling works below
will be identified and implemented for particularly noise activities.
Although much of the tunnelling works will naturally take place underground, the
pitheads running 24 hours a day can create nuisance if uncontrolled. VBN will
minimise the pithead disturbance by:
 Closeboard hoarding the site with strategic viewing points to allow interested
members of the public to see in but minimise visual disturbance to neighbours
 Arranging the lighting on site to be directed inwards and downwards thereby
minimising any light nuisance to neighbouring properties
 Arranging wherever possible for lorries to drive through the site and minimise
reversing, thereby reducing noise caused by vehicle reversing alarms
 Setting up the site so that tunnel arisings are transferred to overhead muck
bunkers, thereby minimising vehicle movements by removing the need for a
loading shovel
Tunnel works are planned to be worked continuously over 24 hours. To minimise
noise, plant on the surface will be primarily electrically operated, and diesel plant,
such as generators, will be silent packed. The main environmental concern affecting
the public will be noise at night and specified noise restraints during performances in
the Victoria Palace and Apollo Theatres. Noise monitoring will be carried out, and if
necessary additional measures will be put into place to satisfy these requirements.

8.4 Noise and Vibration Monitoring
The following noise and vibration monitoring locations shall be used by VBN. These
locations have been selected due to their close proximity to the construction
activities that may generate noise and vibration.
Noise monitoring equipment is delicate and complex, and requires continuous
management both to ensure its continued accurate operation and to assess the
results that it produces in a timely manner. It is essential that monitoring locations
are selected to be readily accessible, free from tampering and as far as practicable,
unaffected by extraneous noise. VBN propose to use advanced equipment which
includes an audio recording ability, which can take sample during high noise events
to help to ascertain the noise source.
VBN are considering mainly roof-top locations to meet the above requirements and
to avoid privacy issues that might otherwise occur from audio recordings. VBN
sought the advice of a recognised expert consultancy (Noisemap) to provide
comments on the proposed monitoring locations as to their suitability and sufficiency.
The noise monitoring locations proposed include.
1. The Stag PH (southern end)
2. Thistle Hotel
3. 7 Allington Street
4. Victoria Palace Theatre (north-eastern corner)
5. 1-14 Evelyn Mansions (Carlisle Place side)
6. The Peak (Vauxhall Bridge Road side)
Long-term monitoring points should be selected to provide adequate detection of
significant deviation of noise impact from that predicted in the ES, and that there is
provision for short-term monitoring to investigate issues that arise. The main
purpose of the monitoring is to detect the occurrence of noisy operations: the
locations affected by the work are relatively easy to predict, and so it is not
necessary to monitor at every affected location. It is best to have the monitoring
points at noise-sensitive receivers close to the source of noise.
On this basis and considering the noise prediction exercise presented in the ES,
Noisemap consider that the receptor at 20 Palace Street not required: the reason for
prediction of significant effect arises because ambient levels are fairly low.
Page 29 of 54
London Underground
Code of Construction Practice part B – Victoria Station Upgrade
Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011
Noisemap consider that construction noise is likely to be audible on a limited number
of occasions, and that generally it will be difficult to localise it from a monitor at that
location. Consequently it is not helpful in detecting and controlling any unexpectedly
noisy work.
Noisemap also consider that the proposed receptor at the Duke of York PH is not
required. It is located in a very noisy area, affected by traffic noise, and so it will be
difficult to separate construction noise from ambient for most of the time. It will
therefore be of limited help to control construction noise, or to compare with
predictions. It is also close to other monitoring points at 3 and 4 in the above list,
which will be better for monitoring and control.
Noisemap state that the other points are well-distributed and located for the
requirements.
VBN will maintain one set of noise monitoring equipment for short-term deployment
should a problem arise unexpectedly.
The vibration monitoring locations proposed include.
1. Victoria Palace Theatre
2. Apollo Theatre
3. The Stag PH
4. 7 Terminus Place
5. 4-6 Terminus Place
6. The Peak
VBN intends to present these proposed monitoring locations subject to discussion
and agreement with the City of Westminster as part of the Section 61 consent
process.
Monitoring will begin in March 2011 so that for ambient baselines to be established
(and checked against those presented within the Environmental Statement). All
monitoring will be undertaken using type 1 class noise monitors and data
downloaded a minimum of once a week, but also after any complaints have been
received to aid investigation and resolution of the complaint.
Noise and vibration monitors are fitted with alarms to enable monitoring against
trigger levels. These are defined in the CoCP Part A – Appendix 2 (for noise) and
specific 3rd party agreements for vibration.
Page 30 of 54
London Underground
Code of Construction Practice part B – Victoria Station Upgrade
Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011
Noise monitors that detect an elevated noise reading (averaged over the appropriate
timescale (as per Appendix 2 of CoCP Part A) will send a text to the VBN site
manager and environmental manager so that they can take appropriate action to
mitigate impact. This enables an instant response to a potential problem.
Vibration monitors will have their alarms set at a trigger level defined by the
agreement with the building owner / occupier or best practice. These will also be
enabled to provide real-time alerts of breaches so that action can be taken to rectify
the problem.
VBN shall also measure construction noise levels using a hand-held meter where
works required (for instance inside the operational Victoria station). The frequency
and location of these surveys will be dependent upon the nature and sensitivity of
the works being undertaken.
All noise and vibration monitoring will be made available to CoW as part of the
Section 61 process. The data shall be presented in a format which shall be agreed
with the CoW and easily interpreted by non-technical third parties.
8.5 Pre-construction ambient noise survey
The pre-construction ambient noise survey is due to be conducted in March 2011. A
survey was undertaken as part of the Environmental Statement (6.3.6). This is
summarised below:

9 Dust and Air Quality
VBN will comply with the general measures to control air quality impacts as detailed
within the CoCP Part A section 6.3. VBN will also comply with the guidance set out in
the “London Best Practice Guidance: The control of dust and emissions from
construction and demolition (Greater London Authority and London Councils
November 2006)”.
Technical Appendix C of the Environmental Statement provides an assessment of
each of the activities within the works methodology. This assessment has allocated
each activity with tier number (1-3) according to its dust raising potential. This
corresponds with the tiered mitigation measures specified in the CoCP Part A 6.3. If
the works methodology assumptions on which the air quality assessment was based
change sufficiently to render the assessment unreliable then VBN will arrange for a
reassessment.
9.1 Dust Receptors
Considering their proximity to the works, the following have been identified by the
Environmental Statement (6-32) as potentially the most sensitive receptors in the
proximity of the VSU worksites:
o
o
o
o
o
o
o
o
o
o
o
o
Westminster City School and Sixth Form;
St Vincent De Paul RC School;
Burdett Coutts CE Primary School;
St Peter's Eaton Square CE School;
Victoria NHS Walk In Centre;
Belgrave Dental Practice
Dental Surgery, 42a Buckingham Palace Road.
The Wilton Dental Practice
Westminster Choir School
Bentley House, Carlisle Place
Lookahead Hostel, Castle Lane
College Park School, Castle Lane
There are also a number of residential receptors in the local area which could
potentially suffer degradation in air quality:
o
o
o
o
o
o
Allington Street zone
Vauxhall Bridge Road to Ambrosden Avenue zone
Buckingham Palace Road zone
Palace Street zone
Ambrosden Avenue to Howick Place zone
Southern Periphery zone
These residential areas are illustrated in Appendix 1.

9.2 Activities requiring specific consideration for dust mitigation
measures
The CoCP Part A (6.3.6) provides a range of mitigation measures corresponding to
the relevant tier number (1-3) / dust raising potential of the works. Figure 2 in
Appendix 1 illustrates the predicted dust raising potential of the works during the
production of the Environmental Statement.
If considered relevant (i.e. the works methodology has changed significantly) VBN
may commission another assessment of the dust raising potential. Details of this will
be included in the Section 61 application for the works.
All of the dust controls for the relevant tier (see 6.3.6. CoCP Part A) will be
implemented during the VSU works. This will follow the hierarchy below:
Prevention - The works methodology and site setup will be planned to eliminate as
far as possible the dust raising potential of the works. This could include stripping out
the buildings prior to demolition or installing hard standing on the sites as early as
possible in the programme of works.
Suppression – Where prevention measures cannot eliminate the potential for dust
then methods of suppression will be used. Examples of this are included within
CoCP Part A (6.3.6) and include the use of water suppression for demolition and
during the excavation works or the use of road sweepers on the pubic highways. The
method of suppression will be selected with relevance to the works being
undertaken.
Containment – In the event that prevention and suppression methods have been
taken and a potential for dust remains then where possible methods of containment
will be used such as the screening of buildings during demolition.
Measures to minimise dust during construction will be agreed as part of the Section
61 process prior to works being undertaken and details of this will be communicated
to stakeholders in advance of the works.
With the provisions specified in the CoCP Part A (6.3.7.) coupled with the mitigation
measures specified above it is not expected that dust deposition will occur as a
direct result of the works. Similar levels of demolition have been carried out at
Tottenham Court Road with no significant impacts. However VBN remain committed
to maintaining an excellent relationship with the local community and should dust
deposition occur as a direct result of the works VBN will make efforts to address the
concerns raised. If dust depositions occur because of a build up emanating from the
VSU and any other adjoining worksites, VBN will co-operate with other contractors to
address the problem of cumulative build up.

9.3 Dust Monitoring
VBN have commissioned King‟s College, London to provide an appropriate dust
monitoring strategy for the VSU project. VBN will ensure that this strategy will be
followed during the construction of the works.
The assessment in determining the most adequate monitoring strategy will look at:




Dust raising potential of construction activities
Proximity to potential receptors
Duration of construction activities at each location and
Mitigation measures / monitoring procedures outlines in the Method
Statements.
Low Risk
Where sites have a risk score that assigns them to the low risk category no dust
monitoring will be carried out.
Medium Risk
Where sites have a risk score that is in the medium risk category passive deposition
monitoring techniques (glass slides, Frisbee gauges or sticky pads) will be adopted
at appropriate locations (site boundaries/local receptors) according to specific site
conditions.
High Risk
If any activities are identified as high risk, existing baseline data will be obtained and
analysed prior to works commencement. Where practicable, VBN will seek for a
twelve month period of data sourced from local background PM10 concentrations
measured by the Automatic Urban and Rural Network (AURN) monitoring sites and
appropriate local authority automatic monitoring sites.
King‟s College consider that a network of four continuous particulate monitors should
be used to carry out monitoring around the main construction area boundary as
illustrated in the figure below.
Page 35 of 54
London Underground
Code of Construction Practice part B – Victoria Station Upgrade
Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011
Two of the particulate monitors will be located on or near to the site boundary, to
form a transect across the site. This will be set up in the direction of the prevailing
wind, in this case south westerly, in order to establish the local background levels
and assist in determining the relative contribution of dust emissions from the
construction site.
A further two monitors will be mounted on the upwind side of the site on the
boundary. The locations of these two analysers will take into account any particularly
sensitive locations, such as schools and the residential properties highlighted in 9.1.
Consideration will be made to outlet vents that may transport significant amounts of
particulate matter from construction activities underground.
Due to the complexity of the site and due to a considerable amount of work being
undertaken below ground level the exact location of the monitors will need to be
established in consultation with King‟s College following a site visit.
Meteorological sensors measuring local wind speed and wind direction will be colocated with the particulate monitor situated in the least enclosed area.
If practical and required for particularly sensitive receptors, VBN will install
monitoring instruments able to operate an alarm (PC based or mobile phone) when a
predetermined site action level is reached. If the alarm is triggered the following
actions will be taken:
The Environmental Manager or someone delegated by the Environmental Manager
will as quickly as reasonably practicable investigate activities on the site to ascertain
if any visible dust is emanating from the site or activities are occurring that are not in
line with dust control procedures.
At high risk sites, a site action level will be established by reference to local authority
and AURN PM10 monitoring data in consultation with the relevant local authority.

London Underground
Code of Construction Practice part B – Victoria Station Upgrade
Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011
Subject to consultation, a preliminary site action level of 250μg.m-3 (15 minute
average) will be adopted.
Dust monitoring will be continued at a medium or high-risk site until the site has a
risk score that assigns it to the low risk category. The cessation of monitoring when a
site no longer represents a high or medium risk is subject to consultation with and
the agreement of the local authority in whose area the worksite is situated that high
or medium risk no longer applies, provided that such agreement is not unreasonably
withheld.
10 Asbestos
VBN will ensure compliance with the measures specified in the CoCP Part A (9.3) at
all times. This includes compliance with The Control of Asbestos Regulations 2006
that came into force on 13 November 2006 (SI 2006/2739). The Regulations bring
together three previous sets of Regulations covering the prohibition of asbestos, the
control of asbestos at work and asbestos licensing. The Regulations prohibit the
importation, supply and use of all forms of asbestos.
VBN will adhere to the exposure limits and measurement methods for asbestos,
which are set out in the Health and Safety Executive (HSE) Guidance Note EH10
Asbestos Exposure Limits and Measurements of Airborne Dust Concentrations
2001. The contractor must comply with:

HSE Guideline Note MS13 Asbestos: Medical Guidance Notes 1999;

The Health and Safety Commission Approved Codes of Practice on: Work
with Asbestos Which Does Not Normally Require a License (L27), Work with
Asbestos Insulation, Asbestos Coating and Asbestos Insulating Board (L28)
and The Management of Asbestos in Non-domestic Premises (L127).

The COSHH Regulations 2002 (SI 2002/2677).
Measures for managing asbestos in alteration, demolition and excavation works will
include:
(a) Employing competent contractors to carry out alteration and
demolition works
(b) Contractors implementing a procedure for dealing with
potentially suspect materials exposed requiring sampling and
analysis by an independent specialist consultant
Page 37 of 54
London Underground
Code of Construction Practice part B – Victoria Station Upgrade
Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011
(c) Formal exchange of information before start of work, including
relevant information from the Asbestos Register to clearly
identify location of asbestos-containing materials
(d) Method statements for any works in the vicinity of asbestoscontaining materials to avoid any disturbance to such materials
which are not to be removed
Measures for managing work involving asbestos-containing materials encountered in
construction will include:
(a) Appointment of a specialist consultant independent of the asbestos treatment
contractor
(b) Ensuring any work with asbestos-containing materials is notified to the Health
& Safety Executive
(c) Ensuring any work with asbestos-containing materials is carried out by
licensed specialist asbestos treatment contractors in accordance with
Asbestos (Licensing ) Regulations 1983 ( SI 1983/1649 ) as amended in 1998
( SI 1998/3233)
(d) Requiring method statement defining detailed control measures to be
produced by the specialist asbestos treatment contractor and approved by the
independent specialist consultant
(e) Air sample monitoring by the independent specialist consultant of work to
ensure required air quality standards are achieved
(f) Disposal of asbestos-containing materials to licensed waste sites in
accordance with Hazardous Waste Regulations (2005).
11 Contaminated Land
The main source of contamination to have been identified from the desk study in the
Environmental Statement is made ground (sourced from cut and cover spoil from the
Circle and District Line, Grosvenor Canal basin infilling). A ground investigation was
conducted by Norwest Holst in 2006 which detected very slightly elevated lead
concentrations in soil. Also elevated concentrations of chloride, nitrate and sulphate
were detected in leachate samples.
Parts of the site are underlain by alluvium and peat. Carbon dioxide concentrations
of up to 7.6% were identified during the ground investigation. No in-ground
concentrations of either CH4 or H2S gases were recorded.
Page 38 of 54
London Underground
Code of Construction Practice part B – Victoria Station Upgrade
Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011
There are potential risks from the above contaminants and other contaminates
during the construction process to future site users, construction staff, surrounding
land users and newly built underground structures from land contamination but with
the incorporation of mitigation measures such as provision of personal protection
equipment, dust monitoring controls and the selection of appropriate construction
materials, no negative significant residual effects during construction or operation of
the scheme are predicted.
The VBN Environmental Manager or nominated deputy will carry out or organise site
assessments, investigations and/or risk assessments wherever construction work is
planned in order to assess the potential for contamination in both soil and
groundwater. The necessary measures will be agreed with the Environment Agency
and the Local Authority as part of the construction planning process.
As stated in the Code of Construction Practice Part A (8d), the VBN project team
shall keep a record of works undertaken to comply with the remedial strategy and
shall prepare and submit a verification report to the VSU Project Manager for
acceptance within four weeks of completion of the remediation. Once acceptance
has been obtained from the VSU Project Manager, VBN shall issue the verification
report to the Environment Agency and the local authority.
12 Archaeology
VSU is located in an area which includes no designated sites of archaeological
importance though the area has some paleo-archaeological interest. The works
could impact upon previously unrecorded archaeological remains. .
A strategy for archaeological mitigation will be agreed with CoW in consultation with
English Heritage (EH) and in accordance with the archaeology condition of the
deemed planning permission. This condition, which is essentially the same as the
condition agreed by LUL, CoW and English Heritage prior to the close of the VSU
Public Inquiry, states:,
15.
No individual stage of the development shall commence until a programme of
archaeological work has been implemented in accordance with a written scheme of
investigation relating to that stage that has been submitted to, and approved in
writing by, the local planning authority. The programme is to comprise an
archaeological evaluation, a review of the evaluation results and method statements
for any works necessary to mitigate impact.
VBN will apply a results-led archaeological approach to each of the following seven
project evaluation areas (PEAs):
PEA 1:
North Ticket Hall Worksite;
Page 39 of 54
London Underground
Code of Construction Practice part B – Victoria Station Upgrade
Reference VBN-V047-1159-ENV-PLN-000142 – Revision 5 – 22/06/2011
PEA 2:
South Ticket Hall Worksite;
PEA 3:
Allington Street Area, including the Duke of York;
PEA 4a-d:
Shafts 2, 9,12A and 29 respectively.
On approval of this strategy, individual evaluation detailed designs will be developed
for each of the PEAs, which will also include specific objectives, methodologies and
programmes for each area. These will be made available to the heritage consultees
for comment prior to any work commencing. The evaluation fieldwork may be
frontloaded to minimise the requirement for intrusive investigations during
subsequent works. Should this reveal a requirement for any further work,
subsequent WSIs would be agreed with CoW (in consultation with EH) and
undertaken to allow discharge of the project Planning Conditions.
13 Listed Buildings and Conservation Areas
There are six Listed Buildings located within the vicinity of the works, these are;






Victoria Palace Theatre (Grade II),
Victoria National Rail Station (Eastern) (Grade II),
Victoria National Rail Station (Western) (Grade II),
Little Ben Clock Tower (Grade II),
Grosvenor Hotel (Grade II*),
Apollo Victoria Theatre (Grade II).
Following assessment of the impacts of the works on these Listed Buildings, three
separate Listed Building Consent applications were made and conditional approval
granted to cover the works affecting Victoria Palace Theatre, Victoria National Rail
Station and Little Ben Clock Tower. Prior to commencing the works a number of
submissions will be made to Westminster City Council, who shall consult with
English Heritage, to discharge the Listed Building Consent conditions.
The assessed impact on the two remaining Listed Buildings is deemed to be nonsignificant due to the implementation of BPM mitigation measures during the works.
The Westminster Cathedral and Grosvenor Gardens Conservation Areas are located
adjacent to the works but are not directly affected.

Appendix 2 – Complaints Procedure
1.0
Introduction
We recognise the importance of complaints as a valuable form of feedback and we are
committed to using this information to help drive forward improvements.
Anyone wishing to complain about any aspect of the VSU construction will find contact
information: displayed on hoardings (included in all correspondence to local residents and
businesses; and on the VSU website (www.tfl.gov.uk/vsu).
This complaints procedure will operate for the duration of the VSU construction. It complies
with the guidelines set out it LU‟s Customer Feedback and Complaints Policy.
2.0
Complaints Procedure
All complaints received in relation to the VSU project (e.g. written, via the telephone helpline,
the CLG or direct to station staff or site personnel) will be logged in a complaints register.
This will record the nature of the complaint, the action taken and the outcome.
If a complaint is received from someone indirectly related to the project, such as a member
of the station staff, and VSU is made aware of this, the VBN Stakeholder Manager will
contact the complainant directly and request clarification of their complaint so that it may be
accurately recorded and actioned.
The VBN Stakeholder Manager will work closely with LU‟s Stakeholder Communications
Executive to ensure that any complaints received direct to LU, relevant to the construction of
the project, are added to the complaints log and followed up as appropriate.
3.0
24/7 helpline
Our aim is to construct the VSU scheme safely and minimise disruption wherever
practicable. However, we do accept that occasionally things may go wrong. If anyone is
unhappy about any aspect of the construction work we would like to hear from them.
A 24/7 helpline has been established to ensure that we can respond to complaints efficiently,
and where necessary immediately. This is a dedicated helpline for the VSU project and is
operated by people who know about the project and have direct contact with key personnel
(site managers etc). The helpline is staffed 24/7 and is also the first point of contact and
information in an emergency.
A flow chart showing how complaints to the helpline are managed is attached at Appendix 2.

Responsibilities
The VBN Stakeholder Manager will be responsible for maintaining the complaints register
and will co-ordinate and actively track all outstanding complaints to ensure they are resolved
in an appropriate manner and timeframe. A report of the complaints register will be issued to
the Community Liaison group (CLG), and thus to Westminster City Council, at each CLG
meeting (every two months) or as required.
The VBN Stakeholder Manager will liaise with the LU Stakeholder Interface project
managers and TfL / LU communications colleagues. To ensure that LU is aware of all
complaints and to co-ordinate LU‟s input to responses where appropriate. All complaints
relating to Surface Transport issues (buses, taxis and road network) and VSU will be logged
but passed to Surface Transport Communications to respond. The outcome will be noted on
the complaints register.
6.0
Timescales
If the complaint cannot be resolved immediately we will endeavour to respond within 10
working days. If we are unable to resolve the complaint within 10 working days we will send
an update within that timeframe.
7.0
Escalation
If the person who has complained is not satisfied with the initial response the project team
will make every effort to try and resolve their complaint until the project has exhausted its
authority and further action would be needed from elsewhere in TfL. At this stage the
complaint will be passed on to the appropriate authority within TfL (and copied to CoW for
information) to consider and provide a further response.
If the complainant is still not satisfied, the complaint will be passed on to a nominated City of
Westminster officer (CoW to confirm) to consider and make a recommendation as to the
resolution.
