The scope of works will entail building new stabling roads. This will require additional track, new Switch

and Crossings (S&C) units, platforms, walkways, lighting, communications and signalling. Therefore the

scope encompasses all of the disciplines below and is divided into the following packages of works:

Civils;

Communications Systems;

Signalling;

Permanent Way;

Electrical Traction Equipment;

Electrical Services & Depot Equipment; and

Mechanical Services.

The contract let on a build only basis as detailed design completed separately and prior the

commencement of this works.

Docklands Light Railway (DLR) is procuring 33 new fixed formation trains as part of its Rolling Stock

Replacement Programme (RSRP) to replace the life expired B90/92 fleet and 10 new fixed formation trains.

The new trains are needed to meet the service requirements for future growth and development in the

Royal Docks area. In order to facilitate these new trains, the maintenance and stabling capacity of the

Beckton Depot (located in London) will need to be upgraded.

The works required to be undertaken;

Area 1: Installation of surface water drainage, Train Wash with road access and associated Pump Room.

Completion of a retaining wall will be required, along with an attenuation tank up to 100m3. Installation of

a security access fence to the site boundary.A new ATO Test Track with a level crossing,. Attenuation will

be required within this area and current drainage calculations suggest this will not be larger than 100m3.

Also, Rolling Stock AVI (Automatic Vehicle Inspection) is required to be housed alongside the train wash.

As previously stated the scope includes installation

of a retaining wall r construction of the eastern section of the retaining wall will need to take place

following the decommissioning of the current test track.

Area 2: Installation of hoarding, decommission of existing roads D, E and F, installation of drainage and

associated services. To achieve this, decommissioning existing roads D, E and F will be required, prior to

the installation of drainage and associated services to support the works.

Area 1/2 Combined: Installation, test and commission of ballasted track and associated access platforms

for new roads BA – BK inclusive; all roads to be signalled and controlled as per design.

To achieve this, installation, test and commissioning of 11no stabling roads. The disciplines included are:

i. Track (including associated ballast and tamping)

ii. Civils (including platforms)

The works also include the installation, test and commissioning of the services to allow the use of the

stabling roads. The disciplines include, but are not limited to:

i. Power (LV and traction)

ii. Lighting (including columns)

iii. Water provision for cleaning

iv. CRMS

v. 2no REBs (Relocatable Equipment Buildings) to house points and points heating control.

Train delivery roads will need to be provided to enable the delivery of the new rolling stock.
