The project provided reinforced concrete bases for two autotransformers and switchgear mast base stations.
The switching station will provide traction power for Elizabeth line trains.
Works, part of projects C644 and C610, included
- Site clearance including excavations and mass earthworks
- Temporary works design and management
- Deep, surface and track drainage
- Earthing mat installation
- Ducting, troughing and cable route management
- Reinforced concrete foundations and retaining walls
- Kerbing, surfacing and access roads, marking and pavement drainage
- Electrified palisade fencing, Network Rail boundary fencing and Armco barriers
- UTX chamber installation
- Track formation and ballast installation
To overcome se
vere space restrictions, the team devised an innovative design for a retaining wall, braced solely within the small site. This allowed them to retain the Network Rail fencing beside the site.
The project team used a proprietory formwork system to reduce pours for the main retaining wall installation works from 33 to 12. They planned deliveries and concrete pours carefully to maintain ongoing access to the Network Rail depot next to the works.
Site security was strictly maintained, with 24-hour CCTV, to eliminate the risk of vandalism.
Compliments
“The works at Westbourne Park have been complicated by the site interfaces with buried services, preparations for specialist deliveries for other projects, and partial works completion from previous works. VGC’s site team has overcome these challenges and presents a good quality of workmanship.”
Electrical works manager – ATC
Site managers Donal McCarthy and Carlos Allca received Crossrail values awards for collaboration.
“Donal McCarthy and Carlos Allca have taken on works left by a previous contractor and vastly improved on the quality of the works, and delivered on their promises. Despite a very tight schedule and a restrictive site they have never compromised on safety and have ensured the team are empowered to speak up.
“They encourage good communication and this is reflected in the engagement Crossrail has with the people on site. They have coordinated works with other contractors. We have jointly spoken to all local businesses … in the six months on site nothing has been an issue with the community.
“They are open and honest, never over-report and tell it like it is.”
