VGC was contracted to build a barrier between the railway and adjoining houses at Shenfield, as part of the Crossrail Anglia project.
The barrier will reduce the impact of sound and light from the railway.
We installed an acoustic barrier 3m high and 250m long.
The timber used for the barrier has been specially treated to absorb sound and reduce noise pollution; it also blocks lights coming from the train stabling yard at night.
The project was managed from a site office at the aptly named Officers Meadow. Access to the site was through the station car park and along the railway. Our teams used road-rail vehicles and a long-reach hiab to overcome challenges of restricted access alongside the track.
During overnight possessions, the team excavated foundations for the barrier using road rail vehicles to deliver materials. They erected steel posts using scaffolding supports. A concrete pump was used to deliver concrete along 400m of pipe to the foundations.
They bolted vertical timber supports to the steel posts, and fixed timber acoustic boards to the structure.
The horizontal timber boards have tongue and groove joints, creating a tight seal which limits the transmission of sound and light.
This project is part of the eight-mile section of Crossrail Anglia from Manor Park, east London, to Gidea Park in Essex. The project being undertaken by Costain involves track renewals, installing overhead line equipment, turn back facilities, and station improvements at eight stations along the route.
