The new Crossrail Train Depot built by Taylor Woodrow at Old Oak Common, includes construction of new structures and multiple additional sidings to assist in the maintenance and operation of Transport for London’s new Elizabeth Line fleet of trains. PC Monitoring, Plowman Craven’s structural monitoring arm, has been selected to provide a track and structural monitoring system to record any movement of the sensitive assets bordering the site.
A monitoring system was required which would meet strict Network Rail standards and measurement parameters. The management of the project was also a core consideration and PC Monitoring was able to work with Network Rail and Taylor Woodrow to provide the documents and permits required to access, install and monitor the scheme.
The installed system encompassed track prisms mounted along both running rails, allowing the core parameters of cant, twist and displacement to be recorded. This was supplemented by structural prisms on the retaining walls adjacent to the canal to provide stakeholders with an indication of any movement.
