The complexities of setting up Crossrail’s large monitoring programme
By Steve Thurgood MCInstCES, Monitoring Solutions Consultant at SCCS.
In July 2011, Costain and Skanska working as a joint venture (CSJV) were awarded Crossrail contract C405 to complete the main civil engineering works for the new Crossrail station at Paddington. The station will be built underground below Eastbourne Terrace and adjacent to the southwestern elevation of the existing mainline terminus station.
The new station construction area is surrounded by English Heritage grade I listed buildings which form the existing station along one side and modern office buildings on the other. The entire area is in a densely built up zone of the centre of London with mixed commercial and residential buildings.
The respective heads of the engineering surveying departments for the parent companies reviewed the construction sequencing and methodology, and decided to undertake all of the engineering surveying for the construction phases. The team also decided that the parent companies would install, run, operate and maintain large parts of the instrumentation and monitoring (I&M) schemes that were required in the client specification, rather than subcontracting the works out to an I&M specialist.
