Tunnels & Tunnelling – C701

The Crossrail project is currently the biggest tunnelling project in Europe with around 21km of the total 118km route contained within newly bored tunnels. ITM Monitoring was contracted as Principle Contractor by Crossrail to provide monitoring systems for the various third party assets within the central section of the route.

Summary of the Works

  • Client – Crossrail
  • Contract name – Crossrail Contract C701
  • Approx. Value – £26,000,000
  • Start Date – March 2010
  • Completion Date – December 2013

Widely regarded as the largest monitoring contract ever awarded, ITM Monitoring installed and maintained over 30,000 sensors across 15 separate sites in Central London.

In total, ITM Monitoring successfully installed close to 1,500 Electrolevel Beams, 25 Bassett Convergence Systems, 200 Tilt Sensors and over 280 Robotic Total Stations (RTS). Many of the RTS were designed to operate within large networks (30+ instruments) with the data processed via ITM Monitoring’s own Star*Adjust Least Squared Adjustment programme. This allowed us to provide accurate readings on each of the 25,000 3D geodetic prisms on an hourly basis.

The majority of the monitoring systems were logged in near real-time and data was presented back on a bespoke software package known as the Underground Construction Information Management System (or UCIMS). This GIS based system was designed for Crossrail and can handle data from the numerous construction contracts situated across the Crossrail route.
