Instrumentation and Monitoring Close Out Reports

This dataset includes ground movement monitoring close-out reports prepared by Crossrail contractors during tunnelling. These are shared with the aim of assisting better understanding of soil structure interaction and control for future tunnelling projects in London ground conditions.

The Thinner Pen Paradox

Proving that something doesn’t exist can be as important as proving that something does exist and the example of perceived noise in monitoring systems can fall into both scenarios. Cities all over the world are growing and one of the greatest challenges facing us as engineers is how to increase [...]

Control Narratives for Heating Ventilation and Air Conditioning System for Stations Shafts and Portals

This paper provides a unique ‘one-stop-shop’ for generic control operating narratives for heating, ventilation and air conditioning systems that could be designed in a station, shaft or portal. It describes the minimum requirements for the operation and monitoring of the building services instal [...]

In Situ Stress Strain Measurements at Tottenham Court Road Platform Tunnel

The redevelopment of Tottenham Court Road Underground Station started in 2011 as part of the Tube Upgrade Plan to improve and increase the capacity of the existing facility. The plan is to upgrade the station by 2016 to meet an estimated demand of more than 200,000 journeys per day once Crossrail is [...]

Lessons learnt from the installation of field instrumentation to monitor ground response to tunnelling

Imperial College in collaboration with Crossrail are performing field monitoring research to investigate the effect of tunnelling in London Clay. This is part of an EPSRC-funded research project investigating how tunnelling affects existing tunnels with segmental cast iron linings. The field researc [...]

Field measurement by fully grouted vibrating wire piezometers

Subsurface instrumentation was installed at a field monitoring site in Hyde Park and bordering Bayswater Road for measuring the ground responses to Crossrail tunnelling near Lancaster Gate. Prior to the passage of the tunnel boring machines, pore water pressures were measured, both in the “greenfi [...]

Data management, analysis and visualisation on Crossrail Drive X Western Tunnels

Crossrail Drive X Western Tunnels extend from Westbourne Park to Farringdon Station. With the TBM and SCL contracts working under the most expensive real estate in the world, the safeguarding of assets is paramount for safety and stakeholder’s assurance. The management of instrumentation data from [...]
