A major civil engineering project

Tottenham Court Road is benefiting from major transport investment, including a new crossrail station, a rebuilt London Undergournd station and a number of other projects aimed at dramatically improving one of the most congested parts of London’s transport network.


A global monitoring solution

This major civil engineering work demands a rigorous regime of manual and automated monitoring. Challenges include high densities of pedestrian and vehicular movements at surface level, an existing, active sub-surface rail hub with numerous rail infrastructure interfaces, escalator barrels and walkways, existing utilities, including gas, water, electricity and a Victorian sewer system, that require protection. Grade 1 listed buildings adjacent to the site within the settlement zone include The House of St Barnabas and St Patrick’s Church. These difficulties must be overcome whilst complying with local authority environmental restrictions on a site that straddles both Westminster and Camden councils.

Sixense, having successfully completed two years of forward baseline monitoring on the project, have been appointed to provide a full monitoring service including procurement, installation and configuration, with ongoing management of the existing systems and coordination of manual surveyor teams to provide primary and secondary control during the construction phase.

Careful consideration of the system design, in coordination with the client, has resulted in a series of optimisations to the monitoring solution which will generate cost savings for the client as well as improvements in the level of observation available on the instrumented structures and statistically improve health and safety.
