The tunnel will be London’s deepest ever – being 75 meters down at its lowest point. With the myriad underground structures beneath the city, the project team must avoid the many other tunnels and conduits used for rail, road, electricity, gas, and communications infrastructure. Moreover, it must prevent ground settlement from damaging the surrounding buildings. Settlement analysis will be conducted wherever the tunnel passes beneath or close to buildings and other structures, and mitigation efforts will be implemented as required.

The team is using InRoads to manage horizontal, vertical, and 3D alignments of both the main tunnel and various connection tunnels. In addition, it is implementing gINT to manage the huge amounts of geotechnical data needed for the tunnel, as its prior software was unable to handle the necessary quantity of data.

Delivering the Right Information to the Right People

To meet the needs of various audiences and stakeholders, the Thames Tideway Tunnel project team will employ easy-to-use web tools to provide the required information to project decision makers. Moreover, Bentley Navigator will supply web-based access to 3D models for design review and clash detection. In addition, Bentley’s ProjectWise InterPlot will be used for publishing both web-based document sets and paper construction documents. The goal is to make all project information available to the entire team on the web.
