With a projected cost of GBP 6.8 billion, the Lower Thames Crossing (LTC) is England’s single largest road investment project since the completion of the M25 more than 30 years ago. The project is unprecedented in size and scale, making it the longest road tunnel in the UK. At 16 meters in diameter, it is also one of the largest diameter bored tunnels in the world.
LTC requires enormous geological and geotechnical investigation along the entire route, both north and south of the River Thames as well as under it. Key areas of interest include a protected wetland in Kent, boring the tunnel under the river, and historical land development in the north. The comprehensive and complex schedule of tests in Phase 2 includes investigating more than 700 locations with over 400 boreholes, some of which will be up to 100 meters deep. The team will also perform nine pump tests and around 85 trial pits and geophysical surveys, all of which require seamless information management. To maintain the schedule on the LTC, a large set of big data, consisting of historical, current, and draft data was developed from numerous phases of ground investigation across a large geographic area. The project team needs to access the data and share it across the multidiscipline project team, as well as with external parties.
Read the case study to see how this joint venture between LTC and CASCADE leveraged OpenGround to allow BIM teams, suppliers, partners, and clients easy access to project data so they could be actively involved in any decision processes.
