Thames Tideway Tunnel
Thames Tideway Tunnel or London’s ‘super sewer’ is a 25km tunnel bored underground to improve the quality of water in the river running through the heart of the city, benefiting millions of residents and visitors.
BAM Nuttall, as part of BMB, is delivering the West section, 6.9km, tunnelling through London clay from two shafts.
The project uses 3D and 4D building information modelling technology (BIM) to improve planning and delivery. By identifying and anticipating constrains and challenges, through the use of virtual reality and immersive 3D modelling, teams have achieved higher safety levels and more predictable performance.
An innovative planned preventive maintenance (PPM) scheme for the tunnel boring machines (TBM) allows for easier and faster data collection during the operation. Using electronic sensors, the system collects data through portable devices located in the TBM. Operated by maintenance teams, it’s integrated with TIRA web based system, allowing them to see results on site.
The team has replaced the entire paper-based plant checking system with web-based digital Field 360 systems, using iPads to capture plant inspection data on site.
