Sarens Successfully Executes TBM Removal for Annacis Water Supply Tunnel Project in Canada

Sarens recently completed the challenging task of removing the tunnel boring machine (TBM) from the Annacis Water Supply Tunnel Project in New Westminster, British Columbia. The operation was performed on behalf of Traylor Aecon, as part of a major infrastructure project designed to increase the reliability and capacity of the water supply system and secure clean drinking water for more than 2,7 million residents.

Precision Planning and Execution

The removal of the TBM cutting head, weighing approximately 250000 lbs, was carried out at a radius of around 25 feet. The project required careful planning due to the confined jobsite and surrounding traffic conditions.

During the planning phase, Sarens’ engineers addressed critical points such as crane line length, capacity calculations, and engineered lift points on the TBM. For this operation, Sarens deployed its LTM 1400 crane (main boom only), selected specifically for its capacity and reliability in such constrained working environments.

Equipment and Logistics

The crane and necessary counterweights were transported from Surrey to New Westminster, requiring 4–5 trucks and around 40 minutes of travel time. On-site setup of the equipment took 8 hours, after which Sarens’ crew of four specialists executed the lift with precision.

Despite the confined space and logistical challenges of the site, the team worked seamlessly to perform the operation safely and efficiently, underscoring Sarens’ reputation for technical expertise and operational excellence.

Supporting Critical Infrastructure

By successfully completing this removal, Sarens has contributed to a project of vital importance for the region: ensuring a stable, long-term water supply to millions of people across British Columbia.

With decades of experience, a global fleet of high-capacity equipment, and a proven track record of safe, precise execution, Sarens continues to demonstrate why it is trusted to handle the world’s most challenging lifting and transport projects.
