Fraser River Tunnel

The Fraser River Tunnel Project (FRTP) is a new, state-of-the-art, toll-free, eight-lane immersed tube tunnel (ITT) in the Fraser River, British Columbia, connecting to cut-and-cover tunnels with technical buildings, open portals, then extending to a new Deas Slough Bridge.

The FRTP will provide a key transportation link between communities, reduce travel time, improve transportation safety, and deliver improved transit options with a dedicated transit lane and a multi-use path (MUP) for pedestrians and cyclists. The new ITT will replace the existing George Massey Tunnel and support enhanced goods and people movement capacities in Metro Vancouver to support ongoing economic growth in the region. The innovative and advanced design solution of the ITT aims to minimize impacts on the environment with sustainable construction practices, while also maintaining the navigational clearances of the Fraser River.

Ingerop and Rendel are supporting the Cross Fraser Partnership during the Design Early Work Agreement (DEWA) phase of the FRTP by performing the independent Category 3 Checking and Certification on the engineering design of the major structures, which includes:

• The new tunnel crossing permanent structures (immersed tube tunnel, cut-and-cover tunnel and ramps, technical buildings, utilities, and MUP structures that are attached to the tunnel ramps).
• Assessment of the existing George Massey Tunnel during new ITT construction.
• New Deas Slough Bridge and approaches.
• All retaining walls with tie-back anchoring systems.

In addition to the structures outlined above, Ingerop and Rendel also provide expert review on the following packages:

1. Fraser River Hydraulic Management plan
2. Fraser River Hydrotechnical design report
3. Deas Slough Hydrotechnical design report
4. Crescent Slough Hydrotechnical design report
