Scope of Services

Value Engineering (V.E.) Team Study on this 5km long, 5.5m. diameter twin tunnel transit system. The PCC bridge structure spans the Don River. The Twin Tunnels Project (Leslie Station to Bonnington Place & Buchan Creek to Don Mills Station) was designed as twin circular tunnels from a shaft immediately west of the GO Transit line at Leslie Station to Bonnington Place, a distance of 3,250 meters.

V.E. team members, selected members of the TTC and design team performed a site visit in order to more fully comprehend the project scope and complexities of the construction phasing due to the proximity to a college, a hospital, and a shopping mall. Proposals totaling $18,216,560 in savings were recommended by the V.E. team.
