Project Overview
The project involved the construction of a launch shaft into the profile of a hill beneath Eglinton Avenue in Toronto. This project represents the first phase of an $8.5-billion transit expansion program to install a Light Rail Transit system from Black Creek Drive to Scarborough Town Center.
Through a series of traffic stages, the project included the widening of the bridge over Black Creek Drive and the construction of a caisson wall to permit the excavation of a 60-metre-long x 20-metre-wide x 17-metre-deep access shaft for Tunnel Boring Machines.
During construction, we installed a temporary road deck consisting of concrete deck plates and structural steel beams to permit unhindered vehicle movements on Eglinton Avenue during the overall project.
Situated in a small footprint with restricted access, the launch shaft was modified, and construction sequences were adapted to benefit the subsequent tunnelling contractor.
