Underground Lunch & Learn

February 21, 2018 @ 12:00 pm - 1:00 pm

The Billy Bishop City Airport Pedestrian Tunnel in Toronto is the first known underwater pedestrian tunnel to an airport facility in the world. It was constructed in the thinly horizontally bedded Georgian Bay Shale formation characteristic of Southern Ontario, and employed a unique pre- support technique comprised of seven 1.85m diameter interlocking horizontal secant drift bores, each sequentially drilled by tunnel boring machines and backfilled with mass concrete. This presentation will describe the key aspects of the design and construction associated with this groundbreaking tunnel project.
