Airport Road Storm Sewer from International Centre to Derry Road
This project included the construction of a curved microtunnel tunnel drive that was 323m long. The microtunnel excavation diameter was 1.575m; the curve radius was 1,150m; and the microtunnel RCP installed had an internal diameter of 1.2m. The purpose of the tunnel was for a storm sewer. Along with the tunnel, two (2) shafts were constructed through varying ground conditions such as gravel, sand, clay and silty clay under water pressure.
