For the forcemains, we placed +3,500 metres of twin HDPE pipe and +400 metres of gravity sewer as well as rock, earth and directional drilled bores. For the pump station, we excavated and backfilled a wet well and installed a dewatering system, building foundations, yard piping and a secant central shoring shaft 21 metres in diameter and 20 metres deep. We also protected two adjacent buildings with interlocked sheet piling, tie-backs, walers and struts.
Most large construction projects run into unforeseen circumstances. We pride ourselves on being flexible when scope needs to be adjusted. In this case, several forcemains were re-routed to avoid existing utilities, and additional erosion and sediment controls were required beyond the original project scope. We addressed these shifting requirements with flexibility, completing the project within the existing timeline.
