Twinning Of The West Trunk Sanitary Sewer

This project includes the installation of a deep trunk sanitary sewer within bedrock under Erin Mills Parkway in Mississauga. HCM together with RWH Engineering proposed an innovative and economical design and construction process for shoring the manholes and access shafts using caisson compression rings. Challenges that had to be dealt with included designing the compression ring to withstand large uneven surcharges caused by a close embankment in addition to large surface loading by a crane. To ensure the safety of the shoring system RWH Engineering is providing precession monitoring utilizing inclinometers.
