HC Matcon - Twinning of the West Trunk Sanitary Sewer

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.

Twinning of the West Trunk Sanitary Sewer - Caissons

Credit Valley Hospital

Credit Valley Hospital

Alternative to Save Time and Money

The Credit Valley Hospital in Mississauga, Ontario is undergoing a massive expansion and renovation. HC Matcon was brought in to undertake the shoring, underpinning, and caissons for this construction. The majority of the work included the drilling and installation of 222 concrete caissons, ranging between 24- and 84-inches in diameter. The original design required concrete-encased steel beams and conventional timber-lagged shoring adjacent to the operating hospital for support of the existing building and excavation. HC Matcon proposed an alternate to use vertical micropiles and shotcrete shoring in lieu of the above, which resulted in less disruption to the functioning hospital. The acceptance of this proposal also allowed a savings in cost and schedule time for the general contractor and owner. HC Matcon is able to overcome challenges while working with all parties involved to add value and cost savings to a project.
