Alternate Methods Stop Running Sands

HCM was retained to design, supply and install a complete shoring system to facilitate construction of the new St. Thomas Court House for EllisDon. Construction of the proposed shoring was initially for soldier piles and lagging with a single level of bracing using tiebacks.

The existing structures were initially designed using conventional underpinning. When excavation reached the underside of the existing structures it had been determined that soils were not what expected in the geotechnical report. The existing soil conditions were flowing wet sands and HCM was asked to provide an alternate method to the conventional underpinning.

HCM implemented a shotcrete underpinning system including positive support of the existing rubble foundation to allow us to support the structure and lateral pressure of the earth while excavation proceeded to base of the new structure.

With the assistance of RWH (an HC Group of companies) our ability to react and provide an alternate design solution allowed HCM to complete successfully the shoring and foundation works within EllisDon’s budget and schedule.

HC Matcon achieved a significant milestone on the Weston Tunnel project, allowing for the GC to accelerate the schedule and make up for project delays. HCM mobilized 5 large diameter drill rigs and in seven and a half weeks installed 311 soldier piles (12,000 linear feet) drilled into bedrock up to 60 feet deep and approximately 620 filler piles (7,000 linear feet). The work was completed with an average of 30% downtime as drilling was carried out between two operational train tracks.

The Pemberton Group is adding the luxury waterfront Bluwater Condominiums to its portfolio. The 22,000 SF area of shoring area will accommodate the construction of three eight-story buildings on the banks of Lake Ontario.

The job was tendered with numerous systems; soldier pile and lagging, caisson wall and shotcrete shoring. The excavation depth was 7.5m with soils on the site comprised of 3m of overburden underlain by shale bedrock.

HC Matcon (HCM) in conjunction with Isherwood Associates completed the shoring using shotcrete shoring. Shotcrete shoring system allowed for significant cost savings and quicker installation over a conventional shoring system.
