Mapleview Drive
The expansion of Mapleview Drive in Barrie required track protection for an existing railway overpass. HCM was retained to install a strutted piles and lagging shoring system. RWH Engineering Inc. (RWH), an HCM Group company, engaged the design responsibility for the project, resulting in significant improvements to the tendered drawings. HCM and RWH redesigned the shoring system to better suit excavation and bridge footing construction. The redesign revised the center pier shoring system from a boxed in strutted system to a tieback shoring system. This allowed better access for shoring installation, excavation, and forming.
Due to site conditions and steep slopes, HCM coordinated all drilling platforms with the GC which optimized shoring and excavation activities and maintained the project schedule. Coordination with the GC for the temporary bridge placement was paramount as track removal and temporary bridge and track installation had to occur in a time period of four days.

Significant time-saving was realized during installation by redesigninig the tendered sheet piling and driven piles close to existing tracks with an extended drilled double pile and lagging.
The work was successfully completed on time and on budget. This project exemplifies HCM’s ability to find cost-effective solutions to complex project requirements.
