Caissons, Shotcrete

A Design-Build Solution

The Scarborough Hospital was adding a new Critical Care Centre in the courtyard surrounded on all sides by existing hospital structures.

HC Matcon’s scope of work included:

excavation of the new building foundation on pad footings
permanent shotcrete underpinning system to support surrounding structures
soldier pile and lagging wall to support a pedestrian walkway adjacent to pad footings and service manholes
demolition of service tunnels while maintaining operation and maintenance access for emergency services and hydro caissons to support new canopies and additions to existing structures.

At various points during construction, HC Matcon has been required to provide innovative design-build solutions to accommodate changes to the original design.
