Shotcrete, Underpinning

Dufferin Mall Pedestrian Tunnel

This renovation project includes the challenge of constructing a 10ft wide by 12ft deep pedestrian tunnel inside an active mall. HCM together with RWH Engineering proposed an innovative design and construction process to accomplish this endeavor with very limited working space and tricky access issues. The construction involves:

• Shotcrete shoring to allow for vertical excavation of the tunnel area

• Bob Cat mounted TEI drill for the installation of tie backs

• Removal of excavated material via narrow stairwells and utility corridors

• Supply of materials and tools via narrow stairwells and utility corridors

In addition, HCM’s scope of work includes increasing the depth of an existing elevator pit, building underpinning, exterior stair concrete footings and retaining walls.
