Telus Sky tower

,

The Telus Sky tower will be the 3rd tallest building in Calgary with the deepest basement excavation in western Canada. HCM Group took on the challenge of creating a shoring system suitable for the 30m excavation. RWH designed the shoring system with an 11m deep perched secant wall and shotcrete was used in the bedrock

HCM Group - Sage Condominiums: Phase II

Sage Condominiums: Phase II

The Sage Condominium in Waterloo required an innovative shoring system that could facilitate a 10 meter foundation depth while working within encroachment restrictions. HCM implemented a soldier pile and shotcrete shoring system which utilized a single row of highly loaded rakers, designed by RWH Engineering Inc. (RWH). The use of bypass shotcrete over a traditional

HCM Group - K2 Condominiums

K2 Condominiums

This development on King Street in Waterloo required approximately 15,000 SF of shoring for two levels of underground parking. RWH Engineering Inc. (RWH) designed a piles and lagging shoring system with rakers to reach depths up to 9 meters. Wet fine sands required careful excavation and lagging in small lifts to ensure no ground loss

65 Lillian Street Condominium Building

Value Engineering Work on this jobsite included the excavation support system for a new condominium building located on 65 Lillian Street in Toronto, Ontario. HC Matcon used soldier piles and shotcrete lagging shoring (SPLS) with soil nails to support the excavation of an approximately 30-foot deep underground parking garage. One challenge of this project was

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

St. Catharine’s Exit Shaft

St. Catharine’s Exit Shaft

This project consisted of an exit shaft that was completed in one day and consisted of an innovative drilled shaft option completed at a fraction of the cost of the entry shaft constructed which took several weeks. The top 12-15′ of soil was a soft clay requiring a top liner for soil retention. HCM provided Baiocco

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

Alloa Feedermain

This project involved installation of 3 watertight caisson wall shafts. Two rectangular secant pile wall shaft approx 12m deep and one 6m diameter compression ring shaft approx 7m deep. In order to achieve the tight tolerance needed to ensure the shafts were in fact watertight the use of a guide wall was implemented. The guide

Great Lakes Copper Plant

Great Lakes Copper Plant

Great Lakes Copper Plant The Great Lakes Copper Plant in London, Ontario, posed a technical challenge in shotcrete shoring. HC Matcon helped to facilitate the installation of a new copper roll press. The shoring was completed inside a fully operational copper plant at night and on weekends. Special care was taken to ensure dust and
