Engineering Solutions The Toronto Transit Commission will be purchasing all new subway cars in the near future, creating the requirement of larger maintenance carhouses. The original contract drawings employed caisson wall, soldier piles and lagging, and conventional concrete underpinning for the earthwork specifications related to our field of work. HC Matcon proposed an alternative engineered
Unique Soil Conditions The future location for this tower is located immediately adjacent to the emergency wing of the existing St. Joseph's hospital in Hamilton, Ontario. HCM is a recognized shoring contractor that will take on many challenges relating to foundation design. On this particular project, HCM took on the tasks of: shotcrete shoring caissons
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
The future Bow building, located in Calgary, Alberta Canada, is an innovation in both architectural and shoring design. At 58 stories and with a footprint of two city blocks, The Bow will be the largest building in Canada west of Toronto. It will be an impressive addition to the Calgary skyline and will serve to
Shotcrete Reduces Costs for Owner The St. Joseph's Health Centre is adding a new Our Lady of Mercy wing complete with three levels of underground parking. HC Matcon was responsible for: installing the approximately 20,000 square feet of zero clearance shotcrete and caisson wall to be used as a back form for the foundation walls.
Complex Shoring Requires Innovative Design Work on this site involved the supply and installation of caissons, underpinning, rock anchors, as well as both traditional soldier pile and lagging and shotcrete shoring systems. Shoring designs were required to incorporate work next to the existing CN passenger rail tracks and the historical heritage buildings being developed into
A Shotcrete Solution to a Difficult Problem Work to the existing Biosolids Facility required the installation of deep pits and foundations for proposed processing equipment. Due to the tight confines of the site and the proximity of exterior walls, columns and footings, the use of a traditional soldier pile and lagging system was not feasible.
Shotcrete: Low Cost and Overcoming Hillside Access Issues This 12,000 sq. ft. project involved temporary hillside shoring for a developer in Tillsonburg. The project was completed during winter months with winter protection of panels and concrete and special measures by HC Matcon designed for winter conditions. The shotcrete shoring solution was both low cost and
Overcoming Poor Soil-Bearing Capacity The Paruk Residence is a high end two story structure, located at 24 York Valley Crescent in North York, Ontario, just north of the Don River. A geotechnical investigation performed by Patriot Engineering revealed very poor soil bearing capacity, unsuitable for a slab-on-grade or strip footing foundation. The floor slab was
Toronto's First Permanent Soil Nail Wall This project involved a hillside lot and a high end home in Toronto. The installation was the first permanent soil nail wall used in Toronto. Micro piles were used to support a cantilever canopy on one level and HC Matcon completed the full excavation, shoring and footings as a
