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
Medicine Hat Regional Hospital – New Tower Expansion The Government of Alberta and Alberta Health Services (AHS) have broken ground on this project, which will renovate and expand the hospital to improve patient services and reduce wait times. When complete, the $200-million redevelopment will expand available ambulatory care space and will allow more space for
Increased Safety: We Used Horizontal H-Piles This project is a part of a large upgrade to the Currie Reservoir in southwest Calgary, Alberta. The project included the installation of a caisson wall as well as horizontal shoring and underpinning. The purpose of the installation of the caisson wall was to provide support for the existing
Horizontal Underpinning This project consisted of an interlocking secant pile wall, combined with horizontal underpinning to accommodate a new connection to a pump house at the Currie reservoir in Calgary. The interlocking secant pile wall (caisson wall) allows for an accelerated construction schedule as it eliminates the ground loss that is present with the use
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
Zero Ground Loss This project followed shortly after finishing the Taylor Family Digital Library project, which was in close proximity to this site on the same campus. Design considerations for the foundations were almost identical to the previous project, with the installation of approximately 175 cast-in-place belled piles. Again, this new building was a result
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.
