This project, located on Fourth Street in the downtown core of Calgary, consisted of a tied-back continuous caisson wall. The caisson wall provided zero ground loss and minimal water infiltration, an important feature in the high density area of downtown. HCM was able to call upon experience from similar successful past projects, such as the installation of a tied-back continuous caisson wall for the new Mustard Seed Building on Tenth Avenue and Centre Street S.E., to ensure a successful project.
The system was designed for a maximum excavation of approximately 8.5 meters below grade at the north portion of the site and 10 meters below grade at the south portion of the site. This resulted in an approximate total area of 13,100 square feet of shoring required.
This project is another example of HCM’s ability to work with a General Contractor to execute a successful shoring project with a tight schedule and budget.
