Matcon Civil was the Civil and Shoring subcontractor on Fraser Health’s Surrey Memorial Hospital Critical Care Tower project. Matcon Civil’s work included demolition of some existing facilities, installation of all storm, sanitary and water services for the new tower, and the parking basement excavation works.
The basement excavation included a 4,000m2 caisson shoring wall, almost 100,000m3 of excavation, detailed footing excavation, and 1,000lm of steel piles. The work was particularly challenging as Matcon Civil was required to work between and immediately adjacent to active hospital buildings that had a maximum allowable settlement of 2mm throughout building envelope area.
The tower was constructed in an area of poor soils that had previously only supported low-rise buildings. Throughout the excavation Matcon Civil’s crews encountered hazardous asbestos cement pipe, abandoned fuel tanks, and several previously unknown services running in various directions. Matcon Civil was able to work with the Prime Contractor and other trades on site to overcome these and other challenges to successfully complete the project within the difficult site constraints.
