Project Overview
This development involves the construction of a 4-storey plus basement addition to the Innis College building at the University of Toronto. Menard Canada was contracted by Urbacon to install Controlled Modulus Columns (CMCs) below the structure’s foundations.
Selected Techniques
Controlled Modulus Columns (CMCs)
Treatment Area
183 Unit(s) CMCs
Installation de colonnes à module contrôlé (CMC) pour le projet d’agrandissement de l’Innis College de l’Université de Toronto à Toronto, en Ontario.
Ground Conditions
The site is challenged by fill extending up to 2.6 m below ground surface, underlain by stiff silty clay. Groundwater was encountered at a depth of approximately 3 m below ground surface.
Menard Canada Solution
Controlled Modulus Columns were selected as a ground improvement solution to provide the required bearing capacity and settlement control for the foundations of the proposed structure. CMCs were used to achieve a bearing capacity of up to 250 kPa SLS / 375 kPa ULS, a maximum post-construction settlement of 25 mm total, and a maximum differential settlement of 19 mm between footings.
