5,720 lm of CMC for a total of 1,067 units
Project description
The project consists of seven buildings including main street retail facing Na’a Drive with residential above. Behind the main street, a supermarket is being built and additional commercial buildings. The project will bring much needed residential and commercial options to Trinity Hills and the surrounding communities.
Ground conditions
The soil in the project area consist of up varying thickness (0.9 to 9.5 m) of fill soils (generally silty clay and silt soils) overlying the native soil which consists of layers of silt and silty clay soils. The fill soils were predominantly encountered at the north end of the site.
Solution
Fill soils at the building locations did not provide sufficient bearing capacity and raised concerns of significant settlement of the footings founded at these levels. Additionally, the varying thicknesses of fill soils may have resulted in differential settlement. As a consequence, Menard recommended the installation of CMCs below all the footings within the fill area. CMCs would be installed through the fill soils and anchored in the native soils below.
