Description:
Ground Conditions:
Solution:
Work on this project was interrupted by the COVID-19 pandemic, as a nationwide lockdown was initiated one week after mobilization. Menard Group USA restarted work a week later. Driven steel piles were originally considered for foundation support. However, Menard provided an economical and time-saving solution with CMC rigid inclusions. The CMCs eliminated the need for handling and removing large amounts of spoils generally created through the process of driven steel piles. The CMCs also terminated at an average depth of 50 ft, significantly less than the predicted depth of the steel piles. Total savings for the client: Several hundred thousand dollars.
Menard’s solution included the use of 686 CMCs that were installed beneath the spread and strip footings to a maximum depth of 60 ft. The design provided for 1 in of post-construction settlement with less than a ½-in of differential settlement, meeting the performance criteria for the new building. Additionally, the design for the parking lot and courtyard provided for 2 in of post-construction settlement. Menard met the client’s requirements for quality, safety and schedule.
