Augercast piles were originally considered for support of the new building. However, Menard provided an economical and time-saving solution with CMCs. Menard’s solution included 759 elements installed to an average depth of 34 ft and a maximum depth of 39 ft. Some CMCs were reinforced to account for lateral loads and bending moments.
The design provided for 1 in of post-construction settlement with less than a ½-in of differential settlement, meeting the performance criteria of the new, multi-use development. Two load tests were performed to confirm the capacity of the CMCs both in compression and tension.
The schedule for this project was accelerated, in large part, because Menard employed pre-drilling to penetrate the compacted, placed fill.
Because work was done in an urban setting, often during business hours, noise, vibration and general impact from construction had to be kept to a minimum. Menard deftly navigated through these challenges, successfully meeting the client’s requirements for quality, safety and schedule and allowing the client to eliminate augercast piles and realize significant savings in concrete by using spread footings in lieu of pile caps.
