Description:
Ground Conditions:
Solution:
Before CMC rigid inclusion installation could begin, the client installed sheet piles along the length of the causeway for shoring for the MSE walls and working pad. Menard crews then began installing CMC rigid inclusions, and the general contractor followed behind Menard rigs building the MSE walls and placing fill on top of the cured columns. Menard added reinforced steel bars in some of the CMC rigid inclusions, and designed steel reinforcement in the fill to reduce lateral movement of the MSE walls.
Ground improvement construction finished ahead of schedule due to the mobilization of multiple rigs, and high-level coordination between Menard crews and the general contractor. More than 4,800 CMC rigid inclusions were installed to average depths of 36 ft. At the time of construction, this was the largest CMC rigid inclusion project for the Minnesota Department of Transportation, both in quantity and dollar amount.
To support a new causeway on the site of a former bridge, Menard installed CMC rigid inclusions.
