Approximate Key Quantities: Controlled Modulus Columns (CMC)® - 11,000 EA.
Description:
Ground Conditions:
Solution:
More than 6,000 Controlled Modulus Column (CMC)® rigid inclusions were installed to support six MSE walls in the first phase of the project and nearly 5,000 were installed to support new embankments, eight MSE walls and interim ramps in the second phase. The CMC rigid inclusion ground improvement successfully supported various loading criteria, including embankments, MSE Walls and roadways while meeting the project’s specified settlement, bearing, sliding and external stability requirements. Despite difficult conditions – which included tight work areas, varying working elevations and proximity to high-speed traffic on roadways traversed by nearly 250,000 vehicles daily – all work was performed safely. The project was completed as designed and met all NJDOT requirements for safety, quality and schedule.
