Description:
Ground Conditions:
Solution:
Menard provided an economical and timesaving solution by installing 2,181 CMCs in multiple phases to an average depth of 15 ft and a maximum depth of 40 ft. The design provided for 3 in of post-construction settlement, meeting the performance criteria of the new roadway.
A unique aspect of the project was that it passed through a broad, flat wetland called the Lily Cache Slough. The General Contractor deployed dewatering pumps throughout the site to establish a sufficient working platform. For Menard, it relied on previous experience with IDOT for its CMC rigid inclusion, work platform and load transfer platform designs to address concerns pertaining to the wetland and its potential effects. The site work area was very tight and access and equipment movement was limited.
Menard has completed several projects for IDOT in the last 10 years.
