Project Description:
Foundation column loads for this mixed use tower ranged from 200 kips to 11,000 kips, requiring a mix of drilled minipiles (DMPs) and load bearing elements (LBEs) with bedrock embedments of up to 14 in hard rock. Foundation elements were constructed from an existing mat foundation 15 below street grade. A thick layer of fill and poorly graded sand combined with a high water table made digging conditions particularly challenging. Pretrenching was performed to replace the unstable near surface soils with engineered fill and a 5 steel guide wall was fabricated to maintain the slurry level above the high groundwater table. An historic amount of snow fall during construction made this project one to remember.
