NORDIC Group, Inc. provided underwater inspections, demolition, earthwork, construction oversight/inspection, and capping of contaminated soil. Capping of legacy contaminants in Slip 2 involved the development of a public and private partnership that included the developer, the MPCA, Army Corps of Engineers and the Minnesota MDNR. The capping project placed a minimum of 2.8 feet of clean dredge sediments across the 2+ acre slip. The dredge material used was pre-screened for structural and chemical characteristics and obtained from the Army Corps of Engineers dredging operations. An additional 7 feet of dredge material was placed above the cap to provide structural support to the aging pier walls and to provide protected shallow water habitat.
