AMI Consulting Engineers, PA provided structural, civil, environmental and marine engineering for the 84,500-square foot Pier B Resort located on the waterfront in Duluth, MN. This project was a Brownfield Redevelopment of a historic industrial pier that included a turn of the century lime kiln and warehouse as well as a mid-1900’s bulk dry cement storage and distributor. The resort includes 140 room hotel, banquet center, restaurant and bar; outdoor multilevel decks and waterfront patio, pool, outdoor whirlpool; new sheet pile wall (variable mooring sizes), transient marina, boat & canoe launch, and a new sliding bridge that connects parks, trails and event centers. Although still under construction, the Pier B Resort has transformed the iconic industrial pier into a “must see” destination with scenic views of the Duluth-Superior Harbor and Aerial Lift Bridge.

AMI provided structural engineering for a four-story hotel, civil and storm water design, utilities, marine civil engineering, retractable bridge design, land and marine survey, underwater inspections, demolition, construction oversight/inspection, wave run-up studies, environmental remediation and capping of contaminated soil, geotechnical, capping and shallowing of legacy contaminants in the sediment of Slip 2, and the design of critical habitat improvements. 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. Project permitting & environmental cleanup at the site was extensive, working with local, state and federal agencies; regulatory permits, concurrence and closures related to the design, construction, environmental, historic preservation of the site. The project is on schedule for completion in June of 2016.
