AMI Consulting Engineers, P.A. was chosen as the design team lead to provide full engineering services for the Hallett Dock 8 project. These services included an initial as-built investigation for 2,500 feet of existing wood crib & wake field dock, complete bathymetric/hydrographic survey for dredge planning to the USACE Channel, underwater inspections, and survey for project baselines & layout. AMI assisted the City of Superior and Hallett Dock Company with construction estimates and initial site layouts and plans to obtain Wisconsin Harbor Assistance Grant funding. The complete analysis of existing dock structures on site led to a unique design and cut the overall cost of the project by utilizing the old gantry crane foundation as the new anchor wall. The total design of the project included 850 feet of new steel sheet pile dock wall, marine coatings, double channel wale, steel tie rod anchor system, steel pile cap, steel safety ladders, wood fenders (rub rails) and increased mooring capacity and flexibility by installing new larger bollards and foundations.
To meet the Wisconsin and City of Superior grant guidelines, AMI provided complete construction documents & specifications, obtained all DNR, ACOE and City permits and prepared documents for the City of Superior for the public bid process. AMI provided final underwater inspections of the as-built conditions, pre & post dredge surveys and construction management throughout the entire project. The close monitoring of the project insured the contractor stayed on schedule and completed the project according to plans. AMI reviewed and approved all payment requests and provided complete construction closeout at the completion and acceptance of the final product.
