Site work for a water / sewer project in Duluth, Minnesota. Completed plans call for site work for a water / sewer project.

This project involves maintenance dredging in the Duluth-Superior Federal navigation channel located along the border of Wisconsin and Minnesota. The Contractor will be required to mobilize a dredge to the Duluth-Superior channel and perform mechanical dredging within the channel. All dredged material will be placed at the Erie Pier Confined Disposal Facility (CDF). The Contractor must have the equipment and ability to perform in-water mechanical dredging to the required depths, to transport and place the dredged material at Eire Pier. Dredging will be required within the following areas: o Duluth Harbor Basin along the westerly channel limits o East Gate Basin near Rices Point o Superior Front Channel along the southwesterly channel limits o Channel near Hog Island o Howard's Bay near the I-535 bridge The contract also includes option tasks to perform additional dredging within the East Gate Basin along the easterly channel limits. The required dredging depths for the base will be approximately 27' to 28' below low water datum (LWD) depending on the location within the harbor. Dredging depths for the options will be approximately 10' below LWD. The material is expected to be a mix of sand and fines, with the potential of minor debris typical in an active harbor. The quantity of material to be dredged will be approximately 51,000 cubic yards (base contract) and may total approximately 85,200 including approximately 35,000 cubic yards under option tasks. The anticipated period of performance for dredging is 17 July 2023 through 15 October 2023. The Contractor would then demobilize when dredging is complete.
