About this file
This document package includes plans and specifications for a federal solicitation seeking pipeline maintenance dredging services. The U.S. Army Corps of Engineers, Portland District is issuing Invitation for Bids W9127N20B0025 to dredge the Coquille Bandon Boat Basin to a required pay depth of 13 feet below mean lower low water by removing accumulated sediments from the entrance channel, access channel, and areas adjacent to docks and floats. Dredged materials may be placed in a designated in-water placement site approximately 100 feet in diameter located near the dredging areas. The work must be completed between the award date of June 12, 2020 and November 30, 2020. The existing project maintains an entrance channel 13 feet deep and 100 feet wide for 300 feet and an access channel 13 feet deep and 50 feet wide for 500 feet to provide access to docks and floats from the Coquille River.
