About this file

Written by GovTribe AI · Dec 27, 2023

This solicitation package includes plans and specifications for the 2022 OR/WA Clamshell Maintenance Dredging project. The work involves dredging of federal navigation channels in Oregon and Washington using clamshell dredging methods. Locations include Port Orford, Baker Bay, Chinook River, and Skipanon River. The solicitation number is W9127N22B0011 and was issued by the US Army Corps of Engineers Portland District. Bids are due on an unspecified date, and the contract is to be awarded in 2022. The package provides layout drawings and cross sections of dredge and disposal areas, depth curves, and placement site details for four identified sites. Coordinates for dredge and disposal areas are included, along with survey dates. Specifications address dredging depths and tolerances determined based on pre-dredge surveys.
