Portland— The U.S. Army Corps of Engineers, Portland District, recently identified its dredging projects for 2007.
One major project is the Columbia River Consolidated Material Removal project, which was advertised as a Request for Proposal, Best Value, with a response date is April 5. Work is expected to begin in May or June.
A second major project is the Columbia River Channel Improvement Project, Phase 3. The contract was expected to be advertised in mid-April with a Notice to Proceed to be issued in June. This project involves the dredging of 3 million cubic yards to 4 million cubic yards of material by clamshell, hopper, pipeline, or any combination. The project has six upland disposal sites.
The Columbia River Channel Improvement Project is a collaborative effort between the USACE, Portland District, and six river ports in Oregon and Washington to improve navigation in the Columbia River by deepening the navigation channel. The deepening is needed to accommodate the current fleet of international bulk cargo and container ships. The overall project also aims to improve the condition of the Columbia River estuary through the completion of various environmental restoration projects.
In October 2006, civil engineering firm Thomas/Wright Inc. was awarded a contract by the USACE Portland District to provide dredging and construction inspectors for the projects.
