Lwsc large lock center gate replacement

The U.S. Army Corps of Engineers Engineering District Seattle seeks to replace the two existing 100-year old center miter gate leaves at the Lake Washington Ship Canal Large Lock in Seattle, Washington. The project requires the removal and disposal of the existing gates, which each weigh approximately 375,000 pounds, as well as fabrication, delivery, and installation of two new gate leaves. Interested parties must submit capability statements and supporting documentation by April 16, 2021 demonstrating their experience with similar projects, with contract award determined based on a full and open competition evaluation of technical qualifications.

There is no set-aside designation for this requirement. The primary NAICS code is 237990 and PSC code is W and the project value is estimated between $10-25 million. The replacement gates must be installed within the constraints of the 80-foot wide by 825-foot long lock chamber by January 31, 2022 to accommodate lock outages from November 15th through that date for in-water work only permitted from October through February.
