Liberty Maintenance Inc. has been awarded a contract by Washington Station Department of Transportation for the cleaning and coating of the Aurora Bridge, located in King County.
|
Liberty Maintenance Inc., of Youngstown, Ohio, was the second-lowest of four bids. Additional bidders included:
-
Alpha Painting and Construction, of Baltimore, in the amount of $28,754,321.26;
-
F.D. Thomas Inc., of Central Point, Oregon, in the amount of $33,751,910.74; and
-
Certified Coatings Company, of Fairfield, California, in the amount of $35,500,810.78.
Scope of Work
The awarded contractor will oversee the cleaning and recoating of the 2,945-foot-long by 70-foot-wide cantilever and steel-truss bridge. The Aurora Bridge, also known as the George Washington Memorial Bridge, was first opened to traffic Feb. 22, 1932, and is listed on the National Register of Historic Places.
The bridge was last coated in 1984 with a lead-based paint. Steel surfaces will require brush-off blast cleaning (SSPC-SP 7). Surfaces inaccessible for blasting will be prepared according to commercial-grade power-tool cleaning (SSPC-SP 15). Following brush-off blast-cleaning, the awarded contractor will perform commercial spot abrasive blast-cleaning (SSPC-SP 6). Containment is required during blast-cleaning. While cleaning the steel surfaces, additional repairs will be made to an expansion joint on the bridge deck, and six other expansion joints will be resealed.

Because the bridge’s floor beams and stringers were already cleaned and recoated in 2016, as part of Stage 1 of this project, only the trusses and remaining exposed steel surfaces are left to coat. These surfaces will receive applications of a moisture-cured polyurethane system. Owner-approved manufacturers are Wasser and Sherwin-Williams.
The awarded contractor will also oversee the application of 18,717 square yards of a waterproof membrane. A special provision for non-slip surface treatment is included. Owner-approved manufacturers are Daubert Chemical and PPG/Ameron.
The project is scheduled to begin in early 2018 and be completed by fall 2019.
