$28M Awarded for Bridge Painting
A $28,638,941 contract has been awarded to Certified Coatings Co. of Fairfield, CA, for cleaning and painting operations on the Richmond-San Rafael Bridge, the California Department of Transportation announced.
Certified Coatings' bid beat out four additional wagers, ranging from $31,464,000 to $46,687,580. The contract was estimated at nearly $50 million.
The 5.5-mile-long bridge carries Interstate 580 over the San Francisco Bay, connecting Contra Costa and Marin counties.
The bid due date was postponed from Dec. 17 to March 19, and a mandatory pre-bid meeting was held Nov. 20.
Scope of Work
The project involves cleaning and recoating 280,000 square feet of structural steel. The contractor will spot-abrasive blast-clean structural steel surfaces to Bare Metal (SSPC-SP 5) or Commercial (SP 6) finish. Following blast cleaning, surfaces must have a dense, uniform, angular anchor pattern of 1.5 mils.
The steel will be coated with a moisture-cured polyurethane coating system consisting of two undercoats and a finish coat. Repair, removal and replacement of coating exhibiting bubbling will be mandatory.
The existing coatings contain lead, and a containment system must be provided with a minimum vertical clearance of 15 feet and a horizontal clearance of 32 feet for traffic.
Contractors are required to obtain either a Class A or a Class C (C-33) license for this project. SSPC-QP 1 and SSPC-QP 2 certifications are also required.
About the Structure
Also called the John F. McCarthy Memorial Bridge, the structure is known for the aluminum falsework that was used in its construction. The falsework appeared like actual steel trusses, but was actually composed of built-up beams. The bridge, originally built in 1956, underwent a seismic retrofit in 2001, but retained some of its original rivets and materials, according to Historic Bridges.
