Comment | More

Estimated at almost $50 million, the California Department of Transportation is seeking bids for the painting of the Richmond-San Rafael Bridge.

The 5.5-mile-long bridge carries Interstate 580 over the San Francisco Bay, connecting Contra Costa and Marin counties.

Bids are due Dec. 17, and a mandatory pre-bid meeting will be 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.

Caltrans / William Hall

Caltrans is seeking bids to clean and recoat the 5.5-mile-long Richmond-San Rafael Bridge over the San Francisco Bay. The project is estimated at close to $50 million.

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.

Reported by Paint BidTracker, a construction reporting service devoted to identifying contracting opportunities for the coatings community.

Comment from Raymond Merrill, (11/13/2013, 8:59 PM)

Two comments: 1. Why not just say "SSPC-SP 6, Commercial Blast Cleaning" rather than "spot-abrasive blast-clean...to Bare Metal (SSPC-SP 6"? 2. Did I read that correctly that "surfaces must have...an angular anchor pattern of 1.5 millimeters"? I hope someone really carefully reads the specification before bidding on it!


Comment from Kristen Reiner, (11/14/2013, 11:43 AM)

Raymond, our apologies. The specification reads “Blast clean all steel surfaces on bridge no. 28-0100 to bare metal under SSPC-SP 6/NACE No. 3.” The article has been corrected to reflect the specifications. Also, we erroneously printed “millimeters” and the correct measurement per the specifications should be mils. Thank you for bringing this to our attention.
