Sand Canyon Dam Liner Repair

The Sand Canyon Dam Liner Repair project entails the removal and replacement of the asphalt concrete liner on the upstream face of the dam, involving clearing and grubbing, surface preparation, removal of damaged AC sections, installation of rubberized crack-fill, compaction of subgrade materials, and placement of new asphalt concrete liner. The work is critical to maintaining the structural integrity and water retention capabilities of the dam, with all activities focused on ensuring proper adhesion, durability, and long-term performance of the repaired liner. Bidders must attend a mandatory pre-bid meeting at a designated location approximately 300 feet southeast of the intersection of Strawberry Farms Road and Sand Canyon Dam Service Road, directly below the dam face. A bid bond of 10 percent is required for all proposals, and responses must be submitted by August 12, 2026, at 9:00 PM Pacific Time. The solicitation number is 12524, posted on July 14, 2026, under the jurisdiction of the Engineering Department of Irvine Ranch Water District in California. All project-related inquiries should be directed to Andres Bernal, the primary point of contact, via phone at 949-453-5431 or email at bernala@irwd.com. The project is managed under a state and local government entity with no specific set-aside classification indicated, and all work performance is confined to the dam site in California.
