RMA served as the prime contractor for the construction of a flood wall as part of Phase 3C of the Guadalupe Flood Control Project. The flood wall we constructed diverted the channel’s out-of-bank northward-flowing floodwaters back to the main channel of the Guadalupe River through downtown San Jose.

The project consisted of concrete masonry, installation of sheet pile floodwalls and removable water barriers, including installation across active Santa Clara Valley Transportation Authority (VTA) rail tracks. After procuring all materials and equipment, RMA performed extensive site management to coordinate a 25-man crew and multiple subcontractors to ensure that VTA lines would be fully operational within a 52-hour window. Working in shifts overnight, RMA finished the concrete pour eight hours ahead of schedule. We used specially designed concrete mixes that achieved the required the 1000 PSI strength within four hours.

Work features included construction of temporary access roads; construction of sheet piles; excavation, trenching, and backfill; hardscape and landscape renovations; installation of irrigation and water lines; installation of communication lines; design-build concrete mix; and extensive concrete and masonry.

RMA earned two letters of commendation and an Outstanding Performance Evaluation from USACE, Sacramento District, for effective project oversight, quality control, schedule management and responsiveness. RMA also received a nomination for Sacramento Contractor of the Year.
