Construction on the HMA plant began in January and was completed in May. It has additional seismic safety bracing due to the numerous earthquake faults in the Bay Area, with a 4.5-foot thick silo foundation that took more than 800 cubic yards of concrete to construct. The silo legs feature 2-inch bolts embedded in 3.5-inch concrete, and the silo legs took four certified welders five weeks to weld to the pads. The plant also boasts state-of-the-art emissions controls. The plant is located at 6527 Calaveras Road in Sunol. The order desk is (925) 829-1446 and the Quarry Office is (925) 862-1909. CA
