It all has to happen in proper sequence and coordination,” says Tarrosa. “We also did not want to open areas where there can be a huge risk to the traveling public.” Pours were broken down to 700-foot-long sec- tions and 5,000 and 6,000 psi high early mixes were used in order to open up the intersections and lanes as quickly as possible. Along with concrete used for the 12-in. tall curb and 13-in. deep concrete pavement protruding 12 ft. from curbside to serve as the bus lane, Griffith Company also poured concrete bands and sub slabs for the intersection crosswalks—usingmore than 350,000 square feet of concrete. The secret to success for this project, which won a transportation project award from the Los Angeles Section of the American Society of Civil Engineers was really the people, says Tarrosa. “We knew that this would be a high profile project so we assembled a team of veteran employees who worked well together and were experts in their roles,” he says. “They knew how to build the pavement so that water drained properly, and the ride was smooth due to good transitions from new to old pavement.” Af ter Construction
