“In the old days, we would hire a security guard at the door of every clean room so no one would go in,” says Osman Chao, project executive at DPR Construction, who recently adopted Trimble’s ThingMagic, a radio-frequency identification (RFID) system that has replaced the guards at egress points and helped automate his site security.
Before the job began, Chao was faced with securing a 900,000-sq-ft site with many work zones and four phases of building protocol in which the level of cleanliness would increase with each phase. “Cleanliness isn’t a big issue when we’re building up the structure, but the minute the building is closed in and we’re building out the interiors, we need to make sure we regulate what gets into certain areas,” says Chao.
