RFID Reduces Wait Times on TransBay Transit Center Construction Project

Pre Conference Session
Accurately monitoring the curing of concrete can be critical on large construction projects. Shimmick Construction Co. has deployed an RFID solution consisting of active ultrahigh-frequency (UHF) RFID tags with built-in sensors, as well as handheld readers and software to interpret the collected temperature data for the construction of San Francisco's new TransBay Transit Center. The tags' sensor probes are embedded in each concrete slab and the data is read remotely, making the system more nimble than conventional data loggers. The system has been able to determine that concrete has adequately cured within about two weeks after it is poured—approximately half the time the company would have had to wait without the sensor data, and has paid for itself three to four times over, based on the reduced wait times.
