What happens when an elevator gets shut down on a 9-story building renovation? Put up a temporary elevator on the outside…Buck Hoist. But before the buck hoist can be installed, it must be anchored. Before it gets anchored, the concrete needs to be scanned to keep the structure and the buck hoist secure.
GPRS was called on to scan for the buck hoist anchors during a renovation of a dorm building at UNC Charlotte. The areas for the anchors were successfully scanned, and the anchors for the buck hoist were installed without touching any rebar.
To complete this job safely, the general contractor drilled holes in the corner of each room, so that any worker in the room could use a temporary concrete wedge anchor connected to a self-retracting lifeline (yo-yo). This made transitioning from room to room quick, efficient, and safe.
The equipment used to scan was the 2GHz Palm GPR antenna. This antenna provides high-resolution images at depths up to 12-15 inches, depending on concrete conditions. The smaller profile allows scanning in tighter spaces than normal GPR concrete antennas. The 4000 SIR unit was used to receive the radar signal and display the signal on its screen. This equipment along with the experience of GPRS project managers lead to accurate and helpful findings.
Upon completion of the job, a job summary report is sent giving information on the work that was done: site specific information, findings, equipment used, and advice for safely proceeding with the job.
