Objective:
Design and install a complete OSHA and ANSI/IWCA I-14.1 compliant suspended maintenance system. Wrap around beam roof anchors were installed on top of concrete and wrapped around beams below. These anchors did not require any under-deck bracing. Cast in place wall anchors were economical and were installed where possible. In other areas where access to tie offs was required, weld to beam roof anchors were installed. Weld to beam roof anchors were installed where concrete did not exist and were either installed on beam intersections or the midpoint of a beam. Where anchors were installed on the midpoint of a beam, under-deck bracing was required.
