This structural detail outlines design loads and geometric constraints for davit pedestals and fall arrest tiebacks. The davit pedestal requires a six-inch minimum diameter and a seven-foot maximum height, supporting a dead load of two hundred pounds alongside maximum operating loads multiplied by a four-factor safety margin. Loads are assumed to rotate three hundred sixty degrees in a horizontal plane about the pedestal center line. The fall arrest tieback requires a four-inch minimum diameter and a two-foot six-inch maximum height, resisting a five-thousand-pound ultimate load in any direction at its top center. Both steel assemblies are tied to elevations specified on plan.
