Abstract
A multi-story modular structure is constructed of a horizontal and vertical array of modular units. Each unit forms an enclosure of a space and is comprised of a perimeter frame, side walls rising from the perimeter frame and a ceiling truss connected to the side walls to complete the modular unit. The modular unit has integrated into the side wall four lifting points. Each lifting point includes the reinforcement within the truss structure and in the perimeter frame for receiving a lifting rod. Lifting rods, which form part of the lifting harness and not part of the modular unit are then placed into the modular unit and the unit can be horizontally or vertically moved by a construction crane through the use of a universal or reusable overhead harness. Lateral stiffening of the multi-story structure constructed from such modular units is accomplished by means of integral diagonal straps designed into the exterior sidewalls of the outer modular units between each of the window frames within the outer side walls. The number of stiffening straps decreases as the position of the modular side wall ascends in the multi-story structure.
