Abstract: Prefabricated, steel framed, rectangular building modules are joined in groups to form multi-unit residences, or commercial or institutional buildings. The modules are disposed in rectangular groups abutting one another so as to form a central rectangular core bounded by the units. Utilities are connected to each module through the core. Multiple story buildings are formed by similar groups having cores aligned vertically. Alternating stories are rotated relative to one another about the central core axis to produce cantilevered structures.

Abstract: A building module for housing purposes comprises a rigid, rectangular, three-dimensional truss formed with four steel end columns and steel beams extending between the columns. Each module includes a floor panel extending between the four end columns, wall panels, and a roof panel extending from two of the end columns, parallel to the forward column and terminating a spaced distance from the two end columns. A first rectangular folding panel has one end hingedly attached to the edge of the roof panel termination and a second rectangular folding panel, larger than the first rectangular folding panel, has one end hingedly supported between the two end columns. The first and second rectangular folding panels may be folded into positions parallel to their roof panel with their edges overlapping to form a compact module.

Abstract: Modular operating centers for use in electric power generating plants and other industrial and commercial plants, processes and systems are constructed by using a novel prefabricated modular technique. This technique includes loading a plurality of transportable room-size building modules with control system equipment at a factory site. Typically, the control system equipment includes sophisticated and complex electrical and electronics data processing and control equipment. The control system equipment is installed and bolted down in the different building modules and the equipment in each module is inter-wired at the factory site. Temporary inter-module connections are established between the control system equipment in different ones of the building modules and such equipment, as a whole, is then thoroughly tested and adjusted under simulated use conditions. Thereafter, the loaded and tested building modules are separated and separately transported to the industrial or commercial installation site.
