Abstract: A modular elevator system has a pit module, one or more shaft modules that are attachable to the pit module and/or to an adjacent shaft module, and a cap module that is attachable to an uppermost shaft module. The pit module, the shaft modules, and the cap module are each pre-fabricated and transported to a site at which a building is under construction for assembly top of the pit module, the remaining shaft modules are secured sequentially on top of each other, and the cap module is secured on top of the uppermost shaft module.

Abstract: A connector system for interconnecting vertically adjacent and/or laterally adjacent modular units of a building constructed from such modular units assembled rigidly together includes connectors that are rigidly attached to the modular units. These connectors are able to rigidly interlock with each other so that, when the connectors of adjacent modular units are interlocked with each other, the adjacent modular units are also rigidly attached to each other. The connectors include sliding alignment features that ensure that resist lateral displacement of laterally adjacent modular units and also ensure proper alignment of vertically-engaging retention features that resist vertical displacement of vertically adjacent modular units.

Abstract: A system (10) for covering an exterior external surface of a building includes cladding alignment features attached to the external surface of the building according to a predetermined pattern and cladding panels (100). Each cladding panel includes a structural frame (130), a substrate (110) attached to a first, external, surface of the structural frame, and fasteners (200) that are formed on a second, internal, surface of the structural frame. The fasteners are arranged according to the same predetermined pattern as the cladding alignment features, such that each of fasteners can be aligned with and attached to a corresponding one of the cladding alignment features. Each of the fasteners is attachable to a corresponding one of the plurality of cladding alignment features. The building is formed from multiple modular units assembled together. Each of the plurality of cladding panels is affixed to one or more of the modular units.
