Abstract: Disclosed are various construction techniques for erecting a multistory building with an elevator shaft. In accordance with the method, upper and lower shaft components are formed at an offsite facility. These shaft components are then joined together to form a segment of the larger elevator shaft. Once constructed, the segment is transported to a jobsite and erected. Once an individual segment is installed, a floor slab can be formed about the segment. Using pre-cast elevator segments simplifies and expedites the construction process. In one embodiment, each segment includes a serrated edge that facilitates a connection between the floor slab and the shaft segment. Rebar and reinforcing dowels can also be used to improve the connection. Associated shaft constructions are also disclosed.
