Construction system and method for constructing buildings using premanufactured structures

1. A method of constructing a multi-level multiple unit building comprising:

premanufacturing non-weight bearing walls at a site distant from a building site;

positioning an exterior visible primary load-bearing steel assembly at the building site that provides lateral outermost planar surfaces of the building that are offset and external to any outermost planar surfaces provided by premanufactured non-weight bearing walls after the building is constructed;

pouring at least a first monolithic concrete slab, a second monolithic concrete slab, and a third monolithic concrete slab at the building site;

lifting the third monolithic concrete slab, wherein a top surface of the third monolithic concrete slab comprises a roof of the building and a bottom surface of the third monolithic concrete slab comprises a ceiling of a building level below the third monolithic concrete slab;

employing a top surface of the second monolithic concrete slab as a shared floor of an upper building level comprising multiple units;

employing a bottom surface of the second monolithic concrete slab as a shared ceiling of a lower building level comprising multiple units; and

attaching the non-weight bearing walls to the bottom surface of the third monolithic concrete slab and the top surface of the second monolithic concrete slab.
