Abstract:
Describes construction of a five-story hospital with solarium. Lift slabs are 43 ft x 182 ft x 8% in. for the first five floors, and 41 ft x 80 ft x 8 1/2 in. for the solarium roof which was lifted 62 ft. Special shear blocks made it possible to hold the slab in its lifted position with 1% in. pins during welding. This freed lifting equipment to proceed with the next slab. Columns were 14-m. wide flange sections erected in two parts. Top slabs were lifted to the top of the first section and held temporarily while bottom floors were set in final position. While bottom floors were being welded, the top section of the columns was erected and the top slabs placed in final position.
