Describes the salient design and construction features of a two-story precast and prestressed concrete building at the Developmental Center of the Boeing Airplane Co., Seattle, Wash. The floor area was more than 500,000 sq ft, which was cast, erected, and completed in about 14 months. The story heights are 25 ft each. The column spacing is 60 x 40 ft on the second story and 30 x 40 ft on the first floor, so that the column lengths are alternately 50 and 25 ft. Details and construction procedures were used which developed full continuity at all joints of the precast members and also achieved load-carrying participation of the roof deck and second floor slab. The majority of the precast and prestressed members were fabricated on the site, including end-supported pre-stressed lightweight concrete wall panels as high as 20 ft and spanning a maximum of 40 ft.
