By using precast-concrete hollowcore slabs, the building team for Renaissance Plaza-an 11-story apartment and retail complex in New York City's Morningside Heights neighborhood-was able to shave erection time and cut project costs. The 360,000-sq.-ft. project, which is part of a $125 million area revitalization, was designed by Greenberg Farrow Architects, New York City, and contracted to Levine Builders of Douglaston, N.Y.
The flooring system allowed for the use of long spans, which reduced material costs for the facades and eliminated additional fireproofing material. Also, the 8-in.-thick slabs serve as both floor and ceiling elements, as compared with the 17 inches of space needed for a typical metal deck and dropped ceiling.
