Cast-in-place concrete connects precast members
Prestressed structural T's with tops 8 ft wide, were spaced at 15 ft on centers to roof commercial building; bolts through T's and temporary shares supported beams during erection; precast slabs 2 in. thick and 8 ft long -- with prestressing wires protruding 12 in. at each end -- were laid across 7-ft opening; then cast-in-place concrete was placed over T's to bond roof slabs and T's into rigid unit; saving of 1 dollar/sq ft is claimed for this type of construction.
