Lift slab rises on tight site
Techniques of lift slab construction used in building 14 story Mall Motor Hotel in Dayton, Ohio are described; slabs were lifted maximum of 145 ft from basement to roof, 134 ft above street level; structural steel wide-flange columns spaced 25×20 ft c to c support slabs, which measure 198×68 ft for first three floors and 151×61 ft for others; as columns were erected to full 14-story height, temporarily parked slabs rode up in stages; heaviest slab, at first floor level, weighs 585 tons, upper floor slabs weigh 425 tons each; post-tensioning of slabs began when concrete had attained minimum compressive strength of 3600 psi.
