Forming and stripping practices, particularly for flat slab and flat plate construction, have developed to a high degree of efficiency during the past 25 years. Contractors, with the aid of structural engineers, have been able to reduce the slab cycle time to a bare minimum consistent with safety. A procedure for using preshores during the stripping of primary forms and shores has been developed over the past two decades by a New York firm. This procedure allows fast cycling of reduced sets of primary forms while maintaining full support of the newly placed floors during a stripping operation that may commence as early as 24 hours after placement of concrete.
