The design of precast hollow core slabs is governed by the ACI (318) Building Code Requirements for Reinforced Concrete. Slab thickness is determined
by span and load conditions. Precast slabs are produced to the desired length for each individual project. Usually 8" thick slabs, capable of spanning 28'-0", or 10" thick slabs capable of
spanning 33'-0" are required for low-rise multi-family construction.
Openings in the hollow core floor system for plumbing, HVAC and stairways can easily be accomodated. These openings can be creaLed by a variety of
methods: core drilling, field sawing and manufactured block outs. All openings should be coordinated with your hollow core supplier.
