This method is having some advantages like Quick building assembly, a Lighter in self-weight, more economical enhances fire protection, Eliminating the need for temporary shoring and suspended slab forming and is linked with low-seismic zones.

These concrete precast slabs have continued tubular holes that usually have a diameter of ¾ thickness of slab which makes it much lighter than solid concrete slabs that also make the cheaper transportation costs and also these voids can be used to run the conduits and HVAC ducts.
