Describe the process of lift-slab construction.
What will be an ideal response?
Lift-slab construction involves casting a reinforced concrete slab for each floor of a building and the roof, one on top of the other. The ground floor on-grade slab is cast first. It is coated with a bond release compound that prevents the next slab from bonding to it. Slabs are cast for each floor and for the roof, if it is to be a concrete slab. Each is coated with a bond-release compound. The slabs, usually two-way flat slabs, can be reinforced concrete flat slabs or pre-stressed. The slabs are lifted by hydraulic jacks mounted on the tops of the columns. They slide up to the desired elevation and are secured to each column by welding, bolting, or a series of pins. This is repeated for each floor.
