Which method of construction allows slabs to be poured in situ and lifted later?

The Lift Slab Method is designed specifically so that slabs can be poured on the ground or at a lower level and then elevated into place after the concrete has set. This technique involves pouring concrete slabs at the ground level and then using hydraulic jacks or cranes to lift those slabs vertically to their final position.

One of the primary advantages of this method is that it allows for significant efficiency in construction. Since the slabs are cast in place and then lifted, it reduces the need for complex framing and forms typically required in traditional construction methods. Additionally, the lifted slabs can be positioned accurately without extensive scaffolding, which can save time and resources during the building process.

This method stands out from the other options because it specifically incorporates the concept of pouring slabs in one location and moving them to another, which is not the primary focus of traditional slab systems, precast concrete methods, or tunnel form construction. Each of those methods involves different processes regarding the casting and placing of concrete, but they do not utilize the lifting technique inherent to the lift slab method.
