Survey of Precast Concrete Method and Cast-in-Situ ...

2017-8-24  Time saving- Precast concrete method requires less time for onsite construction as compared to Cast-in-situ concrete method, because as prepared materials are transported to site and can be directly lifted and placed on the desired position. Precast elements can be delivered just in time for fast erection, reducing unnecessary handling and equipment use. With minimal propping and bracing, and with precast flooring providing an immediate working platform, precast concrete allows other trades to begin work more quickly, speeding the construction time and saving costs. Fast construction on site also means fewer disturbances for surrounding properties. Cast-in-situ method
