Using Precast beams and columns will save considerably on cost and time as time-consuming shuttering and scaffolding are avoided.
 

As production takes place under controlled conditions, the productions are of higher quality and more accurate compared to in-situ work.
 

Precast columns and beams are fast to install, and does not require any storage space on site, as the units are generally erected directly from the trailer into its final position.
 

Using prestressed beams will enable large spans, which open up waste areas inside the building.
 

Shorter building period, lesser reliance on site labour and no   requirement for scaffolding contribute to cost saving.
