Precast concrete technology adds value and reduce cost of the project as compared to cast in-situ built.
In India, there is a huge demand for housing which neither the cities nor the housing sector is prepared for. The construction industry is also facing problems such as shortage of skilled labour, poor workmanship, low productivity and quality of construction plus time and cost overruns, to name a few. Using precast (pre-engineered pre-cast) concrete method improves the speed of construction and saves huge cost.
Concept of precast construction includes those buildings, where the majority of structural components are standardised and produced in bulk quantity which, later, together with other pieces, becomes part of a larger structure. These precast concrete elements are prepared, cast and hardened at specially-equipped plants with a permanent location in plants at project site or in a location away from the building site, and then transported to the site for assembly.
In order to get the best result from the precast concrete technology, experienced precast architects or structural engineers are required, along with well-trained and experienced erection crews are also must to carry out the site work with utmost satisfaction. Precast concrete products do not need any finishing (such as plastering) on site. By using coloured aggregates and form liners beautiful patterns can be achieved on facades/outer load bearing walls of building.
The precast concrete building technology can be efficiently and effectively used for townships, affordable and low-cost mass housing, IT/ITES parks and SEZs at a much competitive cost and on-time schedule to be adopted in the construction sector of India.
