Pre-Cast Technology: An Initial Step to Sustainable Development

Erection of precast construction unit is a complex mechanized process for continuous assembly of buildings and installation of prefabricated elements and components. Precast construction provides advantages over conventional practice by costing the pre definite size of the members (penal, walls, beams, columns) in the factory. In this technique the structural members specially made of concrete that has been cast into form prior being transported to its construction location for the final installation work. Precast construction technique is the first step to satisfy the demand of sustainable housing for the population in developing country. It is also one of faster construction process which also provides high quality. This Paper cover different types of precast construction system, its main features, equipment required for the construction work and its installation process for different type of components.
