New Delhi: Delhi Development Authority (DDA) is going to build 42,000 flats in the time span of two years using prefabricated technique. With this technique, 22,440 flats for Lower Income Group (LIG) and 19,560 for Economically Weaker Sections (EWS) would be constructed.

The construction work for EWS flats in Rohini and Dwarka has begun, whereas it is yet to take off for LIG flats. According to the DDA, a deadline of 24 months has been set for the completion of the construction work.

In July 2009, DDA had sent a proposal to the Ministry of Urban Development for using prefabricated technique to build 50,000 flats. The authority could start construction work in recent months only after the Ministry’s approval came following the long official procedure.

At present, the prefabricated technique is being used by B G Shirke Group of Pune, which has expertise in using this technique.

With this technique, pillars for buildings would be moulded first on foundations where pre-casting of walls, roofs would be done at casting yards made at another places. All the separate units would be fixed at last using iron bolts and other things.
