1 PRE-CAST HOUSE CONSTRUCTION

2 BDA is a Planning and Development Authority Jurisdictional Area is 1370 sq.km. Developed 64 Layouts Distributed 1,40,000 of sites Developed Infrastructure Works like Ring Roads & Grade Separators. BDA is also responsible for approval of Development Plans and Layout Plans of private agencies

3 BDA has now taken up Construction of Affordable Housing Projects. Over Housing Units are under Constructions units have been completed. To encourage latest available fast track methods of construction, flexible tender conditions adopted.

4 FOUR DIFFERENT CONSTRUCTION TECHNIQUES ARE BEING USED AT PRESENT

5 1) CONVENTIONAL METHOD 2) A MANOLITHIC CAST-IN-SITU SHEAR WALL CONSTRUCTION 3) PRE CASTING OF ELEMENTS OF FRAMED STRUCTURE 4) PRECAST PRE-ENGINEERED METHOD OF CONSTRUCTION

6 TWO TYPES OF PRE CASTING CONSTRUCTION

7 PRE CASTING OF ELEMENTS OF FRAMED STRUCTURE - Elements of framed structure including slabs are precast and will be assembled at site

8 PRECAST PRE-ENGINEERED METHOD OF CONSTRUCTION - Load bearing wall elements are precast which will be assembled in to cubicles at the factory. All finishing's will be done at factory. The finished cubicles will then be transported and erected at site

100 ADVANTAGES OF PRE CAST CONSTRUCTION TECHNIQUES Optimum use of Construction Materials : Fly Ash and GGBS are used to maximum possible extent. Very Less Wastage of Construction Materials. Better Quality Control : As the components are manufactured in control factory environment : Rigid and uniform quality control is possible. Recycling of Material is ensured : Usage of River sand and Water reduced substantially. Clean and Healthy built / construction environment. Environmental Friendly, Energy Efficient, Green Building Construction is possible. Construction time is reduced substantially.
