Special structural design

Approved by Building Material and Technology Promotion Council (BMTPC- under Ministry of Housing and Urban poverty Alleviation, Govt of India).

Special structural design

These panels are cut into required sizes using a computerized machine at at the factory and brought to the construction site to used for all parts of the building, right from walls to staircases to roofs. Trenches are first dug at the construction site and the bottom surface is plastered with cement. The foundation is made of conventional fly ash bricks and plinth beams are cast on it. The entire gap is filled with soil and then plastered with cement. This process takes 11 days to complete.

The Building Materials and Technology Promotion Council of India has approved the design. All hollow parts at the joints are filled with concrete and vertical walls are reinforced. These serve the purpose of conventional reinforced concrete columns.

Then walls, staircases and finally the roof are built using gypsum panels. The hollow gaps between two panels of the roof are filled using the concrete mixture and they are also reinforced. Special structural design is prepared for the building to withstand lateral loads such as earthquakes and storms. PhD students from IIT Madras struggled hard to design the structure for seismic loads.

Gaps are provided for plumbing and electric works. The conduits are made before concrete is placed on the roof. Care is also taken to drain rainwater by providing a slope. A multi-storey house can also be built by using gypsum panels as walls in the similar manner done at the ground floor. The joints are filled with concrete.
