KANSAGRA VADI SCHOOL PLAN

Post the 2000 earthquake, huge quantities of rubble from broken buildings was thrown outside the city. This along with industrial wastes like fly ash (from a GEB thermal plant), gypsum (waste from the sanitary ware industry at Than) and lime (waste from Tata Chemicals Ltd., Mithapur) was used as the primary building block.

The trusses for the roof aremade from steel pipes broughtfrom the ship breaking worksp gat Alang and the roofing itselfincorporates the renewablematting of date palm leaveson the bamboo frameworkover which is laid thatch asfinal layer.

Out of the total cost of construction, building materials contribute to about 70 percent costs in developing countries like India. Therefore, the need of the hour is replacement of costly and scarce conventional building materials by innovative, cost effective and environment friendly alternate building materials. The new material should be environment friendly and preferably utilize industrial/agro wastes because as a result of rapid industrialization, the generation of wastes has increased several fold during the last few years, which needs to be utilized/disposed safely on priority.

Hollow blocks used in the large span slab reducing the dead load of the slab and in turn the percentage of steel used in the structure

The Building saves concrete and steel required for peripheral columns by using load bearing walls all along the periphery of thee u d g sa es co c ete a d stee equ ed o pe p e a co u s by us g oad bea g a s a a o g t e pe p e y o t estructure.The structure uses flat hollow block slab which effectively reduces the amount of concrete used.The use of hollow blocks in the slab reduces its dead weight and in turn saves on the steel used in the slab. The slab Minimizes the stirrups used to tie the horizontal reinforcement, further saving time and energy.

The point that one wishes to drive home through this presentation is that

architecture that Recycles, Reuses and Reconfigures begins to provide an

important platform for innovation in the production of new possibilities in

the construction industry.

The challenge is how do we mainstream these possibilities !!
