Structural design of the Research & development lab for Torrent Pharmaceuticals. The lab is spread across a built-up area of approx. 16,000 m2 with 3 interconnected ground floor blocks and 3 upper floors. The structure is designed to provide large column free spaces, enable coordination and pre-determine routes for a number of utilities. Large cantilever beams support the load of 3 floors above. To replace cement, 33 % fly ash was used in the structural concrete.
