To ensure structural stability and achieve the unconventional awe-inspiring aesthetics

Specific solution/technical details

22 sculpted steel 3 D trusses each having different span resting on 2 elliptical beams and one grand central Arc . Peripheral elliptical edge beams are resting on V columns. Intricacy of Sculpted expressions of engineered end connections of trusses and V columns is achieved by machined steel casting process. The entire building envelop has 6500 tons of steel manufactured inland at various cities and carried to Port Blair assembled by 400 ton cranes. Commissioning and decommissioning of cranes at Remote Island was a project by itself.

Impact or effectiveness

20 clear strip skylights located right above space trusses gives pleasant daylight thus not only saving day time lighting energy, but gives uniform lux lighting across the interior space and hi lights meticulously detailed space truss detailing and geometry.
Roof has delicate mesh overhang extensions receding façade. This prevents any direct sunlight exposure on glass facade during harsh sunlight durations to minimise heat gain through glass façade. Choice of Glasses are having better shading coefficient to further reduce heat gain.
