Construction Catalysers Targeting Technology

Archery Stadium

Apart from the heartening fact that Commonwealth Games 2010 is about to host an archery competition for just the second time in the history of the Games, archers have yet another reason to rejoice. A state-of-the-art archery stadium has been designed by Pune-based Construction Catalysers Pvt. Ltd. at Delhi Development Authority's Yamuna Sports Complex in East Delhi that is expected to captivate the imagination of technology-gazers and sportspersons alike. The stadium is the first large-scale development flagged off by the DDA for gearing up the sports infrastructure of the city with respect to the Commonwealth Games 2010 (3-14 October 2010).

Overview

The stadium will host Archery Preliminaries apart from numerous other sport events in the near future. A basic curvilinear form ensures unhindered play-view from all sides. The world-class design is spread over a site of 4.8 hectares and houses spectator seating, air-conditioned lounges, changing rooms, medical and physiotherapy, doping control, logistics, cafeteria, venue management store facilities. The 4274 sqm of plaza level is specially designed respecting the differently able. Special lifts, toilets and ramps ensure easy accessibility throughout the stadium and convenience of use. An external concourse area sweeps around the perimeter on the first floor, apart from housing the lounges and spectator's seating. The second floor contains the Commonwealth Games' family lounge and the media centre and the grand stand sports a seating capacity of 1500 spectators.

The Roof

The USP of the project is the unique roofing that covers the stadium. 22m deep cantilevered tensile structure sweeps over the stadium providing shade to the seating area. A main Reinforced Cement Concrete (RCC) structure supports the arched steel trusses that act as the main supporting members. These trusses are cantilevered on both sides and are arranged along the seating area spaced at 7 m c/c. Finally, white translucent fabric is fixed both on top and bottom of the arched girders transforming the structural framework into a seamless roof. The translucent fabric allows diffused daylight in, without revealing the structural members and in this manner, with minimum distraction to the eye, spectators can enjoy the game in an utmost aesthetic ambience.


For a clean look and clear vision the rain water gutters are concealed within the fabric roof. The collected water is guided further to the main rain water recharge area of the complex.

Nashik Engineering College Library

A library building with glass façade looking East – For the Rising Sun…
The spacial architectural space represents openness, an unending curiosity, a place for open, free and unhindered interaction and debate. Further the library of an Engineering College should represent the spirit of engineering, display immaculate structural design and motivate engineering students to create unprecedented feats of Engineering and excel.

The Structure

The 65M. X 35M Wave Roof is resolved by a unique combination of 4-trusses and 6-wave girders supported with G.I. V-columns. Each girder is a composite box section made out of steel plates with tensile cables and varying depths as per the wind load and stresses. The unique combination of steel components: such as Wave Girders, Optimized trusses, V-columns resonating the rhythm and metal sheet cladding has resulted in a mass-less effect.
