The bright lights on the circular periphery of Jawaharlal Nehru Stadium are now visible from a distance as October 3,the big day when the Commonwealth Games kick off at the stadium,inches closer.
The stadium,which will hold both opening and the closing ceremonies,is the main venue for athletics and will also host lawn bowl and weightlifting competitions.
OPENING & CLOSING CEREMONIES
For the opening ceremony,the Central Public Works Department (CPWD) has added a last-minute change to the original plan. An underground tunnel has been built through which performers can emerge directly at the centre of the stadium.
The design for the tunnel came in November 2009 and is expected to be completed by this May.
The tunnel will have three openings,one at each sides and one at the centre.
The stadium was built in 1982 during the Asian Games. For the Commonwealth Games,our biggest challenge was to renovate the stadium without affecting the ground. The construction was done carefully, CPWD director-general B K Chugh says.
The stadium earlier did not have a roof. The government hired German structural consultancy engineers Schlaich Bergermann und Partner. The firm had designed for the European Parliament in Luxembourg and the ever-delayed Signature Bridge at Wazirabad in the Capital.
Being built at a cost of Rs 308 crore,this is the first time a Poly Tetra Fluoro Ethylene (PTFE)-coated glass fibre membrane is being used for the roof. In laymans language,PTFE is the material used to make non-stick pans.
With an area of 53,800 square metres,it is the worlds biggest roof being constructed with PTFE,and the first time being tried in India.
The primary roof structure has a larger diameter that results in an inclined outer structure. This primary structure is then balanced by x-shaped steel cables which also connect it to a third ring.
The third ring is the membrane roof made of PTFE-coated glass fibre. This membrane has been manufactured in Mexico,and 71 lifting jacks were put in to raise the cables.
Like the Asian Games brought colour TV to India,the Commonwealth Games will unveil high-definition TV. The mastheads and the overall lighting of the stadium have been done to enable high-definition television transmission. Swiss firm GE Sports is handling the work.
