The Central Public Works Department, the main construction arm of the government, on Monday said that upgrading of all venues for the Commonwealth Games will be completed in a fortnight.
"We have already completed 7 of the 10 Games venues. The remaining three will be completed in a fortnight," Director General of CPWD B K Chugh said on the 156th foundation day of the organization.
The venues which remain uncompleted so far are the Jawaharlal Nehru Stadium, the SPM Swimming Pool complex and the new weightlifting stadium in the Nehru Stadium complex.
Chugh said that the civil work in all these venues have been completed and only the peripheral work like greenery, pavements, laying of cables was being done which is expected to be over in another 15 days.
The CPWD DG said the JLN Stadium, where the opening and closing ceremony along with the major events would be held, has an innovative design for roof over seating tier. State-of- the-art technology has been used for sports lighting.
"This would be the largest membrane roof structure in the world," Chugh said. Membrane roofing is used to prevent leaks and move water off the roof.
Asked about the delay in construction of the main stadium, he said an additional work of tunnel construction was given which delayed the project for a while.
An air-conditioned tunnel for the performers of the opening and closing ceremonies has been completed inside the stadium below the athletes' track and arena.
"This requirement came quite late and to accommodate this tunnel, all the remaining works related to roof, track etc had to be rescheduled," he said.
"Cable supported halogen balloons would also be placed inside the stadium which required a base, thus delaying the project," he added.
Chugh described the Nehru stadium as a "modern engineering marvel". He said likewise, the SPM swimming pool has been converted into a fully air-conditioned complex and it is the example of a design innovation, architecturally and structurally.
The DG said that two new venues have been constructed inside the Indira Gandhi stadium complex. He said an indoor air-conditioned timber track cycling velodrome has been constructed in place of the existing concrete velodrome and has been accredited to be the second best in the world after the one in Beijing.
The other venue is a fully air-conditioned wrestling stadium which is adaptable to multiple uses, he added.
Giving the features of the new weightlifting stadium in the Nehru Stadium complex, Chugh said it was unique in design. From outside, it appears like an egg shell, he said.
It will also be the largest auditorium in Delhi with a dedicated double basement parking and could be used as such after the Commonwealth Games.
For all the venues of the Games for which CPWD was engaged, the government sanctioned Rs 2460 crore of which Rs 1867 crore had already been spent by June 2010.
The DG said that beautification of the city was currently going on which includes cleaning of the canals on both sides of Rajpath, whitewashing of the buildings and cleaning the road dividers and tiles at all places which the delegates and players are expected to visit.
Officials said CPWD had also commenced the construction of three high-altitude roads at 12000 to 17000 feet in Uttarakhand bordering China and will undertake construction of three more such roads in Sikkim shortly.
The organization completed fencing in 265 km of length along Indo-Bangla and Indo-Pak borders last year.
