New Delhi: Racing against time to complete
its projects, Delhi Metro will build one station on the
Central Secretariat-Gurgaon line fully in steel as it takes
less time compared to the conventional construction in
concrete.
The Chhattarpur station of the Central Secretariat
(CTST)-HUDA City Centre (Gurgaon) line will be fully built in
steel and this will be the only station on the entire Delhi
Metro Rail System which will be made fully of steel.
"The DMRC had to resort to this rather unconventional
construction technique at Chhattarpur to ensure that the
Central Secretariat (CTST)-Gurgaon corridor was opened to the
public on time before the Common Wealth Games starting later
this year," a DMRC spokesman said.
The usual technique of making stations in concrete
would have taken at least two years for construction which
would have delayed the Metro line substantially.
By adopting this method, the DMRC will be able to open
Chhattarpur for thorough running of trains on the Central
Secretariat-Gurgaon line by June this year. Trial runs on
one part of the line have already started.
DMRC was trying to acquire land in Chattarpur area
since September 2006, but it was able to get about two
hectares only in October 2009 after prolonged litigation.
The station, which will be built using special
structural steel, will be completed in about eight months.
About 70 per cent of the work has already been
completed and four cranes of 20 ton capacity each are engaged
at the site for lifting, holding and bolting works.
The quality of the structures is being checked through
Radiography of the joints (X-ray) and DPT (Dye-Penetration
Tests, the spokesman said.
After the erection of the steel structures, 180 mm of
concrete will be laid on top. The procedure, however, is more
expensive and will cost DMRC an additional 30 to 50 per cent.
The rest of the building will take more time for
construction and the station will be opened by August 2010
when the entries/exit/finishing will be done.
At Chhattarpur, the DMRC is also setting up a
Receiving Sub-Station (RSS) on a hectare of land. The RSS will
also be ready at a later date and therefore, temporary
stand-by arrangements have been made close-by.
