The mood was upbeat in the Bangalore Metro Rail Corporation Ltd., premises on Wednesday with the Namma Metro achieving a major milestone in the project civil work — completion of the entire viaduct construction for Reach 1 between Byappanahalli and Cricket Stadium.

With the construction workers beginning the work on last of the 1,938th segment at Byappanahalli on Wednesday morning, this major milestone on Reach 1 was achieved. The completion comes ahead of the scheduled commercial launch of metro services on this stretch by December-end.

Chief Engineer of Reach 1 Hegga Reddy told presspersons that tireless efforts of the personnel of Bangalore Metro and the contractors that went behind completion of this task, the work of which started in April 2007.

Diversion of utility lines and the traffic had been major challenges the personnel faced during the construction, Mr. Reddy said. With several uncharted lines posing risk, accidental snapping of a 11 Kv underground power line between Mayo Hall and Webb's Junction that was lying at a depth of 10 metres had worried the personnel.

Deputy Chief Engineer, Electrical (Rolling Stock), and Bangalore Metro's official spokesperson B.L. Yashvanth Chavan said the corporation had kept its promise of completing the civil works by August-end. The 6.7-km viaduct had 209 spans and 223 piers, including the portal pillars. Civil works of stations at Mahatma Gandhi Road, Trinity Circle, S.V. Road, C.M.H. Road, Indiranagar 100-foot road and Byappanahalli are complete by 65 per cent and the stations will be ready by December.

With the original contractor Navayuga Engineering Company going slow in the construction, Bangalore Metro offloaded work of segment launching on C.M.H. Road from the contractor and assigned the same to Gammon India. To speed up the work, it deployed additional launching girders and at one point time seven systems were working simultaneously. While track works are under way and 3.2-km track has been laid, the first train set will arrive by October 15 and the trial run begins in November. All the five train sets will arrive by December before the commercial launch.

Mr. Chavan said Fare Fixation Committee will be constituted shortly and fares will be finalised by November-end. The committee will comprise experts in the field.
