Lack of coordination between various departments while undertaking road-digging work has proven costly for the APTransco on multiple occasions.

The fresh attempt at excavation by the Water Board contractor, which has resulted in a conked-out cable connection between Moulali and Chilkalguda, will cost the Corporation nearly Rs. 1.5 lakh.

In May 2011, the same cable was damaged after being struck by the Water Board contractor’s earth moving machine. Summer loads had to be adjusted on other feeders, resulting in widespread blackouts.

“We wrote to the Water Board officials then, asking them to inform us before undertaking any digging work. They have not done it this time too,” said Superintending Engineer (Operations and Maintenance) N.Bhaskar.

The APTransco has, however, set guidelines on road digging, with information passed on to the GHMC, Water Board, CPDCL and BSNL, which might have their utilities underground, he said.

More precautions are followed while laying cables. Depending on the stretch to be dug up, either the GHMC or Roads and Buildings, or Cantonment or NHAI is informed, and due charges paid.

An initial survey details conducted to take stock of the visible obstacles on the stretch, followed by a detailed survey.
