  • Time extension of DRIP was requested during 14th TC meeting

at Cochin on account of late work awarded.

  • 2 Y

ear extension for all IA’s was agreed during 14th TC meeting to accommodate projects with long construction period.

  • M oWR,RD&GR concurred the proposal of time extension by

two year in Nov 2016 & directed CWC to submit the proposal to DEA/ World Bank

  • CWC has submitted proposal of time extension to DEA.
