No SC CORE office I guess closed and now Chennai looking projects of SC office and Bhubaneshwar office shift to Bengaluru so all CORE related RE work of Karnataka under Bengaluru office now.. These changes are done for better implementation of projects in Karnataka region..You saying about SC RVNL office which handles only trunk and port connectivity routes like Vasco GTL Guntur and Pune Wadi Guntakal Renigunta, Guntakal Yelhanka etc.. I am saying about CORE office and RE works pertaining to CORE.
