Now CORE office of BBS is shifted to Bengaluru I think so their are lot of RE works in South which this office handles.. Same way Gadag Bagalkot 93 km will be coming under CORE only I think as RVNL only takes Trunk and Port Connectivity routes RE so Hubli Haveri also under CORE Solapur Gulbarga Hospet Bhanapur Hubli Alnawar come under RVNL and Miraj Londa PDCIL it seems..
