The Bangalore Metro Rail Corporation Limited (BMRCL) in-house team to prepare a detailed project report (DPR) on connecting Namma Metro to the Kempegowda International Airport (KIA). This was confirmed by BMRCL managing director Pradeep Singh Kharola. BMRCL now believes it has in-house capability to take up the study. Yet, a couple of crucial surveys for the DPR is still being outsourced.

The 29-km project, part of Namma Metro Phase II (B), will be an extension of Phase II from Nagawara. The alignment passes through Hegde Nagar, Jakkur and Yelahanka before it connects the airport.

The DPR will include details of the traffic demand analysis, civil engineering work, number of stations, maintenance depot, land acquisition, environment and social impact assessment, estimated capital cost, operations and maintenance cost and risk factors, among others.

Crucial portions of the DPR such as the geotechnical investigation and the differential global positioning system, topographic, land and property survey will be handled by external agencies.

Tenders for this have just been floated. The tender document indicates the deadline for the DPR. The external agencies have been given six months from July 15 (the closing date for bidding) to submit their findings.

This will not be the first time that the BMRCL is preparing a DPR inhouse. The DPR for the proposed line from Central Silk Board and KR Puram was prepared by its own team. It was also prepared in a record time of one month as the geotechnical investigation and various other survey reports were already available.

Authorities have indicated that work on the airport link will begin simultaneously with Namma Metro phase-2 work. The officials said that the present alignment to the airport involves less land acquisition as it runs parallel to Ballari Road (NH 44), which is the route to the airport.

Regarding the funding of the airport line, Bengaluru Development Minister KJ George indicated that financial support would be sought from the Centre. Although the government did not pick any of the nine routes suggested by RITES, a government of India undertaking, it is estimated that the 29-km link could cost not less than Rs 4,000 crore.
