Five companies have submitted bids for the electrical and mechanical contract E&M-6 of the 57-km-long Blue Line of Bangalore Metro after the Bangalore Metro Rail Corporation (BMRCL) opened the technical bids.

Currently under construction as part of Bangalore Metro's Phase 2A (ORR Line) and Phase 2B (Airport Line) projects, this new line will connect Silkboard, KR Puram and Bengaluru International Airport via 30 stations along the Outer Ring Road and NH-44 national highway.

The scope of this critical systems contract includes electrical and mechanical works at 28 stations, two traction substations (TSS) and a cut-and-cover section of approximately 718 metres adjacent to Yelahanka Air Force Station. Electrical and mechanical works at Airport City Metro Station (also known as KIA West Station) and KIA Terminals Station will be included in a separate contract.

BMRCL had floated a tender for package E&M-6 in September 2024, with an estimated cost reported to be around Rs 1.83 billion, with a delivery period of 1.5 years.
