For the 4.7 km tunnel Package C-4 of the 121.74 km Haryana Orbital Rail Corridor (HORC) project, the Rail Vikas Nigam (RVNL) has come out on top as the lowest bidder.

The Roz-Ka-Meo Industrial Area in Sohna is close to the construction of twin tunnels through the Aravalli Mountains between chainage 24.880 km and 29.580 km.

The New Austrian Tunneling Method (NATM) and the cut-and-cover technique will be used to build the tunnel.

The project's implementing organisation, Haryana Rail Infrastructure Development Corporation (HRIDC), issued an unannounced procurement call in November 2022 for the construction of the C-4 package on an EPC basis.

Six bidders were in the running when the technical bids were opened in February. They included IRCON International, RVNL, ITD Cementation India, APCO Infratech, Gawar Construction, and Dilip Buildcon.

RVNL's bid of Rs 10.88 billion has been determined to be the lowest.
