With a total project value of approximately $60 million (INR 400 crore), SMC was tasked with helping decongest traffic. Their solution was an 1800-meter tunnel. SMC identified the New Austrian tunneling method (NATM) as the best approach for tunnel construction. In addition to the tunnel, a 3213 meter bridge with 144 piers was part of the project scope. The bridge project was billed at lump-sum while the tunnel project was billed at item-rate.
