The Ministry of Road Transport, Highways and Shipping is, henceforth, planning to undertake national highway projects on EPC (engineering-procurement-construction) model instead of PPP (public-private partnership) mode. The EPC vs. PPP issue has been widely debated among road builders and in public forums. The efficacy of PPP projects has been questioned owing to frequent delays in implementation and commissioning, and other challenges on the ground. This has brought EPC back in favour among project developers.
