A passage on Infrastructure and PPP

Introduced in January 2016 to revive investments in road infrastructure projects, ____ has seen good initial success. It is a mix of the EPC (engineering, procurement, and construction) and BOT (build, operate, transfer) models. Under the EPC model, NHAI pays private players to lay roads. The private player has no role in the road’s ownership, toll collection or maintenance (it is taken care of by the government). Under the BOT model though, private players have an active role — they build, operate, and maintain the road for a specified number of years — say 10-15 years — before transferring the asset back to the government.
