Build-Operate-Transfer (BOT): It is a conventional PPP model in which the private partner is responsible to design, build, operate (during the contracted period) and transfer back the facility to the public sector.

Build-Operate-Lease-Transfer (BOLT): In this approach, the government gives a concession to a private entity to build a facility (and possibly design it as well), own the facility, lease the facility to the public sector and then at the end of the lease period transfer the ownership of the facility to the government.
