Mr. Sikand, this is a good question.
The reality is that irrespective of the way that communities choose to procure infrastructure, the private sector is always involved. The advantage of a public-private partnership over traditional procurement is that the private sector as a consortium takes on responsibility for the design, the construction, some of the private finance, and the maintenance of the asset over a period of 25 to 35 years.
Governments enter a fixed-price contract with these consortia, which take on the risks associated with design and construction, amongst other risks. As you may know, with traditional procurement, many projects come in well over budget and way behind schedule. The nature of the contractual arrangement with P3s precludes that, because the private sector has a responsibility for those cost overruns, and is held accountable for them, and not government, they are therefore very focused on ensuring that projects do come in on budget, and on time.
