A public private partnership is a government or private venture service which is operated and funded by a one or more private venture and with partnership of government. In this procurement method there is one contract in between the government authority and public authority. In this contract the private party provides the public service or project and assumes substantial financial, technical, and operational risks in the project. In this project the investment is made by the private companies and the cost of using the service is paid by the users of the service. The cost of providing the service is borne by the government fully or in part. In the civil structure the government provides the subsidy to such projects as well (Davies, Nikolas, and Erkki Jokiniemi, 2008). This subsidy will be in form of one time grant for any civil infrastructure project, for example pedestrian foot bridge. There are usually two fundamental drivers of this PPP procurement model. One is the use of expertise and efficiencies of the private sector by government sector. Second, the government sector can also provide public services and there is no need of the borrowings by the government. The fund in this procurement model is paid by the private sector and then the private sector gets the investment return from the users of the service (Rozhanskaya, Mariam; and Levinova, I. S. 1996). There it defined a time limit for the finance collection by the private companies so that the investment can be recovered.
