Abstract
High quality infrastructure is a must for rapid economic development and requires sustained investment. It includes highways, railways, ports, bridges, hospitals, power plants, tunnels, and municipal facilities like sanitation, waste management, potable water supply, and other facilities serving public needs. Developing countries face shortage of government or public funds and are generally inadequate in addressing the infrastructural needs of the country. It is highly difficult and often impossible by governments in their own capacity to bring together all the infrastructure elements. This realization has brought together the public and the private sector in a mutually beneficial relationship in the form of Public Private Partnerships [PPPs].PPPs are an effective tool for bringing private sector efficiencies in creation of economic and social infrastructure assets and for delivery of quality public services. PPP is seen as a financing mechanism for bridging the demand supply gap in terms of private capital and experience. Several schemes have therefore provided an increasingly popular vehicle to move towards infrastructure development. PPPs have become the preferred mode for construction and operation of commercially viable infrastructure projects in sectors such as highways, airports, ports, railways and urban transit systems. In this paper the construction of Greenfield Bangalore International Airport is taken as a case to study and understand PPP
