The long-term nature of Public Private Partnerships provides significant legal and administrative challenges. The success of a PPP contract depends equally on a sound contractual framework and a true ‘partnership’ relationship. Roger Quick of Gadens Lawyers outlines the requirements for successfully managing these contracts. The success of a public private partnership depends on a successful relationship between the participants to the project. This alone will allow the participants to work together to achieve the project’s objectives: the end users of the services should receive quality services; the authority should receive value for money and the private sector contractor should receive a reasonable rate of return on investment. These are potentially conflicting objectives. A successful partnership requires a simple framework upon which the parties can build their relationships. The use of relationship contracting in the Australian construction industry suggests the model framework.
