All forms of co-operation between the public and private sectors with the aim of providing some public services or securing the infrastructure to meet certain public needs is unified under the concept of public-private partnership. PPP allows the public sector to maintain control over the provision of public services. Resources and knowledge of the private sector make delivery of public services more efficient and better quality. Public sector partnerships with a private partner are justified if the public sector expenditure analysis shows that a public-private partnership model will generate value for money based on savings for taxpayers. One of the main characteristics of public-private partnerships is the division of risk between a public and a private partner in a way that the private partner allocates those risks to which he is capable of being more efficiently managed. Some of the benefits of public-private partnerships are the reduction of project lifecycle costs, accelerating infrastructure construction, better risk sharing, improving service quality, and more. One of the disadvantages of this model is considered a natural conflict between the public and private sector goals. The contractual and status form of public-private partnerships are two basic forms of realization of the same, and their modalities are numerous. The most prominent models of contractual forms of public-private partnerships are the concession form of PPP and the private financial initiative (PFI model). To date, 14 projects have been realized in the Republic of Croatia by the PPP model. In this paper, one of them is considered, namely the construction of gymnasium and hall in Koprivnica.
