ABSTRACT
The use of the Public Private Partnership (PPP) models for project delivery, especially for infrastructure projects, has increased over the past decades. Their growing economic importance for society has triggered research interest with respect to private involvement in project delivery and financing of public infrastructure and social projects. A Public Private Partnership is a legal framework under a PPP act, defined as a relationship involving private capital in a public project. These projects are in the public interest, based on relationships between public and private partners and focused on the construction, maintenance and operation of public infrastructure and the associated provision of commercial and other public services or activities. PPP structures are typically more complex than traditional public procurement. There are often more parties involved in a project, the financing costs of PPP are generally higher and the different parties have to share the risks involved in a PPP.
