Sharing risk/responsibility in a Public Private Partnership
Public Private Partnerships (PPP) enable public administrations to share the tasks and risks of planning, realization and operation together with private partners in joint projects. Accordingly, the Hernals District Development Commission decided to promote the façade greening measure in the framework of "Public Private Partnership" models. With the expertise of the Viennese Environmental Protection Department - MA 22 - and the support of the district as well as the local area, a remarkable green oasis was created in the form of a green façade at a private house in the Ortliebgasse. The collaboration has proved equally valuable for the project and the public and private partners involved.
The most important success factor was the cooperation of the actors. The costs for the planning and construction were shared by the district and the environmental department MA 22 and the private owner, who is responsible for the maintenance. The agreement was based on an informal contract between the private owner and the district.
The fulfillment of public tasks is traditionally assigned to public administrations, making it challenging to break from this historically ingrained model. The diverse requirements of modern societies however, show that a strict separation between the public and private sectors is no longer feasible. New approaches such as Public Private Partnerships (PPP) show that it is quite advantageous for selected projects to share the tasks and risks of planning, realization and operation together with private partners. While offering many benefits, it should be noted that the planning and administrative efforts of coordinating a PPP are relatively high. These can, however, be simplified with experience and even save costs and resources in the longer term.
