The Real Estate Risk Assessment: An Innovative Methodology for Supporting Public and Private Subjects Involved into Sustainable Urban Interventions

Projects carried out under Public-Private Partnership (PPP) forms are increasingly being used for construction, new infrastructure implementation, urban redevelopment operations and more general land interventions. PPP projects, due to their complexity, are characterized by risks that undermine their success, for this reason risk assessment models for PPP projects are essential to their successful implementation. In this context, the research proposes an innovative real estate risk assessment methodology for supporting the Public Administration and the Private Entrepreneur involved into PPP projects. The research proposes an ex-ante real estate risk assessment methodology, based on the multicriteria Analytic Hierarchy Process (AHP) technique that can be used at different territorial scales and by both public and private parties involved in urban transformations projects. The construction of the risk index is obtained through the logical-operative framework that consists into a protocol of 7 ordered and sequential phases. The methodology turns out to be flexible and reproducible and allows for parallel analysis of qualitative and quantitative aspects that in terms of risk undermine the success of projects.
