A Decision Support Methodology for Assessment of Construction Project Risks

摘要

The aim of this paper is to develop specialized approaches for identifying and assessing construction project risks. An approach called 'Three-dimensional Risk Identification' is developed basing in a combination of three parameters: risk typology, project phases and stakeholders. Then, a framework is proposed for their assessment and prioritization basing on multiple criteria decision making methods to define the notions of 'aggregate impact' and 'Weighted Criticality'. The outcome of this method is a three-dimensional framework that lists and classifies the construction project risks. It allows the project manager to detect the critical risk owners that must be overseen and monitored, to identify the project phases presenting a risk concentration and then to define another type of project critical path analysis. The notion of weighted criticality provides to the project manager a support for the construction project risks prioritization that overcomes the limits of the classical notion of criticality.
