Holistic approach for treatment of accidental hazards during conceptual design of bridge - A case study in Sweden

Research output: Contribution to journalArticle


The control of risks in engineering design is, for most conventional construction projects, achieved through the use of design codes. However, relying on design based on code-compliance can lead to situations where risks are overlooked or inadequately treated; a complementary approach is needed. In this paper, a holistic risk-informed approach for the treatment of accidental hazards during the conceptual design of bridges is considered and a framework for such an approach is provided. The treatment of these design situations is incompatible with current codified approaches. Although risk assessments are commonly used in the design of large scale infrastructure projects, such approaches are rarely used for more common bridge designs. The assessment procedure, applicable for more conventional bridge projects, is described and some background information is provided that is useful for applying the proposed approach in practice. To illustrate the application of the proposed approach in practice, a case study of a bridge construction project in the west of Sweden is considered in which the approach is applied.
