Abstract: Cost estimating is a crucial part in Design and Build (DB) projects. The impact of inaccurate cost estimating could lead to several complications. Hence, it is very important at early stage to determine the project objectives. By applying risk analysis strategies it will help contractor to make a correct decision in cost estimating. Therefore, the objective of this study is to gain an understanding of the risk factors influencing contractor’s cost estimating on project performance in DB projects. To achieve the objective of this study, the survey questionnaire was distributed among contractor, consultant and client, that were directly involved in design and build projects. A total of 170 useable questionnaires were received and analyzed. An exploratory factor analysis was used to investigate the relationship between DB project selection and the 64 risk factors influencing contractor’s cost estimating. The results indicate that 8 group selection risk factors have the most influence contractor’s cost estimating in DB project: management risk; political risk; construction risk; system risk; variable risk; uncertainty risk; design risk and project information risk. This study help contractors more in understanding the important of allocation risk in DB project at early stage of the project begins and also creates awareness between professional bodies and stakeholders on risk impact to the project objectives.
