Cost overrun is one of the major challenges faced in construction projects around the world due to various causes which reflect different impacts on project completion with the planned cost. This issue is also common in the Sultanate of Oman, especially in government projects and residential buildings and that will affect the development of the country. The percentage of exceeding the cost of the construction project is a variance from one project to another. The main objective of this study is to recognize the factors influencing cost overruns in the Omani construction projects, evaluate the impacts of project cost overruns in the Omani construction projects, and develop a strategy of mitigating measures for cost overruns that can be implemented in the future to control the cost overrun. The methodologies of this study are qualitative and quantitative methods, interviews with experts in the construction industry and questionnaire surveys.

The Questionnaire survey has been distributed to private and governmental organizations related to construction projects involving engineers, contractors, consultants, and clients as well as the interviews.  The expected results from this study are explore the major factors affect the cost overrun in the Omani construction projects, the impacts of project cost overrun in the Omani construction projects, strategy of mitigating measures for cost overruns.
