To accomplish a construction project successfully, it is important to manage the risk in terms of cost, time, and quality.

Risks always exist in construction projects and often cause schedule delay or cost overrun.

Risk management is a process which consists of identification of risks, assessment with qualitatively and quantitatively, response with a suitable method for handling and control risks.

The aim of this paper is to identify top major of 50 risks by contractors, owners and engineers.

Questionnaire surveys were used to collect data, based on a comprehensive assessment of the likelihood of occurrence and their impacts on the project objectives.

Also the impact of risks on cost, time, and quality, on construction project were analyzed.

Questionnaire distributed to stakeholders who are working in construction sector in Erbil City during 2014-2015, then analyzed statistically.

The results of the questionnaire indicate that the most significant risks are: inability of owner to finance the project, awarding the design to unqualified designers, poor qualifications, skills & experience of contractor and technical staff, design errors or defective design, poor qualifications and supervision of owner’s engineer, and long wait for approval of tests and inspection.

These significant risks are from four major risk factors: owner, management, contractor, and consultant.

Rise in the prices of materials, poor cost control, and design change by owner, are most significant risks that affects cost of projects.

Suspension of work, poor planning and scheduling of the project by the contractor, and slow decision making process by owner have the most significant effect on duration of a project.

While, compliance of material to specifications, awarding the design to unqualified designers, and poor qualification and supervision of owners engineer are the most significant risks that affect quality
