In today''s world، EPC (Engineering، procurement، construction) is one of the types of common contracts، especially when the state sector decides to use the skill of the internal and external contractors in designing and constructing the infra structure projects. In this paper، first we proceed to study the types of EPC contracts and state their specifications; the required precision in selecting the appropriate EPC model is emphasized، because the type of the selected model has a great impact on the duties، the rate of risk and assigned responsibility of the both sides، the price offered by the contractors، and finally the rate of taskmaster supervision on contractors'' performance.
