The use of EPC contracts has grown at an unprecedented rate in recent years, and almost every construction and contracting project deals with this contract.

The first and perhaps most important feature of EPC contracts is the transfer of project execution risk to the contractor. Since the design, equipment supply, and construction are completely interconnected, it is in the employer's interest to place the set of these elements on a specific contractor and to ask him for the responsibilities and possible damages of the execution.

Purchasing, supply and logistics phase (Procurement):

At this stage, the items, equipment and materials needed to implement the project are purchased, prepared and manufactured, and finally delivered from individual contractors or sellers.

At this stage, project progress is usually planned and controlled based on the purchase and cost steps (in some cases time or a combination of cost and time) required to complete the purchase.
