An engineering design approach much used in process and power plant projects to control project expenses and thoroughly plan a project. It may also be referred to as Pre-project planning (PPP), front-end loading (FEL), feasibility analysis, or early project planning. The FEE is basic engineering which comes after the conceptual design or feasibility study. Front-End Engineering focuses on technical requirements and identifying main costs for a proposed project. It is used to establish a price for the execution phase of the project and evaluate potential risks. It is typically followed by Detailed Design (or Detailed Engineering). The FEE package is used as the basis for bidding the execution phase contracts (EPC, FPTK etc) and is used as the design basis. Project lenders will typically look for the successful EPC contractor to confirm that he is satisfied with the design information supplied to him in the FEED study (known as a “design wrap”).
