Feasibility study
The FEE is basic engineering which comes after the Conceptual design or Feasibility study. The FEE design focuses the technical requirements as well as rough investment cost for the project. The FEE can be divided into separate packages covering different portions of the project. The FEE package is used as the basis for bidding the Execution Phase Contracts (EPC, EPCI, etc) and is used as the design basis.
