Front End Loading (FEL) is a process of scope definition and risk assessment known as a stage-gate process.  Through creation of conceptual engineering document packages, which often include P&ID’s, Equipment Specifications, Equipment Layouts, Electrical Schematics, Instrument Lists, and others; Perigon can develop project scopes from which a budgetary project cost estimate can be prepared.   The progression of stage-gate engineering phases is employed whereby project definition is advanced from conceptual (FEL-1), to feasibility (FEL-2), to preliminary or definition phase (FEL-3), with cost estimates of expected improved accuracy being performed at each phase.
