Front-end loading

Front-end loading (FEL), also referred to as pre-project planning (PPP) or front-end engineering design (FEED), is the process for conceptual development of processing industry projects. Examples of processing industry are upstream, petrochemical, refining, pharmaceutical.

Front-end loading is including robust planning and design early in a project's lifecycle (i.e., the front end of a project), at a time when the ability to influence changes in design is relatively high and the cost to make those changes is relatively low. It typically applies to industries with highly capital intensive, long lifecycle projects (i.e., hundreds of millions or billions of dollars over several years before any revenue is produced). Though it often adds a small amount of time and cost to the early portion of a project, these costs are minor compared to the alternative of the costs and effort required to make changes at a later stage in the project.

It also typically uses a stage-gate process, whereby a project must pass through formal gates at well defined milestones within the project's lifecycle before receiving funding to proceed to the next stage of work.

FEL Stages

It is common industry practice to divide front-end-loading activities into three stages: FEL-1, FEL-2, and FEL-3. For each stage, typical deliverables are listed given below :

FEL-1	FEL-2	FEL-3
Material balance Energy balance Project charter	Preliminary equipment design Preliminary layout Preliminary schedule Preliminary estimate	Purchase-ready major equipment specifications Definitive estimate Project execution plan Preliminary 3-D model Electrical equipment list Line list
