Front-end loading (FEL), also referred to as Front-End Engineering Design (FEED), Front End Planning (FEP), pre-project planning (PPP), and early project planning, is the process for conceptual development of projects in processing industries such as

''Front-end loading'' includes 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. The quality of front-end planning can be improved through the use of
PDRI (Project Definition Rating Index) as a part of the stage-gate process.
Front-end loading is usually followed by
detailed design or
detailed engineering.
FEL Stages
It is common industry practice to divide front-end-loading activities into Five stages. For each stage, typical deliverables are listed given below :
# FEL 0 - Conceptualization: The costs associated with the FEL 0 stage typically represent a small percentage of the total investment, as they focus on the initial evaluation and identification of the feasibility of the project. It could vary between 1% and 5% of the total investment.
# FEL 1 - Represents Feasibility Evaluation: The costs at this stage are higher than in FEL 0, but still a relatively small fraction of the total investment. It could range between 5% and 15% of the total investment.
# FEL 2 - Preliminary Design: As the design stages progress, costs usually increase. It could represent between 10% and 20% of the total investment.
# FEL 3 - Basic Design: The costs associated with basic design tend to be more significant. It could range between 15% and 30% of the total investment.
# FEL 4 - Project Execution: This stage usually represents the majority of the total investment, since it involves the construction and start-up of the project. It could represent between 50% and 70% or more of the total investment.
Another FEL methodology splits the project into four phases:
# FEL-1: Options Study or Index Engineering. This answers the question, "what are my options to achieve my project goals?". For example, in the processing of
nickel laterite ore, it might be possible to build either a
pyrometallurgical
Pyrometallurgy is a branch of extractive metallurgy. It consists of the thermal treatment of minerals and metallurgical ores and concentrates to bring about physical and chemical transformations in the materials to enable recovery of valuable ...
or
hydrometallurgical processing plant. This stage would study both options and recommend the best one based on the specific project requirements.
# Gate 1: Option Selection. The
project owner
In project management, an executive or project executive is a person who has ultimate responsibility for a project, and is a role defined in the recognized project management framework PRINCE2. It is appointed by the customer during the start of th ...
selects which FEL1 option will be developed further, based on input from their engineers.
# FEL-2: Feasibility Study or Conceptual Engineering. The selected option is developed up to a pre-defined level of detail not yet sufficient for construction and operation, but enough to develop a cost estimate, a schedule estimate, and to make any critical decisions that will influence the final design of the plant.
# Gate 2: Approval for Basic Engineering. Based on the conceptual design and cost and schedule estimates, the project owner will decide whether or not to proceed with the plant.
# FEL-3: FEED (Front-End Engineering Design) or Basic Engineering. The engineering team will now fully design the plant, including the exact specifications for how it will be
constructed,
commissioned, started up, and operated. The proposed plant will now have a detailed cost estimate and construction schedule.
# Gate 3: Approval for Construction. The project owner will give their approval for building the plant as designed by their engineers.
# FEL-4:Project Execution and Detailed Engineering. Materials procurement and construction will begin. This stage includes all activities until the plant is started-up and regular operations begin.
