Other project documents

This section describes the other documents that are part of the project deliverables.

Engineering lists

Engineering lists are crucial within the project, as they list and quantify various components. Engineering lists include the following:

• Equipment list for cataloging all equipment items

• Line lists that detail materials such as piping and insulation

• Instrument list for all process instrumentation

• Motor list that catalogs the motors

• I/O list for control system components

Initially issued in a preliminary form during the early stages of the design, these engineering inventories become particularly valuable towards the end of the design. At this stage, these engineering inventories contribute significantly to the formulation of the final cost estimation for the project.

Datasheets

These documents include specific datasheets for each piece of equipment and vital instrumentation such as analyzers, control valves, and safety relief devices. During the initial phase, these datasheets generally cover only the fundamental process parameters (such as capacity, flow rate, and pressure) and basic metallurgical specifications, which sometimes are known as Process datasheets or Process Instrument datasheets.

However, in the later stages, these datasheets are expanded to include more detailed information, including model numbers, connection dimensions, and unique features.

Schedules

The schedule for the project is a critical document that guides the entire process. Early in Front-End Loading (FEL), it is important to establish a preliminary timeline to assess the engineering workload, schedule for the delivery of equipment requiring long lead times, and overall construction timeline, which includes crucial completion dates, milestones, and potential periods of shutdown.

Towards the end of FEL, you should develop a more detailed and comprehensive schedule to form the groundwork for the project's execution, stating from a detailed design to construction.

Cost estimates

You should formulate the estimates of the total cost of the project at the conclusion of each Front-End Loading (FEL) phase, considering a typical three-phase FEL process. These estimates are crucial for budgeting and financial planning as the project progresses through its various stages.
