The Importance of Drawings - Part 2

The Front End Design Electrical Drawings

The project desgin process is a dynamic evolution that begins with a concept design and progresses through to construction and operation.
The front end design phase is sometimes identified as FEED (front end engineering and design). A preliminary to FEED may be identified as Pre-FEED or FEL (front end loading).

The type of drawings would be single line diagrams, GIS layout, typical installation drawings, SCADA network architectures, block diagrams and schematics.

The drawings are important because they may be used:

• To present high level options for technical evaulation and budget estimation
• As a basis for design optimisation
• To allow interface with civil, mechanical and process designs
• To allow interface with third parties

 

During formulation of the design, what-ifs and options may be considered by modifing drawings.
The drawings evolve as the design progresses, until the FEED is completed. The drawings form part of the formal documentation to be presented as part of the FEED study. If the project continues, they form the basis for detailed design. If the project does not continue, they become reference material which may be used on future projects. Either way, the drawing represent intellectual property.
