The design standards provide ready to use examples and design dimensions for equipment, piping and other disciplines. These standards are usually not part of the auditable section of the QA system. The focus of the guides is primarily related to project execution because the procedures are written from the perspective of an Engineering Contractor.
The below listing gives an indication of the available procedures. Use Library Menu navigation bar at the left to view the public procedures on this website or use this link to go directly to the QA system documents >
