Project Organization, Planning and Documentation
This domain tests how instrumentation work is organized and documented: the instrument index, I/O list, loop drawings, cable and termination schedules, calibration records and turnover packages. Level II expects you to know which document controls which piece of information and how revision control prevents field errors.
Core rules
- The P&ID shows process relationships and instrument symbols, commonly following ISA-5.1. The instrument index lists tags, service, range and location. The I/O list defines the controller channel assignment. Loop drawings show wiring and termination details.
- Only the current revision may be used in the field. Superseded drawings are removed or clearly marked. Redline markups are transferred to as-builts through document control.
- Planning uses a work breakdown structure, a schedule with dependencies and resource loading, procurement lead times and submittal/RFI tracking.
- Change control applies to scope, tag numbers, ranges and wiring. A field change is not complete until the drawing, index and I/O list agree.
- The turnover package is indexed and signed: calibration records, loop check sheets, test reports, punch list and as-built drawings.
Worked example
A technician finds a field tag that does not match the P&ID. Stop and compare the instrument index, I/O list and latest loop drawing. If the index and I/O list agree but the P&ID is older, the P&ID may be superseded. Raise an RFI rather than relabeling the device by guesswork. After engineering approval, update the as-built and the calibration record so the tag is consistent across all documents.
Traps
Working from a superseded drawing; recording redlines on a personal copy; missing signatures on test records; allowing the I/O list and loop drawing to disagree; and treating a tag change as a paperwork-only action.
