Yes; you are right. We follow 2 types of checklists; one is for mechanical completion (normally referred to as Punch-list) and other before commissioning of a plant. The punch-list for Piping Mech. Completion is prepared by contractor and checked by Project Management Consultant (PMC)/ Owner; to be liquidated by Contractor. The checklist before commissioning is by Client Operations/ other groups/ PMC and the completion of systems is recorded over a few designated 'Handover' formats. It is highly desired that the total piping be got checked from Mechanical/ Process/ Operations/ Instrument viewpoint.

Some of the general points of check wrt Isometric/ GA drawings are: Supports check
Welding of Joints, slag removal etc.
Valves, location & their direction wherever applicable Venturi/ instruments/ orifices/ other fittings; Pipe condition (say dents/ pitting etc if at all) Drains/ vents
Special notes with respect to P&IDs
Specific checkpoints related to special piping such as Slopes, Jacketing connections etc.
Piping completion including branching etc wrt drawings/ General arrangements.

Regards,

The pdf file referred to below is all about pipe modeling. A field checklist prior to commissioning or mechanical acceptance is normally term as punchlist. Normally this is part of the project deliverables prepared not by Owner but rather by the Contractor.

The norsok site may hve something on this. If not email me and I'll send you a copy of our commissioning manual pertaining to Piping (if i still have it - not sure)Normally this activity fall unders the responsibility of your QC/QA (local law may require Inspector signoff) and not Operation.
