01The Challenge
A newly constructed alkylate production facility was ready to commission and had no commissioning inventory. The contractor had already mobilized a full team of inspectors, but there was no organized way to track tagged items against the system boundaries drawn on the P&IDs.
The manual fallback — field teams scratching IDs off drawings by hand — would have burned weeks of labor and introduced error into the one register the whole commissioning effort depended on.
The cost of waiting: three to four weeks of delay with inspectors already on site and on the clock.
02The Approach
250 AutoCAD P&IDs were loaded into IDP, which identified the existing symbology and associated labels across the full drawing set.
Output: digitized drawing setIDP's hierarchy tool selected every tagged element and grouped it by commissioning system — equipment, instrumentation, piping, relief devices, and specialty items.
Output: system-grouped inventoryThe hierarchy was exported and post-processed into a system-based commissioning register, formatted for immediate field use.
Output: field-ready register03What Changed
Inspectors already on site began field verification on schedule instead of waiting on paperwork.
Every tagged element captured from the drawings, rather than whatever manual review happened to catch.
The register mirrors the commissioning system boundaries the team actually works to.
The same extracted structure carries forward into operations and maintenance.
