ITP registers look complete in a progress meeting. Green cells in a spreadsheet. Percent complete on a dashboard. The commissioning window is where the register meets reality — when AHJ sign-off, vendor witness holds, and occupancy permits converge on a fixed calendar.
Aggregate completion hides blocking items. Six unsigned ITPs may represent zero schedule risk in a summary chart and maximum risk in a jurisdiction that will not issue occupancy until specific inspections are closed. Owner-side teams need the register mapped to AHJ submission requirements — not just to construction completion.
In the commissioning engagement that surfaced this failure mode, the owner's team knew some ITPs were late. They did not know the late items blocked permits. Nobody had run the crosswalk between the ITP register and the AHJ schedule since kick-off. Three weeks of assumed progress became three days of recoverable options.
Map ITP IDs to permit dependencies. Assign a single owner-side accountable party for register integrity — not distributed across three contractors. Run weekly status against commissioning gate criteria, not against construction percent complete. If your program is eight weeks from commissioning and the crosswalk does not exist, that is the engagement.
