A TCO Tomorrow, an Unsigned Record of Completion
An eight-story mixed-use building is chasing a temporary certificate of occupancy for floors 2 through 8. The final acceptance test has not been witnessed by the AHJ. The record of completion is on site but incomplete: no signatures, no battery calculations, no test records attached. As-builts show a "typical floor" plan with no device addresses. No site-specific program has been delivered and no reload procedure documented. No owner training has occurred. Separately, an architect's bulletin issued three weeks ago added corridor detectors on four floors; that work is installed but no change order has been executed. The GC wants you to sign the record of completion today so the TCO can issue tomorrow.
1. Can you sign the record of completion to support the TCO? What is the sequence?

No. The record of completion is your certification that the system was installed per the design, tested as required, and is operational - and it is signed after the acceptance test, not before. Signing to unblock a TCO converts a scheduling problem into a false statement that carries your name.
What you can do is what NFPA 72 contemplates for phased occupancy. Define the portions of the system serving the floors to be occupied, complete the acceptance test on those portions with the AHJ witnessing, and issue a record of completion limited expressly to those portions, with the remainder excluded and scheduled. Get the AHJ's written concurrence on the phasing plan before the test day, and make sure the TCO request references a partial acceptance and not a final one.
If the AHJ will not accept a phased approach, the TCO waits. That is a decision for the owner and the building official, not something you can paper over.
2. Which documentation gaps must close, who provides each, and how do you use them at substantial completion?

Everything on that list is a deliverable, not a courtesy:
- As-built drawings - "typical floor" with no addresses is not as-built. Each floor needs device locations, addresses, circuit routing, and the riser.
- Site-specific software - the owner must receive the program, the documented means to reload it, and version/access information; without it they are permanently captive to one vendor.
- Record of completion - signed, with testing records and battery calculations attached.
- O&M manuals - manufacturer's instructions and the battery/voltage-drop calculations.
- Owner training records and a written inspection, testing, and maintenance program with the frequencies and the first-cycle dates.
Assign each item an owner - contractor, designer, or you - with a date, and hold substantial completion acceptance against that list. Refusing to sign until they exist is the deliverable, not obstruction.
3. How do you handle the corridor detector change order?
Read the worked answer
Treat it as a scope and design change, not a field fix.
The bulletin changes the NFPA 72 coverage and the sealed design. Get the revised drawing and the designer's written direction - a bulletin markup is direction, a verbal "add them" is not. Then document impact: cable, devices, added loading on the power supply and NACs, revised battery and voltage-drop calculations, and the extra acceptance testing those additions require.
Establish the entitlement question early: if the added detectors are required by code, this is usually a design-error claim between owner and designer, not an extra to the owner; if they are betterment, it is a straight change order. Submit, get written approval, install, and update the as-builts, device list, and record of completion before the acceptance test.
Log the change so the final record states what is actually on the wall. An installed but unapproved and undocumented change is the item most likely to be discovered by someone else, at the worst time.
