Dead Openings: Division 8 Buys It, You Eat the Re-Trip
You roll a crew for forty doors, nine have no power transfer, and you leave. Nobody buys those hours back because you don't hold the hardware contract.
Electrified locks, electric strikes, power transfer hinges, and EPTs are specified, bought, and installed under Division 8, and they do nothing at all until you terminate them. If a hollow metal frame shipped without the factory prep, or the hardware supplier value engineered an electrified function down to a mechanical one, or the wrong transfer device went in, the opening is dead and you found out by driving to it. You don't have a contract with the hardware supplier, so there's no backcharge path, and the GC files the whole thing under coordination.
The size of it
You take three to six unbudgeted re-trips per project, typically 40 to 80 field hours, on openings this trade neither buys nor controls. Those are real labor hours with no change order behind them.
Walk the openings against the door hardware submittal before you schedule a termination crew, and make that walk a priced line in the estimate so it stops hiding inside labor. Right now the dead opening gets discovered at the door with four techs standing there, which turns somebody else's coordination failure into a labor overrun on a job you bid correctly. Your job cost has no code for it, so the hours pile into general termination labor and the estimate takes the blame. Once re-trips carry their own cost code charged by door number, you can put a count and a dollar figure on the table at the monthly meeting. That's the only form of this conversation that has ever produced a change order.
Three moves, in order
Step 06: Project management
Billing dates, change orders, and notices, run as standards that hold without anyone chasing them.

What security systems owners ask
Who pays when door frames aren't prepped for electrified hardware?
You roll a crew for forty doors, nine have no power transfer, and you leave. Nobody buys those hours back because you don't hold the hardware contract.
What does it cost?
You take three to six unbudgeted re-trips per project, typically 40 to 80 field hours, on openings this trade neither buys nor controls. Those are real labor hours with no change order behind them.
What do I do first?
Pull the door hardware submittal and build a one-page opening matrix with door number, frame prep, transfer device, lock function, and who terminates.
What are security systems contractors supposed to be making?
Security systems runs 22% gross margin, 16% overhead and 6% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits 1 points below it. The CFOS target is 10%.
Which part of the system fixes it?
The step is number 06, project management. Billing dates, change orders, and notices, run as standards that hold without anyone chasing them. It comes from chapter 6 of CONTROL: The Construction Financial Operating System.
Josh Luebker ran commercial construction projects before he ran the numbers behind them, on data centres, military bases, hospitals, and high-rises. He wrote CONTROL: The Construction Financial Operating System, which is an eight-step framework for commercial subcontractors, and it publishes on October 1, 2026. He is a master electrician who moved into the office and kept the field vocabulary.
Sulphur Prairie Operations LLC maintains the benchmark reference behind these figures. Every edition is reconciled against the newest CFMA survey release before it publishes here. Where a figure changes between editions, the older edition keeps its year in the title so a citation to it stays correct.
