Links Fail in November, Cable Was Crushed in April
Forty links fail at certification in November. The HVAC crew crushed them above the ceiling in April and demobilized in June.
Most trades install work that stays visible until somebody accepts it. Your product disappears above a finished ceiling within weeks and doesn't get proven for a year, which makes telecom the only trade on the job that finds damage after every possible defendant has left the site. The months between install and proof are where the money goes.
The size of it
Hundreds of unbudgeted crew hours hit at the moment the job should be closing and turning cash-positive, and the closeout delay pushes retention release out another quarter.
By the time the tester tells you, the evidence and the responsible party are both gone. Your cable lives above ceilings and inside walls for six to eighteen months between rough-in and trim, with sprinkler, HVAC, grid, and drywall crews working around it and nobody watching. Permanent link certification runs at the very end, so a bend radius crushed in the spring surfaces the week you thought you were closing out. Without dated photos and a signed rough-in inspection, the backcharge doesn't stick, and the repull, the re-termination, and the retest come out of your pocket. Final payment is gated on passing results and manufacturer warranty registration, so walking away from the failures isn't an option either.
Three moves, in order

What telecom owners ask
Another trade damaged my cable above the ceiling who pays for the repull?
Forty links fail at certification in November. The HVAC crew crushed them above the ceiling in April and demobilized in June.
What does it cost?
Hundreds of unbudgeted crew hours hit at the moment the job should be closing and turning cash-positive, and the closeout delay pushes retention release out another quarter.
What do I do first?
Photograph and date every tray run, J-hook run, and wall penetration before the ceiling closes, filed by area and sheet number.
What are telecom contractors supposed to be making?
Telecom runs 22% gross margin, 15% overhead and 7% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits right on it. The CFOS target is 10%.
Which part of the system fixes it?
The step is number 08, standards and accountability. Five hours a month of owner time, spent ahead of the work. It comes from chapter 8 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.
