Out of tolerance anchor rods bill you by the crane day
The crane is rigged at six in the morning, the rods are out of tolerance, and nobody on that site wants to sign a ticket before your crew starts drilling.
Your start date is controlled by a concrete sub's tolerance and your biggest daily cost is a rented machine that doesn't care why it is sitting. No other trade commits equipment of that size before the predecessor's work has been verified by anyone. That's why equipment cost on a steel job has to be coded by day and by job, so a standby day is visible the week it happens and not at year end.
The size of it
Idle crane days plus a second mobilization run into tens of thousands on a mid size job. Unticketed, that cost sits in equipment with no job and no change order attached, and at month end it reads like your crane is too expensive.
Erection can't start until foundations are cured, surveyed, and anchor rods sit within AISC 303 tolerance. Your erector finds out of tolerance rods the morning the crane is rigged, because nobody gives you a survey of somebody else's concrete a week ahead. Crane rental bills by the day or the month with mobilization and demobilization each way, so an idle day burns at full rate against zero production. The fix, field drilling, repair plates, and EOR sign-off on the repair, is change order work, and it has to be ticketed while the crew is standing there or it gets absorbed.

What structural steel owners ask
Who pays for crane standby when anchor bolts are out of tolerance?
The crane is rigged at six in the morning, the rods are out of tolerance, and nobody on that site wants to sign a ticket before your crew starts drilling.
What does it cost?
Idle crane days plus a second mobilization run into tens of thousands on a mid size job. Unticketed, that cost sits in equipment with no job and no change order attached, and at month end it reads like your crane is too expensive.
What do I do first?
Require a written anchor rod survey from the GC before crane mobilization, and put the date you need it on the two week look ahead.
What are structural steel contractors supposed to be making?
Structural steel runs 23% gross margin, 15% overhead and 8% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits 1 points above it. The CFOS target is 10%.
Which part of the system fixes it?
The step is number 02, equipment cost basis. A true internal rate per machine covering ownership, maintenance, fuel, and transport, charged to the projects that used it. It comes from chapter 2 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.
