Outrigger Damage Comes Back Netted Off Your Next Check
A letter reaches you in June about a driveway your outriggers cracked in April, and the amount comes straight off your next check.
Trades with a warranty tail come back and repair their own work. You've no work to come back to, the slab belongs to somebody else, and your exposure is what a 70,000 pound machine did to the property around it. That means the whole thing gets settled by a letter and a deduction, with no punch list, no RFI, and no chance to price the repair yourself.
The size of it
Recurring four-figure deductions never touch the job cost record, and they never get coded to the pour that caused them, so no margin report you look at includes them.
The tail on a pour is property damage, and it hits as a deduction 30 to 90 days after you already got paid. Outrigger pads crack driveways, sidewalks, and podium decks, and slurry blows out of a coupling onto glass, cars, EIFS, or landscaping. When a line blocks, you buy a pipeline set and inherit an unwinnable argument over whose mix caused it, whether slump, retarder, aggregate, or heat, because you were the last one holding the hose. The claim comes as a backcharge letter netted against invoices you've already earned. Boom truck policies get rated like crane policies, so most of these sit under the deductible and you self-insure them in full.
Three moves, in order
Step 06: Project management
Billing dates, change orders, and notices, run as standards that hold without anyone chasing them.

What concrete pumping owners ask
Customer backcharged me for driveway damage from outriggers?
A letter reaches you in June about a driveway your outriggers cracked in April, and the amount comes straight off your next check.
What does it cost?
Recurring four-figure deductions never touch the job cost record, and they never get coded to the pour that caused them, so no margin report you look at includes them.
What do I do first?
Photograph the setup before the outriggers go down and after they come up, every pour, driveway or not, filed against the ticket number.
What are concrete pumping contractors supposed to be making?
Concrete pumping runs 23% gross margin, 16% 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 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.
