You Bill Hours. The Steel Wears by the Yard.
Two four-hour pours bill the same, and one of them wore out a whole pipeline. The invoice meters time; the machine meters yardage.
A labor trade's four hours costs four hours of labor, every time. Your four hours costs whatever the mix, the yardage, and the slick line took out of the steel, so a 120-yard high-rise pour on 300 feet of line with a stiff mix destroys many times what a 40-yard driveway slab does. Both of those invoice at roughly the same four hours, and the money leaves at the parts counter weeks later.
The size of it
Gross margin per pour swings 20 to 30 points with nothing on the ticket to explain it. The whole cost sits in one undifferentiated repairs and maintenance line that ties to no truck and no pour.
Two four-hour tickets can carry completely different steel costs, because the invoice meters pump hours and the machine meters cubic yards and feet of line. Revenue is hourly pump time plus a small per-yard adder, usually three to four and a half dollars a yard on published rate cards. Cost is the S-tube, wear plate, cutting ring, reducers, elbows, end hose, and twin-wall boom pipe worn away by yardage and system length, and manufacturers write wear parts out of the warranty on purpose. Until yards pumped and feet of line get written on the same ticket as the hours, nothing in your books tells you the difference is there.

What concrete pumping owners ask
How to track concrete pump wear parts cost per pour?
Two four-hour pours bill the same, and one of them wore out a whole pipeline. The invoice meters time; the machine meters yardage.
What does it cost?
Gross margin per pour swings 20 to 30 points with nothing on the ticket to explain it. The whole cost sits in one undifferentiated repairs and maintenance line that ties to no truck and no pour.
What do I do first?
Add three fields to the pour ticket and make the operator complete them before he leaves the site: yards pumped, feet of system line, and mix or slump.
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 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.

Where a figure changes between editions, the older edition keeps its year in the title so a citation to it stays correct.
