Haul Miles Are Your Commodity Price, and They Moved
The rock price held all year. The trucking on it didn't, and then the spoil site quit taking dirt halfway through the export.
There's no drawing revision behind a haul route change, so there's nothing to attach a change order to. The design held still and the truck didn't. Fuel adjustment clauses are standard on DOT work and almost never appear on a private site package, which leaves the sub holding the entire move between bid day and buyout.
The size of it
On a 40,000 CY export, adding 15 miles each way is a six-figure swing on one job. Nothing on the plans changed, so the whole thing settles into your cost of work.
Your commodity is haul, and haul is priced per loaded mile against a radius you fixed the day you bid. Freight runs 40 to 60 percent of a delivered aggregate invoice. Add a fuel surcharge of 4 to 8 percent that floats with diesel and a $5 to $15 per ton logistics charge on top, and the stone itself is the minority of the ticket. Import select fill and export spoil both get priced off that assumed radius. When the borrow pit runs short, the spoil site fills up, or the county restricts a haul route mid-job, a five-mile round trip becomes twenty and your largest cost line roughly doubles.
Three moves, in order
Step 02: Equipment cost basis
A true internal rate per machine covering ownership, maintenance, fuel, and transport, charged to the projects that used it.

What sitework owners ask
How to price haul when the spoil site closes mid job?
The rock price held all year. The trucking on it didn't, and then the spoil site quit taking dirt halfway through the export.
What does it cost?
On a 40,000 CY export, adding 15 miles each way is a six-figure swing on one job. Nothing on the plans changed, so the whole thing settles into your cost of work.
What do I do first?
Write the borrow pit and the spoil site into the bid, with the round-trip mileage and tipping rate you priced, so the assumption lives on the contract and not in your head.
What are sitework contractors supposed to be making?
Sitework runs 18% gross margin, 15% overhead and 3% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits 4 points below 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.
