You bid the binder in February and buy it in September
You priced the lot in winter, the GC's schedule slid, and the tons you're buying now cost more than the tons you sold. Nobody on a private hard bid writes escalation clauses.
A framer's lumber moves too, but it moves on a market they can watch and re-buy weekly. You're buying a refinery byproduct at the plant's posted price on the morning the trucks roll, against a number you committed to seven months earlier. In 2022 Kansas DOT's PG 64-22 index ran from $496 a ton in January to $774 a ton by August, and contractors on indexed work absorbed roughly 60 percent of that surge while spot buyers with no clause absorbed roughly 85 percent.
The size of it
A 15 percent binder move on a job where mix is 55 percent of cost takes 4 to 6 points of gross margin off work already sold. On a $600,000 parking lot package that's $25,000 to $35,000 with no mechanism to recover it.
The price you sold was a February price and the tons you're buying are a September price, and on private hard-bid work there's nobody to pass the difference to. Liquid asphalt cement is 4.5 to 6 percent of the mix by weight and still the largest single cost inside the ton, because it moves with crude oil, not with the construction market. State DOT contracts carry an AC index adjustment, though it lags the real market by 30 to 90 days, and GC and private work almost never carries one at all. Every week the GC's schedule slips is another week you're holding an open position on a commodity you already sold at a fixed number.

Step 04: Estimating system
The estimate maps one to one onto the job cost codes, so variance means something the day it appears.

What paving owners ask
How do I cover asphalt price increases on a hard bid job?
You priced the lot in winter, the GC's schedule slid, and the tons you're buying now cost more than the tons you sold. Nobody on a private hard bid writes escalation clauses.
What does it cost?
A 15 percent binder move on a job where mix is 55 percent of cost takes 4 to 6 points of gross margin off work already sold. On a $600,000 parking lot package that's $25,000 to $35,000 with no mechanism to recover it.
What do I do first?
Print the bid date, the binder price you used, and a validity window on every proposal, and state which index any escalation would follow.
What are paving contractors supposed to be making?
Paving runs 20% gross margin, 14% overhead and 6% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits 1 points below it. The CFOS target is 10%.
Which part of the system fixes it?
The step is number 04, estimating system. The estimate maps one to one onto the job cost codes, so variance means something the day it appears. It comes from chapter 4 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.
