Your plan price is locked and lumber reprices every week
You priced the plan off a March quote and you're still setting walls on that same plan in October at March money.
Framing is the trade whose material half is a traded commodity bought load by load across dozens of repeat starts on one locked price. Trades that buy fixtures or gear order once per job at a quoted price and take the hit once. You take the same hit twenty times on the same plan number and the contract never reopens.
The size of it
A 10 percent run across lumber and OSB in one season eats 5 to 6 points of contract value on a job bid at a 15 to 20 percent gross margin. By the twentieth house on that plan you're building at a loss and still booking revenue.
The lumber package is 50 to 60 percent of a material-and-labor framing number, and it moves every week while your plan price sits still for a season of starts. NAHB has framing lumber at $558.19 per MBF, up 2.1 percent in a month, with a 35.9 percent duty stack on Canadian softwood on top of that and open volatility from tariffs and supply bottlenecks. OSB sheathing runs its own cycle and swings harder than dimensional. The production builder's model is one fixed price per plan good for a year of starts, so escalation language gets refused as a matter of policy before anyone reads it. Every start after the first one moves against you, and you hold all of it.

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

What framing owners ask
How do framers handle lumber price increases on fixed plan pricing?
You priced the plan off a March quote and you're still setting walls on that same plan in October at March money.
What does it cost?
A 10 percent run across lumber and OSB in one season eats 5 to 6 points of contract value on a job bid at a 15 to 20 percent gross margin. By the twentieth house on that plan you're building at a loss and still booking revenue.
What do I do first?
Break lumber, OSB, and fasteners out of the plan price in your estimate so the material half of the number can be tracked on its own.
What are framing contractors supposed to be making?
Framing runs 18% gross margin, 13% overhead and 5% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits 2 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.
