A ten week mill run can't absorb a late color pick
The designer is still sitting on samples, your carpet is a ten week mill run, and the certificate of occupancy date hasn't moved an inch.
A late submittal costs most trades a few days of resequencing. It costs flooring the entire mill run, because the product doesn't exist yet and can't be bought locally at any price when the color is a custom dye lot. Being the last finish means there's nothing downstream left to compress except your own crew, which is why every week the designer holds samples comes back to you as premium time.
The size of it
A four week late color approval turns into a fourteen week material date, and the CO date doesn't move to meet it. You hold that date with overtime, night shift, and doubled crews that were never in the bid, routinely 15 to 25 percent of your labor line.
Specified carpet and custom LVT are made to order, not pulled off a shelf. Broadloom and carpet tile in a specified color go onto a scheduled mill run, imported LVT ships by container, and neither clock starts until the architect approves the sample and the owner signs the finish schedule. Finish selection is the single item on a commercial job that gets deferred the longest, and flooring installs last, so an 8 to 12 week lead time and the approval delay stack into the same weeks with no float left to absorb either one. Reorder anything and you get a different dye lot, which means re-running the whole area instead of patching a corner. The schedule absorbs none of that, so your labor does.
Three moves, in order
Step 06: Project management
Billing dates, change orders, and notices, run as standards that hold without anyone chasing them.

What flooring owners ask
Late finish selections pushing my commercial carpet lead time past the CO date?

What does it cost?

What do I do first?
Build a one page lead time sheet for your top ten specified products with a hard order-by date on each line and put it on the table at the preconstruction meeting.
What are flooring contractors supposed to be making?
Flooring runs 19% gross margin, 14% 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 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.

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