Nobody builds your elevator until layouts come back
Six weeks of architect and GC review sit on top of your lead time, not inside it, and the factory doesn't cut a rail until the stamped layout comes back.
Most subs measure lead time from the day they place the order. Yours starts the day an architect signs, which means the party holding your schedule has no money at risk in it. Two approvals, held by two different parties, sit in front of a single manufacturing clock that can't start early.
The size of it
Six weeks of review plus a two-week out-of-tolerance hoistway fix moves the whole schedule two months to the right while you carry the deposit and burn estimated hours on a job with no billing activity.
Release for manufacture is gated on approved layout drawings: pit depth, overhead, hoistway plumb, entrance sizes, and machine room or MRL clearances. Until that approval comes back, the 20 to 40 week clock hasn't started, so every week the drawing sits on somebody's desk is a week added to the back end of the job. Then comes a second gate almost no other trade has, the field hoistway survey before mobilization. If the concrete or masonry is out of plumb or the pit runs short, you either eat rail bracket and entrance remediation or you stand down while another trade fixes structure. Both gates belong to other people, and both get blamed on the elevator sub.
Three moves, in order
Step 06: Project management
Billing dates, change orders, and notices, run as standards that hold without anyone chasing them.

What elevator owners ask
Elevator layout drawing approval took six weeks who pays for the delay?

What does it cost?

What do I do first?
Date-stamp submittal out, approval in, and release to factory on every job, and age open submittals in your weekly meeting the same way you age AR.
What are elevator contractors supposed to be making?
Elevator runs 27% gross margin, 18% overhead and 9% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits 2 points above it. The CFOS target is 12%.
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.
Sulphur Prairie Operations LLC maintains the benchmark reference behind these figures. Every edition is reconciled against the newest CFMA survey release before it publishes here. Where a figure changes between editions, the older edition keeps its year in the title so a citation to it stays correct.
