CURTAIN WALL / GLAZING: THE SUBMITTAL-TO-FABRICATION CRITICAL PATH
Nothing can be fabricated until shop drawings are approved and field measurements confirmed. Custom curtain wall runs 16 to 24 weeks from approved shop drawings to first delivery; storefront fabrication runs 10 to 14 weeks; specialty glass 10 to 16 weeks from order release.

WHERE THE MONEY GOES.
Nothing can be fabricated until shop drawings are approved and field measurements confirmed. Custom curtain wall runs 16 to 24 weeks from approved shop drawings to first delivery; storefront fabrication runs 10 to 14 weeks; specialty glass 10 to 16 weeks from order release. Every week a submittal sits in review is a week of schedule slip that the glazing sub absorbs while other trades keep billing.
THE SAME PROBLEM, WRITTEN UP.
A 'Revise and Resubmit' response is expensive. It adds weeks to your schedule, delays fabrication, and creates schedule pressure that leads to shortcuts.

Glazing isn't like drywall. You can't accelerate it by adding more crews once glass units are in fabrication.

THE NUMBER TO MEASURE IT AGAINST.
Curtain Wall / Glazing contractors run about % net profit at $1M to $5M, rising to roughly 11% at $5M to $10M. The CFOS target at $1M to $5M is11.5%, set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher. A problem like this one lives in the distance between those two figures rather than in a loss on any single job.
Gross margin over the same bands runs % to 28%, against a CFOS target of 11.5%.
THE SYSTEM THAT FIXES THIS.
Billing, documentation and collections, which is where the days hide.
