Because PMs Don’t Want Apologies—They Want Control
Spec deviations aren’t always avoidable. But when they show up late—or undocumented—they can push PMs from field management into full-blown damage control. It’s not just a deviation—it’s a breakdown in trust.
Where Spec Deviations Sneak In
Alternate fire-rated glass shipped without UL label.
Finish substitutions not matching adjacent systems.
Insulating value altered—without stamped approval trail.
What PMs Say (While Writing Their Final Job Notes)
“We had to chase them for every deviation detail.”
“That deviation nearly failed our final inspection.”
“We never got clean documentation—and had to explain it to the architect ourselves.”
Why It’s a Repeat Business Killer
It exposes PMs to scrutiny from clients and design teams.
It signals poor internal process and documentation.
It leaves a negative final impression—right before the next bid list is created.
Dealing with Deviations Like a Pro
Pre-package full deviation request: product spec, lead time delta, impact summary.
Always get written approval—not just verbal signoff.
Include a running deviation tracker in your project docs.
Conclusion
Spec compliance isn’t just about materials—it’s about risk. And vendors who can’t control spec changes lose more than the CO. They lose the PM’s trust.
