I Hold the Warranty: JE Dunn's Callie Johns on the Quality Cop Problem

Sep 14, 2026

Callie Johns went to Northern Arizona University undeclared until her uncle staged an intervention over dinner. Ten years later she is a Quality Manager at JE Dunn, running the quality program on a hyperscale data center in Ohio after stints in Phoenix, Oregon, and Austin. She started as a project engineer, hated pushing change orders, fell in love with the exterior enclosure mock-up, and asked to move into quality right as COVID hit. When her boss quit three months into her first quality role, her dad told her to throw her hat in the ring. She did.

Carolina and Tim sat down with Callie to find out what the quality manager on your job site is actually thinking when she walks up to your installer, and what she wants from the manufacturers whose products she inspects.

The short answer: she is not a quality cop, she does more homework than your rep, and she holds the warranty.

We get into the modular unit vendor who sealed a penetration on one side and could not see why both mattered, the "just put a bead of butyl" answer that fails in two years, the client-mandated quality collaborative where competing GCs share lessons learned, and why substitutions are the best reset button a project gets. Then Callie answers our closing question with the thing she thinks the industry should be talking about: the learning opportunities we walk past every day because nobody takes the ten minutes.

In this episode:

• The "rep" quality people get on site, and why Callie refuses to be the quality cop
• Doing the homework: plans, details, shop drawings, install instructions, pre-install minutes, all of it, before the contentious conversation
• "I completely disagree with how you installed this wall flashing, but let's work through it"
• Owning the joint when more of the building shows up as modular units
• "I don't know right now, but I will respond tomorrow"
• The quality collaborative: competing GCs on the same hyperscale program sharing what went wrong
• Emerging leaders, imposter syndrome, and why she asked ACQ to put people like her on stage
• What the field un-teaches you after a CM degree and a master's earned while working full time
• Substitutions as a reset: first work in place, manufacturer on site, everyone aligned before the rip-out
• "Give me the ten minutes and I will tell you how to install it" and why the word warranty opens doors
• Why it is scary to walk a site with QC, from both sides of the hard hat
• Perpetual pass-down and the shadowing conversation nobody is having
