The nine and a half foot error the agents caught themselves
On the Midtown Phoenix tower, review agents caught a bay error and a wrong setback that would have cost about $250,000 to fix had either reached a permit set.
For the architecture work on the Midtown Phoenix tower, we built an agentic system. Separate agents handled shell, structure, MEP, envelope and quality review, and together they drove a large Revit model holding more than twelve thousand elements.
Deep in that model, the review agents found a nine-and-a-half-foot error in one structural bay, along with a wrong setback. Had either one reached a permit set, fixing the pair would have run about two hundred fifty thousand dollars. Nobody told the agents where to look. They found it since the review pass was designed to doubt the model, never to take it on trust. It is the same discipline as the blind pass rule we now apply to every takeoff.
A bay a few feet off looks like nothing on a drawing, until a foundation is poured around it. The whole schedule and budget of the project rode on catching that kind of detail before the concrete, not after.
