Design miscommunication between architects, fabricators, and distributors is a major risk factor in custom glass projects. This blog dissects one such breakdown and how better coordination could have saved weeks of delay.
The Incident: Clerestory Glass Alignment Error in a Museum Build
A distributor provided oversized IGUs for a museum clerestory design. The architectural drawings had been updated with a new transom spacing dimension, but the revised drawing set was never received by the distributor’s fabrication team.
The glass arrived with mullion misalignments, which could not be corrected on-site due to rigid frame specs. Fabrication had to restart entirely.
Where the Miscommunication Occurred
The architect issued revised drawings, but the general contractor failed to forward them
Internal order approvals were based on an outdated drawing revision
No drawing sign-off process was enforced at the distributor level
Consequences
Six-week delivery delay
Client’s project budget overrun by $130,000
The distributor lost its “preferred vendor” designation with the architect’s firm
Preventative Actions
Drawing Receipt and Revision Logs Enforced
All design files must now be uploaded into a shared platform with revision stamps and digital receipt confirmations.
Design Freeze Review Meetings Created
Before fabrication, a final freeze review must be conducted involving sales, engineering, and logistics.
Dedicated Design Liaison Role Added
A new role ensures continuous communication between design teams, architects, and internal stakeholders.
Strategic Lesson
If you don’t control the flow of design data, it will control the outcome of your project. Every drawing update should be tracked, confirmed, and archived—because misalignment costs more than just time.
