Miscommunication during the design phase can lead to technical misalignments that ripple through procurement, fabrication, and installation. In this blog, we examine a project where design assumptions and communication gaps caused costly rework.
The Incident: Misaligned Mullion Placement in Retail Façade
A US distributor was contracted to supply curtain wall glass for a flagship retail store in an urban center. The design team had specified the mullion layout in early drafts, but a late-stage architectural change shifted key alignment points. The updated drawings were sent to the architect—but not to the distributor.
The distributor proceeded with fabrication based on outdated details. Once the panels arrived on-site, installers realized the vertical alignment would not match the revised façade anchoring system.
Failure Points Identified
No centralized drawing update confirmation between architect and distributor
Final approved drawings were emailed to the general contractor but never cascaded down
No drawing version control was used between design, sales, and production teams
The Consequences
Over 40 large-format glass panels had to be re-cut. Lead times were extended by four weeks, and premium expedited freight was required to maintain the store opening timeline.
Corrective Actions Taken
Drawing Change Protocol Formalized
No fabrication begins without documented sign-off of the latest design files across all stakeholders.
Version Control Platform Adopted
Cloud-based design management now ensures real-time access and update alerts for every project drawing.
Mandatory Design Coordination Call
A kickoff call between contractor, architect, and distributor is now required for custom architectural jobs.
Lessons for Glass Distributors
Fabrication without verified drawings is an invitation to rework
Design communication is a shared responsibility—don’t assume alignment
