Field service teams often represent the final touchpoint in the glass supply chain—but also the highest risk. Mistakes made during site handling or installation are typically blamed on the product, even when the root cause lies in process. This blog covers a real audit breakdown involving preventable field service errors.
The Incident: Damaged Coated Glass from Improper Handling
A US distributor delivered oversized low-E units for a government building project. The product passed QA and arrived undamaged, but field techs used suction cups that were incompatible with the coating, leaving abrasions and micro-scratches across the surface.
The damage wasn’t immediately visible but appeared under natural lighting conditions a week after installation. The client demanded full replacement.
Failure Points Identified
Field crew was not briefed on coating sensitivity
No job-specific handling protocol was shared
QC inspections skipped post-installation due to project rush
Consequences
$145,000 in replacement and expedited shipping
Project GC initiated dispute resolution, delaying payment by three months
Internal audit triggered a full SOP review of field procedures
Remedial Steps Taken
Job-Specific Handling Protocol Required for All Deliveries
Every shipment now includes a printed handling and installation guide customized by product type.
Field Service Training Updated
All techs are trained on material-specific handling tools and flagged for re-training every six months.
Post-Installation Inspection Mandated
A field QA checklist must now be completed and submitted within 24 hours of install.
Core Insight
Field service mistakes don’t start at the site—they start at the dock. Success in the field requires proactive alignment across product knowledge, training, and job briefings.
