Coordination between glass distributors and contractors is critical, especially on tight construction schedules where staging, delivery, and install sequences are interdependent. When coordination breaks down, delays, damage, and budget overruns often follow.
The Case: Delivery to Unprepared Façade Zone
A distributor delivered curtainwall panels to a job site as per the schedule, but the contractor hadn’t completed steel framing on the upper floors. With no place to install the panels or secure them on-site, the glass sat exposed for several days. A storm damaged a portion of the shipment, and the rest had to be transported back to storage.
Breakdown Analysis
No coordination walkthrough was conducted prior to delivery.
The contractor never confirmed install readiness in writing.
Distributor relied on general assumptions based on the Gantt chart instead of verifying site conditions.
Impact
Lost over $40,000 in material damage and labor standby.
The GC withheld final payment and issued a delay claim.
The distributor’s reliability score dropped in the contractor’s vendor evaluation system.
Resolution Strategy
Establish pre-delivery coordination meetings with mandatory site readiness checklists.
Require photographic confirmation of staging areas and access paths.
Assign a project liaison to monitor inter-trade dependencies and coordinate with site supers.
Contractor coordination is not passive—it’s a project management function. Distributors who own that interface prevent issues before they escalate.
