Fort Gordon Bldg 21720 Progressive Collapse
Fort Gordon CFRP work included engineering coordination for proposed penetrations through reinforcement installed for progressive-collapse resistance.
Delta Structural Technology completed progressive-collapse CFRP work at Fort Gordon Building 21720. A later field coordination issue involved proposed two-inch penetrations through installed reinforcement. Delta referred the condition to the security engineering team and sought an official response for the construction team and Corps of Engineers. The exchange illustrates the need to manage changes to a reinforcing system after installation.

Project challenge
A penetration through FRP can interrupt the reinforcement placed to satisfy a specific structural requirement. The engineer needed to know whether the proposed holes passed through the floor slab or perimeter beam, where they occurred in plan and their vertical position where applicable. The first marked drawing did not resolve those questions, so field clarification was essential before a response could be finalized.
Project approach
Delta gathered information from the general contractor, prepared a sketch and transmitted the proposed hole locations to Applied Research Associates. The engineering response provided instructions for additional CFRP intended to replace the loss of strength at the penetrations. Delta then coordinated the resulting scope with the contractor. The work remained tied to the original progressive-collapse design and the engineer’s assessment of the specific interruption.
Delivery and coordination
The correspondence connected Delta’s field team, Windamir and ARA’s security engineering group. It established a route for reviewing the change through the project’s engineering and owner channels. Rather than treating the holes as a routine trade opening, the team addressed how they interacted with the installed composite system and what reinforcing measures the engineer required at those locations.
Project significance
The Fort Gordon case highlights the importance of protecting the continuity of an installed structural upgrade. Composite reinforcement continues to require coordination as other trades complete their work. A process for penetrations helps keep field changes aligned with the design intent, particularly in a military project where the reinforcement serves a progressive-collapse function.
