Fort Sam Houston 915 916
Concrete restoration and FRP reinforcement addressed shear and flexure in exterior stair beams at Fort Sam Houston Barracks 915 and 916.
Delta Structural Technology completed exterior stair beam repairs at Fort Sam Houston AIT Barracks 915 and 916. The strengthening scope addressed both shear and flexure, pairing concrete restoration with FRP reinforcement. Delta worked with the project’s design team and a specialty FRP engineer to define the reinforcing requirements and the division of responsibility for the underlying concrete repairs.

Project challenge
Existing conditions required careful clarification before the FRP design could be completed. The engineer asked about reinforcing steel, concrete strength, beam depth and the required strengthening modes. Available photographs helped frame the discussion, but the design team also sought existing drawings. These questions were important because an exterior stair beam repair has to reflect the member actually in place.
Project approach
The proposed package covered twelve beams requiring shear and flexural upgrades. Delta agreed to handle the concrete repairs while Baykal Consulting prepared the FRP design. The project team discussed repair drawings from the engineer of record as the basis for the concrete work. This separated the specialized composite calculations from the restoration scope while keeping both parts of the beam treatment coordinated.
Delivery and coordination
Delta’s exchange with ECC and the specialty engineer established the information needed to proceed and identified assumptions requiring confirmation. Concrete dimensions and reinforcement were not treated as interchangeable with another barracks project. The design discussion also recognized the importance of preparing repaired beams to receive FRP, connecting the condition of the substrate with the subsequent reinforcing installation.
Project significance
Barracks 915 and 916 illustrate a combined repair strategy for existing military facilities. Concrete restoration and composite reinforcement addressed complementary needs, while a clear engineering interface helped define the work. The case demonstrates the value of resolving existing-member information before finalizing an FRP package, particularly when photographs and incomplete drawings are the starting point.
