Gill Elementary Beam Reinforcement
Anchored carbon fiber beam repair at Gill Elementary combining U-shaped shear reinforcement and underside flexural strengthening.
Delta Structural Technology completed carbon fiber strengthening at Gill Elementary to address cut reinforcing bars. The scope used a Tyfo composite design provided through SIG and combined shear strengthening with additional flexural reinforcement. Carbon fiber anchorage formed part of the installation detail, connecting the repair geometry with the engineered requirements for the affected concrete beams.

Project challenge
The triggering condition was cut reinforcement in existing beams. The repair therefore needed to provide more than one strengthening function. A three-sided U-shaped treatment addressed shear, while reinforcement on the beam underside addressed flexure. Access and infill were separate project responsibilities, making coordination essential before the reinforcement surfaces could be prepared.
Project approach
Delta’s scope included procurement after submittal approval, protection of existing finishes and layout according to the composite shop drawings. The receiving concrete was to be ground to the manufacturer’s preparation requirements. Carbon fiber anchors followed the engineer’s drawings, and the reinforcement was applied to the approved layout. The three-sided and underside treatments were distinct components of the same beam repair strategy.
Delivery and coordination
The project assigned access and infill work to others. Delta’s installation sequence therefore depended on those areas being available and prepared for the reinforcement work. Approval of shop drawings connected material procurement to the final design, while finish protection addressed the surroundings of the work area. The coordination requirements linked the repair detail with the practical conditions needed for installation.
Project significance
Gill Elementary illustrates a targeted strengthening response to damaged embedded reinforcement. The defining technical feature is the combination of anchored carbon fiber, U-shaped shear reinforcement and underside flexural treatment. The case emphasizes how a repair scope can address multiple beam demands while maintaining a clear division between composite installation and related access or infill work.
