Witchita VA Hospital
Wichita VA strengthening required engineering clarification of concealed topping layers and coordinated preparation before FRP installation.
Delta Structural Technology completed strengthening work for the Wichita VA hospital’s additional-elevator project. During the work, concealed conditions at a fourth-floor FRP location required clarification from the engineer. Delta coordinated through the contractor and returned to complete installation after the required area was prepared. The case illustrates the connection between field discovery, engineering response and composite installation.

Project challenge
After removal of brick and lightweight concrete, the contractor observed a condition that appeared to be a joint between a column and the existing deck. The shop detail had shown the elements connected. Understanding the actual assembly was necessary before reinforcing the location. Another area was not yet accessible, requiring the installation sequence to account for preparation by the general contractor.
Project approach
The engineer’s site review determined that the apparent joint was associated with an additional leveling or topping slab above the existing structural floor system. The response directed investigation of the topping depth while avoiding the beams and pan joists, followed by removal of topping at the beam location and reinforcement as required. Delta’s operations correspondence confirms that installation proceeded as directed after the crew remobilized.
Delivery and coordination
The contractor submitted RFIs for the conditions encountered, and the engineer of record issued responses. Delta shared those responses with the composite supplier when follow-up questions arose. The project’s operations team served as the point of coordination for the field work, connecting access readiness and the engineer’s clarification with the crew’s return to the site.
Project significance
The Wichita VA project demonstrates why concealed layers should be distinguished from the structural substrate before FRP is installed. The field condition changed the understanding of the assembly and required an engineering response. The case provides a practical example of managing that discovery through the project’s RFI process and coordinating the installation around the resulting preparation work.
