Cajun Industries was selected to provide full Engineering, Procurement, Fabrication, and Construction (EPC) services for the delivery of two multi-story, blast-resistant precast concrete Gas-Insulated Switchgear (GIS) buildings, each measuring approximately 200 feet by 45 feet. Designed to withstand a 1.5 psi blast loading, these hardened structures were engineered to house critical high-voltage GIS equipment and associated electrical infrastructure. The project scope also included the design and construction of two precast concrete control buildings of similar construction, providing integrated operational and control capabilities. This turnkey EPC solution incorporated structural, electrical, HVAC, fire protection, grounding, and utility systems, resulting in a highly resilient and secure facility that enhances grid reliability, operational continuity, and personnel safety within the client’s power distribution network.
