Chatham County EOC


Current regulations mandate that an Emergency Operation Center (EOC) adhere to storm shelter requirements, as outlined in ICC-500 and FEMA P-361 guidelines. Here, the architect required a custom solution to safeguard incoming utilities penetrating the hardened shell.


RPH worked closely with the design and construction team to engineer a highly customized solution for installing a Custom CYCLONE® Steel Housing (CSH). This involved coordination with the roofing and technology contractors to ensure an optimal RPH Exit Seal™ and gasket hole configuration, meeting precise specifications. The unit was designed to provide safe future pathways. Notably, the Custom CSH adhered to the same rigorous standards as our standard CYCLONE® products.
