About this file
This Statement of Work (SOW) details repair requirements for the Marioff high-pressure water mist system located at the Yosemite Valley Museum/District Ranger Office in Yosemite National Park. The project involves replacing critical system components, including the GPU6D/B nitrogen-driven high-pressure fire pump, TJ4362T nitrogen-driven jockey pump, and all high-pressure rubber flex lines on the nitrogen reserve bank and pump system. Additionally, the contractor must conduct hydro testing and refilling of 24 nitrogen bottles, recertify and fill the tanks per industry standards, and perform a complete annual inspection with a detailed California NFPA inspection report.
The project is specific to a historic 1924 museum building housing valuable collections and administrative offices, emphasizing the importance of maintaining a fully operational fire suppression system. The contractor is required to supply all necessary materials and equipment, perform pressure tests to ensure functionality, and adhere to all local, state, and federal safety regulations. Notably, there are hauling restrictions in the area, with vehicles over 45 feet prohibited and 1-way controlled traffic implemented 20 miles east of Mariposa due to ongoing rockslide repairs, which may impact logistics and transportation for the project.
