Z--RM 7-01, Repairs to Submarine Propeller Profiler Building 1029, Philadelphia Navy Yard (PNY), Philadelphia, PA.

The purpose of this project is to repair the existing electrical system in Building 1029 at the Naval Foundry and Propeller Center (NFPC) to provide a safe, environmentally controlled work area. Building 1029 is a 90,180 SF high bay industrial facility that was constructed in 1979. It is the inside machine shop for the Naval Foundry and Propeller Center and is responsible for the milling of all sizes of propellers for surface ships and submarines. Building 1029 equipment includes propeller profilers, PROMS (Propeller Robotic Optical Milling System), and various others milling machines, lathes, saws and grinders in support of the propeller manufacturing operations. These large profilers can mill propellers up to 24 feet in diameter and require a controlled environment to maintain milling tolerances. This project will repair the existing HVAC system and the installation of air conditioning in the high nay of Building 1029. These repairs, replacements and equipment additions will improve the workplace environment inside the machine shop of Building 1029 at the NFPC with improved heating and ventilation to support ship and submarine propeller manufacturing and shall meet the operational requirements of manufacturing propellers within the specified temperature range to maintain its’ critical tolerance level for the future profilers to be located in the central bays of Building 1029. This project will also replace the low voltage 480V aluminum cables with copper wiring between the substation and various power panels. In addition, all aluminum conductors from distribution panel boards to subpanels and associated transformers will be removed and replaced with copper conductors. New circuits will also be provided for the new equipment, and smoke detectors, with required fire alarm system interfacing in compliance with National Fire Protection Association (NFPA) requirements. This project scope will also include the removal of abandoned steam lines and asbestos-containing and other hazardous materials.
