MILCON P-547 Power and Propulsion Facility

The MILCON P-547 Power and Propulsion Facility (P-547) objective is to provide a single point venue for U.S. Navy Research, Development, Test, and Evaluation (RDT&E) program managers to conduct full scale testing for vessel propulsion systems at the Philadelphia Navy Yard (PNY). The objective is achieved by repurposing areas of the existing Building 633 high bays, constructing a high bay building extension (HBBE) addition to Building 633, and constructing a waterfront relieving platform along the 16^th Street wharf for transferring propulsion test equipment into the facility. P-547 will provide the necessary infrastructure improvements to allow the transportation of the propulsion equipment from the Sea Shuttle barge in the Reserve Basin to the new High Bay Building Extension. Lessons learned from the project include the importance of incorporating utility expansion and phasing into the design of a new wharf structure at an existing facility, specifying specific testing and coating procedures for test piles that will be used as production piles, and providing the contractor additional guidance on dimensions for support of excavation for mass concrete structures.
