These are construction documents for the National Park Service Historic Preservation Training Center detailing a masonry barrier wall project at the southeast corner of 6th and Market Street in Independence National Historical Park, Philadelphia, Pennsylvania. The documents are dated June 10, 2026, and include design drawings, general notes, abbreviations, historic treatment terminology, site plans, and wall elevations and sections.

The project requires construction of a masonry barrier wall with associated site work including temporary construction perimeter fencing, protection of existing site elements, and coordination with landscape features and underground utilities. The general contractor must comply with ICC Family of Codes and NFPA 70 electrical code as adopted by the National Park Service per Policy Memorandum 23-01. All work must be field-verified prior to bidding, with special attention to historic preservation standards including gentle removal and salvage of designated items, protection of existing features throughout construction, and adherence to specific historic treatment protocols such as consolidation, replication, restoration, and reversible construction methods. The contractor is responsible for site layout coordination with the Contracting Officer's Representative, protection of all existing conditions noted in the documents, and repair or replacement of any damaged items at no additional cost to the government.
