About this file

This is a Statement of Work (SOW) for the installation of a masonry barrier wall at Independence National Historical Park's President's House site in Philadelphia, Pennsylvania (PMIS #351014). The project requires construction of a reinforced masonry barrier wall with associated site improvements including excavation, grading, concrete foundations, site restoration, and final cleanup. The work must be executed in June 2026 and is subject to extensive historic preservation requirements given the project's location within a nationally significant historic park.

The SOW establishes comprehensive administrative, quality control, environmental protection, and historic resource preservation requirements. Key contractual elements include: (1) preconstruction submittals due within 15 calendar days of Notice to Proceed, including Quality Control Plan, site logistics plan, Cultural Resource Protection Plan, and traffic control plan; (2) mandatory weekly progress meetings and daily construction reports; (3) compliance with Secretary of the Interior Standards for Historic Properties and National Park Service preservation guidelines; (4) protection of existing vegetation, site features, utilities, and undiscovered archaeological resources with immediate work stoppage requirements upon discovery; (5) 6-foot minimum protective fencing around tree protection zones and sensitive areas; (6) prohibition on attaching temporary structures to historic fabric; (7) submittal of shop drawings, product data, and samples with contractor certification before work commences; (8) continuous monitoring of vibration, dust, and noise impacts on historic resources; and (9) removal and replacement of nonconforming work at contractor expense. The contractor must provide a qualified superintendent and full-time Quality Control Manager onsite, maintain record documents updated weekly, and obtain COR (Contracting Officer's Representative) approval for all deviations. Final acceptance requires submission of updated record documents, warranty documentation, operations and maintenance data, and cultural resource protection reports demonstrating full compliance with preservation standards.
