1. BACKGROUND

The Declaration House, also known as the Graff House, is the site where Thomas Jefferson drafted the Declaration of Independence in June 1776. Located at 7th and Market Streets in Philadelphia, the house was owned by Jacob Graff, who rented a second-floor room to Jefferson during the Second Continental Congress. Jefferson composed the document over 17 days before presenting it to the drafting committee. The original Graff House was demolished in 1883. In the 1950s, the National Park Service acquired the site, and a reconstructed version of the Declaration (Graff) House with modern Annex was completed in 1975 as part of the U.S. Bicentennial commemoration. The reconstruction was based on historic descriptions, drawings, and archaeological evidence. The building is part of Independence National Historical Park and is receiving preservation treatment in preparation for the 250th anniversary of American independence.

2. SCOPE OF WORK

A. OVERVIEW

Independently, and not as an agent of the Government, the Contractor shall provide all labor, materials, equipment, and travel necessary to design, erect, assemble, and install compliant scaffolding at the Declaration (Graff) House at Independence National Historical Park in Philadelphia, PA. The scaffold shall be erected to provide full access to the north, east, and south exterior (brick) masonry walls of the reconstructed Graff House and shall remain in place for a period of ninety (90) calendar days. The system shall be designed to support multiple workers, tools, and materials across several working levels, with integrated stair access located within the confines of the perimeter safety rail. The Contractor shall verify all site dimensions prior to erection to ensure the scaffold reaches all required work areas, and all scaffold bases shall be properly footed to distribute loads.

The scaffold must be configured to prevent unauthorized access using secured access points and ground-level barriers. A Pennsylvania licensed Professional Engineer shall seal the scaffold design and structural calculations, and the Contractor shall obtain all required permits and, if applicable, submit the design to the City of Philadelphia Department of Licenses and Inspections for engineering review and approval, in accordance with Section C, Permitting and Coordination.

Scaffolding shall be provided on three elevations of the four and one-half story brick masonry Declaration (Graff) House, which has an approximate building footprint of 16’- 6” by 51’-2” at ground level. Exact building dimensions to be verified by the Contractor in the field.

The Declaration House (Graff House) is located at 7th and Market Streets within a heavily trafficked pedestrian zone of Independence National Historical Park. Where scaffolding encroaches on public sidewalks, the Contractor shall design, permit, and install a covered pedestrian passageway with lighting consistent with City of Philadelphia Department of Licenses and Inspections requirements. No anchoring to the historic structure or adjacent site features shall occur without prior written approval from the National Park Service and the Philadelphia Historical Commission. The Contractor shall coordinate all deliveries, staging, and sidewalk closures with NPS and applicable municipal agencies, while ensuring protection of trees, hardscape, and historic features, and minimizing disruption to visitor access and circulation. The Contractor shall maintain the scaffolding in a safe and serviceable condition for the duration of its use, including securing the system during severe weather and promptly correcting any damage or instability at no additional cost to the Government. Upon written notification by the Government, the Contractor shall safely dismantle the scaffold and fully restore all impacted areas to preconstruction conditions.

B. SCAFFOLD LOADING REQUIREMENTS

1. The Contractor shall furnish and install a fully engineered, OSHA-compliant free-standing scaffolding system rated for heavy-duty loading (minimum 75 pounds per square foot (psf) across all working platforms. The scaffolding shall be designed to safely accommodate the concurrent use of up to twelve (12) workers performing masonry restoration work, inclusive of all required tools, equipment, and construction materials, distributed across multiple working levels. Anchoring to the historic brick structure at the mortar joints will require prior written approval from the National Park Service and the Philadelphia Historical Commission.

2. Each scaffold platform shall:

a. Be rated to support a minimum of 2,100 pounds per typical 7 ft x 4 ft bay.

b. Be configured to allow simultaneous operation by two (2) masons with materials per bay, or equivalent distributed loading.

c. Be fully decked and equipped with all required fall protection, including toe boards, guardrails, and mid-rails, per OSHA 29 CFR 1926 Subpart L.

3. Rooftop bearing of scaffolding on the adjoining annex structure at west side of

Reconstructed House is not authorized.

4. The scaffold system shall be designed to account for the cumulative vertical loading from multiple occupied levels and shall include proper bracing, anchorage, and tie-ins at masonry joints (if approved by CO in writing) per engineering best practices and local building code.

5. The Contractor shall submit scaffold design drawings and structural loading calculations sealed by a Pennsylvania-licensed Professional Engineer. If required by the City of Philadelphia Department of Licenses and Inspections (L&I), the scaffold design shall also be submitted to the city for engineering review and approval.

3. Delays resulting from the Contractor’s failure to prepare, complete, or submit permit applications and required documentation in a timely and complete manner shall be the sole responsibility of the Contractor and shall not entitle the Contractor to a cost or time extension. However, delays attributable solely to third-party review or approval agencies—despite timely and complete submittals by the Contractor—may be considered for a non-compensable time extension at the discretion of the Contracting Officer.

4. Contractor shall submit scaffolding design for review and approval by a Pennsylvania-licensed Professional Engineer. If required by the City of Philadelphia Department of Licenses & Inspections (L&I), the design shall also be submitted for review and approval by city engineering staff.

5. Even in the absence of excavation, the Contractor shall contact Pennsylvania One Call to request a utility locate for all areas where scaffolding will be placed. The Contractor shall submit utility locate confirmation to the Contracting Officer’s Representative (COR) prior to scaffold erection. If underground vaults, utility covers, or other subsurface structures are identified within the scaffold footprint, the Contractor shall notify the COR and submit a site plan identifying affected areas.

Scaffold placement over such features shall not proceed without review and written concurrence from a Pennsylvania-licensed Professional Engineer. The Engineer shall evaluate potential loading risks and design any required bridging, shoring, or load distribution systems to ensure the structural integrity of subsurface features. The Contractor shall implement the Engineer’s recommendations in full and submit all calculations, stamped drawings, and protection details to the COR prior to erection, at no additional cost to the Government. All protective measures shall be installed in accordance with the Engineer’s design and documented with photographic evidence prior to use.
