SCOPE OF WORK (SOW)

Sagamore Hill National Historic Park – Visitor Center Building Demolition

I. Background and Purpose The visitor center at Sagamore Hill National Historic Site is a single story, structurally sound, wood framed structure. The visitor center was damaged by an electrical fire in January 2019. The building remains weather tight. Most of the fire damage is confined to one end of the building where the restrooms and mechanical room are located. The remainder of the building sustained heavy smoke damage. The government requires that the building be demolished and removed from the property. Existing utilities such as telephone, CCTV, fiber optic, waterline, parking lot lighting, underground fuel oil storage tank, and sanitary sewer will need to be terminated or have operation restored as described herein.

II. Scope and Objectives In general, the scope of this project is to secure the site for demolition, remove all asbestos containing cement board in the restrooms and mechanical spaces complete, remove florescent lights, demolish and remove the entire building from the site. A fiber optic cable, telephone line, electrical service for the parking lot lights, and cables for security cameras located in the parking lot will need to be preserved during demolition and in some cases, relocated in order to maintain service (see drawings sheet E-1 and E-2). Due to archeological sensitivity of the immediate area around the visitor center, the exterior foundation walls will remain in place with the exception that the first two rows of block will be removed. The demolition contractor shall backfill the crawl space with compacted clean soil/topsoil to match surrounding grade and for drainage before performing lawn operations.

III. Supporting Information The following attachments are included for this project:

1. Asbestos Inspection (38 pages)

2. Asbestos Supplemental Inspection Report (13 pages)

3. Lead Paint Inspection (9 pages)

4. Asbestos Abatement Air Monitoring (22 pages)

All equipment mobilized on-site shall be free of excess soil and/or plant material collected off-site which could potentially contain exotic/invasive species. All equipment leaving the site, not contained in a dump truck or dumpster, shall be free of asbestos containing material.

Labor practices, tools and equipment shall meet or exceed OSHA requirements. In case of conflicts between Federal, State, and local safety and health requirements, the most stringent shall apply.
