1.0 GENERAL

Project Identification: The project is located at the NATIONAL REGISTER OF HISTORIC

PLACES LISTED NIKE MISSILE LAUNCH SITE within the Golden Gate National Recreation

Area, Marin County, CA. The work of this contract shall consist of the project tasks described below for the referenced project. In this document, the project shall be referred to as “the Project.” Reference numbers of this Project:

Park/PMIS Numbers: GOGA 224601

Contracting Officer’s Representative: The Contracting Officer’s Representative (COR) is designated by the Contracting Officer (CO) and shall serve as the primary POC for all technical matters. The

COR is also responsible for the approval of submittals, progress payments, and acceptance and rejection of work. The COR for this project is Jason Hagin, Fort Mason Bldg. 201, San Francisco, CA 94123, (415) 561-4973, Jason_Hagin@nps.gov.

1.1 BACKGROUND:

Nike Missile Site SF-88L is a nationally significant Cold War era property on the National Register of Historic Places. It is the best-preserved Nike missile launcher site in the nation, and the site in the

National Park System that best represents the Cold War historic theme and context. The site presently houses a majority of Nike missiles left in the United States (all of which are inert).

The damp, marine environment of the seaside location requires an intensive program of cyclic maintenance in order to avoid serious and irreversible damage to this nationally significant resource and very popular visitor attraction. When in operation, there were 120 soldiers whose duties involved constant care of the site and its delicate equipment, and we must devote at least a fraction of this effort to its continued unimpaired preservation.

The Missile Warhead Building (FA967) is a 784 sq. ft. concrete block building 20’-0” x 40’-0” with metal rolling doors at either end constructed in 1959. Two existing exterior wood entry doors need to be replaced with pre-hung fiberglass doors to fit a 3’-0” x 7’-5” rough opening (2’-8” x 7’-0” doors), reusing existing latch hardware. The building’s rolling service doors need to be refurbished if feasible or replaced with new doors that match the existing/historic.

The Exclusion Area Fence needs to be repaired with an allowance for up to 5 new replacement 45º arms, and 400 linear feet of three-strand barbed wire needing to be re-hung. Also, a tensioning wire needs repair/re-alignment or replacement if required.

The Magazine A Elevator work consists of replacement of eighteen (18) steel chase covers with matching new ones.

1.2 SCOPE:

A. Contractor shall furnish all necessary supervision, labor, tools, parts, material, equipment, appurtenances and transportation for the “Repair and Correct Deferred Maintenance at Historic Nike

Site Project.” The Project is located in Fort Barry in the Marin Headlands near Rodeo Beach in The

Golden Gate National Recreation Area (GGNRA), Sausalito, Marin County, California as specified herein.

B. Contract documents provided by the Contracting Officer will include archive drawings, site photographs and initial bid site walk through. This information will be made available from Jason

Hagin, Historical Architect, Contracting Officer’s Representative (COR), Building 101 Fort Mason,

(415) 561-4973, E-mail: Jason_Hagin@nps.gov
