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 more than $40 million worth of cultural resource objects and equipment, including 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.

RFP No. 140P8621R0013 Section J - Attachment No. 002

The Missile Assembly Building Flagpole (FA963) is operational, and consists of a custom fabricated steel base comprised of two 2”x6” steel channels welded to a 2’-0” x 2’0” ¼” thick steel base plate and including an integral weighted steel tube flagpole that can be bent to the ground by a pivot pin in the steel base. The flagpole needs to be disassembled, preserving hardware if feasible or replacing it to match existing character and technical performance, and the base structure prepared, repaired in the shop using welded patches and limited replacements, then hot-dipped galvanized and reinstalled. The flagpole requires field metal treatment to address rust, and then needs to be reinstalled in the base and erected to a vertical position, ready for operation.

The Missile Loading Rack System at Magazine A (FA969) consists of modular steel trusses with two parallel tracks about 30 inches above ground and are used to convey missiles to and from the launch assemblies. The two main components of the loading racks are a support assembly and a side truss assembly. The support assemblies stand on adjustable leg base and column assemblies, which are anchored with threaded rods, designed to accommodate uneven ground, and include support columns that are secured to the side truss with headless bent pins. The top chord of the side trusses bears on the support assemblies and are also secured with headless bent pins. Many components of the loading rack system at Magazine A are rusted, deteriorated and in need of repairs. To the extent of available funding, currently installed components need to be disassembled and removed (16 Side Truss assemblies, up to 8 Support Assemblies, and up to 16 leg base and column assemblies);

replacement support assembly, side truss assembly, leg bases and column support components supplied by the Government need to be reinstalled to comprise a re-assembled Loading Rack System in good condition that can again convey missiles to the launchers.

Installation of new epoxy dowel anchors and leveling bolts (up to 64 locations) must be included to accommodate the slope of finish grade. There is an OPTION Metal Painting & Repairs scope to prepare and paint the Magazine A Elevator doors, and their adjacent associated metal and concrete features.

The main entry Sentry Station (FA970) is a 142 sq. ft (5’-5” x 7’-5”) concrete block guardhouse building constructed in 1959. The exterior of the building, including three windows and one door needs to be painted (230 sf); the roof trims and flashings need repairs and door needs to be rodent-proofed.

The Missile Loading Rack System at Magazine B (FA971) is a similar system to the Magazine A System located at the adjacent missile magazine. It is in poor condition and in need of mothball treatment. Many components of the loading rack system at Magazine B are rusted, deteriorated and in need of replacement. To the extent of available funding (labor, materials and equipment estimate), spare parts and parts identified by the COR as “very poor condition to be removed” shall be removed and disposed, including (quantity) (3) Side Assembly; (6) Side Truss; (2) Expansion Assembly; (2) Magazine Elevator Doors. Haul and dispose of stockpiled and miscellaneous rubbish, including e-waste: (35 yards). Dispose of one abandoned fiberglass portable toilet unit. And as directed by the CO, replace miscellaneous existing wood blocking with new plastic lumber nominal 6x6 blocks cut to length as required for the following items stored on site: (quantity) (2) elevator doors; (2) radar units; (3) rocket motor units; include allowance for (5) spare parts. Dispose of existing wood blocks.

The Perimeter Fence and Exclusion Area Fence needs to be repaired with an allowance for new replacement 45º arms, and 920 linear feet of three-strand barbed wire needing to be re-hung (total both fence lines).

The Generator Building (FA966) is an 820 sq. ft (20’-0” x 41’-0”) concrete block building constructed in 1965. A new modified bitumen roof with cap sheet and gravel topping to match the existing (820 sf), including replacement and painting of new metal roof flashings (122 lf), trims and appurtenances, and including stabilization, reinstallation and painting of metal ventilators, is needed.

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. Historic exterior vapor lights need repairs (3 units); metal gutters and downspouts need repairs (16 lf); a small section of concrete block at the roof needs repair (8 sf); exterior of the building needs to be repainted (2400 sf).

The Flammable Storage Building (FA972) is a 54 sq. ft (7’-3” x 7’-3”) concrete block storage building constructed in 1961. A new modified bitumen roof with cap sheet and gravel topping to match the existing (64 sf), including replacement and painting of new metal roof flashings (36 lf), trims and appurtenances, and the door needs to be rodent-proofed. There is an OPTION for repairs to roof framing and fascia, and painting the exterior of the building (230 sf).
