1-1 SUMMARY OF WORK

1-1.1 General.- These specifications, together with the referenced specifications, and standards specified in the Contract Documents, cover the requirements of the Federal Aviation Administration, hereinafter referred to as the Government or FAA, for certain work associated with providing and installing one

50-ft high, self-supporting steel antenna tower with grated work platform and six antenna swing arm mounts, overhead cable tray with Heliax cables, counterpoise grounding and lightning protection.

Work also includes the demolition of one existing 120ft high, 28ft wide cable-supported (guyed) steel

RCL antenna tower, its associated cable anchors and footings, (tower foundations can remain at grade), etc. Work includes the installation of 150 linear feet of 7-ft high security fencing. All work located at the

Bakersville, PA BUEC.

1-1.2 Scope. – The Contractor shall provide the necessary; labor, materials, supplies, and equipment to provide and install: one 50-ft high, self-supporting steel platform antenna tower with 6 antenna swing arm mounts; overhead cable tray with heliax cables, provide and install (12) - 7/8” Heliax coax cables from the shelter to the new antenna tower; excavate and install concrete foundation for the antenna tower, erect the antenna tower along with all associated items; platform, railings, climbing ladder, cable wavequide ladder, heliax cables, antenna swing arm mounts, grounding and lightning protection, install

Obstruction Lighting, etc.; and perform security fencing upgrade and site work as required.

Remove the existing guy cable-supported steel 120-ft high, 28ft wide "H" style tower and all cable guys and anchors and footings (in whole). Remove all communication cables and antenna from the existing tower and above ground cable tray (approx. 10ft span from shelter to tower) and associated supports, connecting to the shelter building. Remove and dispose of the tower in its entirety, including; antenna, cables, conduit, hardware, etc...

Demolition can only begin on the 120ft tower once the newly installed 50-ft tower has been “cut-over” and is "live" and up and running operationally. This "cut-over" and "burn-in" period will be performed by the

FAA personnel. During this timeframe, the Contractor will incur "down-time", before being allowed to proceed with demolition of old tower. Typical timeframe to complete the cut-over and burn-in is two weeks.

Contractor’s basic work flow will consist of:

Site clearing and tree cutting and stump removal

Soil Borings (two), along with soil data/analysis (see Appendix - A)

Install concrete foundation per tower manufacturer’s design drawings.

Install the specified underground counterpoise grounding system for the tower and connect via exothermic cad-welds to existing shelter counterpoise and fencing.

Supply, assemble and erect tower structure per tower design requirements (Appendix - B).

Install overhead cable tray system extending between the existing shelter to the new antenna tower per the contract drawings.

Provide and install one 36” x 36” junction box with angle ground bar, ground cable, and N(F) bulkhead adapters, on the tower platform.

Provide and install cable entry ports thru shelter wall and install heliax cables per drawings.

Provide and install one 36” x 36” shelter junction box with coax surge protection mounted on ground bar, ground cable, and Polyphaser coax surge protectors within shelter interior wall.

Provide and install twelve (12) 7/8” Heliax Andrews cables (PN: AVA5-50FX) from the surge protectors within the shelter j-box to the N(F) bulkhead connectors on tower platform j-box. All

Heliax cables shall be terminated with N(M) connectors. The cables shall be connected to a surge protector/ N(F) bulkhead connector.

Remove the existing steel antenna guyed tower (120ft high, 28ft wide - "H" style).

Remove cable guy wires and their associated concrete anchor foundations (in whole) .

Remove all associated conduits, cables, hardware, etc. above grade at the existing tower.

Install 7-ft high security fencing around new tower and tie into existing fence.

Grade, level and install new topsoil and grass seeding as needed to restore any and all disturbed areas to original conditions / match surrounding conditions.

NOTE: This project will be done in phases; the 1 st phase will be the erection of the new 50ft tower, once completed and fully cabled, the Contractor will have some "down time" (1 to 2 weeks) while the

FAA personnel "cut-over" all equipment and frequencies to the new tower. Once all radios, antenna and frequencies have been cut-over to the new tower from the existing tower and it is up and running on-line (“live”), then the Contractor can proceed with the demolition of the existing tower. The

Contractor should anticipate some “down” time during this process, which may extend for approximately 5 to 10 working days, dependent on weather and air traffic conditions.

Installation Procedure:

During the installation, all work shall be coordinated with the on-site Contracting Officer’s Representative

(COR). A project schedule with anticipated installation and cutover dates shall be submitted to the on-site

COR.

Approved temporary methods consisting of sprinkling, chemical treatment, or similar methods will be permitted to control dust. Dust control shall be performed as the work proceeds and whenever a dust nuisance or hazard occurs.

2-2.4.10.4 Erosion control. - Surface drainage from cuts and fills within the construction limits, whether or not completed, and from borrow and waste disposal areas, shall be graded to control erosion within acceptable limits. Temporary control measures shall be provided and maintained until permanent drainage facilities are completed and operative. The area of bare soil exposed at any one time by construction operations should be held to a minimum.

2-2.4.10.5 Post-construction cleanup. - The Contractor shall cleanup and eliminate any and all signs of temporary construction facilities such as haul roads, work areas, structures, foundations of temporary structures, stockpiles of excess or waste materials, and other vestiges of construction prior to final acceptance of the work.
