PROVIDE CONSTRUCTION OF NEW TOWER

AND DEMOLITION OF EXISTING TOWERS

for the

PLAINVIEW, TX (PVW)

REMOTE COMMUNICATIONS AIR/GROUND (RCAG)

SITE DETAIL SPECIFICATIONS

The following PVW RCAG specifications should be used in conjunction with the UIS Tower Replacement DB General Specifications (General Specifications) and provide further details and site specific project information pertaining to the work requirements for this Subcontract.

A. Project Location: The PVW RCAG facility is located east of county road V on the west side of the Hale County Airport, on the south side of Plainview, TX. The site presently contains four guyed type towers, all with platform decks at 40’ AGL. The GPS position coordinates for the site are:

Latitude: 34.1691, Longitude: -101.7227 B. Summary of Site Specific Work: The new PVW RCAG tower will have a sixteen (16) antenna mount platform with the deck at 40’ AGL (refer to the tower assembly/erection drawings included in this solicitation). Site specific work to be accomplished by the Subcontractor includes, but is not limited to, the following (refer the General Specifications for antenna mounts marked “NOT USED” and for spare cables):

1. Provide and install an obstruction light located near the center of the platform as indicated in the Subcontract Drawings and per the General Specifications.

2. Construct a new security fence around the site perimeter with twin 8’ gate leaves entrance to the limits as indicated in and in conformance with these specifications, the applicable Subcontract Drawings and General Specifications.

3. Demolition work includes the removal of four guyed type towers, all with platform decks at 40’ AGL. Towers are galvanized steel with no paint.

4. Furnish (unless noted otherwise below) and install new communication cabling, junction boxes, antennas, mounts and all other items as required for the complete installation from the communication equipment in the site shelter to the top of the new tower all in conformance with the applicable Subcontract drawings, General Specifications, this and any other applicable Subcontract documents. Such items include:

i. Sixteen (16) new mounts and identified number of antennas, located in the platform area as indicated in the service layout plan included in these specifications and other above referenced documents. All mount materials will be provided with the Contractor Furnished Material (CFM).

ii. Two (2) total junction boxes for the new cabling, with one mounted within the new work platform and one mounted at the tower base. The tower base junction box (J-box) will be located on the face of the new tower nearest the shelter within 5-10’ of the wall or as otherwise approved. All J-boxes are to have lightning protection (LP) bulkheads with polyphasers. An overhead awning with back panel will be included, mounted to the tower structure to shield maintenance workers from rain and ice when performing work within the base J-box. Awning and support materials will be provided with the CFM.

iii. Twenty (20) complete runs of ½” Heliax cables run out the bottom of the base box into a cable tray with ice shield over to center of tower stair runs (passing under lowest stair run). Heliax will then continue vertically up tower between stair runs and into bottom of the platform J-box (PF J-box). From there, sixteen (16) LMR-400 cables will be installed out the sides of platform J-box (PF J-box) to the antennas via cableways that allow for cable maintenance from above the deck and out the top of the base J-box via 4” conduit in to the radio racks in the shelter. The cable support ladder (for cable runs between stairs from base to PF) and trays/trapeze with ice shield (for cable runs between base J-box and cable ladder) will be provided with the CFM, all other cable supports, cable holders/clips, etc. will be supplied by the Subcontractor. All other cable supports needed for cable runs from the top of the base J-box to the radios/racks inside the shelter (conduit, trays, etc.) are NOT provided with the CFM.

iv. All RF cables must use compatible end connectors. LMR-400 patch cables must not use any adaptors to accomplish gender change or 90 degree bends for connection to polyphasers or radios. Refer project specifications regards spares. Submit type proposed for review/approval prior to obtaining for the work.

v. All miscellaneous appurtenances required to complete the work, i.e.: the cable ends, polyphasers, bulkheads, cable mounting appurtenances/hardware, grounding, etc.

PVW RCAG - SITE PHOTOGRAPHS

SITE FROM N

Good access roads to site. Power line is to south of entrance drive. The NW tower is abandoned and must be removed prior to start of any new tower work. All other towers must remain active during the project – remove them after the trial service period. Old daymark paint must be assumed to contain lead requiring appropriate containment methods during demolition.

SITE FROM W

Tower work area is north of the shelter. Access the area around the west side of the shelter avoiding the power line and other critical site components (use of spotters required when large equipment movements occur near). Replace existing perimeter fence with security type.

SOUTH SIDE FROM SW

WEST SIDE FROM SW

This tower must be removed to create clear space prior to start of any new tower work.

WEST SIDE FROM NW

NORTH SIDE FROM NW

NEW TOWER

Remove this tower prior to any new tower work.

NEW TOWER

VIEWS OF NORTH WALL FROM N

4” GRSC with LMR-400 cables in from tower base J-box to radios thru south wall. End new conduit within 3” of wall surface. From there, install new cables over to radios using existing supports, providing new as needed to result in 1’-2’ unsupported gap at wall for potential filter installation during trial service period. Shelter walls are CMU type with insulated vinyl siding.

NW INTERIOR CORNER

SW INTERIOR CORNER

Use two spare breakers (one for stair and PF lights and one for PF outlet) and install 3/4” GRSC (may be EMC inside shelter) w/ 3, #12 conductors each circuit. Route to tower as approved by RE. Maintain 15” min. clearance from parallel runs of signal cabling along power run.

EXISTING N SHELTER J-BOX

(similar J-Box on south wall)

Demolition work after trial service period includes removing all existing cables and J-boxes inside shelter (overhead trays may be left with RE approval for FAA salvage use). Cut, fill with foam and cap cable conduits near walls and floors. Remove cable vaults outside completely and fill hole with compacted soil.

Deliver this antenna to RE for FAA salvage during demo work.
