1.0 INTRODUCTIONS

The RBL RCO is located in vicinity of Red Bluff Municipal Airport, at Red Bluff, California. The purpose of this project is to install 2 new TILT-DOWN Antenna Towers to replace 3 existing antenna towers.

2.0 SCOPE OF WORK

Provide all labors, materials, transportations, and other services necessary to dig foundations and install 3 concrete pull boxes, install new tilt-down antenna masts and install trenchless underground conduits and pull power and Coax cable.

All pull boxes and antenna components, coax cables, connectors and power cables will be provided by the FAA. The contractor must pick up all items from a FAA storage area nearby and transport them to the job site. The location of the antenna foundations and trenching rout is shown on the attached sketch but the exact locations shall be field determined.

The project includes but it is not limited to following:

• Pick up and transport to the site a set of Frangible Antenna System, pull boxes from storage area located in administration building. Each pull box weigh about 2000 Lbs which may require a crane for installation.

• Layout and mark the location the antenna foundation as shown on the attached schematic sketch.

The exact location of the foundations must be field determined.

mailto:michael.kwong@faa.gov

• Saw cut concrete slab, an asphalt paving from the building to the pull box as shown on the project sketch.

• Excavate a trench 9’x9’, 24’ deep and install a concrete foundation for each antenna system, Refer to the attached Sketches for the concrete foundation and drawing CD-D-7778 for detail information for the antenna foundation and mast installations. The antenna masts shall be aligned in north-south track and in direction of each other.

• Excavate and install 3 pull boxes.

• Provide and install Polyethylene – PVC Conduit to AS/NZS 2053 Heavy duty conduits for underground cables by Horizontal Directional Drilling. The conduits shall be 1-1/2” for the power and 4” for the RF cables. The conduits must be extended to the power panel and equipment racks inside the equipment room. The point of access into the equipment room will be field determined.

**See note below.

• Install and assemble the antenna system.

• Provide and install lightning protection systems, consists of 30” long x ½” blunt tip, nickel plated air terminal and adapter, 7/16” braded cooper wire down conductor & fasteners. In addition provide and install ground counterpoise around the antenna mast including four (4) ½” cooper ground rods 10’ long at the corners of the platform and connected to #4/O cooper conductors. All conductors must be exothermically welded to the ground rods.

• Install RF and power cables from equipment room to the antenna masts. Final termination of the RF cables ends and power cable at the power panel will be terminated by the FAA.

• Provide and install lightning terminal at the top of the mast and down conductor to grounding counterpoise. Install Lightning conductor outside antenna mast.

• Install new obstruction lights and connect the circuit to the power disconnect circuit breaker inside the equipment room.

• Schedule a facility outage with POCC for RCO and disconnect all circuits.

**NOTES:

1- Prior to start of the work the contractor shall identify and mark all underground utilities along the route to prevent damage to property and provide clearance required to those services. The correct fittings, conduit alignment, route depth to be used for cable pulling pits.

2- The polyethylene pipe conduit specified has proved to be adequate for the minimum depths required.

However, deeper installations including crossing under built-up roads, may require a thicker wall conduit due to the deformation caused by factors such as the high bearing pressure of the ground water. The Contractor is responsible for assessing whether or not the specified conduit is adequate for the particular application and is to provide a conduit of sufficient wall thickness to ensure undue deformation does not occur. As a minimum, conduit shall be polyethylene pressure pipe complying with AS/NZS 4130, having minimum performance equivalent to PE80 material, classification PN10.
