Battle Mountain, NV CARSR Antenna & Radome Installation

Introduction and Overview This is an urgent and compelling requirement to support FAA Mission of Battle Mountain, NV ARSR-2 radar site. An antenna system and radome must be installed as soon as possible to restore FAA mission requirements.

The purpose of this requirement is for crane services to lift a beacon antenna, equipment, and radome structure onto the antenna deck.

Background On December 27th, 2022, the Battle Mountain (BAM), NV, CARSR system experienced an unscheduled outage, resulting in the loss of both Radar and Beacon Data Services (RDAT & BDAT). The Common Air Route Surveillance Radar (CARSR) is a long-range L-band radar with a range of 200 nautical miles. The CARSR has as its purpose the detection and tracking of aircraft that are Enroute from one airport to another.

BAM CARSR is located on the 9,600ft peak of Mt Lewis in Nevada and routinely experiences high winds, snow and ice during the winter season. The Airway Transportation Systems Specialist (ATSS) access the facility via snow-cat located at the Saddle snow-cat shelter, approximately 1.2 miles from the site. FAA Field Maintenance Program (FMP) crews only plow the roads to provide access the snow-cat shelter.

The Remote Maintenance and Monitoring (RMM) status for the CARSR system indicated an open antenna interlock. While attempting to access the facility, Wednesday, January 11th, 2023, the snow drifts exceeded the 20ft marker poles used to guide the snow-cat driver safely to and from the facility, preventing the ATSS from site access. Prior to returning, the visibility at the Saddle was sufficient to observe a catastrophic radome failure that encloses the Radar, Beacon and communication antennas.

On March 16th 2023, all radio communication links were lost, FAA, DOD and AT&T, from the Battle Mountain, NV location, causing Air Traffic to declare an Air Traffic Control (ATC) Alert for sectors 42 and 44. This alert requires that all commercial and civilian air traffic to be re-routed around the affected sectors. Airway Transportation Systems Specialist (ATSS) observed via helicopter that the CARSR/BI-6 antenna collapsed onto the communication equipment that provides the radio service to Air Traffic and other customers.

Scope of Work The vendor must provide crane, crane operator(s), and incidentals to lift antenna beacon, equipment, and radome structure from ground and or trailers to antenna tower deck (75ft) that is located on Battle Mountain, NV.

Crane lifts would be for the following:

Antenna Beacon: estimated at 1500lbs / dimensions of 28’x4’x8’ lifted from the ground/trailer and placed on 75’ tower

Spanko Gantry Crane: 4 pieces each under 500lbs / largest dimension would be a 10’ beam lifted from the ground/trailer and place on 75’ tower

Radome Structure: estimated at 13,600lbs / 45’ tall / Outside diameter is 59’ lifted from the ground and placed on 75’ tower

Note: Radome will have 80’ long lifting straps to assist the lift
