Presolicitation Notice for Tower Maintenance IDIQ
The National Oceanic and Atmospheric Administration (NOAA) is establishing an Indefinite Delivery, Indefinite Quantity (IDIQ) contract for the maintenance and restoration of the Next Generation Weather Radar (NEXRAD) tower network. This requirement, under solicitation 1305M226Q0101, supports a tri-agency program involving the Departments of Commerce, Defense, and Transportation. The work covers 160 operational and two training towers for Weather Surveillance Radar - 1988 Doppler (WSR-88D) systems. Primary tasks include routine inspections, engineering evaluations, and recovery from catastrophic failures to maintain a 96% operational availability rate. While the Radar Operations Center (ROC) manages the program, this contract specifically serves National Weather Service and U.S. Air Force sites. Performance involves rapid response for urgent inspections and structural repairs. This procurement is an SBA set-aside under NAICS 237130. The NEXRAD program is a joint effort between the DOC, DOD, and DOT to maintain WSR-88D towers. This contract supports 160 operational and two non-operational towers. The Radar Operations Center manages these systems, though only DOC and DOD sites are included in this restoration contract; the DOT uses an internal team. The scope includes maintenance and engineering for 160 operational and two non-operational WSR-88D towers. The goal is to maintain a 96% operational availability rate for the tri-agency radar network.

The Next Generation Weather Radar (NEXRAD) program is a tri-agency joint effort of the Department of Commerce (DOC), the Department of Defense (DOD), and the Department of Transportation (DOT). The operational user agencies involved are: DOC, National Weather Service (NWS); DOD, United States Air Force (USAF); and DOT, Federal Aviation Administration (FAA). The NEXRAD Program has deployed 160 operational and 2 non-op...
View moreSince the WSR-88D tower is a rigid structure which supports the critical transmit and receive equipment, the structural integrity of the tower must be maintained to ensure the availability of weather radar data under all circumstances. Factors such as corrosion, loose fasteners, damaged structural components or tower foundations, and others can contribute to the weakening of the tower system and may result in failure of the system to perform its lifesaving function. It is necessary to periodically inspect the soundness of the tower at all WSR-88D sites, which are constantly exposed to the environmental extremes. It may be necessary to conduct impromptu inspections of radar towers, which have been damaged or suspected to have been damaged by a catastrophic event. Additionally, some towers are located at remote mountainous sites with severe weather environments where the wind and ice loading are excessive. These sites are only accessible at certain times of the year for a limited period of time and require frequent maintenance. Timeliness of inspection and subsequent repair are critical in these situations to restore the WSR-88D tower to its original operational condition. WSR-88D radars must be 96% operationally available in order to meet the diverse meteorological missions of the NEXRAD tri-agency partners.
The Government does not own complete data rights associated with the WSR- 88D Tower. The design and engineering data for the WSR-88D Towers are the proprietary property of Valmont-Microflect (CAGE: 29189). The Government does have data rights to the unique as-built drawings for each tower and detailed bills of material for each tower configuration. The Government has available, a set of installation drawings and detailed bills of material to reconstitute any tower height contained within the WSR-88D network for both the Limited Phase Production and Full-Scale Production configurations. These drawings contain references to all Valmont-Microflect part numbers and parts/quantities required to install any tower configuration in the NEXRAD network. All necessary data and drawings currently available to the government will be provided following the contract award.
The Government will establish an IDIQ contract to issue task orders for the following services:
NWS NEXRAD WSR-88D Radar Tower Maintenance in accordance with the terms and conditions contained herein, attached Performance Work Statement (PWS), and applicable Department of Labor Wage Determination(s).
Task Orders issued under this contract may include any of the following contract line items (CLIN):
CLIN 0001 Tower Inspection and Engineering Evaluations for the NWS NEXRAD WSR-88D Radar Towers.
