MAINT.

1. PERFORMANCE WORK STATEMENT

2. INTRODUCTION

The Contractor shall furnish the necessary personnel, material, equipment, and facilities (except as otherwise specified) to perform the following Performance Work Statement. The Government requires Contractor technical evaluation and support for life-cycle maintenance and catastrophic recovery of the existing radar towers in its weather radar network.

3. BACKGROUND

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 Naval Meteorological and Oceanography Command (NMOC), and DOT; Federal Aviation Administration (FAA). The NEXRAD Program has deployed 160 operational and 2 non-operational (training, test, and repair) towers supporting the Weather Surveillance Radar - 1988 Doppler (WSR-88D) weather radar systems throughout the United States and various overseas locations. Currently only NEXRAD radar sites operated by the DOC and DOD are participating in this tower restoration contract. DOT has an internal depot team conducting tower maintenance on their towers.

The WSR-88D Radar Operations Center (ROC) has support management responsibility for these radars for the tri-agency NEXRAD program. Part of the support management responsibility associated with these radars is the maintenance of the tower structure in a fully operational condition to ensure the mission of the tri-agency radar network can be continuously met. Timeliness of tower repairs, both routine as well as catastrophic failure recovery, is critical to the successful completion of the NEXRAD mission.

Since 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 contract award.

The list of all 160 WSR-88D sites and their locations is provided Attachment “2”.

4. SCOPE

This Performance Work Statement provides for initial WSR-88D tower inspection and engineering evaluation. Based on the results of these evaluation services, this work statement provides for the WSR-88D tower repair services for timely restoration of the inspected tower to a like new condition.

Restoration may include, but is not limited to, replacement of structural components, replacement of fasteners, repair/replacement of lightning protection system components, corrosion removal, cleaning, painting, and repair/replacement of galvanic coatings, and tower foundation replacement/repair.

Preventative measures to protect the tower from other issues besides weather related ones may also be required, e.g., bird proofing and power washing chloride deposits. Although the government does not require the use of OEM parts, the contractor must specify any proposed replacement components which are not OEM parts, and demonstrate to the government’s satisfaction that the substitute part is interchangeable and of the same quality of the like OEM part. Finally, this work statement provides for the delivery of WSR-88D Tower Engineering Data and Engineering Change Proposals resulting from any modifications to the documented tower configuration.

5. WSR-88D TOWER INSPECTION AND ENGINEERING EVALUATION CONTRACT LINE

ITEM NUMBER (CLIN) 0001 (Option Periods – 1001, 2001, 3001, 4001)

Upon receipt of a task order (marked ROUTINE or URGENT) for a specific WSR-88D Tower site or sites, the Contractor shall provide WSR-88D Tower inspection and engineering evaluation for the individual tower(s) and provide a written report in Contractor format in accordance with Contract Data Requirements List (CDRL) A001, (Attachment 5) of the original installation and current condition of each inspected WSR-88D Tower and associated hardware including foundations, waveguides, supports, ladders, conduits, power and control circuits/conductors, lightning arrest system, and fasteners.

An urgent task order may be initiated in response to a catastrophic event, a suspected corrective maintenance requirement, or a Government engineering concern requiring Contractor engineering evaluation. For an urgent task order inspection and Engineering Evaluation requires the Contractor on site for inspection within a 48 hour period for sites within the Continental United States and 96 hours for sites outside the Continental United States.

As part of the inspection process, the Contractor shall perform galvanic coating thickness, structural member thickness measurements, ground resistance measurements, and provide an overview of the tower electrical conduits, electrical boxes, tower base perimeter fence, stair treads, stairwell lights-assemblies, and concrete foundation condition as part of its corrosion evaluation. Inspections shall be based on the engineering data as specified by the original equipment manufacturer (OEM) Valmont- Microflect for the specific towers under evaluation.

Inspection results shall reflect requirements for correction, if any, of the existing tower condition to restore it to a serviceable, operational and like new condition. Evaluations of corrosion must include a statement addressing the extent of the corrosion and its affect, if any, on the structural integrity of the tower or component(s) under evaluation. The contractor must also provide photographs, which illustrate the severity and extent (i.e. widespread, localized, etc.) of the tower corrosion if corrosion is present. The contractor must address the extent and method of corrosion removal required, tower encapsulation requirements, and other environmental issues related to the proposed repair. The contractor must also select the proposed method(s) of galvanic coating restoration from the methods described in American Society for Testing and Materials (ASTM) A-780, A Standard Practice for Repair of Damaged and Uncoated Areas of Hot-Dip Galvanized Coatings@ dated 4/10/01. Since these towers are highly visible symbols of the National Weather Service, the aesthetic appeal of the completed repair must be considered in addition to the effectiveness of the recommended technique. This CLIN addresses repair or replacement of components regardless of the cause of the damage (severe weather, earthquake, flood, wildfire, corrosion, material failure/fatigue, etc.)

The specific tower installation and repair can range from the replacement of a complete tower to the replacement/repair of any combination of tower components.
