1. INTRODUCTION

The National Weather Service (NWS), National Oceanic and Atmospheric Administration (NOAA) within the Department of Commerce (DOC) manages the Next-Generation Weather Radar (NEXRAD) network high-resolution Weather Surveillance Radar – 88 Doppler (WSR-88D). The NEXRAD are operated by the National Weather Service (NWS), Federal Aviation Administration (FAA) and U. S. Air Force (USAF). NEXRAD detects weather events and is the primary detection system used by the NWS to support issuance of severe weather warnings, and is used by the FAA and USAF to support safety of flight operations.

Equipment required for operation of the NEXRAD radars is contained in three separate pre-cast concrete shelters at each site. The Government requires minor refurbishment of these shelters.

2. BACKGROUND

The NWS requires maintenance of pre-cast concrete radar shelters as part of the shelter maintenance and repair Service Life Extension Program (SLEP). The Program is comprised of up to 160 Doppler radars located within the United States, of which 143 are eligible for SLEP. Each radar site has three pre-cast concrete shelter enclosures, including a Radar Data Acquisition (RDA) Shelter, Generator (GEN) Shelter, and Transit Power and Maintenance Shelter (TPMS), which houses the electronic radar equipment. The shelters at each radar site require periodic maintenance and repairs to provide continued protection of sensitive radar equipment, and ensure longevity of individual shelter enclosures. These shelters have been in service for 11-15 years.

The construction of the three types of shelters are similar in that they are all constructed of concrete panels with exposed aggregate exterior walls and a concrete roof with a rubber protective coating on the roof exterior. All shelters have painted metal doors/frames, ventilation hoods, diesel fuel fill tubes, etc. The RDA and GEN Shelters have caulked joints between concrete panels, whereas the TPMS Shelter does not use caulking in these joints. Photographs of each type of shelter are included in Appendix A. Dimensions of each shelter are contained in Appendix B.

3. SCOPE

The contractor shall provide all material and labor required to complete each maintenance task as described in this Statement of Work.

The procedures and materials to be used for each maintenance task are included with this SOW. All applicable maintenance procedures will be performed on each shelter.

4. GENERAL REQUIREMENTS

All maintenance shall be performed at the site of the equipment shelters (found in Appendix C). The contractor will provide all materials required to accomplish refurbishment of all shelters identified in the task order. The contractor will coordinate arrival and work accomplishment with identified NWS site personnel, and remove all waste materials resulting from the maintenance actions. The five maintenance tasks to be performed under this contract are: cleaning and replacing roof, cleaning and re-sealing aggregate surfaces, repainting metal surfaces, removing and replacing all exterior caulk in joints, and replacing steel doors as required.

Although the Contracting Officer’s Representative (COR) will be the primary Point of Contact (POC) when coordinating execution of task orders, the work site POC will coordinate site entry, inspections, final acceptance, etc.

The exterior maintenance to be performed by the contractor on shelter enclosures is specified for each site location and each shelter at that location and may include:

• Cleaning and sealing of exterior aggregate wall surfaces

• Painting external trims and metal surfaces

• Remove/replace caulking on and around external walls and surfaces

6. MAINTENANCE REGIONS

The NWS Radar Operations Center (ROC) oversees five separate regions requiring shelter refurbishment:

Eastern, Western, Central, Southern, and Department of Defense (see Appendix C).

6.1 DIFFERING CONDITIONS

Due to variable weather conditions at individual sites within each region, the maintenance requirements may vary from site to site, or region to region.

Example a)

Many sites within the Eastern region currently have Rhino brand roofing covering the roofs of their shelters.

These sites may elect to either replace with a Rhino system, or choose the Conklin brand roofing system.

Example b)

Sites located in an environment that is caustic to standard steel doors may elect to replace them with stainless steel doors.

7. MAINTENANCE PROCEDURES

The NWS Radar Operations Center (ROC) developed maintenance procedures to be used by NWS personnel responsible for maintaining these equipment shelters. The procedure for each maintenance action is provided in Appendix E. The contractor shall follow these procedures while performing under this contract. Any deviations must be approved in writing by the COR.

8. QUALITY ASSURANCE INSPECTION POINTS
