1 Introduction

1.1 Background

Since the late 1930's the National Weather Service (NWS) has measured vertical atmospheric profiles of pressure, temperature, relative humidity, and wind velocity. The NWS has primarily used balloon-borne sensors for ‘upper air’ atmospheric observations. Atmospheric observations are a key source of data for weather forecasters and computer models.

The NWS currently operates 92 Upper Air Observations Stations throughout the United States and various territories. These stations perform daily Upper Air Soundings by launching balloons. that carry a small instrument package, called a radiosonde, that measures temperature, humidity, wind speed, and wind direction and transmits all this information back to the ground A typical NWS Upper Air Station uses a radiosonde system with manually launched balloons. The system consists of an Inflation Building where the balloons are prepared and a large tracking dish antenna inside a protective dome (called a ‘radome’) to receive the radiosonde data. Typically, the antenna and radome are located on the roof of the Inflation Building but at a few sites the radome is located on top of another building or at ground level.

Figure 1-1 Typical Radiosonde Radomes and Inflation Buildings

The NWS has completed a major project to modernize all its radiosonde systems. The new radiosonde systems no longer require large tracking dish antennas, and all the old tracking equipment is being retired. The radomes that protect the tracking antennas are expensive to maintain. Consequently, NWS wants to remove selected radomes because of annual maintenance expenses.

A number of Upper Air sites inside the continental USA have been identified as candidates for antennas and radome removal (see Appendix A). The NWS is seeking capable contract services to:

· Create plans and cost estimates to safely remove the radomes

· Direct all radome removal, remediation, disposal and cleanup activities

· Ensure roof integrity after radome removal

· Provide design and regulatory documentation

1.2 Objectives

The main objectives of this contract will be combined in two main task elements for each site:

1.2.1 Task Area 1 - Assessment; For each site:

1. Deliver plans to remove the radome and any required refurbishment of the upper-air inflation buildings (UAIB) roof as a result.

2. Deliver plans to dispose of the radome and related materials construction materials

3. Provide a detailed cost estimate to execute radome removal, disposal

1.2.2 Task Area 2 - Execute Radome Removal Process; For each site:

1. Remove the radome and associated materials.

2. Repair/refurbish the roof on UAIB and cover it with a long lasting, durable waterproof membrane.

3. Dispose of all the old radome and related materials in an environmentally responsible manner.

4. Deliver all required follow-on engineering and regulatory documentation (see Appendix B).

The NWS intends to remove as many radomes as possible given the limitations of building conditions, schedule and project funding. Radomes scheduled for removal have been selected under the assumption that the UAIBs are structurally sound, and will not require any significant structural changes or repairs to make the building safe for use after the radome is removed. Major structural changes, repairs, or modifications to any UAIB are considered beyond the scope of this contract task order.

Note: a ‘major structural change’ is defined as the addition or replacement of any support columns, roof beams, roof frames, purlin beams, large sections of roof deck, large sections of building sheathing, foundation sections, floor slabs, and/or masonry repair.

2 Statement of Objectives

2.1 Scope of Work

This Performance Work Statement (PWS) describes the project planning and radome removal work to be performed by the Contractor. It outlines the range of services required to remove the radomes, refurbish the UAIB roofs, and perform site cleanup and inspection. It also provides performance metrics and quality assurance goals.

The Project will begin with a kickoff conference where the Contract Officer Representative (COR), Contractor and the Task Manager will review: a) the preliminary schedule; b) the Project Management Plan; c) report templates; and, d) the UAIB locations. Radome locations are listed in Appendix A.

2.1.1 Task Area 1 - Assessment

At the direction of the Task Manager (and/or COR), the Contractor shall begin planning for assessments at UAIB sites following a schedule developed in coordination with the NWS. The Contractor shall produce removal plans and disposal plans for each selected site, while meeting deliverables as stated in Appendix B. Planning shall be done in coordination with; a) the COR; b) the Task Manager; c) the building lessors (if applicable); d) NWS Regional Facility Managers; and, e) local Upper Air Site Managers.

2.1.2 Task Area 2 - Execute Radome Removal Process

At the direction of the Task Manager (and/or COR), the Contractor shall begin the radome removal process according to the removal plans and disposal plans developed under Task Area 1 following the schedule developed in coordination with the NWS. All on-site work shall be done in coordination with the COR, the Task Manager, the building lessors (if applicable), NWS Regional Facility Managers, and local Upper Air Site Managers.

All work shall be performed in accordance with applicable OSHA safety regulations. Throughout the entire contract, the Contractor shall provide bi-weekly updates on the status of the radome removal plans and removal activities to the COR and Task Manager as specified in Appendix B.

2.1.3 Change of Scope Notification

Major structural changes to any UAIB are considered beyond the scope of this contract task order. The Contractor shall immediately notify the Task Manager and the COR if at any time they discover there are structural flaws or damage that will require corrective action to make the building safe for use after the radome is removed.

Notification shall consist of an email and a phone call describing the problem. The Contract Officer (CO) may issue a stop-work order if warranted.

The Contractor shall then send a follow-on memo that gives a comprehensive description of the problem, identifies possible corrective actions, and provides a preliminary estimate of additional costs, no later than 10 business days after notifying the Task Manager and the COR.

2.2 Contract Kickoff Conference

The Contractor shall attend and support a contract kickoff conference held at the Sterling Field Support Center, VA. The objectives of the kickoff include:
