Attachment 3 – Statement of Work

NASA/Glenn is issuing this solicitation to determine the potential of small businesses capable of meeting NASA/Glenn’s requirements for metallic materials in support of our research and development programs.

A brief description of requirements are as follows:

1. Furnish all personnel, facilities, services, equipment, supplies, materials, and transportation

2. Must meet strict research schedules

3. Work to specifications such as (but not limited to) Government-furnished drawings, sketches or written narratives

4. The Contractor shall conform to various NASA and industry standards/codes as specified in orders. Such standards/codes include (but not limited to) all applicable internal/external NASA Glenn Research Center Management documents.

5. Perform accurate machining and handwork for precision tolerances, fits, and finishes.

Dimensional tolerances will vary with hardware and may range from general (+/- .020 inches, 125 RMS) to tight (+/- .0001 inches, 4 RMS) constraints depending on the nature of the work

6. Manufacture, repair, rework, or modify research and facility hardware to include, but not be limited to; structural members and assemblies

7. Modification of aerospace and aeronautical models

8. Three-day response (or less if required) on requests for quotes

9. The use of Quality Management System

10. The Contractor shall inspect all completed tasks prior to delivery to the Government to ensure compliance with the task order and specified standard. The Contractor shall furnish a final inspection report with completed tasks.
