80LARC26R0004

NASA Langley Research Center (LaRC) has a requirement for Blanket Purchase Agreements (BPA) for general and precision machining/fabrication. This BPA will allow NASA LaRC to easily acquire various required fabrication and machining services over the next 5 years which generally have short response times to meet critical research project requirements at NASA LaRC.

A brief description of requirements are as follows:

� Furnish all personnel, facilities, services, equipment, supplies, materials, and transportation � Must meet strict research schedules � Work to specifications such as (but not limited to) Government-furnished drawings, sketches, or written narratives � The Contractor shall conform to various NASA and industry standards/codes as specified in task orders. Such standards/codes include (but not limited to) all applicable internal/external Langley Management System documents.

� 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

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

� Modification of aerospace and aeronautical models � Three day response (or less if required) on requests for quotes � General fabrication and precision machining � Quality Management System � 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.

Typical materials to be worked shall include (but not limited to) the following:

� Metals, including aluminum and its alloys, copper, brass, carbon steels, stainless steels, alloy steels, titanium, nickel, nickel alloys, and other special alloys.

� Non-metallic materials, including fibrous reinforced polymeric, plastic, ceramics, glass, carbon, and fiberglass of composites with epoxy, phenolic, polyester, polyamide, and polimide resin and adhesive systems

� Metal matrix filament reinforced plastics, including boron, carbon, graphite, and tungsten filaments � Advanced state-of-the-art metallic, polymeric, and hybrid composites � Wood, including epoxy or polyester impregnated products � Combinations of these materials
