Service Contract Statement of Work

This contract is to cover maintenance, repair, and calibration for the 50+ Government –owned universal load frames at Glenn Research Center. This equipment resides in the Structures and Materials Division and is used for materials characterization testing for the various programs supporting Space and Aeronautics. Research involving this equipment often involves the utilization of these machines at their resolution limits. Therefore, these machines must function according to their design specifications.

The test equipment covers a wide range of load frames including, but not limited to, servohydraulic, electromechanical and screwdriven machines. The majority of these rigs are 20 and 50 kip uniaxial test systems. There are also several axial/torsion, high frequency uniaxial, and custom-built high frequency/low frequency uniaxial test rigs. The majority of the rigs are controlled by analog MTS controllers, e.g. model 458 servocontrollers. There are also Instron controlled systems as well as MTS digitally controlled systems. An equipment list is available upon request.

This contract shall provide service support to maintain the proper operation of these test rigs. This shall include: identification, repair or replacement of defective electronic and mechanical components, tuning of test rigs, and other necessary repairs to ensure the proper functioning of these rigs. The term “rig” constitutes the load frame, controller, sensors, hydraulic pumps and lines, gripping system, environmental chambers, heating systems, and ancillary equipment, which may include any device connected to the rig and used to conduct the test.

The contractor shall also provide calibration services as requested by NASA on an as needed basis. This may include on-site calibration of LVDTs, RVDTs, extensometers, and load cells under static and dynamic conditions, including the alignment of the load train. All calibration standards and equipment used for this purpose shall be NIST traceable. The contractor shall be compliant with the requirements in ANSI/NCSL Z540-3 and ISO 9001. Also, all load cell calibrations shall be done in the load frame without disturbing the grips, cross-head, or load-train alignment unless otherwise permitted, in writing, by NASA.

The Government estimates an average of one week of onsite service support and calibration activity per month or approximately 12 hours of labor per month for diagnosis and repair and approximately 16 hours of labor per month for calibration of load cells and LVDT’s (aggregate for all machines). Most transducers are on a 2 year calibration cycle, so the work tends to be sporadic (high number of calibrations over short intervals separated by long intervals with no calibrations).”

The contractor must be able to supply evidence of experience in the service and calibration of relevant Government owned equipment and be able to provide references of previous contracts and customer contacts (references) upon request.

*Travel shall only be invoiced for travel costs and trips. The invoice shall have travel tickets attached. The contractor shall only invoice the Government once the work has been completed.
