NASA Just Can't Get That Engine Test Stand Thing Right

NASA OIG: Construction of Test Stands 4693 and 4697 at Marshall Space Flight Center

"In an attempt to meet a 2017 launch date for the SLS, NASA expedited construction of the test stands and paid the contractor a premium of approximately $7.6 million to complete construction on a compressed timetable. Moreover, because the stand designs were based on preliminary testing specifications, the requirements and testing capabilities that would be needed were not fully understood when the construction contract was awarded. As the testing requirements matured, NASA modified the contract to meet changing requirements, added additional features, and made other modifications that raised the contract price by $20.3 million. In addition, NASA did not establish adequate funding reserves to cover these changes and therefore had to secure $35.5 million in additional funding over the planned budget. Finally, because NASA did not adequately consider alternative locations before selecting Marshall as the site for the test stands, it cannot ensure it made the most cost-effective decision regarding where to build the stands."

NASA OIG: NASA's Decision Process for Conducting Space Launch System Core Stage Testing at Stennis, earlier post

"In July 2008, the NASA Office of Inspector General (OIG) examined allegations that NASA's plan to build the A-3 test stand at Stennis to test its J-2X engine would duplicate capabilities of an Air Force testing facility in Tennessee. The OIG found NASA failed to follow both its own internal procedures and the process it had agreed to with the Department of Defense (DOD) to avoid costly duplication of test stands when making decisions where to test rocket engines."
