The ASBCA’s November 2021 decision in Harry Pepper and Associates, Inc., No. 62038 et al. (Nov. 3, 2021) offers important guidance on the role of live witness testimony in one of the most challenging aspects of differing site conditions claims: proving that the actual site conditions were actually different from those that were expected.

The claims at issue in the case arose from a $36 million task order for the restoration of NASA’s B-2 rocket test stand, which was built in the 1960s as part of the Apollo program and used to test the Saturn V rockets. The restoration was needed so that the B-2 stand can be used to test rocket vehicles for use in NASA’s new moon-launch program, Artemis.
