We have reviewed all nail test results and have concluded that they are acceptable, including the nail in question. Given the high degree of variability of the site conditions, the single nail that achieved a lower pullout resistance was indicative of a localized condition and was not unexpected during the design of the walls. The overall factor of safety for this section of wall was still acceptable. Thanks. Joel R. Clark, P.E. Craig Olden, Inc.
