Which entity conducts the test on the RT sample when QC and VT do not meet the maximum density specification?

Explanation:
Independent verification is used when the contractor’s QC tests and the engineer’s VT tests both fail to meet the maximum density specification. In that situation, the retest sample (RT) is examined by SMO to provide an objective, unbiased result. The SMO’s test on the RT sample confirms whether the density requirement is truly unmet or if the discrepancy was due to testing variability. This independent test is the authoritative check used to decide next steps.
