Decision Question
When a comparative test pile driving program uses materially different equipment and procedures than the original installation, what obligation does the supervising engineer bear to ensure methodological fidelity or disclose departures that affect the validity of the comparison?
Focus
Engineer B designed and supervised a comparative test pile driving program using a vibratory hammer and non-replicated penetration depth conditions, when the original piles were driven under different conditions, and then drew adverse conclusions from the test results without disclosing the methodological departures that made the comparison structurally invalid.
Option1
Replicate the original pile driving conditions — including hammer type, penetration depth requirements, and blow-count recording protocols — in the test program, or disclose all material departures in the report and qualify the adverse conclusions to reflect the limits of comparability
Option2
Proceed with the available equipment and field conditions, disclose the vibratory hammer substitution and depth variations in the report's methodology section, and present the test results as indicative rather than definitive comparators pending a fully replicated test program
Option3
Apply professional judgment that the vibratory hammer and modified depth protocol are sufficiently equivalent for the purposes of the evaluation, proceed without disclosure of the departures, and issue conclusions based on the test results as if they were directly comparable to the original installation
