Definition
Engineer B supervised test pile driving that used a vibratory hammer not used in the original driving, did not replicate the required depth of penetration, and allowed pre-record hammer drops that broke the pile bond, then drew conclusions about original pile adequacy without disclosing or accounting for these deviations.
Properties
Instance of
MethodologicalConsistencyPrinciple
http://proethica.org/ontology/intermediate#MethodologicalConsistencyPrinciple
Applied to
Test pile driving program designed to assess original 90-pile foundation adequacy
Balancing with
Practical constraints on replicating original site conditions
Concrete expression
Engineer B supervised test pile driving that used a vibratory hammer not used in the original driving, did not replicate the required depth of penetration, and allowed pre-record hammer drops that broke the pile bond, then drew conclusions about original pile adequacy without disclosing or accounting for these deviations.
Confidence
0.88
Interpretation
The test conditions deviated materially from the original pile driving conditions in multiple respects, undermining the validity of comparisons between test results and original pile performance. The principle required disclosure of these deviations and qualification of conclusions accordingly.
Tension resolution
Where original conditions cannot be fully replicated, the engineer must disclose the deviations and qualify the conclusions, not present results as if the test were a valid replication.

After the 30 day set up, the driving hammer was dropped several times to start the hammer before the record of blow counts commenced. In the opinion of Engineer A's geotechnical consultant, this would have broken the pile bond and undervalued the skin friction value reported by Engineer B's tests.
Driving conditions were not duplicated in driving the test piles in that a vibratory hammer was used for the test piles and not used in the original driving.
The test piles were not driven to the same depth of penetration that apparently was required for the plug to form in the original piles.
