We have recently engaged a well known, international company to carry out integrity (sonic echo) testing of bored end-bearing piles installed on one of our contracts.
As there were no significant impedence changes shown in the results of the tests on the P.I.T. machine, we were reasonably confident that the installed piles were acceptable. However, further to analysis of the results, we have received only a very small (1 page) report from this company stating that "All piles have been succesfully tested and no significant defects have been found".
Does this lack of information strike anyone else as odd? Whilst I have absolutely no reason to doubt the integrity of the statement in the report, on previous contracts we have been provided with a full report, showing graphs for each pile tested using this method.

Usually we use the sonic echo test as a confirmatory test. It is preferable to use the frequency response test and only if data is diificult to interpret do we carry out a sonic echo test. Just a thought though.
