(d) 4 piles were uninterpretable meaning that of 9 piles which were interpretable, 1 is probably too short and 1 may well be too short (pp. 4, 11, 21, 38).
56 Assuming there were in the order of 65 piles in total, only a relatively small number were tested. The problems identified were significant and indeed alarming having regard to the small number tested.
57 Sonic testing constitutes a preliminary form of testing. As stated in Annexure "B" to Dr. Burman's affidavit dated 25 October 2004 "Sonic testing of the piles as they have been installed at this site is at best problematic and … the interpreted results are of limited credibility, albeit possibly the best that can be done in the circumstances."
58 All that can be safely said is that the sonic testing did not reliably demonstrate that all of the CP2 piles tested had been excavated and constructed to the required depth so as to give the plaintiff the required assurance contemplated by the Deed and the WMS.
59 That Mr Ryan's evidence was unsatisfactory was not contested before Nicholas J, nor was it contested on the instant application. Some of the highlights of that evidence and of the defendant's concessions before Nicholas J were:
· at the beginning of the hearing on 29 October 2004, Leduva admitted in open Court (TS 126.41-46):
"That it is clear that some of the evidence given by the key witness, Mr Ryan, was inaccurate and confused to say the least and in consequence of that, we prepared a further affidavit by Mr Ryan setting out what he says to be the exact position dealing with matters line by line."
· his further evidence only landed him in even further contradictions in his evidence. Later on the same day Leduva submitted (TS 135.24-29):
"What is suggested is that we have failed to give the documentation and it is surrounded by suspicion and uncertainty and that the Rail has not properly discharged its obligation to ensure that it is all totally safe and so on. So much could not be gainsaid."
· two sets of certificates relating to piles had been produced by Mr Ryan, being (i) the Certificates of Underground Construction (the form required by the WMS) and (ii) certain "Structural Certificates" which were not required by the WMS;
· no Certificates of Underground Construction had been provided in relation to CP1 piles;
· in his earlier evidence Mr Ryan attempted to give the impression that he actually measured the depth of some CP1 holes. As it turned out in further cross-examination, he actually measured none;
· the failure to provide Certificates of Underground Construction for the CP1 piles was a breach of the Deed and of Rail Corp's directions. Mr Ryan had made no attempt, in any of his affidavits, to explain why no such certificates have been provided, nor has Leduva provided any explanation;
· his evidence was inconsistent as to whether he was present for the drilling of the CP2 piles;
· initially Mr Ryan's unqualified evidence was that the dates of his structural certificates indicated the dates on which he was on site. When confronted with his invoices and car logs which indicated he was not on site on certain days referred to in his certificates, he accepted the certificates were mistaken in that respect;
· Leduva acknowledged that the documentation was "not up to scratch" (TS 82.20) and that there were "plainly shortcomings" and that Leduva's witnesses "when cross-examined on the matter said some things that were pretty silly and obviously wrong, which is true";
· Leduva referred to "the unhappy matter of the documentation". This concession was undoubtedly properly made at the time (27 October 2004). On 29 October 2004, Mr Ryan gave further evidence reinforcing the correctness of the concession. At TS 201, Mr Ryan accepted the Certificates of Underground Construction, at the time he signed them:
i. did not record the piers to which the certificates related;
