costs or disbursements, and matter remitted to the Supreme Court, Nassau County, for further proceedings consistent herewith. 11 In March, 1972, plaintiff and defendant Town of Hempstead entered into a contract for the construction of a bulkhead and a dredging and fill operation in order to convert some land into a park and recreation area. On or about January 30, 1973, the town declared plaintiff in default and called upon the surety, Royal Indemnity Company, to complete performance pursuant to its performance bond. 11 Plaintiff thereupon commenced this action to recover damages for alleged breach of contract and
quantum meruit, and claiming damages for extra work performed. The town counterclaimed and brought a third-party action against the surety to recover liquidated damages for late performance. The surety,
inter alia, counterclaimed against the town for extras and brought a fourth-party action against plaintiff for,
inter alia, indemnification. H Following a nonjury trial, the court found that the plaintiff was entitled to recover for the majority of its claims and that the surety was entitled to recover for its completion costs and for extra work performed. We find that a substantial modification is in order. H At the threshold we note that while the town delegated substantial supervisory authority to its retained engineer, pursuant to section GC-35 of the contract, it expressly precluded him from giving oral consent to any work changes. Specifically, the section provided that “no such change shall * * * require the payment of additional compensation to the Contractor, unless it has been made in writing and signed by the Engineer” and that “no oral agreement, conversation, or understanding between the Contractor and the Engineer * * * before or after the execution of the Contract shall affect or modify any of the terms or obligations of the Contract Documents”. 11 The clear purpose of this contractual provision is to obviate any issue as to the credibility of either the contractor or the engineer as to what was or what was not said by either of them. Trial Term erred in declining to enforce the clause as written and there is no basis on this record to impose an estoppel or waiver against the town. Unlike the situations presented in the cases cited by plaintiff (e.g.,
Joseph F. Egan, Inc. v City of New York, 17 NY2d 90 ), the engineer was not a town official who could waive contractual provisions and, indeed, was expressly precluded from doing so. As a matter of law, plaintiff could not rely upon any assurances allegedly made by the engineer. 11 If plaintiff believed that it was necessary to undertake work or provide materials outside the parameters of the contract, it should have secured a signed agreement to that effect. Having failed to do so, it is barred from obtaining recovery for the claimed work changes and extras not supported by a written order (see
Mars Assoc, v City of New York, 53 NY2d 627 , affg
70 AD2d 839 ). 11 In any event, our review of the record indicates that, except for the additional pile lengths, which were the subject of a written change order, the weight of the evidence does not support plaintiff’s claim for further compensation. Since the contract made clear that plaintiff was to rely upon its own investigation of the site conditions, “no recovery for extra work may be had, absent a showing of fraud or misrepresentation as to existing conditions”
(Savin Bros, v State of New York, 62 AD2d 511 , 515, affd
47 NY2d 934 ). We find no evidence of fraud or bad faith (cf.
Kalisch-Jarcho, Inc. v City of New York, 58 NY2d 377 ). The town cannot be held liable for plaintiff’s failure to adequately gauge the costs of performance
(Delma Eng. Corp. v 6465 Realty Co., 39 AD2d 846 , affd
31 NY2d 816 ). H The town did, however, execute a written change order for “[ajdditional footage of timber piling driven for [the] bulkhead deadman system”. Although the footage stated in the order was for 1,460 with the stated unit price of $4 per foot, plaintiffs alleged that, based on an overrun of 4,505 feet at a marine installation cost of $12 per foot, $54,060 was due. The town’s recognition and retroactive acceptance of this wood piling as a legitimate extra warranted
