that case, defendant hired plaintiff to build two dredge-hulls. Defendant was to supply materials and equipment at specific times but failed to do so, causing plaintiffs cost of performance to be several times greater than that contemplated by the contract. Plaintiff recovered at trial on a quantum meruit theory, and we affirmed, stating:
"The testimony on behalf of plaintiff tended to establish such changes in the work caused by the failure of the defendant to perform his part of the contract, which made the labor more burdensome and extended the same to two or three times the amount it would ordinarily have been, if the material had been delivered at the time and in the condition agreed upon. Therefore the plaintiff could properly recover upon a quantum meruit 96 Or at 496-97 (citing, inter alia, the Hayden cases).
McDonald does not require the plaintiff to prove that the parties intended to abandon the contract. The effect of the McDonald rule is, of course, to supersede the contract with respect to price; but the parties need not intend that result. Wakefield v. Supple, 82 Or 595, 160 P 376 (1917), predecessor to McDonald, makes this clear. Wakefield was based upon the same facts as McDonald, but plaintiffs theory was oral modification of the contract. We affirmed the trial court’s order in that case setting aside a verdict for plaintiff and granting a new trial on the basis that the evidence did not support a finding that the parties actually agreed to modify. McDonald, on the other hand, is clearly based upon quantum meruit, and not, as Hoffman contends, upon express oral modification.
Cases cited by Hoffman are not in point on this question. Wuchter v. Fitzgerald, 83 Or 672, 163 P 819 (1917), and Dickson v. Emmerson, 154 Or 558, 61 P2d 439 (1936), were based on wrongful termination alone. No question of the defendant’s responsibility for a substantial increase in the cost of performance was involved. The plaintiff in Sweeney v. Jackson County, 93 Or 96, 178 P 365, 182 P 380 (1919), sought recovery
