Builder's Claim for Fixed-Price Contract Revision Due to Unforeseen Hardship

A builder undertook to construct a building and agreed to a fixed price, but later, due to unforeseen circumstances making the execution excessively onerous, the builder sought an upward revision of the price, claiming impossibility of performance under the agreed terms. The court overturned the lower court's decision, reasoning that while a unilateral right to revision based solely on increased difficulty or cost is generally not recognized in fixed-price contracts, the relevant contractual clauses and the application of general principles of contract law, specifically those concerning unforeseen circumstances leading to a significant imbalance, must be thoroughly examined to determine if an equitable adjustment or termination of the contract is warranted, rather than strictly adhering to the initial, now ruinous, fixed price.
