C. Norman Peterson Co. v. Container Corp. of Am., 172 Cal. App. 3d 628 (1985)
In this case, Container Corporation of America appealed from a trial court judgment in favor of contractor C. Norman Peterson Company (“CNP”). CCA had hired CNP to perform work to modernize a paper mill. During the performance of the contract, numerous errors and changes to plan resulted in significant delays and extra costs. CNP sued for the extra costs associated with the project, claiming the extra costs were caused by CCA’s excessive changes to the plan. CCA argued that both parties were aware at the time the contract was formed that the plan would require significant revisions. The trial court found for CNP, holding that CCA’s excessive changes after the project was commenced constituted breach of contract and abandonment. CNP was allowed to recover its total costs expended and lost profit. CCA appealed.
