1. Dustin Developer entered into a signed detailed written contract with Corbin Contractor for the construction of a concrete foundation for the new hospital Dustin is building. The contract provides that Corbin will complete the concrete foundation (in accordance with detailed drawings) at a fixed contract price of $750,000. Although they didn't discuss it, both parties assumed the excavation could be accomplished with earth-moving equipment without the need to do blasting.However, a few days into the job, Corbin discovered bedrock five feet below the surface. The bedrock needs to be blasted in order to complete the project as planned. This is significantly more expensive than anticipated. Based on this, Corbin called a meeting with Dustin to advise him of this newly-discovered problem. Corbin told Dustin he can still complete the project as planned and on time, but due to the newly-uncovered bedrock, it will cost an additional $100,000.

Dustin and Corbin agreed to the additional cost and they signed a written contract modification providing for a revised contract price of $850,000. Corbin completed the work in accordance with the contract and sent Dustin the bill for $850,000. Dustin paid the original price of $750,000 but refused to pay the additional $100,000. Corbin sued Dustin to recover the balance of $100,000.
