Northwest Construction, Inc., made a contract with the state of Washington for highway construction. Part of the work was turned over under a subcontract to Yakima Asphalt Paving Co. The contract required that any claim be asserted within 180 days. Yakima brought an action for damages after the expiration of 180 days. The defense was that the claim was too late. Yakima replied that the action was brought within the time allowed by the statute of limitations and that the contractual limitation of 180 days was therefore not binding. Was Yakima correct?
