Ariz. Rev. Stat. § 32-1184 – Interruption of performance of construction contract; damages; termination of contract

A. A contractor licensed under this chapter may interrupt the performance of a construction contract without penalty or liability for breach of contract if any applicable law or rule requires the cessation of work or the contractor encounters any hazardous substance or hazardous material which is required to be removed or contained by any applicable law or rule and either of the following apply:
1. 1. Any applicable law or rule prohibits the contractor from proceeding to remove or contain the hazardous material or hazardous substance unless the contractor is duly licensed and the contractor is not so licensed.
2. 2. The removal or containment of the hazardous material or hazardous substance cannot be accomplished without a cessation of work.
B. A contractor licensed under this chapter whose work is impaired, impeded or prohibited under subsection A may interrupt performance of the construction contract as provided in this section only to the extent of the area affected by the hazardous materials or hazardous substances removed or contained by the owner or as otherwise required by applicable statute or rule.
C. A person who interrupts the performance of a construction contract under subsection A is entitled to reasonable and foreseeable damages caused by the delay unless the existence of the specific hazardous substance or hazardous material is disclosed in writing prior to entering into the contract. The right to damages is conditioned upon notification within a reasonable period of time to the owner of the discovery by the person of the existence of the hazardous material or hazardous substance. This section shall not affect any legal rights and remedies otherwise existing between the parties, including but not limited to rights to damages, setoff and counterclaim.
D. The owner may terminate the construction contract on payment to the contractor, subcontractor or other person whose work is delayed under subsection A of the amount of any services or materials supplied or expended which conform to the contract terms and specifications and the payment of damages subject to the provisions of subsection C to the date of the termination of the contract.
