Section 573A.1. National emergency.

  In the event work or construction upon a public improvement is stopped directly or indirectly by or as the result of an order or action of any federal or state authority or of any court because of the occurrence or existence of a situation which the president or the Congress of the United States has declared to be national emergency, and the circumstances or conditions are such that it is and will be impracticable to proceed with such work or construction, then the public corporation and the contractor or contractors may, by written agreement terminate said contract. Such an agreement shall include the terms and conditions of the termination of the contract and provision for the payment of compensation or money, if any, which any party shall pay to the other, or any other person, firm or corporation under the facts and circumstances in the case.
