Such determination shall be final and shall be the determination of the awarding body. Upon receipt by it of the notice of the filing of such petition the body awarding the contract or authorizing the public work shall extend the closing date for the submission of bids or the starting of work until five days after the determination of the general prevailing rates of per diem wages pursuant to this section.
