Where the Board has approved an application which includes rehabilitation of school building facilities, and the Board thereafter makes a finding that by reason of bids actually received, or for other good cause, it would not be economical or good practice to rehabilitate such facilities or portions thereof, such application and approval shall be considered, retroactive to the original dates thereof, to be an application for, and an approval of, the replacement rather than the rehabilitation of such facilities or portions thereof.
