Bidders may be given permission to withdraw any proposal after it has been deposited with the Department provided that the Department receives such request in writing prior to the opening and reading of bids. Where the bidder has been the successful low bidder upon one or more projects with the result that the total value of the work exceeds the bidder's prequalification rating, such bidder may withdraw with the approval of the Superintendent one or more of such bids. In order to bring the remaining total within the monetary limits of his prequalification rating. In such case, the Superintendent may, in his discretion, award contracts for the project or projects on which such bids have been withdrawn to the next low qualified bidder.
