The board shall have the right to reject any and all bids not suitable to the best interests of the district. In its discretion, the board may readvertise for new bids or negotiate an offered bid, if it is the sole bid received and the negotiated price does not exceed the offered bid for the work as advertised. If two or more bids are the same and are the lowest, the district board may accept the one it chooses. If no bids are received, the district board may proceed to complete the project by force account or contract without further compliance with this article.
