The purchasing procedure of the school district shall not only ensure the best possible price for goods and services, but shall also operate efficiently and economically. The construction of facilities, which may exceed an expenditure of $40,000 shall be advertised and submitted for bid in the manner required by law. This limit does not apply to the acquisition of existing buildings, purchase of new sites or site expansions by the district. Other purchases or contractual services may be advertised and submitted for bid as directed by the board or when, in the opinion of the superintendent, the welfare of the district will be served. All bids must be submitted in sealed envelopes, addressed to the board and plainly marked with the name of the bid and the time of the bid opening. Bids shall be opened and examined publicly.
The board reserves the right to reject any or all bids or any part of any bid and accept that bid which appears to be in the best interest of the school district. The board reserves the right to waive any informalities in any bid. Any bid may be withdrawn prior to the scheduled time for the opening of bids. Any bid received after the time and date specified shall not be considered.
