    Sec. 11k. Competitive bidding; notice requirements.
    (a) The board of trustees shall have the power to acquire by gift, legacy, or purchase any personal property necessary for its corporate purposes provided that all contracts for supplies, materials, or work involving an expenditure in excess of $20,000 shall be let to the lowest responsible bidder after advertising as required under subsection (b) of this Section. The board is not required to accept a bid that does not meet the district's established specifications, terms of delivery, quality, and serviceability requirements. Contracts which, by their nature, are not adapted to award by competitive bidding, are not subject to competitive bidding, including, but not limited to:
        (1) contracts for the services of individuals
    
possessing a high degree of professional skill where the ability or fitness of the individual plays an important part;
        (2) contracts for the printing of finance committee
    
reports and departmental reports;
        (3) contracts for the printing or engraving of bonds,
    
tax warrants and other evidences of indebtedness;
        (4) contracts for the maintenance or servicing of, or
    
provision of repair parts for, equipment which are made with the manufacturer or authorized service agent of that equipment where the provision of parts, maintenance, or servicing can best be performed by the manufacturer or authorized service agent, or which involve proprietary parts or technology not otherwise available;
        (5) purchases and contracts for the use, purchase,
    
delivery, movement, or installation of data processing equipment, software, or services and telecommunications and interconnect equipment, software, and services;
        (6) contracts for duplicating machines and supplies;
        (7) contracts for utility services such as water,
    
light, heat, telephone or telegraph;
        (8) contracts for goods or services procured from
    
another governmental agency;
        (9) purchases of equipment previously owned by some
    
entity other than the district itself; and
        (10) contracts for goods or services which are
    
economically procurable from only one source, such as for the purchase of magazines, books, periodicals, pamphlets, reports, and online subscriptions.
    Contracts for emergency expenditures are also exempt from competitive bidding when the emergency expenditure is approved by a vote of 3/4 of the members of the board.
    (b) Except as otherwise provided in subsection (a) of this Section, all proposals to award contracts involving amounts in excess of $20,000 shall be published at least 10 days, excluding Sundays and legal holidays, in advance of the date announced for the receiving of bids, in a secular English language daily newspaper of general circulation throughout the district. Advertisements for bids shall describe the character of the proposed contract or agreement in sufficient detail to enable the bidders thereon to know what their obligations will be, either in the advertisement itself, or by reference to detailed plans and specifications on file at the time of the publication of the first announcement. Such advertisement shall also state the date, time and place assigned for the opening of bids, and no bids shall be received at any time subsequent to the time indicated in the announcement. All competitive bids for contracts involving an expenditure in excess of $20,000 must be sealed by the bidder and must be opened by a member of the board or an employee of the district at a public bid opening at which the contents of the bids must be announced. Each bidder must receive at least 3 days notice of the time and place of the bid opening.
