 (from Ch. 24, par. 11-48.3-24)Sec. 11-48.3-24.         All contracts for sale of property of the value of  more than $2,500 or for a concession in or lease of property, including air  rights, of the Authority for a term of more than one year shall be awarded  to the highest responsible bidder, after advertising for bids. All  construction contracts and contracts for supplies, materials, equipment and  services, when the expense thereof will exceed $2,500, shall be let to the  lowest responsible bidder, after advertising for bids, excepting (1) when  repair parts, accessories, equipment or services are required for equipment  or services previously furnished or contracted for; (2) when the nature of  the services required is such that competitive bidding is not in the best  interest of the public, including, without limiting the generality of the  foregoing, the services of accountants, architects, attorneys, engineers,  physicians, superintendents of construction and others possessing a high  degree of skill; (3) when services such as water, light, heat, power,  telephone or telegraph are required.All contracts involving less than $2,500 shall be let by competitive  bidding to the lowest responsible bidder whenever possible, and in any  event in a manner calculated to insure the best interests of the public.In determining the responsibility of any bidder, the Board may take into  account the past record of dealings with the bidder, experience, adequacy  of equipment, ability to complete performance within the time set, and  other factors besides financial responsibility, but in no case shall any  such contracts be awarded to any other than the highest bidder (in case of  sale, concession or lease) or the lowest bidder (in case of purchase or  expenditure) unless authorized or approved by a vote of at least  7 of the members of the Board, and unless such action is  accompanied by a statement in writing setting forth the reasons for not  awarding the contract to the highest or lowest bidder, as the case may be,  which statement shall be kept on file in the principal office of the  Authority and open to public inspection.From the group of responsible bidders the lowest bidder shall be  selected in the following manner: to all bids for sales the gross receipts  of which are not taxable under the "Retailers' Occupation Tax Act", approved  June 28, 1933, as now or hereafter amended, there shall be added an amount  equal to the tax which would be payable under said Act, if applicable, and  the lowest in amount of said adjusted bids and bids for sales the gross  receipts of which are taxable under said Act shall be considered the lowest  bid; provided, that, if said lowest bid relates to a sale not taxable under  said Act, any contract entered into thereon shall be in the amount of the  original bid not adjusted as aforesaid.Contracts shall not be split into parts involving expenditures of less  than $2,500 for the purposes of avoiding the provisions of this Section, and  all such split contracts shall be void. If any collusion occurs among  bidders or prospective bidders in restraint of freedom of competition, by  agreement to bid a fixed amount or to refrain from bidding or otherwise,  the bids of such bidders shall be void. Each bidder shall accompany his bid  with a sworn statement that he has not been a party to any such agreement.Members of the Board, officers and employees of the Authority, and their  relatives within the fourth degree of consanguinity by the terms of the  civil law, are forbidden to be interested directly or indirectly in any  contract for construction or maintenance work or for the delivery of  materials, supplies or equipment.The Board shall have the right to reject all bids and to readvertise for  bids. If after any such advertisement no responsible and satisfactory bid,  within the terms of the advertisement, shall be received, the Board may  award such contract, without competitive bidding, provided that it shall  not be less advantageous to the Authority than any valid bid received  pursuant to advertisement.The Board shall adopt rules and regulations to carry into effect the  provisions of this Section.
