(A) All contracts for purchases by the village shall be in compliance with the statutes of the state.
(B) Any work or public improvement which is not to be paid for in whole or in part by special assessment or by special taxation when the expense thereof will exceed $4,000 shall be constructed either:
(1) By a contract let to the lowest responsible bidder after advertising for bids in the manner prescribed by ordinance and statutes, except that any such contract may be entered into by the proper officers without advertising for bids if authorized by a vote of two-thirds of all Trustees then holding office; or
(2) If authorized by a vote of two-thirds of all the Trustees or Board members then holding office, the Superintendent shall supervise and cause to be carried out the construction of the work or other public improvement and shall employ exclusively for the performance of all manual labor therein, laborers or artisans whom the municipality shall pay by the day or hour; and all material of the value of $4,000 and upward used in the construction of the work or the public improvement shall be purchased by contract let to the lowest responsible bidder in the manner prescribed by the code of the village. However, nothing contained in this chapter shall apply to any contract with the village with the federal government or agents thereof.
