(70 ILCS 2805/81) (from Ch. 42, par. 447.45)
    Sec. 81. Bond of contractor and suit on bond. Except as otherwise provided in Section 9-2-113 of the Illinois Municipal Code, as now or hereafter amended, the successful bidder for the construction of such an improvement shall be required to enter into a performance and labor and materials bond in a sum equal to 100% of the amount of his bid with sureties to be approved by the committee. This bond shall be filed with the district's clerk and shall be deemed to contain the provisions set forth in Section 1 of "An Act in relation to bonds of contractors entering into contracts for public construction", approved June 20, 1931, as now or hereafter amended. When entering into the contract for the construction of an improvement the bond shall provide that the contractor shall well and faithfully perform and execute the work in all respects according to the complete and detailed specifications, and full and complete drawings, profiles, and models therefor, and according to the time and terms and conditions of the contract, and also that the contractor shall promptly pay all debts incurred by him in the prosecution of the work, including those for labor and materials furnished.
    Suit may be brought on the bond in case of default or failure to pay these debts promptly by and in the name of the district for all damages sustained either by the district or by any person interested, or for the damages sustained by the district and all parties in interest or by any beneficiary or party interested in the name of the district for the use of the party interested as beneficial plaintiff to recover for the labor and materials furnished. However, in no case shall costs be adjudged against the district in any suit brought by any party in interest wherein the district is the nominal, but not the beneficial, plaintiff.
    In advertising for bids or proposals for the construction of such an improvement, the committee shall give notice that such a bond will be required, and all bids or proposals shall be deemed to contain an offer to furnish such a bond upon the acceptance of such a bid or proposal.
