A Public Building Commission shall provide for the proper safekeeping of its records, subject to the provisions of "The Local Records Act", enacted by the Seventy-second General Assembly, and shall keep a minute book for the recording of the corporate action of the Board of Commissioners. A complete record of the meetings and proceedings of the Board of Commissioners shall be kept in such minute book and such minutes shall be signed by the Secretary of the Public Building Commission. The Commission shall keep a true and accurate account of its receipts and disbursements and an annual audit shall be made of its books, records and accounts. The audit shall be presented annually for review to each governing body under whose resolution the Commission is organized. If an audit is not presented on an annual basis, any or all governing bodies under whose resolutions the Commission is organized may order their own audit of the Commission's books, records, and accounts. The Commission shall cooperate by providing all requested documentation. When an audit is conducted at the direction of a governing body, no more than one audit shall be conducted for all governing bodies under whose resolutions the Commission is organized and the audit shall be paid for from Commission funds. All officers and employees authorized to receive or retain the custody of money or to sign vouchers, checks, warrants, or evidences of indebtedness on behalf of the Commission, shall furnish surety bond for the faithful performance of their duties and the faithful accounting of all monies that may come into their hands, in an amount to be fixed and in a form to be approved by the Board of Commissioners.
