Fla. Stat. § 159.32
Contracts for the construction of the project may be awarded by the local agency in such manner as in its judgment will best promote free and open competition, including advertisement for competitive bids in a newspaper of general circulation within the boundaries of the local agency; however, if the local agency shall determine that the purposes of this part will be more effectively served, the local agency in its discretion may award or cause to be awarded contracts for the construction of any project, or any part thereof, upon a negotiated basis as determined by the local agency. The local agency shall prescribe bid security requirements and other procedures in connection with the award of such contracts as in its judgment shall protect the public interest. The local agency may by written contract engage the services of the lessee, purchaser, or prospective lessee or purchaser of any project in the construction of the project and may provide in the contract that the lessee, purchaser, or prospective lessee or purchaser may act as an agent of, or an independent contractor for, the local agency for the performance of the functions described therein, subject to such conditions and requirements consistent with the provisions of this part as shall be prescribed in the contract, including functions such as the acquisition of the site and other real property for the project; the preparation of plans, specifications, and contract documents; the award of construction and other contracts upon a competitive or negotiated basis; the construction of the project, or any part thereof, directly by the lessee, purchaser, or prospective lessee or purchaser; the inspection and supervision of construction; the employment of engineers, architects, builders, and other contractors; and the provision of money to pay the cost thereof pending reimbursement by the local agency. Any such contract may provide that the local agency may, out of proceeds of bonds, make advances to or reimburse the lessee, purchaser, or prospective lessee or purchaser for its costs incurred in the performance of those functions, and shall set forth the supporting documents required to be submitted to the local agency and the reviews, examinations, and audits that shall be required in connection therewith to assure compliance with the provisions of this part and the contract.
