Any type of contract which will promote the best interests of the City may be used with the following limitations. A cost plus a percentage of cost contract is prohibited, and a cost reimbursement contract may be used only if a determination is made in writing that such contract is likely to be less costly to the City than any other type or that it is impracticable to obtain the materials, services or construction required except under such a contract.
