Prior to making partial or final payments on contracts, the Manager shall certify that the conditions of the contract for which the payment is to be made have been complied with.  In the case of partial payments, such payments shall be made in accordance with estimates of the amount and value of the work accomplished.  The certificates or estimates shall include only the amount and value of the work accomplished and materials used since any preceding estimate.  Such certificates or estimates shall further indicate that a greater portion of the contract has been performed by the contracting party than that which is represented by the requested partial payment, in addition to any preceding partial payments.  Upon receiving such certificates, estimates or invoices, properly certified, the Director of Finance shall then issue warrants in payment.  A percentage may be withheld by the Manager on any contract as a guarantee of proper performance of the contract.
