Progress Payment Procedures,
reference Procurement Handbook 7460.8  paragraph 6-7 C 2 b

(1) Where progress payments are necessary, the HA shall require the contractor to prepare a construction progress schedule for each project immediately after HA issuance of the notice to proceed.  The HA may require use of Form HUD-5372, Construction Progress Schedule, or other appropriate forms from various professional organizations.  The information shall be realistic and consistent with the information provided by the contractor on the HA-approved schedule of amounts for contract payments and the HUD-approved Project Implementation or Development Schedule, as applicable.
(2) The HA or its architect under contract shall review the contractor's construction progress schedule to determine that the scheduled dates and amount of work to be completed are reasonable and consistent with the contract.  If acceptable, the HA architect shall sign the schedule and forward it to the HA for approval.  Upon approval by the HA, the approved construction progress schedule shall be returned to the contractor.
(3) The HA shall require the contractor to prepare a schedule of amounts for contract payments immediately after execution of the contract.  The HA shall use Form HUD-51000, Schedule of Amounts for Contract Payments.

(4) The HA and its architect shall review the schedule to determine that the scheduled work to be completed by the specified dates and the amount of payment for such work are reasonable.  If acceptable, the HA shall approve and return the schedule to the contractor.  Field Office review is not required.

(5) The HA is responsible for making progress payments to the contractor based on the HA-approved schedule of amounts for contract payments.  Generally, progress payments for acceptable work and materials delivered and stored on the site are made at 30-day intervals.  Field Office authorization of progress payments, based on the approved payment schedule, is not required.
(6) The contractor shall submit a request for payment for each project on Form HUD-51001, Periodical Estimate for Partial Payment.  The request shall be accompanied by the contractor's written designation of a certifying officer.  In addition, the contractor shall submit the following HUD forms or other appropriate forms, if applicable, with each periodical estimate for partial payment: Form HUD-51002, Schedule of Change Orders; Form HUD-51003, Schedule of Materials Stored; and Form HUD-51004, Summary of Materials Stored.

 (7) The HA shall review each contractor request and shall approve the payment if the following conditions have been met; if the contractor requests payment for items which have not been acceptably completed, the HA shall delete those items and adjust the payment accordingly:

(a) the contractor request is consistent with the HA-approved schedule of amounts for contract payments;
(b) the request does not include the amount to be retained by the HA under the contract;
(c) the work covered by the payment has been performed in accordance with the construction documents;
(d) the Form HUD-51001, Periodical Estimate for Partial Payment, has been properly executed and all applicable supporting documentation submitted; and
(e) the contractor has submitted all required reports, such as payroll reports.
The HA shall retain the original Form HUD-51001 and any applicable supporting documentation for its file and return a copy of the HA approved forms to the contractor.
