ARTICLE 5
PROGRESS PAYMENTS
5.1 Based upon Applications for Payment submitted to the Architect by the
Contractor and Certificates for Payment issued by the Architect, the Owner shall
make progress payments on account of the Contract Sum to the Contractor as
provided below and elsewhere in the Contract Documents.
5.2 The period covered by each Application for Payment shall be one calendar
month ending on the last day of the month, or as follows: ---NOT APPLICABLE---
5.3 Provided an Application for Payment is received by the Architect not later

Payment is received by the Architect after the application date fixed above,
payment should be made by the Owner not later than twenty calendar days after
the Architect receives the Application for Payment.
5.4 Each Application for Payment shall be based upon the Schedule of Values
submitted by the Contractor in accordance with the Contract Documents. The
Schedule of Values shall allocate the entire Contract Sum among the various
portions of the Work and be prepared in such form and supported by such data to
substantiate its accuracy as the Architect may require. This Schedule, unless
objected to by the Architect, shall be used as a basis for reviewing the
Contractor's Applications for Payment.
5.5 Applications for Payment shall indicate the percentage of completion of each
portion of the Work as of the end of the period covered by the Application for
Payment.
5.6 Subject to the provisions of the Contract Documents, the amount of each
progress payment shall be computed as follows:
5.6.1 Take that portion of the Contract Sum properly allocable to
completed Work as determined by multiplying the percentage
completion of each portion of the Work by the share of the total
Contract Sum allocated to that portion of the Work in the
Schedule of Values, less retainage of TEN percent (10%). Pending
final determination of cost to the Owner of changes in the Work,
amounts not in dispute may be included as provided in
Subparagraph 7.3.7 of the General Conditions even though the
Contract Sum has not yet been adjusted by Change Order;
5.6.2 Add that portion of the Contract Sum properly allocable to
materials and equipment delivered and suitably stored at the site
for subsequent incorporation in the completed construction (or,
if approved in advance by the Owner, suitably stored off the site
at a location agreed upon in writing), less retainage of TEN
percent (10%);
5.6.3 Subtract the aggregate of previous payments made by the Owner;
and
5.6.4 Subtract amounts, if any, for which the Architect has withheld
or nullified a Certificate for Payment as provided in Paragraph
9.5 of the General Conditions.
5.7 The progress payment amount determined in accordance with Paragraph 5.6
shall be further modified under the following circumstances:
5.7.1 Add, upon Substantial Completion of the Work, a sum sufficient
to increase the total payments to NINETY percent (90%) of the
Contract Sum, less such amounts as the Architect shall determine
for incomplete Work and unsettled claims; and
5.7.2 Add, if final completion of the Work is thereafter materially
delayed through no fault of the Contractor, any additional
amounts payable in accordance with Subparagraph 9.10.3 of the
General Conditions.
5.8 Reduction or limitation of retainage, if any, shall be as follows: (IF IT IS
INTENDED PRIOR TO SUBSTANTIAL COMPLETION OF THE ENTIRE WORK, TO REDUCE OR LIMIT
THE RETAINAGE RESULTING FROM THE PERCENTAGES INSERTED IN SUBPARAGRAPHS 5.6.1 AND
5.6.2 ABOVE, AND THIS IS NOT EXPLAINED ELSEWHERE IN THE CONTRACT DOCUMENTS,
INSERT HERE PROVISIONS FOR SUCH REDUCTION OR LIMITATION.)
Each such statement shall be for an amount equal to an estimate of the
Cost of the Work completed and materials delivered, less all previous
payments and less a retainage of 10% of that portion of the Work; when
the Work is 50% complete and the Owner approves, there shall be no
further retainage withheld on subsequent payments; and the balance shall
be paid when the Work is 100% complete and accepted by the Architect and
Owner.
ARTICLE 6
FINAL PAYMENT
Final payment, constituting the entire unpaid balance of the Contract Sum, shall
be made by the Owner to the Contractor when (1) the Contract has been fully
performed by the Contractor except for the Contractor's
responsibility to correct nonconforming Work as provided in Subparagraph 12.2.2
of the General Conditions and to satisfy other requirements, if any, which
necessarily survive final payment; and (2) a final Certificate for Payment has
been issued by the Architect; such final payment shall be made by the Owner not
more than 30 days after the issuance of the Architect's final Certificate for
Payment, or as follows:
