required to pick up the comment immediately and resubmit unless requested by the Buyer.

However, if the Seller does re-submit the drawing(s) for other reasons, the comment shall be

picked up within the new revision.

Drawings and data that do not meet the minimum requirements of the Contract will be returned

marked “RETURNED FOR CORRECTION” (RFC), and will be regarded as not submitted. When

the drawings and data are returned marked “RFC”, the corrections shall be made as noted thereon

and as instructed by the Buyer, and the drawing shall be resubmitted for final approval as soon as

possible, but no later than ten (10) business days.

Additionally, drawings may receive a status of VOID if the drawings are no longer applicable to

the project due to changes in project scope.

When a drawing is revised and resubmitted, the Seller shall include an issue number and revision

description in the drawing revision block. All revisions pertaining to that particular drawing issue

shall be back circled or otherwise clearly noted on the drawing. Seller shall resubmit drawings

within ten (10) business days of receipt. Seller will be responsible for costs associated with

engineering and construction costs caused from drawings information that was changed and not

back circled and clearly identified as changed from the previous submittal.

reviewed.

Where comments are made that result in a Change to the Contract, the quantification and

qualification of the Change shall be recorded, in writing, in a form acceptable to Buyer and

submitted to Buyer within five (5) working days of receipt of the returned document.

No work shall be performed in connection with the fabrication or manufacture of Equipment and

materials until the drawings and data therein have been reviewed by the Buyer, except at the

Seller's own risk and responsibility. Work may proceed on Equipment and materials when the



drawings and data therefore have been returned marked APPROVED AS NOTED (AAN), or the

Buyer's transmittal letter indicates a status of APPROVED (APP) or FOR INFORMATION

ONLY (INF), provided the Work is performed in accordance with the Buyer's notations and the

Contract.

If changes are made to the Equipment at the Project Site, revised drawings indicating the changes

made shall be prepared by the Seller and submitted to the Buyer.
