In the event that it is necessary to require any material change in the submitted plans prior to approval, the Commissioner's representative will outline the required revisions by letter to the engineer and the plans shall be revised as required for approval. Copies of the original submission will be returned to the engineer for revision if deemed necessary. Otherwise, revision may be made by revised plan sheets and addenda to the specifications. In the event that it becomes necessary to make any material change, including equipment substitutions or the provision of "equals," in the approved plans and specifications, subsequent to the date of approval and to the placing of official stamp on such approved plans and specifications, revised plans and specifications in quadruplicate, or duplicate on a project of sufficiently limited scope, together with a statement for the reason for the changes shall be submitted to the Commissioner's representative for review and comment or approval. No part of the work affected by the change or changes shall be started or completed until the Commissioner's representative has given his approval in writing; except that emergency changes which are required as construction proceeds may be made upon verbal approval from the Commissioner's representative, provided that such changes are reflected in as-built plans and specifications which are submitted in the appropriate number of copies at the conclusion of project construction.
