Only add a “G” if the submittal is sufficiently important or complex in context of the project.For submittals requiring Government approval on Army pr

19、ojects, a code of up to three characters within the submittal tags may be used following the “G“ designation to indicate the approving authority. Codes for Army projects using the Resident Management System (RMS) are: “AE“ for Architect-Engineer; “DO“ for District Office (Engineering Division or oth

20、er organization in the District Office); “AO“ for Area Office; “RO“ for Resident Office; and “PO“ for Project Office.
