23、g list to reflect only the submittals required for the project. Keep submittals to the minimum required for adequate quality control.A “G” following a submittal item indicates that the submittal requires Government approval. Some submittals are already marked with a “G”. Only delete an existing “G”
24、if the submittal item is not complex and can be reviewed through the Contractors Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in context of the project.For submittals requiring Government approval on Army projects, use a code of up to three characters
25、within the submittal tags 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 other organization in the District Office); “AO“ for Are
26、a Office; “RO“ for Resident Office; and “PO“ for Project Office. Codes following the “G“ typically are not used for Navy, Air Force, and NASA projects.Choose the first bracketed item for Navy, Air Force and NASA projects, or choose the second bracketed item for Army projects.*Government approval is
