35、SUBMITTAL PROCEDURES and edit the following list to reflect only the submittals required for the project. Submittals should be kept to the minimum required for adequate quality control.A “G” following a submittal item indicates that the submittal requires Government approval. Some submittals are alr

36、eady marked with a “G”. Only delete an existing “G” 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

37、Army projects, 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

38、 or other organization in the District Office); “AO“ for Area 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 seco
