<BRK/>
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” if the submittal item is not complex and can be reviewed through the Contractor’s 
Quality Control system.  Only add a “G” if the submittal is sufficiently important 
or complex in context of the project.<BRK/>
<BRK/>
For submittals requiring Government approval on 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 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,
