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 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. 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, 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 required for submittals with a "G" designation; submittals not having a "G" designation are [for Contractor Quality Control approval.][for information only. When used, a designation following the "G" designation identifies the office that will review the submittal for the Government.] Submit the following in accordance with Section 01 33 00 SUBMITTAL PROCEDURES: _{SD-02 Shop Drawings} Submit _{Installation Drawings} in accordance with paragraph entitled, "General Requirements," of this section. _{SD-03 Product Data} Submit manufacturer's catalog data for the following items: _{Borosilicate Glass Materials High-Silicon Cast Iron Material Polyethylene Material Polypropylene Material Polyvinylchloride Material SD-06 Test Reports} Submit _{Test Reports} in accordance with paragraph entitled, "Installation and Testing," of this section. _{SD-07 Certificates} Submit _{Listing of Product Installations} in accordance with paragraph entitled, "Installation and Testing," of this section.
