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.] The following shall be submitted in accordance with Section 01 33 00 SUBMITTAL PROCEDURES: _{SD-02 Shop Drawings Storm windows} Submit drawings showing elevations of units, full-sized section, thicknesses and gages of material, fastenings, methods of anchorage, size and spacing of anchors, and locations of operating hardware.

PART 3 EXECUTION 3.1 PREPARATION NOTE: Insert additional subparagraphs on repairing, freeing stuck sash, weatherstripping, recalking, reputtying, sanding, and painting to suit the project. If other surfaces are to be painted, the reputtying, sanding, and painting should be specified in Section 09 90 00, PAINTS AND COATINGS. Clean, repair, and paint existing prime windows which are to receive storm windows before storm windows are installed. [Examination and repair of weatherstripping and sealant of the prime window is not required.] Clean glass [, wood,] and metal surfaces which will be between the storm and prime windows with appropriate detergents or cleaning agents. Leave free of dirt, streaks, fingerprints, and other soil. 3.2 INSTALLATION Install square, in true plane, level, plumb, in alignment with adjacent construction, and in accordance with manufacturer's printed instructions to ensure proper fit, sealing, and operation. 3.2.1 Sealants Make perimeter of storm windows weathertight, except at weep holes. Provide gaskets to separate new metal from existing metal. 3.2.2 Fastening Holes in the main frame shall be oversized to allow for expansion and contraction.
