20、TY CONTROL PROGRAM. The specification writer or design engineer must indicate how much quality control of welding is needed for each project and who is to be responsible; i.e., primarily the Contractor or the Government.In many cases a project may not require 100 percent testing of welds by NDE meth

21、ods. The designer must determine the required methods and the extent of inspection and testing, and must indicate the extent in this or other sections of the project specifications or on the project drawings by notes, NDE symbols, or other means. The referenced applicable publications will be used f

22、or guidance in determining inspection and testing requirements.The specifications or drawings must clearly indicate which joints require 100 percent NDE inspection, which joints require random NDE inspection, and which NDE methods are to be employed for each joint. For random inspection, the drawing

23、s must indicate the location, number of joints, and minimum increment length of weld that will be NDE inspection without predisclosing the exact spots to be examined. Joints not indicated to be tested by NDE methods shall be subject to visual inspection only. In cases where the nature of the welding

24、 is such as to require visual inspection only, the requirements for NDE should be deleted from these paragraphs and SECTION 40 05 13.96 Page 5Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-from paragraph Inspection and NDE Personnel.*Quality of all

25、joint preparation, welding, and examination is the Contractors responsibility for. Clearly identify and record all materials used in the welding operations. The inspection and testing defined in this specification are minimum requirements. Additional inspection and testing shall be the responsibilit

26、y of the Contractor when it is deemed necessary to achieve the quality required.1.4 SUBMITTALS*NOTE: Review submittal description (SD) definitions in Section 01 33 00 SUBMITTAL PROCEDURES and edit the following list to reflect only the submittals required for the project. Submittals should be kept t

27、o 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 Contractors

28、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 a

29、pproving 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 fo

30、llowing 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 “

31、G“ designation are for Contractor Quality Control approval.information only. When used, a designation following the “G“ designation identifies the office that will review the submittal for the Government.
