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 submi

9、ttals 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 Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in context of the project.For submittals requiring Government

10、 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 (Enginee

11、ring Division or other organization in the District Office); “AO“ for Area Office; “RO“ for Resident Office; and “PO“ for Project Office.

30、ork.1.5.2 DrawingsBecause of the small scale of the drawings, it is not possible to indicate all offsets, fittings, and accessories that may be required. The Contractor shall carefully investigate the plumbing, fire protection, electrical, structural and finish conditions that would affect the work

31、to be performed and shall arrange such work accordingly, furnishing required offsets, fittings, and accessories to meet such conditions. The Contractor shall submit detailed drawings consisting of:a. Equipment layouts which identify assembly and installation details.b. Plans and elevations which ide

32、ntify clearances required for maintenance and operation.c. Wiring diagrams which identify each component individually and all interconnected or interlocked relationships between components.d. Foundation drawings, bolt-setting information, and foundation bolts prior to concrete foundation constructio

33、n for all equipment indicated or required to have concrete foundations.e. Details, if piping and equipment are to be supported other than as indicated, which include loadings and type of frames, brackets, stanchions, or other supports.*NOTE: Warranties on Navy construction: Warranties for equipment,

34、 materials, or design furnished, or workmanship performed by the Contractor or any subcontractor or supplier, has a duration of one year from the date of final acceptance of the work. An exception is in normal commercial practice longer warranty period for particular construction are given.An exampl

35、e of a typically longer duration period is the warranty for the chiller refrigeration compressor, is typically good for five years. The Contractor submits to the Contracting Officer all applicable warranties signed and official prior to project closeout.If a longer than one year warranty duration is

36、 desired, it is recommended that the specifier/designer survey the chiller market to determine if the chiller industry normally provides a longer warranty for all of the subject chiller or for any major components.SECTION 23 64 00 Page 8Provided by IHSNot for Resale-,-,-A warranty duration of longer

37、 than a year, and not covered normally by the industry, requires a Level III Contracting Officers written determination documenting that the extra warranty protection is needed.*1.6 WarrantyIn addition to the warranty requirements specification in Division 00, Contract Requirements, the following ma
