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
