UFC 3-450-01, UNIFIED FACILITIES CRITERIA (UFC): NOISE AND VIBRATION CONTROL (15-MAY-2003) [SUPERSEDES TM 5-805-4 & AIRFORCE AFJMAN 32-1090]., This UFC supersedes TM 5-805-4, dated 26 May 1995. This manual provides qualified designers the criteria and guidance required for design and construction of those features related to noise and vibration control of mechanical equipment systems most commonly encountered in military facilities. These criteria apply to all new construction and to major alteration of existing structures. US military facilities that require higher standards because of special functions or missions are not covered in this manual; criteria for these and other exceptions are normally contained in a design directive. If standards given in this manual and its referenced documents do not provide all the needs of a project, recognized construction practices and design standards can be used. Noise level estimates have been derived for various types of mechanical equipment, and in some cases graded for power or speed variations of the noise-producing machines. The noise level estimates quoted in the manual are typically a few decibels above the average. Therefore, these noise level estimates should result in noise control designs that will adequately “protect” approximately 80 to 90 percent of all equipment. It is uneconomical to design mechanical equipment spaces to protect against the noise of all the noisiest possible equipment; such overdesign would require thicker and heavier walls and floors than required by most of the equipment. The noise estimates and the noise control designs presented may be used with reasonable confidence for most general purposes. Data and recommendations are given for mechanical equipment installations on-grade and in upper-floor locations of steel and concrete buildings. Though they can also be applied to equipment located in upper floors of buildings on allwood construction, the low mass of such structures for the support of heavy equipment will yield higher noise and vibration levels than would normally be desired. Data and recommendations are also given for the analysis of noise in the surrounding neighborhood caused by mechanical equipment, such as cooling towers. On-site power plants driven by reciprocating and gas turbine engines have specific sound and vibration problems, which are considered separately in the manual TM 5-805-9/AFM 88-20.
