VIBRATION AND SEISMIC CONTROLS FOR PLUMBING PIPING AND EQUIPMENT
1.01 DESCRIPTION OF WORK:
A. Extent of vibration control work required by this Section is indicated on drawings and
schedules, and/or specified in other Division 22 sections.
1. All plumbing equipment and piping as noted or in the specification shall be
mounted on vibration isolators to prevent the transmission of vibration and
mechanically transmitted sound to the building structure. Vibration isolators shall
be selected in accordance with the weight distribution so as to produce reasonably
uniform deflection.
2. All such systems must be installed in strict accordance with component
manufacturer’s and building construction standards. Whenever a conflict occurs
between the manufacturer's or construction standards, the most stringent shall
apply.
3. Any variance from or non-compliance with these specification requirements shall
be corrected by the contractor in an approved manner.
B. The work of this Section includes, but is not limited to, the following:
1. Vibration isolation for all plumbing systems/equipment, including, but not limited
to, the following: Pumps (all types)
2. Vibration isolation for piping.
3. Equipment isolation bases.
4. Flexible piping connections.
C. Vibration control products furnished as an integral part of factory-fabricated equipment
shall be accepted only if they fully comply with the requirements of this Section.
D. For additional and supplemental requirements, refer to other Division 22 sections for
equipment foundations; hangers; sealants; gaskets; requirements of electrical connections
to equipment isolated on vibration control products;
1.02 QUALITY ASSURANCE:
A. Manufacturer's Qualifications: Firms regularly engaged in manufacture of vibration
control products, of types, sizes, and capacities required, whose products have been in
satisfactory use in similar service for not less than five years.
1.03 SUBMITTALS:
1. Except as otherwise indicated, vibration control products shall be obtained from a
single manufacturer and shall be certified by the manufacturer.
