SCOPE
A.
It shall be understood that the requirements for seismic restraints are in addition to other
requirements as specified elsewhere for the support and attachment of equipment and
mechanical services, and for the vibration isolation of same equipment. Nothing on the
project drawings or specifications shall be interpreted as justification to waive the
requirements for seismic restraint as specified herein, shown on the drawings and required
by Code.
B.
The work under this section shall include furnishing all labor, materials, tools, appliances and
equipment, and performing all operations necessary for the complete execution of the
installation of seismic snubber restraint assemblies as shown, detailed and/or scheduled on
the drawings and/or specified in this section of the specifications.
C.
The materials and systems specified in this section shall be provided by the Contractor from
a single Seismic Snubber Restraint Materials Manufacturer to assure sole source
responsibility for the performance of the seismic restraints used.
D.
The seismic snubber restraint materials manufacturer shall be responsible for detailed design
for seismic supports, including calculation for size and attachment, signed and sealed by
registered State of Arizona Structural Engineer.
SUBMITTALS
A.
See Section 22 05 00 for general requirements for submittal materials. In addition to the
requirements contained in Section 22 05 00, provide submittal information for all products
and materials covered under this Section of the Specifications as listed herein.
B.
Furnish complete catalog data on all vibration isolators and restraints to be utilized for the
project in order to establish compliance with the plans and specifications and all code
requirements.
C.
Furnish complete shop drawing information including construction details for all support
points and anchor bolt requirements and locations; method of support for piping; method of
isolation for piping passing through the building structure; and location and arrangement of
seismic restraints.

SEISMIC RESTRAINT REQUIREMENTS
A.
The Contractor shall submit calculations prepared by a State of Arizona licensed Structural
Engineer to substantiate that all items of plumbing equipment, piping systems are properly
supported to resist earthquake forces as required herein.
B.
All items of plumbing equipment required for life safety shall be provided with seismic
restraints securely anchored to the building capable of resisting horizontal forces of 100% of
their weight and/or in accordance with IBC Requirements.
C.
All items of plumbing equipment, except as specified above, and all piping furnished and
installed under Division 22 shall be provided with seismic restraints securely anchored to the
building capable of resisting horizontal forces of 50% of their weight.
D.
Seismic restraint/snubber manufacturer shall be responsible for the structural design of
attachment hardware as required to attach seismic restraints/snubbers to both the equipment
and supporting structure on vibration isolated equipment, or to directly attach equipment to
the building structure for non-isolated equipment.
E.
The Contractor shall furnish a complete set of approved shop drawings of all mechanical and
electrical equipment which is to be restrained to the seismic restraint manufacturer, from
which the selection and design of seismic restraint devices and/or attachment hardware will
be completed. The shop drawings furnished shall include, at a minimum, basic equipment
layout, length and width dimensions, installed operating weights of the equipment to be
restrained and the distribution of weight at the restraint points.
