1.2.4
Contractor Designed Bracing
**************************************************************************
NOTE: Retain this paragraph when the Contractor
will design the bracing. The designer will refer
and/or modify the listings above or will list below
the equipment and systems to receive seismic
bracing. Delete this paragraph when all bracing
details and locations are indicated on the drawings.
**************************************************************************
The Contractor shall design the bracing in accordance with TI 809-04 and
additional data furnished by the Contracting Officer. Resistance to
lateral forces induced by earthquakes shall be accomplished without
consideration of friction resulting from gravity loads. TI 809-04 uses
parameters for the building, not for the equipment in the building;
therefore, corresponding adjustments to the formulas shall be required.
Loadings determined using TI 809-04 are based on strength design;
therefore, AISC 325 Specifications shall be used for the design. The
bracing for the following mechanical equipment and systems shall be
developed by the Contractor: [_____].
1.2.5
Items Not Covered By This Section
1.2.5.1
Fire Protection Systems
Seismic protection of piping for fire protection systems shall be installed
as specified in Sections 13920 FIRE PUMPS, 13930A WET PIPE SPRINKLER
SYSTEM, FIRE PROTECTION, 13935A DRY PIPE SPRINKLER SYSTEM, FIRE PROTECTION,
13945A PREACTION AND DELUGE SPRINKLER SYSTEMS, FIRE PROTECTION, and 13955A
AQUEOUS FILM-FORMING FOAM (AFFF) FIRE PROTECTION SYSTEM.
1.2.5.2
Items Requiring No Seismic Restraints
**************************************************************************
NOTE: Retain only those items found in the project
for this list of pipes and ducts that do not require
