3.2 A dry pipe system shall serve a dry wall hydrant on each floor.
3.3 Provide wet exterior wall hydrants to be used for minimal irrigation,
clean walks, etc.
Locate them a maximum of 60 m (200 feet) apart,
with a minimum of one wall hydrant on each exterior wall.
4. STORM DRAINAGE SYSTEM
4.1 Base storm frequency on local code.
4.2 Use trench drains and/or type "Y" floor drains.
5. RISER DIAGRAMS
5.1 Provide riser diagram for storm drainage system.
5.2 Riser diagram may be shown flat, or in isometric projection.
Show
story heights, and size of all horizontal and vertical piping.
Show
system complete and continuous.
6. SEISMIC REQUIREMENTS
6.1 GENERAL:
A. Earthquake-resistive design shall comply with the requirements of
Design and Construction Procedures, " Natural Disasters Non-
Structural Resistive Design"; the latest edition of "Seismic Design
Requirements"; and the Uniform Building Code (UBC) published by
International Conference of Building Officials (ICBO).
B. Equipment and piping shall be braced in accordance with the most
current edition of Seismic Restraint Manual Guidelines for Mechanical
Systems (SMACNA) and National Uniform Seismic Installation Guidelines
(NUSIG).
C. Unless otherwise shown by SMACNA or NUSIG, provide required details
and structural calculations to completely address seismic bracing
requirements.
See paragraph 6.4 "CALCULATIONS".
D. SMACNA does not cover all conditions such as, providing bracing
details for seismic restraints of equipment or details of flexible
joints when crossing seismic or expansion joints, or bracing of in-
line equipment, etc.
E. Coordinate earthquake-resistive design with the project Professional
Structural Engineer for appropriateness and soundness.
F. Both, SMACNA and NUSIG list conditions under which seismic bracing
may be omitted.
However, a design professional may revoke these
omissions on an individual project basis.
6.2 CONFORMANCE WITH SMACNA:
A. Requires a design professional to develop a Seismic Hazard Level
(SHL) for a specific project for use of its manual.
The SHL is
derived from a combination of factors such as applicable building
codes, seismic zones, and importance factors into a single system for
