1. GENERAL NOTES ON THIS DRAWING ARE APPLICABLE TO EACH

MECHANICAL DRAWING OF THIS SET. SEE EACH DRAWING FOR SPECIFIC

NOTES APPLICABLE TO THAT DRAWING.

0 DRAIN

EQUIPMENT, APPLIANCES AND SUPPORTS (INCLUDING ROOF CURBS AND ROOF RAILS) EXPOSED TO WIND SHALL BE DESIGNED AND INSTALLED TO RESIST THE WIND PRESSURES DETERMINED IN ACCORDANCE WITH THE INTERNATIONAL BUILDING CODE. WHERE SEISMIC RESTRAINT IS REQUIRED, THE MORE DEMANDING FORCE OF WIND AND SEISMIC MUST BE USED. SEE SEISMIC INFORMATION CONTAINED IN THE STRUCTURAL DRAWINGS FOR SITE SPECIFIC INFORMATION ON SEISMIC DESIGN CATEGORY, EQUIPMENT SCHEDULES AND DETAILS FOR SPECIFIC COMPONENT IMPORTANCE FACTOR DESIGNATIONS.

SEE COMPONENT/SYSTEM SCHEDULE BELOW FOR SPECIFIC COMPONENT IMPORTANCE FACTOR DESIGNATIONS AND SEISMIC DESIGN CRITERIA.

USE SEISMIC DESIGN CATEGORY TABLE BELOW TO DETERMINE SEISMIC RESTRAINT REQUIREMENTS FOR EACH ELECTRICAL COMPONENT/SYSTEM.

FOR ALL COMPONENTS/SYSTEMS REQUIRING SEISMIC RESTRAINT, THE COMPONENT SUPPORTS AND ATTACHEMENTS SHALL BE DESIGNED (CALCULATIONS AND INSTALLATION DETAILS) AND STAMPED BY A REGISTERED PROFESSIONAL ENGINEER (SEISMIC ENGINEER) THAT IS DIRECTLY EMPLOYED BY THE SEISMIC RESTRAINT MANUFACTURER (W-2 EMPLOYEE) WITH AT LEAST FIVE YEARS OF SEISMIC DESIGN EXPERIENCE, LICENSED IN THE STATE OF THE JOB LOCATION.

ALL RESTRAINING DEVICES SHALL HAVE A PREAPPROVAL NUMBER FROM CALIFORNIA OSHPD OR SOME OTHER RECOGNIZED GOVERNMENT AGENCY SHOWING

MAXIMUM RESTRAINT RATINGS.

WHERE SEISMIC RESTRAINT IS REQUIRED, HOUSEKEEPING PADS NEEDED FOR INSTALLATION OF EQUIPMENT UNDER THIS CONTRACT MUST BE DESIGNED AND STAMPED BY THE SEISMIC ENGINEER. DO NOT POUR ANY HOUSEKEEPING PADS PRIOR TO THE RECEIPT OF AN APPROVED SEISMIC SUBMITTAL FROM THE ENGINEER OF RECORD. ALL HOUSEKEEPING PADS DESIGNED AS EXPANSIONS TO EXISTING PADS OR INSTALLED ON TOP OF EXISTING CONCRETE FLOOR

SYSTEMS SHALL BE DOWELED INTO THE EXISTING SYSTEMS.
