ON SITE VERIFICATION OF ALL DIMENSIONS AND CONDITIONS SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR AND SUB-CONTRACTORS. NOTES AND DIMENSIONS TAKES PRECEDENCE OVER SCALING OF THE DRAWING. EACH CONTRACTOR OR SUB-CONTRACTOR SHALL REPORT TO PROJECT OWNER AND DESIGNER ALL CONDITIONS WHICH PREVENT THE PROPER EXECUTION OF THEIR WORK. REFER TO ARCHITECTURAL DRAWINGS FOR ALL DIMENSIONS 2. NO DEVIATIONS FROM STRUCTURAL DETAILS SHALL BE MADE WITHOUT THE WRITTEN APPROVAL OF THE STRUCTURAL DESIGN ENGINEER. APPROVAL BY CITY INSPECTOR DOES NOT CONSTITUTE AUTHORITY TO DEVIATE FROM PLANS OR SPECIFICATIONS. 3. STRUCTURAL DESIGN DOES NOT CONSIDER EFFECTS OF MECHANICAL EQUIPMENT. 4. THE DESIGN ADEQUACY AND SAFETY OF ERECTION BRACING, SHORING, TEMPORARY SUPPORTS, ETC. IS SOLE RESPONSIBILITY OF THE CONTRACTOR AND HAS NOT BEEN CONSIDERED BY THE ENGINEER. THE CONTRACTOR IS RESPONSIBLE FOR THE STABILITY OF THE STRUCTURE PRIOR TO THE APPLICATION OF ALL SHEAR WALLS, ROOF AND FLOOR DIAPHRAGMS AND FINISH MATERIALS. STRUCTURAL DESIGN CRITERIA 1. SOIL BEARING CAPACITY ASSUMED TO BE 1,500 PSF 2. DESIGN VALUES ARE BASED OFF THE FOLLOWING CRITERIA: 2.1. RISK CATEGORY: II 2.2. GROUND FLOOR LIVE LOAD: 40 PSF 2.3. ROOF LIVE LOAD: 20 PSF 2.4. ROOF DEAD LOAD: 15 PSF (19 PSF WHERE SOLAR PANELS) 2.5. FLOOR LIVE LOAD: 30 PSF (BEDROOM AREA) 2.6. FLOOR LIVE LOAD: 40 PSF (OTHER AREAS) 2.7. FLOOR DEAD LOAD: 10 PSF 2.8. GROUND SNOW LOAD: 0 PSF 2.9. BASIC WIND SPEED: 95 MPH 2.10. EXPOSURE CATEGORY: B 2.11. ENCLOSURE CLASSIFICATION: ENCLOSED 2.12. SEISMIC SITE CLASS: D 2.13. SEISMIC DESIGN CATEGORY: D 2.14. RESPONSE MODIFICATION FACTOR: 6.5 2.15. SEISMIC DESIGN COEFFICIENTS: SDS=1.19, SD1=0.82 FOUNDATION 1. ANY VEGETATION AND/OR DEMOLITION DEBRIS SHALL BE REMOVED AND HAULED FROM THE PROPOSED GRADING AREAS PRIOR TO THE START OF GRADING OPERATIONS EXISTING VEGETATION SHALL NOT BE MIXED OR DISCED INTO THE SOILS 2. ANY REMOVED SOILS MAY BE REUSED AS COMPACTED FIL ONCE ANY DELETERIOUS MATERIAL OR OVERSIZED MATERIALS (IN EXCESS OF EIGHT INCHES) IS REMOVED. 3. GRADING SHALL EXTEND A MINIMUM OF SEVEN HORIZONTAL FEET OUTSIDE THE EDGES OF FOUNDATIONS OR EQUIDISTANT TO THE DEPTH OF FILL PLACED, WHICHEVER IS GREATER 4. DUE TO ELEVATED MOISTURE LEVELS IN THE SUBSURFACE SOILS, IT IS POSSIBLE THAT WET AND/OR YIELDING SOILS MAY BE ENCOUNTERED DURING SITE GRADING. AERATION OF WET SOILS AND STABILIZATION INCLUDING THE USE OF GEOTEXTILE FABRIC AND GRAVEL MAY BE REQUIRED BASED ON ACTUAL FIELD CONDITIONS DURING SITE GRADING CONCRETE 1. ALL CONCRETE SHALL HAVE A MINIMUM COMPRESSIVE STRENGTH (F'C) OF 2,500 PSI WITH TYPE V CEMENT AND MAXIMUM WATER CEMENT RATIO OF .45. NO SPECIAL INSPECTION REQUIRED IF CONCRETE TRUCK MIX TICKET IS PROVIDED. 2.
