<br />OTHER SIMILAR WORK SHALL APPLY.
<br />3.DETAILS IDENTIFIED AS TYPICAL, SHALL APPLY IN ESTIMATING AND CONSTRUCTION TO EVERY
<br />LIKE CONDITION WHETHER OR NOT THE REFERENCE IS REPEATED.
<br />4.THE STRUCTURAL DRAWINGS SHALL NOT BE SCALED. COORDINATE DIMENSIONS WITH
<br />MECHANICAL DRAWINGS.
<br />5.STANDARDS REFERENCED ON THE STRUCTURAL DRAWINGS REFER TO THE EDITION
<br />APPLICABLE UNDER THE CURRENT BUILDING CODE.
<br />6.THE RESPONSIBILITY FOR THE REVIEW AND COORDINATION OF DRAWINGS AND
<br />SPECIFICATIONS PRIOR TO THE START OF RELATED CONSTRUCTION SHALL BEAR ON THE
<br />CONTRACTOR. DISCREPANCIES THAT EXIST SHALL BE BROUGHT TO THE ATTENTION OF THE
<br />ENGINEER IN A TIMELY MANNER, PRIOR TO START OF RELATED CONSTRUCTION.
<br />7.WORK PERFORMED IN CONFLICT WITH THE STRUCTURAL DRAWINGS OR APPLICABLE BUILDING
<br />CODE REQUIREMENTS SHALL BE CORRECTED AT THE EXPENSE OF THE CONTRACTOR.
<br />8.DIMENSIONS, ELEVATIONS, AND SITE CONDITIONS SHALL BE VERIFIED BEFORE STARTING
<br />RELATED WORK AND THE ENGINEER NOTIFIED OF DISCREPANCIES IN A TIMELY MANNER.
<br />9.SITE CONDITIONS THAT ARE NOT REFLECTED ON THE STRUCTURAL DRAWINGS OR THAT
<br />DEVIATE FROM THE MAXIMUM OR MINIMUM DIMENSIONS INDICATED SHALL BE BROUGHT TO THE
<br />ATTENTION OF THE ENGINEER IN A TIMELY MANNER. SUCH CONDITIONS MAY INCLUDE

<br />PRIOR TO THE COMMENCEMENT OF WORK ON SUCH SYSTEM COMPONENT PER SEC 1704.4.
<br />B.TEMPORARY WORK AND SITE SAFETY
<br />1.THE STRUCTURAL DRAWINGS SHOW THE REQUIREMENTS FOR THE COMPLETED STRUCTURE
<br />ONLY. TEMPORARY WORKS REQUIRED TO COMPLETE THE CONSTRUCTION PROCESS SHALL BE
<br />THE RESPONSIBILITY OF THE CONTRACTOR. THE STRUCTURAL ENGINEER SHALL NOT BE
<br />RESPONSIBLE FOR THE DESIGN OR FIELD VERIFICATION OF TEMPORARY AND ANCILLARY
<br />WORK.
<br />2.THE RESPONSIBILITY FOR SAFETY IN AND AROUND THE JOBSITE SHALL BEAR ON THE
<br />CONTRACTOR. PROPER AND SAFE METHODS OF CONSTRUCTION SHALL BE EMPLOYED AT ALL
<br />TIMES INCLUDING THE STABILIZING OF INCOMPLETE STRUCTURES, FORMWORK, SHORING,
<br />RESHORING, FALSEWORK, PLATFORMS, SCAFFOLDING, BARRIERS, WALKWAYS, ETC. AND
<br />INCLUDING CONTROL OF THE INTENSITY, DURATION AND LOCATION OF CONSTRUCTION LOADS.
<br />3.THE CONSTRUCTION SHALL NOT RESTRICT A FIVE-FOOT CLEAR AND UNOBSTRUCTED ACCESS
<br />TO ANY WATER OR POWER DISTRIBUTION FACILITIES (POWER POLES, PULL-BOXES,
<br />TRANSFORMERS, VAULTS, PUMPS, VALVES, METERS, APPURTENANCES, ETC.) OR TO THE
<br />LOCATION OF THE HOOKUP. THE CONSTRUCTION SHALL NOT BE WITHIN TEN FEET OF ANY
<br />POWER LINES-WHETHER OR NOT THE LINES ARE LOCATED ON THE PROPERTY. FAILURE TO
<br />COMPLY MAY CAUSE DELAYS AND/OR ADDITIONAL EXPENSES.
<br />C.STRUCTURAL STEEL
<br />1.STRUCTURAL STEEL WORK SHALL BE PERFORMED IN ACCORDANCE WITH CHAPTER 22 OF THE
<br />BUILDING CODE, AISC 360 "SPECIFICATION FOR STRUCTURAL STEEL BUILDINGS" AND AISC 303
<br />"CODE OF STANDARD PRACTICE FOR STEEL BUILDINGS AND BRIDGES".
<br />2.STRUCTURAL STEEL STRENGTHS AND GRADES SHALL BE AS FOLLOWS, U.O.N.:
<br />DESCRIPTION YIELD ASTM FY,KSI GRADE
<br />ANGLES, CHANNELS
<br />& OTHER SHAPES 36ksi A36
<br />STRUCTURAL PIPE SECTIONS 35ksi A53, GR B
<br />3.EXTERIOR STRUCTURAL STEEL PERMANENTLY EXPOSED TO THE WEATHER SHALL BE HOT-DIP
<br />GALVANIZED AFTER FABRICATION. ZINC COATING SHALL CONFORM TO ASTM A 123 (G60, U.O.N.).

<br />1.UNLESS OTHERWISE NOTED, FRAMING LUMBER SHALL BE DOUGLAS FIR
<br />LARCH, GRADE-MARKED BY THE WCLIB OR WWPA AS FOLLOWS:
<br />BLOCKING NO.2
<br />STRUCTURAL USE PANELS APA RATED
<br />2.NAILS SHALL BE COMMON WIRE. NAILING SHALL COMPLY WITH TABLE
<br />2304.9.1 OF THE BUILDING CODE. NAILS EXPOSED TO WEATHER SHALL BE
<br />HOT-DIP GALVANIZED, U.O.N.
<br />3.FRAMING ANCHORS, POST CAPS, COLUMN BASES, HANGERS, ETC. SHALL
<br />BE MANUFACTURED BY SIMPSON, OR APPROVED EQUAL.
<br />4.SHEATHING SHALL BE APA-RATED STRUCTURAL USE PANELS CONFORMING
<br />TO PRODUCT STANDARD PS 1 FOR PLYWOOD OR PS 2 FOR ORIENTED
<br />STRAND BOARD (OSB).
<br />5.BOLT HOLES IN WOOD SHALL BE DRILLED 1/32" TO 1/16" IN DIAMETER
<br />LARGER THAN THE NOMINAL BOLT SIZE. RETIGHTEN ALL NUTS PRIOR TO
<br />CLOSING IN.
<br />6.BOLTS SHALL HAVE A 7 DIA. MIN. END DISTANCE AND A 4 DIA. EDGE
<br />DISTANCE, U.O.N.
<br />7.STANDARD CUT WASHERS SHALL BE USED UNDER ALL BOLT HEADS AND
<br />NUTS AGAINST WOOD. USE HEAVY PLATE OR MALLEABLE IRON WASHERS
<br />FOR ALL BOLTS DESIGNED TO ACT IN TENSION, SUCH AS LEDGERS AND
<br />HOLD DOWN ANCHORS.
<br />8.LAG BOLTS SHALL BE PRE-DRILLED TO A DIAMETER OF 60 PERCENT OF THE
<br />SHANK DIAMETER. THE BOLT SHALL BE TURNED BY A WRENCH AND NOT
<br />HAMMERED.
<br />E. SHEET METAL SCREWS
<br />1.SCREWS SHALL BE ITW BUILDEX "TEKS" PER ICC ESR-1976 AND SHALL BE
<br />INSTALLED PER THE MANUFACTURER'S RECOMMENDATIONS.
<br />2.SCREWS TO CONFORM TO THE REQUIREMENTS OF ASTM C1513.
<br />3.UNLESS OTHERWISE NOTED, SCREWS SHALL CONFORM TO THE
<br />FOLLOWING REQUIREMENTS:
<br />A. SIZE: #12
<br />B. ZINC-PLATED HARDENED STEEL
<br />C. SELF-TAPPING
<br />D. HEX-HEAD
<br />4.DURING INSTALLATION OF SCREWS, THE SCREW SHALL PENETRATE BOTH
<br />PLIES OF MATERIAL TO BE ATTACHED, WITH A MINIMUM OF 3 THREADS OF
<br />SCREW TIP EXPOSED.
<br />5.SCREWS SHALL BE TIGHTENED IN SUCH A MANNER THAT THE
<br />WASHER-FACE OF SCREW HEAD IS FLUSH WITH ADJACENT PLY, AND PLIES
<br />OF MATERIAL TO BE FASTENED ARE DRAWN TOGETHER SNUGLY.
<br />6.SCREWS SHALL MEET THE FOLLOWING MINIMUM STRUCTURAL
<br />REQUIREMENTS:
<br />F. LAG SCREW LEAD HOLES AND INSERTION
<br />1.PRE-BORED HOLES FOR LAG SCREWS SHOULD HAVE THE SAME DIAMETER
<br />AS THE SHANK FOR THE LENGTH OF THE SHANK AND FROM 60 PERCENT TO
<br />75 PERCENT OF THE SHANK DIAMETER FOR THE THREADED PORTION. THE
<br />HIGHER PERCENTAGE APPLIES TO LAG SCREWS OF LARGER DIAMETERS.
<br />EXTRA LONG LAG SCREWS MAY REQUIRE SLIGHTLY LARGER LEAD HOLES
<br />TO PREVENT SPLITTING AND TO FACILITATE TURNING.
<br />2.LAG SCREWS SHOULD BE INSERTED BY TURNING WITH A WRENCH.
<br />DRIVING WITH A HAMMER TEARS THE WOOD FIBERS AND INJURES THE
<br />SCREW THREAD SERIOUSLY REDUCING THE LOAD CARRYING CAPACITY OF
<br />THE SCREW. SOAP OR OTHER LUBRICANTS MAY BE USED TO FACILITATE
<br />INSERTION OF LAG SCREWS.
