The engineer shall be <br /> notified immediately if any discrepancies are found. <br /> 2 The typical notes and details shall apply in all cases unless specifically detailed elsewhere. Where no detail is <br /> shown,the construction shall be as shown for other similar work and as required by the building code. <br /> 3 These calculations are limited to the structural members shown in these calculations only. <br /> 4 The contractor shall be responsible for compliance with local construction safety orders. Approval of shop <br /> drawings by the architect or structural engineer shall not be construed as accepting this responsibility. <br /> 5 All structural framing members shall be adequately shored and braced during erection and until full lateral and <br /> vertical support is provided by adjoining members. <br /> Structural Steel: <br /> 1 All structural steel code checks based on the AISC, 15th Edition per the TIA-222-H standard <br /> 2 All steel pipe to be per ASTM A53 GR. B(35 KSI), U.N.O. <br /> 3 All steel rectangular tubes(HSS)to be per ASTM A500 GR. B(46 KSI), U.N.O. <br /> 4 All other structural steel shapes&plates shall be per ASTM A36, U.N.O. <br /> 5 All bolts for steel-to-steel connections shall be per ASTM F3125 GR.A325 U.N.O. <br /> 6 All bolted connections shall be tightened per the"turn-of-nut"method as defined by AISC. <br /> 7 All welding shall be performed by certified welders in accordance with the latest edition of the American Welding <br /> Society(AWS) D1.1 <br /> 8 All steel surfaces shall be galvanized in accordance with ASTM A123 and ASTM F2329 standards,thoroughly <br /> coated with a zinc-rich primer, or otherwise protected as noted on the structural drawings. <br />
