Notify engineer if there are any deviations from the contract documents. Field <br /> verify dimensions and elevations prior to fabrication of structural members. <br /> TEMPORARY BRACING <br /> Provide temporary lateral support for all walls until walls are adequately braced by floor or roof <br /> structure. Provide required temporary bracing for structural steel until permanent bracing and <br /> walls are in place. <br /> STRUCTURAL STEEL <br /> All structural steel shall be designed, fabricated and erected according to the American Institute <br /> of Steel Construction(AI.S.C.)standard specifications. Structural steel supplier shall supply all <br /> cap plates, bearing assemblies, base plates,stiffeners, splices, connections and shall design <br /> same unless noted on drawings. All welding shall be done using the shielded arc process using <br /> E70 electrodes in accordance with the rules of the American Welding Society(A.W.S.)Structural <br /> Welding Code. All welders shall be certified using the rules of the American Welding Society. <br /> DIMENSION LUMBER <br /> Dimension lumber shall be No. 2 hem Fir or equal for joists, beams and headers. Wall studs shall <br /> be Stud Grade SPF or equal. Spacing of bridging for joists shall not exceed 8'-0". Wood lintels <br /> and headers shall have a full 1%"length of bearing at each end unless notes otherwise. Double <br /> all joists under parallel partitions. All beams and joists not bearing on supporting members shall <br /> be framed with"Simpson Strong-Tie'joist hangers or equal. Interior walls to have 2x4 studs at <br /> 16"on center. Exterior walls to have 2x6 studs at 16"on center. Wood joists shall bear the full <br /> width of supporting members(stud wall, beams, etc.)unless otherwise noted. <br />
