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 walis are adequately braced by floor or roof <br /> structure. <br /> FOOTINGS <br /> Wall footings are cast-in-place concrete with continuous reinforcing placed 3"clear of bottom and <br /> sides. Unless otherwise noted, wall footings are centered under walls and column footings under <br /> columns. Footings for walis, unless otherwise noted, shall be 10" thick with a minimum projection <br /> of 4" each side with 2 -#4 continuous. <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%2" 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. <br />
