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. <br /> FOOTINGS <br /> Wall footings are cast-in-place concrete with continuous reinforcing placed 3"clear of bottom and <br /> sides. Provide 40 diameter lap at all splices and full crossing lap at corners and intersections. <br /> Unless otherwise noted, wall footings are centered under walls and column footings under <br /> columns. Footing elevations shown on plan are to top of footing. Footings for walls, unless <br /> otherwise noted, shall be 10"thick with a minimum projection of 4" each side with 2-#4 <br /> continuous. <br />
