Openings in <br /> floor and roof not shown on structural drawings must be placed between structural members. <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 />
