Bearing value to be verified by a geotechnical engineer. COORDINATION -ARCHITECTURAL, MECHANICAL AND ELECTRICAL ITEMS Location, dimensions and details of recesses, depressions, openings and equipment supports shall be verified by reference to architectural, mechanical and electrical drawings. TEMPORARY BRACING Provide temporary lateral support for all walls until walis are adequately braced by floor or roof structure. Provide required temporary bracing for structural steel until permanent bracing and walls are in place. FOOTINGS Wall footings are cast-in-place concrete with continuous reinforcing placed 3" clear of bottom and sides. Provide 40 diameter lap at all splices and full crossing lap at corners and intersections. Unless otherwise noted,wall footings are centered under walls and column footings under columns. Footings for walls, unless otherwise noted, shall be 10"thick with a minimum projection of 4" each side with 2-#4 continuous.
