CAST -IN-PLACE CONCRETE <br />Section 03300 <br />15-1207 <br />8. Apply specified tape at all other conditions not indicated above as recommended by the <br />manufacturer. <br />3.03 PLACING OF CONCRETE <br />A. Adjacent finish surfaces shall be protected at all times during the concrete pour and finishing. <br />Verify that all formwork is tight and leak -proof before concrete is poured. Finish work <br />defaced during the concrete pour and finishing shall be replaced at no extra cost to the <br />owner. <br />B. Transport concrete from mixer to place of final deposit as rapidly as practicable by methods <br />which will prevent separation or loss of ingredients. Deposit as close as practicable in final <br />position to avoid re -handling or flowing. Partially hardened concrete must not be deposited in <br />work. Concrete shall not be wheeled directly over the top of reinforcing steel. <br />C. Placing: Once started, continue concrete pour continuously until section is complete between <br />predetermined construction joints. Prevent splashing of concrete onto adjacent forms or <br />reinforcement and remove such accumulation of hardened or partially hardened concrete <br />from forms or reinforcement before work proceeds in that area. Free fall of concrete shall not <br />to exceed 4'-0" in height. If necessary, provide lower openings in forms to inject concrete and <br />to reduce fall height. <br />D. Remove form spreaders as placing of concrete progresses. <br />E. Place footings as monolithic and in one continuous pour. <br />F. Keep excavations free of standing water. <br />G. Compacting: All concrete shall be compacted by mechanical vibrators. Concrete shall be <br />thoroughly worked around reinforcement and embedded fixtures and into corners of forms. <br />Vibrating shall not be applied to concrete which has already begun to initially set nor shall it <br />be continued so long as to cause segregation of materials. <br />H. Grout under column bearing plates: Dry pack with specified Non -shrink Grout, as <br />recommended by manufacturer. Use as little water as practicable. Ram grout solid into <br />place. <br />Concrete slabs (Interior and Exterior): <br />All slabs shall be formed and finished to required line and grades. Slabs on grade shall <br />be true and flat with a maximum tolerance of 1/8" in 10' for flatness. Interior slabs shall <br />also be level. Slabs which are not flat and are outside of the maximum specified <br />tolerances shall be brought into compliance by the Contractor at no additional expense <br />to the Owner. <br />2. Thoroughly water and soak the exterior slab subgrade at least one day prior to the <br />concrete pour and immediately before the concrete pour. Provide damming as required <br />to keep water within the formed area and to allow for proper saturation of the subgrade. <br />3. Slope slab to floor drain where indicated on plans. <br />Placing in hot weather: Comply with ACI 305R-99. Concrete shall not exceed 85 degrees F <br />7 <br />
