SAMSON OCEANFRONT PARK <br />CITY OF SUNNY ISLES <br />TECHNICAL SPECIFICATIONS <br /> <br />CONCRETE REINFORCEMENT 03200-2 <br /> <br />1.09 INSPECTION COORDINATION: <br />A. The CONTRACTOR shall provide sufficient notice and opportunity to the Engineer to review the <br />placement of the reinforcing steel before the concrete is placed. The CONTRACTOR shall provide <br />access to the WORK for the ENGINEER as requested for inspection. The CONTRACTOR shall <br />provide 48 hours notice of its intention to begin new WORK activities. <br />PART 2 - PRODUCTS <br />2.01 REINFORCING BARS: <br />A. Metal reinforcement shall be deformed type bars conforming to ASTM A 615, Specifications for <br />Deformed and Plain Billet-Steel Bars for Concrete Reinforcement, Grade 60. Reinforcing steel shall <br />be fabricated for the shapes and dimensions indicated on the Drawings and in compliance with ACI <br />318. All bars shall be bent cold. <br />B. Replace all reinforcement with bends and kinks not shown on fabrication shop drawings. Remove <br />from job site all such reinforcing and replace with new fabricated steel. Field bending of <br />reinforcement at the work site is prohibited. <br />C. Welded wire fabric reinforcement shall conform to the requirements of ASTM A 185, and the details <br />indicated. Do not use fabric that has been rolled. Install flat sheets only. <br />D. Spiral reinforcement shall be cold-drawn steel wire conforming to the requirements of ASTM A 82. <br />2.02 ACCESSORIES: <br />A. All chairs and bolsters shall conform to ACI SP-66 and the CRSI Manual of Standard Practices and <br />shall have galvanized or plastic legs. <br />PART 3 - EXECUTION <br />3.01 PLACEMENT AND ANCHORAGE: <br />A. Bar supports shall be spaced in accordance with CRSI. <br />1. Reinforcement steel shall be supported by concrete, plastic or metal supports, spacers or metal <br />hangers that are strong and rigid enough to prevent any displacement of the reinforcement steel. <br />Where concrete is to be placed on the ground, supporting concrete blocks (or dobies) shall be <br />used in sufficient numbers to support the bars without settlement, but in no case shall such <br />support be continuous. Concrete blocks used to support reinforcement steel shall be tied to the <br />steel with wire ties that are embedded in the blocks. For concrete over formwork, the <br />CONTRACTOR shall provide concrete, metal, plastic, or other acceptable bar chairs and <br />spacers. <br />2. Limitations on the use of bar support materials shall be as follows. <br />a. Concrete Dobies: permitted at all locations except where architectural finish is required. <br />b. Wire Bar Supports: permitted only at slabs over dry areas, interior non-hydraulic wall <br />surfaces, and exterior wall surfaces. <br />c. Plastic Bar Supports: permitted at all locations except on grade. <br />B. Reinforcement shall be accurately placed in accordance with the Drawings and shall be adequately <br />secured in position with not less than 16-gauge annealed wire. The placement tolerances shall be in
