' PART 3 - EXECUTION <br /> 3.01 PLACING REINFORCEMENT <br /> A. Support and wire all reinforcing bars together to prevent displacement by construction <br /> loads or the placing of concrete. Methods and details of placing, and concrete protection <br /> required, shall comply with Chapter 8 of CRSI "Manual of Practice". <br /> 3.02 JOINTS AND EMBEDDED ITEMS <br /> A. Construction Joints: <br /> 1. See Sections 02622, 02631, and City Standards. <br /> 2. Continue all reinforcing steel and mesh across crack control joints. Provide <br /> ' longitudinal keys at least 1-1/2 inches deep in all joints in walls. <br /> 3. Clean the surface of the concrete at all joints and remove all latency. <br /> 4. When required, obtain bond by roughening the surface of the concrete to the <br /> satisfaction of the Owner's Representative. <br /> B. Expansion Joints: <br /> 1. Install expansion joint fillers. <br /> 2. Where called for on drawings, load transfer dowels shall consist of plain bars with <br /> one half coated with an approved antibond coating. The coated half shall be <br /> sleeved. No other reinforcement or metal shall extend continuously through the <br /> joint. <br /> C. Other Embedded Items: <br /> 1. Prior to concreting, place all required sleeves, inserts, anchors, and embedded <br /> items. <br /> 2. Give all trades, whose work is related to the concrete or must be supported by it, <br /> ample notice and opportunity to introduce embedded items before concrete is <br /> placed. <br /> 3. Position expansion joint material and embedded items accurately and support <br /> them against displacement. Fill voids in sleeves, inserts, and anchor slots <br /> temporarily with readily removable material to prevent the entry of concrete. <br /> 3.03 PREPARATION OF FORM SURFACES <br /> ' A. Ensure that forms are clean and free of ice or water. <br /> B. Seal plywood with coating material to minimize absorption of moisture from the concrete. <br /> 3.04 PLACING OF CONCRETE <br /> A. Preparations before Placing: <br /> 1. Remove hardened concrete and foreign materials from inner surfaces of <br /> conveying equipment. <br /> 2. Check formwork for completion, check position and securement of reinforcement, <br /> ' expansion joint material, anchors and other embedded items and obtain approval <br /> on entire preparation. <br /> 3. Remove ice and excess water and sprinkle semi porous sub-grades sufficiently <br /> to eliminate suction. <br /> ' 4. Do not place concrete on frozen ground. <br /> 5. Do not place concrete during rain, sleet or snow unless protection is provided. <br /> 6. In cold weather, or very hot weather, check to see that concrete temperature <br /> meets the requirements of Section 10.8 and 10.9 of ASTM C94. <br /> 7. Provide temporary openings at the base of column forms and wall forms and at <br /> other points where necessary to facilitate cleaning and observation immediately <br /> before concrete is placed. <br /> ' 8. Place suitable moldings or chamfer strips in the corners of column, beam and <br /> wall forms where the concrete will be exposed to view. <br /> B. Depositing: <br /> 1. Handle concrete from the mixer to the place of final deposit as rapidly as <br /> practicable by methods which will prevent separation or loss of ingredients and <br /> assure that the required quality of the concrete is obtained. <br /> ' SPORTSMAN'S WAREHOUSE 02626-3 <br />
