G. Tie securely or use splice devices to prevent displacement of splices during concrete placement. <br /> H. Support and wire together reinforcing to prevent displacement by construction loads and placing of concrete. <br /> Welding of cross bars is not permitted for assembly of reinforcement. On grade,supporting concrete brick may be <br /> used. Over formwork use approved bar chairs and spacers. <br /> I. Unless approved by the Architect,do not bend reinforcement after being partially embedded in hardened concrete. <br /> J. Show lap and spacing of reinforcing on shop drawings. <br /> K. Embed conduit and pipes after placing reinforcing steel in a manner that will not impair the strength of <br /> construction. Do not embed conduit and pipes larger in outside diameter than one-third thickness of slab, wall or <br /> beam,nor space closer than 3 diameters o.c.without approval of the Architect. For conduit or pipe which parallels <br /> principal reinforcement maintain 1-1/2"clear from reinforcing. <br /> 3.02 CONCRETE COVER <br /> A. For minimum concrete protection over reinforcement see ACI 318 Chapter 7 and as detailed on the Drawings. <br /> 3.03 FIELD QUALITY CONTROL <br /> A. Special Structural Testing and Inspection <br /> 1. Special Structural Testing and Inspection shall be performed by qualified parties as specified herein, and in <br /> accordance with the provision of Section 01410. <br /> 2. Personnel Qualifications: <br /> a. Special Inspector-Technical: Not used. <br /> b. Special Inspector-Structural: <br /> 1.) Structural I - Graduate civillstructural engineer, or other personnel acceptable to the Structural <br /> Engineer of Record (SER), with the experience in the design of structural systems of this type. <br /> Inspection shall be performed under the direct supervision of a registered civil/structural engineer. <br /> 2.) Structural H-Civil/structural engineer regularly engaged in the design of structural systems of this <br /> type,registered in the state in which the project is located. The registered engineer shall review and <br /> approve all inspection reports. <br /> 3. The Owner will employ a Special Inspector for the following inspections: <br /> a. Inspect reinforcement in all cast in place concrete, excluding slabs on grade,footings without transverse <br /> reinforcement,and topping slabs. Qualifications: Structural I. Verify the-following: <br /> 1.) Reinforcing bar grade. <br /> 2.) Reinforcing bars are free of oil,dirt,excessive rust,and damage. <br /> 3.) Reinforcing bars are adequately tied, chaired, and supported to prevent displacement during <br /> concrete placement. <br /> 4.) Proper clear distances between bars and to surfaces of concrete. <br /> 5.) Reinforcing bar size and placement. <br /> 6.) Bar laps for proper length and stagger. <br /> 7.) Bar bends for minimum diameter,slope and length. <br /> 8.) Mechanical splices are placed in accordance with the plans, specifications and reviewed shop <br /> drawings. <br /> END OF SECTION 03200 <br /> 03200-3 No. 99132-CP2 <br />
