SITE CONCRETE <br />Section 03000 <br />15-1207 <br />frames and covers that are located within the concrete placements. <br />1. The bars shall be placed so that there will be a minimum of 1 '/2" clearance and a <br />maximum of 3" clearance. The reinforcing steel shall be placed mid -depth of concrete <br />slab. <br />E. At all right angles or intersections of concrete walks, additional 2'x2'#5, 90 degree bars shall <br />be added at all inside comers for additional crack control. The bars shall be placed 2" from <br />concrete forms and supports at mid -depth of slab. <br />3.02 PROTECTION <br />A. Protect work and materials of this Section prior to and during installation, and protect the <br />installed work and materials of other trades. <br />B. In the event of damage, make all repairs and replacements necessary to the approval of the <br />Architect at no additional cost to the Omer. <br />3.03 CLEANING <br />A. Reinforcement and all other embedded items at time of placing concrete to be free of rust, dirt <br />oil or any other coatings that would impair bond to concrete. <br />B. Remove all wood chips, sawdust, dirt, loose concrete and other debris just before concrete is <br />to be poured. Use compressed air for inaccessible areas. Remove all standing water from <br />excavations. <br />3.04 FORMING <br />A. Form material shall be straight, true, sound and able to withstand deformation due to loading <br />and effects of moist curing. Materials which have warped or delaminated, or require more <br />than minor patching of contact surfaces, shall not be reused. <br />B. Build forms to shapes, lines, grades and dimensions indicated. Construct form work to <br />maintain tolerances required by ACI 301. Forms shall be substantial, tight to prevent leakage <br />of concrete, and properly braced and tied together to maintain position and shape. Butt joints <br />tightly and locate on solid backing. Chamfer corners where indicated. Form bevels, grooves <br />and recesses to neat, straight lines. Construct forms for easy removal without hammering, <br />wedging or prying against concrete. <br />C. Space clamps, ties, hangers and other form accessories so that working capacities are not <br />exceeded by loads imposed from concrete or concreting operations. <br />D. Build openings into vertical forms at regular intervals if necessary to facilitate concrete <br />placement, and at bottoms of forms to permit cleaning and inspection. <br />E. Build in securely braced temporary bulkheads, keyed as required, at planned locations of <br />construction joints. <br />F. Slope tie -wires downward to outside of wall. <br />G. Brace, anchor and support all cast -in items to prevent displacement or distortion. <br />7 <br />
