CONCRETE FORMWORK <br />Section 03100 <br />15-1207 <br />and no fractures, spalls or other surface defects larger than one -inch diameter; manufactured <br />by Burke, Dayton Superior, or accepted equal. <br />D. Spreaders: Metal (no wood permitted). <br />E. Form Release Agent: Colorless, nonstaining, free from Lass; chemically active agent that <br />shall not impair bonding of paint or other coatings intended for use. <br />F. Construction and Control Joint Material: <br />1. 26 ga. (minimum thickness) galvanized steel shapes to form tongue -and -groove joint. <br />2. 24 ga. Galvanized steel splice plates <br />3. 16 ga. Galvanized steel stakes <br />4. Acceptable manufacturers: <br />a. "Burke Joint Key" by Meadow Burke <br />b. "Pro -Key" by BoMetals, Inc. <br />C. Accepted equal <br />G. Expansion Joint Material: Preformed 1/2" fiber material with bituminous binder manufactured <br />for use as concrete expansion joint material. <br />H. Joints at Exposed Aggregate Surfaces: Capped divider strip; galvanized steel shape per <br />Article 2.01 F.1, with hard plastic retained cap. <br />Chamfer Strips: Rigid PVC: 3/4 x 3/4 inch size; maximum possible length; manufactured by <br />Burke, Greenstreak, Vulco or equal. <br />PART 3 - EXECUTION <br />3.01 WORKMANSHIP <br />A. Form to produce smooth concrete - straight, plumb and true to plane. Concrete out of line, <br />level or plumb will be rejected. <br />3.02 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 are warped or delaminated, or require more than <br />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 of exposed concrete surfaces, typical <br />unless noted otherwise on drawings. Form bevels, grooves and recesses to neat, straight <br />lines. Construct forms for easy removal without hammering, wedging or prying against <br />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 />3 <br />
