completion of the Work. Do not proceed until unsatisfactory conditions are corrected. 3.2 FORM CONSTRUCTION A. General: 1. Construct forms complying with ACI 347 to the exact sizes, shapes, lines, and dimensions shown, and as required to obtain accurate alignment, location, grades, and level and plumb work in the finished structure. 2. Provide for openings, offsets, key ways, recesses, moldings, reglets, chamfers, blocking, screeds, bulkheads, anchorages, inserts, and other features as required. B. Fabrication: 1. Fabricate forms for easy removal without hammering or prying against concrete surfaces. 2. Provide crush plates or wrecking plates where stripping may damage cast concrete surfaces. 3. Kerf wood inserts for forming key ways, reglets, recesses, and the like, to prevent swelling and assure ease of removal. 4. Provide top forms for inclined surfaces where so directed by the Architect. C. Forms for exposed concrete: 1. Drill forms to suite ties being used, and to prevent leakage of cement paste around tie holes. Do not splinter forms by driving ties through improperly prepared holes. 2. Provide sharp, clean comers at intersecting planes, without visible edges or offsets. Back the joints with extra studs or girts to maintain true, square intersections. 3. Use extra studs, wales, and bracing to prevent objectionable bowing of forms between studs, and to avoid bowed appearance in concrete. Do not use narrow strips of form material which will produce bow. D. Corner treatment: 1. Unless shown otherwise, form chamfers with 3/4" x 3/4" strips, accurately formed and surfaced to produce uniformly straight lines and tight edges. 2. Extend terminal edges to required limit, and miter the chamfer strips at changes in direction. E. Locate control joints as indicated on the Drawings and, where required but not shown on the Drawings, as approved by the Architect. F. Provisions for other trades: 03100-4
