Where resilient or elastomeric <br />sheet flashing, or bituminous membranes are terminated in reglets, provide <br />reglets of not less than 26 gauge (0.55mm) galvanized sheet metal. Fill reglet or <br />cover face opening to prevent intrusion of concrete or debris. <br />K.Coordinate with materials as specified in Section 032000/Concrete <br />Reinforcement and Embedded Assemblies. <br />PART 3 - EXECUTION <br />3.1 FORMWORK <br />A.General: <br />1.Inspect areas to receive formwork. <br />a)Immediately notify the Owner’s Testing Agency and Design <br />Professionals in writing of conditions that will adversely affect the <br />Work. <br />2.Construct forms to sizes, shapes, lines, and dimensions shown on <br />Contract Documents, and to obtain accurate alignment, location, grades, <br />level and plumb work in finished structures. <br />3.Provide formwork sufficiently tight to prevent leakage of cement paste <br />during concrete placement. Solidly butt joints and provide backup material <br />at joints as required to prevent leakage and fins, and to maintain <br />alignment. <br />4.Provide for openings, offsets, sinkages, keyways, recesses, moldings, <br />rustications, reglets, drips, bevels, chamfers, blocking, screeds, <br />bulkheads, anchorages and inserts and other features required in the <br />Work. <br />5.Comply with shop drawings, ACI 301, 318, 347 and Contract Documents. <br />6.Maintain formwork and finished work construction tolerances complying <br />with ACI 301 and 117. <br />7.Provide shore and struts with positive means of adjustment capable of <br />taking up formwork settlement during concrete placing operations, using <br />wedges or jacks or a combination thereof. <br />8.Erect forms for easy removal without hammering or prying against <br />concrete surfaces. <br />9.Provide crush plates or wrecking plates where stripping may damage cast <br />concrete surfaces. <br />10.Provide top forms for inclined surfaces where slope is too steep to place <br />concrete with bottom forms only. <br />11.Kerf wood inserts for forming keyways, reglets, recesses, and the like, to <br />prevent swelling and for easy removal.
