i <br />2. Subsequent reuses of the forms without recoating shall be permitted <br />r at the discretion of the Engineer, but forms shall not be used more <br />than three times without recoating. <br />3. After application, any surplus material on the form surfaces and/or <br />the reinforcing steel shall be removed. <br />4. Forms for unexposed surfaces may be thoroughly wetted with water <br />in lieu of coating immediately before the placing of concrete. <br />3.02 Installation <br />A. General <br />1. Forms, complete with centering, cores and molds, shall be <br />constructed to conform to the shape, form, line and grade required, <br />and shall be maintained sufficiently rigid to prevent deformation <br />under load. <br />2. For narrow walls and columns, where the bottom of the form is <br />inaccessible, the lower form boards shall be left loose so that they <br />may be removed for cleaning out extraneous material immediately <br />before placing the concrete. <br />• 3. The forms shall be maintained at a temperature which will not ad- <br />versely affect the curing of the concrete. <br />4. Formed voids in concrete, where used, shall be of accurate <br />- dimensions in size and location in order that the thickness of <br />surrounding concrete shall not be reduced from drawing dimensions. <br />B. Joints <br />All corners of columns, girders, beams and walls, and other exposed joints, <br />unless otherwise indicated on the Drawings or directed by the Engineer, shall <br />be beveled, rounded, or chamfered by moldings placed in the form. <br />C. Liners <br />1. Forms for exposed surfaces shall have a form liner of an approved <br />type and shall be mortar-tight. <br />2. Unless otherwise specified, the forms for exposed surfaces down to an <br />elevation of one foot below low water or 2 feet below final ground <br />line above water, shall be faced with metal, plyboard or other <br />approved smooth-faced composition material constructed to provide a <br />minimum of joints and leakage. <br />3. All fittings for metal ties shall be of such design that, upon their <br />• removal, the cavities which are left will be of the smallest possible <br />size. <br />4. The cavities shall be filled with cement mortar and the surface left <br />sound, smooth, even and uniform in color. <br />03100-4 <br />
