A. 
Forms.
Full size, moisture resistant, three-fourths (3/4) inch thick, 5-ply Douglas fir form plywood shall be used as form lumber. Joints in forms shall be horizontal or vertical. Metal or other types of forms are allowed only with the prior approval of the City of Magnolia, Engineer or designated representative of the Engineer and shall produce surfaces equal to those by the specified wood forms.
1. 
Exposed Surfaces.
Form lumber for exposed surfaces shall meet the above size and type requirements and be faced Grade B, or better, plywood. Do not use material with raised grain, torn surfaces, patches, dents, warps, knots, or other defects.
2. 
Unexposed Surfaces.
Undressed lumber may be used for forming unexposed surfaces.
B. 
Form Ties.
Form ties for exposed surfaces shall be threaded rod type or snap ties and shall be of sufficient strength to withstand the pressure resulting from the placement of the concrete. Threaded rod type form ties shall be at least one and one-half (1-1/2) inches shorter than the wall thickness. Form ties shall be such that when forms are removed, no metal is closer that three-quarters (3/4) inch from the surface and shall leave a small, clean hole to be grouted. Securing forms with wire is strictly prohibited.
C. 
Form Coating.
Use commercial formulation of form oil or form-release agent having proven satisfactory performance. Coating must not bond with, stain, or adversely effect the concrete surfaces and shall not impair the use of bonding agents and curing compounds. If form oil is used, all excess oil shall be wiped off leaving the surface just oily to the touch.
D. 
Chamfer Strips.
Provide chamfer strips in corners of forms to produce beveled edges on permanently exposed surfaces. Size of chamfer shall be three-quarters (3/4) inch unless shown otherwise on the plans. Interior corners and edges of formed joints do not require any beveling unless shown otherwise on the plans.
E. 
Earth Cuts for Forms.
Use earth cut forms for beams under slabs on grade when the beam has sloped sides and is integral with the slab. Earth cut forms are allowable for sides of footings if the sides of the excavation are stable such that there is no caving or sloughing.
F. 
Slip Forms.
Slip forming is not permitted.
