A. 
General.
At least 24 hours prior to scheduled concrete placement, notify the Engineer or designated representative of the Engineer that formwork is ready to be inspected. Do not place concrete until forms have been inspected and approved by the Engineer or designated representative of the Engineer.
B. 
Preparation of Form Surfaces.
Clean all surfaces of forms and embedded objects before placement of concrete. Remove accumulated mortar, grout, rust, debris and any other foreign material. Coat forms for exposed or painted surfaces with form oil or other form-release agent before placing concrete. Form oil, or other form-release agent, shall be used in strict accordance with the manufacturer’s printed instructions. Do not allow excess form coating material to accumulate in forms or come in to contact with previously placed hardened concrete against which fresh concrete will be placed. No form coating material shall be placed on the reinforcement. Other than retained-in-place metal forms, forms for unexposed concrete surfaces may be wetted with water immediately prior to placement of concrete in lieu of using a form coating material. Such wetting of forms with water is not allowed when the possibility of freezing temperatures exists.
(Ordinance 2007-106, App. B, adopted 3/20/07)
A. 
General.
Construct forms to the shape, lines and dimensions of the members as shown on the plans. Forms shall be sufficiently tight to prevent the leakage of mortar. Temporary openings shall be provided at the base of column and wall forms or at other required points to facilitate the cleaning and inspection immediately before placement of concrete.
B. 
Facing Material.
Facing material for exposed surfaces shall be placed in an orderly and symmetrical fashion. Full size pieces shall be used except where small pieces will cover an entire area. Facing material shall be adequately supported to prevent deflection. Facing material for exposed surfaces shall be installed in such a manner that will allow the Engineer or designated representative of the Engineer access to inspect the exposed surface forms before the back form is in place.
C. 
Bracing of Forms.
Anchor, brace, and tie all formwork to shores, members, or other supporting surfaces to prevent the upward movement of the forms during the placement of concrete. Tighten forms to close joints and insure conformance to the specified lines and shapes. All forms that cannot be properly tightened shall be removed and rebuilt. All forms shall be securely braced to prevent lateral deflections during placement of concrete. Use wedges or jacks to provide positive adjustment of shores and struts. For wall openings, construct wood forms that facilitate loosening to counteract swelling of forms.
D. 
Shoring of Forms.
When shoring is permitted or required, construction shall follow a planned sequenced. Such plan shall be provided by the Contractor and shall be approved by the Engineer or designated representative of the Engineer prior to construction.
E. 
Removal of Forms.
Forms for structural slabs and beam bottoms shall remain in place for a period of fourteen (14) days or until cylinder tests have shown that the concrete has reached eighty (80) percent of 28-day design strength as evidenced by laboratory test reports. In no case shall forms be removed in less than four (4) days.
F. 
Form Reuse.
Approval is required before reusing any forms. Do not reuse forms that are worn or damaged beyond repair. Thoroughly clean and recoat forms before reuse. For wood forms to be used for exposed surfaces, sand or otherwise dress the surface to be in contact with the concrete to the original condition or provide form liner facing material. Before reusing metal forms, straighten, remove dents and clean such that the forms are returned to original condition.
