B. Design of formwork, shoring, and reshoring shall conform to ACI 117, ACI 301, ACI 318, and
ACI 347.
C. Design formwork in a manner such that existing or new construction is not overloaded.
1.6 ARCHITECTURAL CONCRETE MOCK-UP
A. Provide a mock-up as shown in the Drawings using the products and practices specified for
Architectural Concrete to be reviewed and approved by the Architect.
B. Mock-up shall be protected for the duration of the construction and will be used as the basis of
acceptance for constructed work.
PART 2 PRODUCTS
2.1 FORM MATERIALS
A. Form Material: Wood, plywood, metal, fiberglass or a combination of these, with sufficient
strength to prevent distortion.
B. Form Definitions
1. Standard Forms: No form-facing material required. Standard forms are acceptable
everywhere except for Architectural Concrete elements.
2. Architectural Concrete Forms: Form-facing material shall be plywood, tempered concrete-
form-grade hardboard, metal (unrusted) or plastic that will produce a smooth, uniform
texture on the concrete. Do not use form-facing material with raised grain, torn edges, worn
edges, patches, dents, or other defects that will impair the texture of the exposed concrete
surfaces. Intent is that when the forms are removed, the exposed concrete surfaces will be
free from all blemishes. Architectural concrete forms are required for all concrete elements
indicated as Architectural Concrete.
2.2 FORMWORK ACCESSORIES
A. Formwork Accessories: Commercially manufactured products, including ties and hangers. Do
not use nonfabricated wire form ties.
2.3 FORM RELEASE AGENT
A. Form release agent shall not bond with, stain, nor adversely affect concrete surfaces.

2.4 VAPOR RETARDER
A. Vapor Retarder
1. Polyethylene sheet, not less than 10 mils thick, complying with ASTM E1745, Class A, B,
and C.
2. Maximum Permeance: ASTM E96: 0.04 perms (US).
3. Seam Tape: High Density Polyethylene Tape with pressure sensitive adhesive; minimum
width of 4 inches.
4. Pipe Boots: Construct pipe boots from vapor barrier material and seam tape in accordance
A. Comply with Section 01330 - Submittal Procedures.
B. Product Data: Submit manufacturer's product data, including surface preparation and application instructions. Submit manufacturer's maintenance and cleaning instructions.
1.4 DELIVERY, STORAGE, AND HANDLING
A. Delivery: Deliver materials to site in manufacturer's original, unopened containers and packaging, with labels clearly identifying manufacturer and product name.
B. Storage: Store materials in a clean, dry area indoors in accordance with manufacturer's
instructions. Keep containers sealed until ready for use. Keep away from ignition sources. Do not allow to freeze.
C. Handling: Protect materials during handling and application to prevent damage or
contamination. 1.5 ENVIRONMENTAL REQUIREMENTS
