These installation procedures have been developed from the experience of building contractors nationwide who use our products. While these procedures are recommended guidelines that work best in general, there are other acceptable techniques that may work as well for specific situations. Due to continued research and development, information contained in this manual may be added, deleted or revised. It is the responsibility of the user to make sure that they are using the most current information. Reward's website will always contain the most current information. Reward Wall Systems has no control over the installation, choice of materials and applications used in the installation of our product; therefore, Reward assumes no responsibility or warranty expressed or implied beyond the physical characteristics of the Reward product. *Any material or product that is applied in contact with the expanded polystyrene (EPS) foam plastic material of the iForm must be compatible. Petroleum, solvent, ketones, and esters based products are not compatible and will deteriorate the foam. The details in this manual are generic and conceptual in nature. Reward Wall Systems, Inc. is not responsible for final design, construction and compatibility. iForm by Reward Wall Systems provides formwork for a solid continuous flat cast-in-place concrete wall. It is nominally 16" high, 48" long, and comes in the following widths: • 9" (228 mm) wide - 4" (102 mm) flat core • 11" (279 mm) wide - 6" (152 mm) flat core • 13" (330 mm) wide - 8" (203 mm) flat core • 15" (381 mm) wide - 10" (254 mm) flat core • 17" (432 mm) wide - 12" (305 mm) flat core The size and shape of the iForm may vary by up to 0.75% of their specifications. iForm provides very strong formwork for placing concrete due to uniquely designed plastic form ties that maximize the concrete flow in the forms. The iForm tie is 1 ¼" (32 mm) wide and 6" (152 mm) on center and recessed ½" (12.7 mm). This makes applying all interior and exterior finishes easier than on similar forms. Additionally, the iForm's furring strip allows the acrylic finishes (stucco) to be applied without the problems associated with exposed steel or plastic furring strips. It is important to note that if the forms or bundles of forms are to be stored outside for an extended period of time, EPS foam and plastic ties must be protected from UV degradation. ADVICE AND ASSISTANCE can be obtained by contacting your local independent distributor, dealer or builder or the Reward Wall Systems, Inc. Technical Service Department, 800-468-6344, located at 9931 South 136th Street, Suite 100, Omaha, NE 68138-3936. Updated: April 2011 2 Release: K The New Standard for Sustainability. Planning and Preparation Spending time planning and preparing in advance of all phases of the construction process will make for an efficient and successful project. To get started you should read and understand the plans, educate and provide information to the building official, estimate the materials, have the proper tools and materials available and provide the right size crew. Taking the time to execute right the first time will provide happy customers and higher profits for the project. Specific items to consider when pre-planning for the project include storage of form bundles, access for concrete pump and trucks; establishing concrete delivery lead times; concrete and steel reinforcement requirements; construction of rough opening door and window bucks; coordination of concrete anchor bolts and embeds; coordination and layout of penetration sleeves; tool and material accessibility; and keeping a clean and accessible work site. It is important to know and understand the local building code in your area. Building a relationship with the local building official and providing them with information before the project starts is another key to success. Reward has received building code compliance with all national model building codes and other local building codes as shown in the following evaluation reports. United States ICC Evaluation Service ESR-1552 (IRC, IBC, UBC, BOCA, SBC) State of Wisconsin 200715-I Florida Product Approval FL 1743- R2 City of Los Angeles RR25418 City of New York MEA-116-03 Miami-Dade 08-0805.19 Canada Canada CCMC 13107-R ASTM- C578, E119 & E84 The International Residential Code (IRC) has adopted insulating concrete form prescriptive design for basement walls in section R404.4 and for above grade walls in section R611. Similarly, the Portland Cement Association and HUD have available prescriptive design prepared by the National Association of Home Builders Research Center. This document, PCA EB118, is titled The Prescriptive Method for Insulating Concrete Forms in Residential Construction. The PCA also has a document titled “PCA100-2007, Prescriptive Design of Exterior Concrete Walls for One and Two Family Dwellings.” ACI 332, Code Requirements for Residential Concrete is an additional
