Disclaimer:
The information presented in this course gives the participant the necessary guidance and basic knowledge of proper installation techniques for using the various products composing the Nudura Integrated Building Technology and associated accessories (the “Nudura Products”).
This course DOES NOT train an individual how to be a contractor. Nudura Inc. and Nudura Systems, Inc. do not have any control over the installation or workmanship used in the assembly or installation of the Nudura Products, whether by recognized Nudura trained installers or by unauthorized installers

Safety FirstPersonal Protective Equipment (PPE):
Hard hats Safety bootsSafety glassesProtective gloves
Where erecting scaffolding or alignment system, all local safety codes and regulations must be met.Keeping a clean and efficient job site results in less chance of injury.Take proper precautions to protect workers from protruding rebar.

Getting Started
![Page 6: Nudura Online Basic Installation Training – Module Two CAN](https://reader031.fdocuments.us/reader031/viewer/2022020916/61ae1fcd060bf165c91936db/html5/thumbnails/6.jpg)
Drawing & Contract Documents Plans should include:
1. ICF concrete core size for all walls
2. Footing design and dowel spacing
3. Rebar design for all walls
4. Rough opening sizes
5. Lintel schedule with rebar layout
6. Floor and roof connection details

Guidelines for ReinforcingBuilding codes recognize ICFs as - flat, monolithic, reinforced concrete walls with EPS foam plastic insulation on both sides of the concrete core
Reinforcement for residential construction is in the building code and follows concrete design standards
NUDURA has ‘Prescriptive’ engineered reinforcement tables that may be followed
Insulation

Guidelines for Reinforcing Project reinforcing shall be as per the plans and specifications
Advantages of ICF over conventional forming:
• Minimal Tie Wiring
• Order of Steel Placement
• No Tie Wiring at Footings
![Page 9: Nudura Online Basic Installation Training – Module Two CAN](https://reader031.fdocuments.us/reader031/viewer/2022020916/61ae1fcd060bf165c91936db/html5/thumbnails/9.jpg)
Guidelines for Reinforcing Horizontal Steel Placement:
• Web capture lugs allows for precise location of horizontal reinforcing steel
• Multiple capture lugs allow for varying steel locations
• Capture lugs eliminate need for tie wiring
![Page 10: Nudura Online Basic Installation Training – Module Two CAN](https://reader031.fdocuments.us/reader031/viewer/2022020916/61ae1fcd060bf165c91936db/html5/thumbnails/10.jpg)
Guidelines for Reinforcing Horizontal and Vertical Steel
Specification:
• Horizontal Reinforcement should be specified at 18” (457mm) on center
• Vertical Reinforcement should be specified at 8” (203mm) increments
• Larger diameter reinforcement should be considered if different spacing is specified
Vertical Steel Placement:
• Reinforcement is woven between the offset horizontal reinforcement
• Install reinforcement against the web
• Concrete pressure ensures reinforcement alignment
