TRANSCRIPT
Nudura Online Basic Installation Training– Module Two CAN
Objectives:To deliver an overview of Nudura ICF products, benefits of building with ICF’s, and a best practice guide for ICF installation.
Agenda:Module follows the NuduraInstallation Manual and Product Guide.
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
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
Insulation
Flat Wall Concrete
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
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
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
Appendix D & E• Provide NUDURA friendly reinforcement requirements• Engineered for Canada and USA
• Commonly acceptable worldwide
Appendix D & E Important to note:• Developed and stamped by Professional Engineers for both Canada and the USA
• Tables based on residential construction with light frame floors & roofs only
Designed for:
• 3,000 lbs/in2 or 20 MPa concrete• 60,000 lbs/in2 or 400 grade reinforcing steel
Limitation set by engineers in each Appendix
Appendix D & EAppendix D- Below Grade Wall Design
Five key pieces of data required:
1. Concrete Core Thickness
2. Height of Wall
3. Height of Backfill
4. Soil Fluid Pressure
5. Seismic Category
Appendix D & EExample exercise:
Appendix D - Below Grade Wall Design
• Concrete Core 150mm (6” )
• Height of Wall 2.74m (9.0’)• Height of Backfill 2.44m (8.0’)• Backfill Soil Condition Sand, Gravel with Silt or Clay
• Seismic Zone Sa(0.2) = 0.12
Appendix D & EAppendix D- Above Grade Wall Design
Five key pieces of data required:
1. Concrete Core Thickness
2. Wall Position (1st Floor or 2nd Floor)
3. Height of Wall
4. Seismic Zone
5. Hourly Wind Pressure
Appendix D & EExample exercise:Appendix D- Above Grade Wall Design
• Concrete Core 150mm (6” )• Wall Position Lower floor of 2 storey structure supporting 2nd storey concrete
walls and wood frame floor & roof• Height of Wall 2.74m (9.0’)• Seismic Zone Sa(0.2) ≤ 0.32• Hourly Wind Pressure q1/50 ≤ 0.7 5kPa (15.7 psf)
Appendix D & E Appendix E- Lintel Reinforcement Design
• Tables designed to resist Uniformly Distributed Loads (UDL) Only
• Point loads (beams, girder trusses, etc.) have not been taken into account in the design tables

Components of a Lintel
Appendix D & E
Appendix E- Lintel Reinforcement Design
UDL can be calculated or obtained from floor/roof supplier
To calculate UDL:Determine Live (LL) and Dead (DL) LoadsDetermine floor or roof span
UDL = (DL + LL) x ½ floor or roof span
Appendix D & E
Appendix E- Lintel Reinforcement Design
Four pieces of data required:
1. Concrete Core Thickness
2. Depth of Lintel
3. Width of Opening
4. Uniformly Distributed Load (UDL)
Appendix D & EExample exercise:
Appendix E- Lintel Reinforcement Design
• Concrete Core 6” (150mm)
• Depth of Lintel 18” (450mm)
• Width of Opening 6’-0” (1800mm)
•Uniformly Distributed Load (UDL)
• LL= 195.3 kg/m2 • DL= 24.4 kg/m2• Clear Floor Span= 9.75m
UDL= (1.9+0.24)(9.75/2) =10.43 KN/m
