Study Notes
Building Construction Standards and Practices
-
Emergency Escape and Rescue Openings: Sill height maximum 44 inches.
-
Ice Barriers (Eaves): At least two layers of underlayment cemented together, in areas prone to ice build-up.
-
Window Wells: Need a horizontal area of at least 9 square feet & 36 inches minimum width/projection.
-
Ground Sloping: Minimum 6 inches slope within first 10 feet of building perimeter.
-
Exterior Caulking: Silicone rubber and urethane caulks are ideal for exterior building applications.
-
Basement Vapor Retarders (Some Climates): Avoid low permeability materials (polyethylene, vinyl wallpaper) on interior basement walls. They trap moisture.
-
Carpet/Wood on Slabs on Grade: Can be applied directly if slab or surface temperature is near room temperature.
-
Composition Shingle Roof Slope: Minimum 2:12 slope (2 inches rise : 12 inches run).
-
Deck Load Distribution: Weight is carried and distributed by posts and the deck-to-house connection.
-
Deck Post Dimensions: Minimum 6 inches by 6 inches; Maximum 12 feet, unless cross-braced then 14 feet allowed.
-
Air Conditioning Evaporator Coil Temperature Drop: Around 20 degrees Fahrenheit during operation.
-
Gas Piping Material: Black iron is commonly used.
-
Dew Point: Temperature at which air cools to reach water vapor saturation, causing condensation.
-
Intermediate Rail/Baluster Load: Can withstand 50 pounds on a 1 square foot area.
-
Residential Framing Method: Platform framing is typical.
-
Gableless Roof: A hip roof.
-
NACHI Member Repair Restriction: No repairing or offering related services to inspected structures for 12 months.
-
Storm Collar Function: Directs rainwater away from the chimney flue, preventing water damage.
-
Chimney Height (3-2-10 Rule): At least 3 feet above highest roof penetration and 2 feet above any building part within 10 feet horizontally.
-
Chimney Flue Sizing: Based on fireplace opening area.
-
Air Conditioning System Minimum Outdoor Temperature: Do not operate below 60 degrees Fahrenheit.
-
Multiple Sink Discharge: Dishwasher, food grinder, and sink can discharge into one 1.5-inch drain.
-
Flat Roof Venting: Passive venting systems are recommended, but ponding can be a problem.
-
Sloped Roof Venting (Asphalt Shingles): Combination soffit (intake) and ridge vents (exhaust) are most effective.
-
Mid-Efficiency Furnace Ratings: Typically 78-82% AFUE; intermittent pilot is a main feature.
-
Plumb Bob Use: Creating a vertical reference line for straightness.
-
Egress Door Minimum Dimensions: 3 feet wide by 6 feet 8 inches tall.
-
Slab Floor Barrier: Vapor barrier (6-mil poly) or equivalent moisture barrier needed below slabs.
-
Basement Insulation Covering: Semi-permeable rigid foam insulation in basements must be covered with fire-resistant material (e.g., gypsum) to prevent combustion.
-
Roof Deck Ventilation: To reduce roof deck temperature and improve shingle performance, especially during hot weather.
-
Notch Length on Lumber: Maximum length of notches in joists, rafters, and beams is one-third of the member's depth.
