BUILDING CONSTRUCTION FINAL EXAM
QUESTIONS AND ANSWERS COMPLETE
RATED A.
1. Disadvantage of Using Wood in Construction
Question: What is a disadvantage of using wood in construction?
Correct Answer: Weather conditions can affect the size and shape of wood.
Explanation: Wood is susceptible to expansion and contraction due to
moisture and temperature changes.
2. Types of Solid Lumber
Question: Solid lumber includes dimensional lumber, boards, and:
Correct Answer: timbers.
Explanation: Timbers are large, solid wood pieces used for heavy-duty
structural applications.
3. Advantages of Engineered Wood Products
Question: Engineered wood products have many advantages, including:
Correct Answer: strength and cost efficiency.
Explanation: These products are designed for superior performance and
economical use.
4. Wood-Like Product from Wood Fiber and PVC
Question: Which of the following is a wood-like product made from wood fiber
and polyvinyl chloride (PVC)?
Correct Answer: Thermoplastic composite lumber.
,Explanation: This material combines the durability of wood fiber with the
resilience of PVC.
5. Fire Spread Prevention in Combustible Construction
Question: What do building codes require to prevent the rapid spread of fire
through concealed spaces within combustible construction?
Correct Answer: Firestopping.
Explanation: Firestopping blocks concealed pathways, reducing fire spread
risk.
6. Function of Siding
Question: Which of the following provides weather protection and may
contribute to the appearance of a building's exterior walls?
Correct Answer: siding.
Explanation: Siding protects the structure while enhancing its aesthetic
appeal.
7. Challenge with Exterior Veneer on Wood-Frame Buildings
Question: One of the problems firefighters face in wood-frame buildings with
exterior brick or stone veneer is:
Correct Answer: difficulty in visually determining whether the brick or
stonework is structural or aesthetic.
Explanation: This can impact firefighting strategies and safety assessments.
8. Increasing Fire Resistance in Wood-Frame Buildings
Question: A typical means of adding or increasing fire resistance of a wood-
frame building is through the use of 5/8 inch (15.5 mm) ____ attached to the
studs and ceiling joists.
, Correct Answer: gypsum board.
Explanation: Gypsum board provides a fire-resistant barrier, improving safety.
9. Thermal Decomposition of Wood
Question: The thermal decomposition of wood that begins at a temperature
below approximately 392°F (200°C) is known as:
Correct Answer: pyrolysis.
Explanation: Pyrolysis releases flammable gases that can fuel a fire.
10. Requirement for Ignition-Resistant Construction
Question: Which of the following is an applicable requirement for ignition-
resistant construction?
Correct Answer: Limitations on the size of attic and under-floor vents and
their protection with corrosion-resistant screens.
Explanation: These measures reduce the risk of fire entering the structure.
11. Fire Resistance of Heavy Timbers vs. Light-Frame Construction
Question: Which of the following statements regarding the structural
endurance of wood under fire conditions is MOST accurate?
Correct Answer: Heavy timbers display greater structural endurance under
fire conditions than light-frame construction.
Explanation: Heavy timbers char on the outside, slowing fire penetration.
12. Definition of "Frame Buildings"
Question: "Frame buildings" are generally understood to be constructed of:
Correct Answer: wood.
Explanation: Wood-frame construction is common for residential and light
commercial buildings.
