CAC Construction Methods — Questions and Answers
Question 1: Which construction method uses prefabricated components assembled on-site?
- Stick-built construction
- Modular construction (Correct answer)
- Tilt-up construction
- Masonry construction
Correct answer: Modular construction
Modular construction involves pre-made sections that are transported and assembled on-site, reducing build time.
Question 2: What is the primary advantage of tilt-up construction?
- It reduces material strength
- It speeds up construction for large buildings (Correct answer)
- It eliminates the need for a foundation
- It increases labor costs
Correct answer: It speeds up construction for large buildings
Tilt-up construction allows for faster and more cost-effective building of large concrete structures.
Question 3: Which construction method is commonly used for high-rise buildings?
- Balloon framing
- Steel frame construction (Correct answer)
- Adobe construction
- Earthbag construction
Correct answer: Steel frame construction
Steel frame construction provides the strength and flexibility required for high-rise buildings.
Question 4: Which material is most commonly used in reinforced concrete construction?
- Wood
- Rebar (reinforcing steel) (Correct answer)
- Fiberglass
- Aluminum
Correct answer: Rebar (reinforcing steel)
Rebar (reinforcing steel) is embedded in concrete to improve its tensile strength and durability.
Question 5: What is the primary benefit of using pre-stressed concrete in construction?
- It reduces concrete strength
- It increases strength and reduces cracking (Correct answer)
- It eliminates the need for reinforcement
- It makes construction slower
Correct answer: It increases strength and reduces cracking
Pre-stressed concrete enhances strength and reduces cracking by applying compressive force before loads are applied.
Question 6: Which construction technique minimizes heat loss in buildings?
- Balloon framing
- Insulated concrete forms (ICFs) (Correct answer)
- Open-web joist system
- Flat slab construction
Correct answer: Insulated concrete forms (ICFs)
Insulated concrete forms (ICFs) provide enhanced thermal efficiency and energy savings in building construction.
