1. What is the primary advantage of using prefabricated components in construction?
a) Reduced construction time
b) Increased construction cost
c) Higher flexibility in design
d) Lower quality control
Answer: a) Reduced construction time
Explanation: Prefabricated components are manufactured off-site, allowing for simultaneous site preparation and component production. This reduces the time needed for on-site assembly, accelerating the construction process.
2. Which type of construction method utilizes large panel constructions?
a) Traditional masonry
b) Timber frame
c) Steel frame
d) Reinforced concrete
Answer: b) Timber frame
Explanation: Large panel constructions are commonly associated with timber frame construction, where large panels prefabricated off-site are used for walls and floors.
3. Roof and floor slabs in prefabricated construction are typically made of which material?
a) Brick
b) Concrete
c) Steel
d) Wood
Answer: b) Concrete
Explanation: Prefabricated roof and floor slabs are often made of concrete due to its durability and strength.
4. Wall panels in prefabricated construction are known for their:
a) Weightlessness
b) Inflexibility
c) Customizability
d) High cost
Answer: c) Customizability
Explanation: Wall panels in prefabricated construction can be customized to fit specific design requirements, allowing for flexibility in architectural design.
5. What is the primary function of columns in prefabricated construction?
a) To support roof loads
b) To resist lateral loads
c) To provide insulation
d) To enhance aesthetics
Answer: a) To support roof loads
Explanation: Columns in prefabricated construction primarily serve to support the loads from the roof and transfer them to the foundation.
6. Shear walls in prefabricated construction are essential for:
a) Providing thermal insulation
b) Supporting vertical loads
c) Resisting horizontal loads
d) Enhancing acoustic performance
Answer: c) Resisting horizontal loads
Explanation: Shear walls in prefabricated construction are designed to resist lateral forces such as wind or seismic loads, enhancing the building’s structural integrity.
7. Which factor is crucial for the successful construction of prefabricated components?
a) On-site fabrication
b) Quality control
c) Manual labor
d) Traditional materials
Answer: b) Quality control
Explanation: Maintaining high-quality standards during the manufacturing and transportation of prefabricated components is essential for the success of prefabricated construction projects.
8. What role do connections play in prefabricated construction?
a) They provide insulation
b) They enhance aesthetics
c) They facilitate assembly
d) They improve ventilation
Answer: c) They facilitate assembly
Explanation: Connections in prefabricated construction enable the efficient and accurate assembly of prefabricated components on-site, contributing to the speed and ease of construction.
9. In prefabricated construction, what are “modular” components?
a) Components designed for temporary use
b) Components with fixed dimensions for easy assembly
c) Components requiring on-site fabrication
d) Components with complex designs
Answer: b) Components with fixed dimensions for easy assembly
Explanation: Modular components in prefabricated construction are manufactured with standardized dimensions to facilitate easy assembly and ensure compatibility with other prefabricated elements.
10. What distinguishes prefabricated construction from traditional construction methods?
a) On-site fabrication
b) Customizability
c) Simultaneous construction activities
d) Use of manual labor
Answer: c) Simultaneous construction activities
Explanation: Prefabricated construction allows for simultaneous activities such as site preparation and component fabrication, which significantly reduces construction time compared to traditional methods that rely more on sequential processes.
