1. What is the primary purpose of a building code?
A. To increase construction costs
B. To ensure minimum standards for safety, health, and structural integrity
C. To regulate contractor profits
D. To eliminate the need for inspections
Rationale: Building codes are established to protect public health, safety, and
welfare by setting minimum construction standards. They are not designed to
increase costs or regulate profits but to ensure structures are safe, durable, and
habitable.
2. Which document is typically required before starting major construction
work?
A. Warranty certificate
B. Building permit
C. Insurance claim form
D. Material delivery invoice
Rationale: A building permit is required by local authorities before construction
begins to ensure compliance with zoning laws and building codes. It allows
regulatory review before work proceeds.
3. What is the main function of concrete rebar?
A. Increase aesthetic value
B. Reduce construction time
, C. Provide tensile strength to concrete structures
D. Replace cement entirely
Rationale: Rebar reinforces concrete, which is strong in compression but weak in
tension. Steel reinforcement provides tensile strength, preventing cracking and
structural failure.
4. Which of the following is a load-bearing component?
A. Drywall paint
B. Ceiling tile
C. Window blinds
D. Structural beam
Rationale: A structural beam carries loads from floors, roofs, or walls and
transfers them to columns or foundations. Non-structural elements do not bear
loads.
5. What does OSHA primarily regulate?
A. Building design aesthetics
B. Workplace safety and health standards
C. Architectural licensing
D. Real estate pricing
Rationale: OSHA establishes and enforces safety standards in workplaces,
including construction sites, to prevent accidents and injuries.
6. Which soil type has the highest load-bearing capacity?
A. Clay
B. Silt
C. Dense gravel
D. Peat
Rationale: Dense gravel provides excellent compaction and drainage, making it
highly stable for supporting structural loads compared to weaker soils like clay
or peat.
, 7. What is the purpose of a footing in foundation construction?
A. Decorative support
B. Electrical grounding
C. Roofing stabilization
D. Distribute structural loads to soil
Rationale: Footings spread the load of a structure over a larger soil area,
reducing pressure and preventing settlement or failure.
8. Which material is most commonly used for residential framing?
A. Aluminum
B. Concrete
C. Brick
D. Wood lumber
Rationale: Wood lumber is widely used in residential construction due to its
availability, cost efficiency, and ease of installation compared to steel or
masonry.
9. What is the function of a vapor barrier?
A. Increase insulation R-value
B. Prevent moisture transmission through walls
C. Strengthen structural framing
D. Improve electrical conductivity
Rationale: Vapor barriers prevent moisture from penetrating walls and floors,
reducing mold growth and structural deterioration caused by condensation.
10.Which of the following best describes a change order?
A. A safety inspection report
B. A labor contract
C. A formal modification to the construction contract scope
D. A building permit renewal
Rationale: A change order documents approved modifications to the original
construction contract, including scope, cost, or schedule changes.
