1. Which of the following is the primary purpose of a demolition plan in a
construction project involving structural removal and site clearing
operations?
A. To determine final building aesthetics
B. To maximize salvage value of materials only
C. To ensure systematic, safe, and compliant removal of structures
D. To reduce project documentation requirements
Answer: C
Rationale: A demolition plan is essential for outlining procedures,
safety precautions, sequencing, and regulatory compliance to ensure
structures are removed safely and efficiently without endangering
workers or the public.
2. Prior to beginning demolition activities, which document is most
critical for identifying hazardous materials such as asbestos and lead-
based paint?
, A. Structural load analysis report
B. Environmental hazard survey
C. Equipment maintenance log
D. Soil compaction test results
Answer: B
Rationale: An environmental hazard survey identifies dangerous
substances like asbestos and lead that must be properly handled and
removed before demolition begins to comply with safety regulations.
3. What is the most appropriate method for demolishing a multi-story
building in a densely populated urban area where space is limited?
A. Implosion
B. Wrecking ball
C. Selective or manual demolition
D. High-reach excavator only
Answer: C
Rationale: Selective or manual demolition allows for precise removal
of structural components in confined areas, minimizing risk to
adjacent structures and the public.
4. Which safety measure is required when performing demolition work
at heights exceeding 6 feet?
A. Steel-toe boots only
B. Fall protection systems
C. Hearing protection
D. Respiratory masks only
Answer: B
Rationale: Fall protection systems such as harnesses and guardrails
are required to prevent worker injury or death when working at
elevated heights.
5. What is the primary function of shoring during demolition operations?
A. To improve site drainage
B. To support unstable structures temporarily
C. To reduce dust emissions
D. To increase equipment efficiency
Answer: B
Rationale: Shoring provides temporary structural support to prevent
, collapse during demolition, especially when removing load-bearing
components.
6. Which piece of equipment is most commonly used for large-scale
structural demolition?
A. Concrete mixer
B. High-reach excavator
C. Bulldozer
D. Backhoe loader
Answer: B
Rationale: High-reach excavators are specifically designed for
controlled demolition of tall structures, allowing operators to
dismantle buildings from a safe distance.
7. Before demolition begins, utilities such as gas, water, and electricity
must be:
A. Left operational for equipment use
B. Relocated underground
C. Identified and disconnected
D. Increased in capacity
Answer: C
Rationale: Disconnecting utilities prevents hazards such as
explosions, flooding, or electrocution during demolition operations.
8. Which term describes the careful dismantling of a structure to
preserve materials for reuse?
A. Implosion
B. Deconstruction
C. Excavation
D. Compaction
Answer: B
Rationale: Deconstruction involves methodical removal of building
components to salvage materials, promoting sustainability and
reducing waste.
9. What is the main hazard associated with uncontrolled structural
collapse during demolition?
A. Reduced project cost
B. Increased salvage value
