Answers with Detailed Rationales |
Complete Exam Prep & Study Guide
1. Before beginning a structural demolition project, which condition should be
verified first?
A. The equipment has been delivered
B. The debris containers are on site
C. The structure has been properly surveyed and hazards identified
D. The final cleanup crew is scheduled
Answer: C. The structure has been properly surveyed and hazards identified
Rationale: A pre-demolition survey identifies structural conditions, hazardous
materials, utilities, adjacent-property risks, and other hazards that affect the
demolition sequence and means of protection.
2. What is the primary purpose of a pre-demolition engineering survey?
,A. To determine the contractor's profit margin
B. To identify structural conditions and potential collapse hazards
C. To determine the color of demolition equipment
D. To establish the project's final landscaping design
Answer: B. To identify structural conditions and potential collapse hazards
Rationale: The survey helps determine how the structure will behave during
removal and whether special shoring, bracing, sequencing, or engineering
controls are necessary.
3. Which condition presents the greatest immediate concern when demolishing
a partially damaged building?
A. Old paint colors
B. Unstable structural members
C. Minor interior finishes
D. Existing floor coverings
Answer: B. Unstable structural members
Rationale: Unstable members can fail without warning and cause fatalities,
equipment damage, or uncontrolled collapse.
4. When demolishing a load-bearing wall, the contractor should generally:
A. Remove it without analyzing the remaining structure
B. Determine how loads are being supported and establish a controlled sequence
C. Remove adjacent columns first
D. Allow workers to stand directly beneath the wall
Answer: B. Determine how loads are being supported and establish a controlled
sequence
Rationale: Removing load-bearing components can redistribute loads and
trigger progressive collapse unless the sequence is properly engineered and
controlled.
,5. What is the safest approach when an existing utility cannot be positively
identified?
A. Assume it is abandoned
B. Proceed slowly with hand tools only
C. Treat it as energized or active until properly verified
D. Cover it with debris
Answer: C. Treat it as energized or active until properly verified
Rationale: Unknown utilities must not be assumed safe. Verification and proper
isolation are essential before demolition work proceeds.
6. Which utility should receive particular attention because an accidental
release may create an explosion hazard?
A. Stormwater piping
B. Natural gas
C. Sanitary sewer
D. Fiber-optic cable
Answer: B. Natural gas
Rationale: Natural gas leaks can create explosive atmospheres, making
identification, isolation, testing, and verification critical.
7. What should be established before mechanical demolition begins?
A. A controlled demolition sequence
B. A public advertising schedule
C. A landscaping contract
D. A building occupancy schedule
Answer: A. A controlled demolition sequence
Rationale: Planned sequencing prevents unintended load transfers, uncontrolled
collapse, equipment conflicts, and worker exposure.
, 8. Why should debris accumulation on floors be controlled during demolition?
A. It improves the appearance of the site
B. It prevents excessive loading and potential floor failure
C. It reduces equipment fuel consumption
D. It eliminates the need for barricades
Answer: B. It prevents excessive loading and potential floor failure
Rationale: Demolition debris can impose loads far beyond the original design
assumptions, particularly on weakened or partially demolished floors.
9. Which condition most strongly indicates that a structure may require
additional shoring before demolition?
A. Freshly painted walls
B. Significant structural deterioration or unexpected movement
C. New light fixtures
D. Recently installed carpeting
Answer: B. Significant structural deterioration or unexpected movement
Rationale: Deterioration and movement can indicate compromised structural
capacity and require engineering evaluation and temporary support.
10. What is the primary purpose of an exclusion zone during demolition?
A. To store office furniture
B. To keep unauthorized persons outside the hazard area
C. To provide parking for visitors
D. To store drinking water
Answer: B. To keep unauthorized persons outside the hazard area
Rationale: Demolition creates falling-object, collapse, dust, equipment, and
other hazards requiring separation between workers and unauthorized persons.
