1. What is the primary purpose of a demolition plan before work
begins?
A. To determine the color of the replacement building
B. To establish a safe and organized sequence for removing the
structure
C. To eliminate the need for site inspections
D. To determine the property's future tax value
Answer: B. To establish a safe and organized sequence for removing
the structure
Rationale: A demolition plan identifies the structure, hazards, utilities,
work methods, equipment, sequencing, and protective measures
necessary for safe demolition. Proper planning helps prevent
,uncontrolled collapse, utility incidents, exposure hazards, and damage
to surrounding property.
2. Before demolition begins, which condition should be verified
regarding utilities?
A. Utilities should remain energized until demolition is complete
B. Only electrical service needs to be addressed
C. Utilities should be properly identified, disconnected, capped, or
otherwise controlled as required
D. Utilities can be ignored if the building is vacant
Answer: C. Utilities should be properly identified, disconnected,
capped, or otherwise controlled as required
Rationale: Uncontrolled electrical, gas, water, sewer, steam, and
other utility services can create serious hazards during demolition. The
contractor should coordinate with utility owners and verify that
services have been appropriately disconnected or controlled before
hazardous work begins.
3. Which demolition method generally involves taking a structure
apart systematically from the top downward?
,A. Bottom-up demolition
B. Top-down demolition
C. Random demolition
D. Flood demolition
Answer: B. Top-down demolition
Rationale: Top-down demolition removes portions of a structure
progressively from higher levels toward lower levels. This approach
can provide better control over structural stability and debris
movement when properly planned and executed.
4. What is a major concern when removing structural members
during demolition?
A. Increasing the building's occupancy
B. Maintaining adequate structural stability throughout the operation
C. Improving interior decoration
D. Increasing natural lighting
Answer: B. Maintaining adequate structural stability throughout the
operation
Rationale: Removing beams, columns, walls, floors, or other load-
bearing components can change how loads are distributed.
, Demolition must therefore proceed according to a planned sequence
that prevents premature or uncontrolled collapse.
5. Which professional is commonly responsible for determining the
structural condition of a building when specialized structural
evaluation is necessary?
A. Landscape designer
B. Structural engineer
C. Interior decorator
D. Property appraiser
Answer: B. Structural engineer
Rationale: A structural engineer can evaluate load-bearing systems,
deterioration, unusual conditions, and demolition sequencing where
engineering judgment is required. Their involvement can be
particularly important for complex or partially damaged structures.
6. What should a contractor do if unexpected structural conditions
are discovered during demolition?
A. Continue at the same pace regardless of the condition
B. Increase equipment speed
