CDS Project Planning & Scheduling 3 — Questions and Answers
Question 1: What is the purpose of establishing an exclusion zone around a demolition site?
- To reserve parking for contractors
- To prevent unauthorized persons from entering areas where they could be struck by falling debris or equipment (Correct answer)
- To mark where debris will be stockpiled
- To define property tax boundaries
Correct answer: To prevent unauthorized persons from entering areas where they could be struck by falling debris or equipment
An exclusion zone protects workers and the public from struck-by hazards caused by falling materials, swinging equipment, and demolition debris.
Question 2: When preparing a demolition project schedule, which resource is typically tracked on a resource-loaded schedule?
- Local weather patterns
- Labor hours, equipment, and major materials assigned to each task (Correct answer)
- Names of neighboring property owners
- Permit expiration dates only
Correct answer: Labor hours, equipment, and major materials assigned to each task
A resource-loaded schedule assigns labor hours, equipment, and key materials to each task so supervisors can identify conflicts and over-allocations.
Question 3: A project owner requests an accelerated demolition schedule. What should the CDS supervisor evaluate FIRST?
- Whether workers prefer overtime
- Whether the accelerated schedule can be achieved safely with available resources and regulatory compliance (Correct answer)
- The color of safety fencing available
- How to defer the pre-demolition survey
Correct answer: Whether the accelerated schedule can be achieved safely with available resources and regulatory compliance
Safety feasibility and regulatory compliance must be assessed before committing to an accelerated schedule to prevent unsafe shortcuts.
Question 4: Which of the following is a key element of a demolition project's contingency plan?
- Marketing materials for the new building
- Predefined responses to foreseeable risks such as utility strikes, structural collapse, or hazmat discovery (Correct answer)
- Employee holiday schedules
- Paint color selections
Correct answer: Predefined responses to foreseeable risks such as utility strikes, structural collapse, or hazmat discovery
A contingency plan documents predefined responses to foreseeable risks, enabling rapid, organized action when unexpected events occur.
Question 5: In a demolition contract, a 'milestone' typically represents:
- A unit of measurement for debris
- A significant event or completion point used to track project progress (Correct answer)
- A type of foundation anchor
- A surveying marker on the property boundary
Correct answer: A significant event or completion point used to track project progress
A milestone is a key project event—such as completing hazmat abatement or structural demolition—used to measure and communicate project progress.
Question 6: Why is utility disconnection and capping a prerequisite step listed in most demolition project plans?
- To reduce the building's market value
- To eliminate risks of electrocution, gas explosions, flooding, and communication line damage during demolition (Correct answer)
- To satisfy aesthetic requirements
- To speed up permit approvals
Correct answer: To eliminate risks of electrocution, gas explosions, flooding, and communication line damage during demolition
Disconnecting and capping utilities before demolition eliminates energized, pressurized, or flowing systems that could cause electrocution, fire, explosion, or flooding.
Question 7: A CDS supervisor is planning a project near an occupied building. Which planning control is MOST important to address vibration risks?
- Scheduling all work during daylight hours
- Conducting a vibration analysis and setting equipment operational limits to protect adjacent structures and occupants (Correct answer)
- Painting equipment bright colors
- Increasing crew size to finish faster
Correct answer: Conducting a vibration analysis and setting equipment operational limits to protect adjacent structures and occupants
A vibration analysis establishes safe operational limits for equipment to prevent structural damage or injury to adjacent occupied buildings.
