1. In construction project scheduling, which technique best describes the
Critical Path Method (CPM) and its primary function in project
planning and control?
A. A probabilistic model used only for cost forecasting
B. A scheduling technique that identifies resource leveling priorities
only
C. A deterministic method that determines the longest sequence of
dependent activities affecting project duration
D. A risk analysis tool used for weather delay prediction
C. A deterministic method that determines the longest sequence of
dependent activities affecting project duration
The Critical Path Method identifies the sequence of activities with
zero float that directly determines the project completion time,
making it essential for schedule control.
2. What is the primary purpose of float (slack) in a construction
schedule?
A. To increase project costs for contingency planning
B. To represent allowable delay without affecting successor activities
or project completion
C. To define contractual penalties for delay
D. To eliminate dependencies between activities
, B. To represent allowable delay without affecting successor activities
or project completion
Float provides scheduling flexibility by indicating how long an
activity can be delayed without impacting the critical path or project
end date.
3. In Primavera P6 or similar scheduling software, what does a baseline
schedule represent?
A. The most recently updated schedule reflecting current progress
B. The contractually approved original plan used for performance
comparison
C. A schedule used only for resource allocation
D. A temporary schedule used during design development
B. The contractually approved original plan used for performance
comparison
A baseline schedule is the approved reference point used to measure
progress, delays, and deviations throughout the project lifecycle.
4. What is the main difference between a Gantt chart and a network
diagram?
A. Gantt charts show costs, while network diagrams show only labor
B. Gantt charts are graphical time bars, while network diagrams show
activity relationships and logic flow
C. Gantt charts are used only for small projects
D. Network diagrams cannot show dependencies
B. Gantt charts are graphical time bars, while network diagrams
show activity relationships and logic flow
Gantt charts visually represent time, whereas network diagrams
emphasize task dependencies and sequencing.
5. What does “lag” represent in construction scheduling?
A. A reduction in project cost due to efficiency
B. A mandatory waiting period between two activities
C. The total project float
D. A delay caused by resource shortages
B. A mandatory waiting period between two activities
Lag introduces a required delay between dependent tasks without
affecting their logical relationship.
, 6. Which scheduling constraint would most likely restrict early start dates
of an activity?
A. As Late As Possible constraint
B. Start No Earlier Than constraint
C. Finish No Later Than constraint
D. Mandatory Finish constraint
B. Start No Earlier Than constraint
This constraint prevents an activity from beginning before a specified
date regardless of predecessor completion.
7. What is resource leveling primarily used for in construction
scheduling?
A. Reducing project scope to meet deadlines
B. Adjusting activity timing to resolve resource over-allocation
C. Increasing critical path duration
D. Eliminating all non-critical activities
B. Adjusting activity timing to resolve resource over-allocation
Resource leveling smooths demand by adjusting start and finish
dates to match available resources.
8. Which of the following best describes a predecessor activity?
A. An activity that occurs after another task
B. An activity that has no dependencies
C. An activity that must be completed before another activity can start
D. An activity unrelated to project sequencing
C. An activity that must be completed before another activity can
start
Predecessors establish logical sequencing by requiring completion
before successor tasks begin.
9. What does negative float indicate in a construction schedule?
A. The project is ahead of schedule
B. The schedule has no dependencies
C. The project is behind the required finish date
D. All activities are on the critical path
C. The project is behind the required finish date
Negative float indicates that the project cannot meet imposed
deadlines without corrective action.
