Which scheduling method uses a network diagram where each node represents an activity and arrows show dependencies?
Answer: Activity-on-Node (AON)
Activity-on-Node (AON), also called Precedence Diagramming Method (PDM), places activities in nodes with arrows showing logical relationships.
The Critical Path in a project schedule is defined as the sequence of activities that:
Answer: Has zero total float and determines project duration
The critical path is the longest path through the network with zero total float, meaning any delay on it directly extends the project finish date.
What does 'Total Float' represent in Critical Path Method (CPM) scheduling?
Answer: The amount of time an activity can be delayed without delaying the project completion
Total float is the amount of time an activity can be delayed from its early start without delaying the project's overall finish date.
In CPM scheduling, the Early Start (ES) of an activity is calculated by:
Answer: Taking the maximum Early Finish of all predecessor activities
The Early Start of an activity equals the maximum Early Finish among all its predecessors, ensuring all preceding work is complete before starting.
Which type of logical relationship in Precedence Diagramming means 'Activity B cannot start until Activity A finishes'?
Answer: Finish-to-Start (FS)
Finish-to-Start (FS) is the most common relationship, requiring the predecessor to finish before the successor can begin.
What is the primary purpose of a Gantt Chart in construction scheduling?
Answer: Visually represent the project timeline with bars showing activity durations
A Gantt chart is a bar chart that visually shows each activity's start and end dates on a timeline, making the schedule easy to read and communicate.
When applying resource leveling to a construction schedule, the primary goal is to:
Answer: Smooth resource demand to avoid peaks and valleys
Resource leveling adjusts activity start dates (within float) to create a more uniform resource demand, reducing costly crew mobilization/demobilization cycles.
