BCM Construction Scheduling and Planning

Question 1

Which scheduling method uses a network diagram where each node represents an activity and arrows show dependencies?

Accepted Answer

Activity-on-Node (AON)

Answer

Activity-on-Node (AON), also called Precedence Diagramming Method (PDM), places activities in nodes with arrows showing logical relationships.

Question 2

The Critical Path in a project schedule is defined as the sequence of activities that:

Accepted Answer

Has zero total float and determines project duration

Answer

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.

Question 3

What does 'Total Float' represent in Critical Path Method (CPM) scheduling?

Accepted Answer

The amount of time an activity can be delayed without delaying the project completion

Answer

Total float is the amount of time an activity can be delayed from its early start without delaying the project's overall finish date.

Question 4

In CPM scheduling, the Early Start (ES) of an activity is calculated by:

Accepted Answer

Taking the maximum Early Finish of all predecessor activities

Answer

The Early Start of an activity equals the maximum Early Finish among all its predecessors, ensuring all preceding work is complete before starting.

Question 5

Which type of logical relationship in Precedence Diagramming means 'Activity B cannot start until Activity A finishes'?

Accepted Answer

Finish-to-Start (FS)

Answer

Finish-to-Start (FS) is the most common relationship, requiring the predecessor to finish before the successor can begin.
