CFB Project Planning & Scheduling 2

Question 1

A field builder discovers that a subcontractor's task has a total float of zero days. What does this indicate?

Accepted Answer

The task is on the critical path

Answer

Zero total float means any delay to that task will directly delay the project completion date, placing it on the critical path.

Question 2

When preparing a resource-loaded schedule, what is the PRIMARY purpose of resource leveling?

Accepted Answer

To smooth resource demand and avoid over-allocation peaks

Answer

Resource leveling redistributes work to eliminate over-allocation by shifting non-critical tasks within their float, smoothing the demand curve.

Question 3

A project schedule baseline is BEST described as:

Accepted Answer

The approved version of the schedule used to measure performance

Answer

The schedule baseline is the formally approved plan against which actual performance is measured throughout project execution.

Question 4

Which scheduling technique uses three time estimates—optimistic, pessimistic, and most likely—to account for uncertainty?

Accepted Answer

Program Evaluation and Review Technique (PERT)

Answer

PERT uses three-point estimates and weighted averages to calculate expected activity durations under uncertainty.

Question 5

In a field construction project, a 'look-ahead schedule' typically covers what time horizon?

Accepted Answer

The next 3 to 6 weeks of planned work

Answer

Look-ahead schedules (typically 3–6 weeks) focus near-term crews, materials, and equipment needs to keep field work on track.
