Question 1

Crashing a schedule involves:

Accepted Answer

Adding resources to critical path activities to shorten their duration

Answer

Schedule crashing shortens the project duration by adding resources (overtime, additional crews) to critical path activities, typically at increased cost.

Question 2

An activity has an Early Start (ES) of Day 5, an Early Finish (EF) of Day 12, a Late Start (LS) of Day 9, and a Late Finish (LF) of Day 16. What is its total float?

Accepted Answer

4 days

Answer

Total float = LS – ES = 9 – 5 = 4 days (or equivalently LF – EF = 16 – 12 = 4 days).

Question 3

What scheduling deliverable is typically required by owners within 30 days of Notice to Proceed?

Accepted Answer

A detailed CPM schedule showing all activities, durations, and logic ties

Answer

Most construction contracts require a fully detailed CPM schedule within 30 days of NTP to establish the baseline for project monitoring and payment.

Question 4

Which of the following best describes 'free float'?

Accepted Answer

The amount of time an activity can be delayed without delaying the early start of any successor

Answer

Free float is the amount an activity can slip without impacting the early start of any immediately following activity, making it a local measure of scheduling flexibility.

Question 5

A schedule that has been loaded with cost information for each activity is called a:

Accepted Answer

Cost-loaded schedule

Answer

A cost-loaded schedule assigns dollar values to each activity, enabling the generation of S-curves and progress payment applications tied to schedule performance.
