Crashing a schedule involves:
Answer: Adding resources to critical path activities to shorten their duration
Schedule crashing shortens the project duration by adding resources (overtime, additional crews) to critical path activities, typically at increased cost.
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?
Answer: 4 days
Total float = LS – ES = 9 – 5 = 4 days (or equivalently LF – EF = 16 – 12 = 4 days).
What scheduling deliverable is typically required by owners within 30 days of Notice to Proceed?
Answer: A detailed CPM schedule showing all activities, durations, and logic ties
Most construction contracts require a fully detailed CPM schedule within 30 days of NTP to establish the baseline for project monitoring and payment.
Which of the following best describes 'free float'?
Answer: The amount of time an activity can be delayed without delaying the early start of any successor
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.
A schedule that has been loaded with cost information for each activity is called a:
Answer: Cost-loaded schedule
A cost-loaded schedule assigns dollar values to each activity, enabling the generation of S-curves and progress payment applications tied to schedule performance.
What is the primary purpose of a Time Impact Analysis (TIA) on a construction project?
Answer: To quantify the schedule delay resulting from a specific change or unforeseen event
A Time Impact Analysis evaluates the prospective or retrospective effect of a change, delay, or differing site condition on the project schedule to support time extension claims.
Which of the following is a leading indicator of schedule performance rather than a lagging indicator?
Answer: Constraint removal rate in the 3-week lookahead
The rate at which near-term constraints are removed (a leading indicator) predicts future schedule performance, whereas SPI and percent complete measure what has already happened.
