AIC Construction Scheduling & Time Management Flashcards

Under the AIC Body of Knowledge, which document formally establishes the project baseline schedule?

Answer: The schedule approved by the owner and incorporated into the contract

The baseline schedule is the owner-approved, contract-incorporated schedule against which all progress and changes are measured.

A contractor receives a change order that adds 30 days to the project duration. What schedule document should be formally updated?

Answer: The baseline schedule via a time impact analysis

Contract time changes require a formal time impact analysis and revision to the baseline schedule to reflect the updated project duration.

Which scheduling software is most commonly used on large US commercial construction projects?

Answer: Primavera P6

Primavera P6 is the industry-standard CPM scheduling software widely required by owners and GCs on large commercial and infrastructure projects.

What is the purpose of a Time Impact Analysis (TIA) in construction scheduling?

Answer: To quantify how a change event affects the project completion date

A TIA inserts a change event into the schedule at the time it occurred to demonstrate its impact on the critical path and project completion date.

When a construction activity has Total Float = 0, it means:

Answer: Any delay to that activity will delay the project completion date

Zero total float identifies a critical activity — any delay to it directly extends the overall project finish date.

Which scheduling technique incorporates probability distributions to account for uncertainty in activity durations?

Answer: PERT / Monte Carlo simulation

PERT and Monte Carlo simulation use statistical distributions of activity durations to estimate the probability of meeting a given project completion date.
