A project reports SV = -$15,000 and SPI = 0.82. What do these metrics collectively indicate?
Answer: The project is behind schedule and completing less work than planned per dollar spent
A negative SV and SPI below 1.0 both confirm the project is behind schedule, completing only 82 cents of planned work per dollar of time elapsed.
Which delay analysis technique overlays the as-planned schedule against the as-built schedule to identify where delays originated?
Answer: As-Planned vs. As-Built comparison
The As-Planned vs. As-Built comparison graphically overlays both schedules to identify divergence points and delay sources.
During a delay claim, the opposing party argues that your critical path delay was concurrent with their excusable delay. The most likely result is:
Answer: Time extension may be granted but no additional compensation for the overlapping period
Concurrent delays typically result in a time extension for the overlapping period, but additional costs are generally not awarded to either party during that window.
A schedule shows Total Float = 0 and Free Float = 0 for Activity X. If Activity X is delayed by 5 days, what is the most likely impact?
Answer: The project finish date is delayed by 5 days
Zero total float means the activity is on the critical path, so any delay directly extends the project finish date by the same duration.
The Earned Schedule (ES) method improves upon traditional EVM schedule metrics by:
Answer: Converting SV from dollars to days, providing a time-based schedule variance
Earned Schedule converts the schedule variance from a cost-unit measure to actual time units (days/weeks), making schedule slippage directly interpretable.
A project manager notices that the SPI has been consistently below 1.0 for six weeks but the critical path has not changed. The most likely explanation is:
Answer: Only non-critical activities are behind schedule, consuming float
Non-critical activities can be behind schedule and reduce earned value without shifting the critical path, since their delays absorb available float.
In a construction delay claim, 'pacing delays' refer to:
Answer: A contractor intentionally slowing non-critical work to match a known critical path delay caused by another party
Pacing delays occur when a contractor slows otherwise non-critical work in response to an owner-caused critical delay, to avoid inefficient out-of-sequence work.
