CST Schedule Variance & Delay Analysis 3

Question 1

Which recovery schedule technique adds resources to critical activities to compress the schedule while minimizing additional cost?

Accepted Answer

Crashing

Answer

Crashing adds resources (overtime, additional crew) to critical path activities to reduce duration, with a focus on the lowest cost-slope activities first.

Question 2

A contractor submits a Time Impact Analysis (TIA) for an owner-caused delay. The TIA must demonstrate that the delay event:

Accepted Answer

Impacted the critical path and extended the contract completion date

Answer

A valid TIA must show that the delay event pushed activities onto or further along the critical path, resulting in a later project completion date.

Question 3

Schedule Variance at Completion (SV at completion) is zero when:

Accepted Answer

The project finishes exactly on its planned completion date

Answer

Schedule Variance at completion is zero only when the project actually completes on the planned finish date, meaning all planned work was completed as scheduled.

Question 4

The 'critical path collapse' (Collapsed As-Built) method in delay analysis works by:

Accepted Answer

Removing all delay events from the as-built schedule to calculate the theoretical shortest completion

Answer

The Collapsed As-Built method removes delays from the as-built schedule to reveal what the completion date would have been without those delays.

Question 5

If the SPI = 1.15 and the project is 60% complete by schedule, what does this suggest?

Accepted Answer

The project is performing 15% more efficiently than planned and is likely ahead of schedule

Answer

An SPI of 1.15 means the team is earning $1.15 of planned value for every $1.00 worth of scheduled time, indicating ahead-of-schedule performance.
