CST Schedule Compression & Acceleration Techniques 3

Question 1

When fast-tracking introduces a start-to-start relationship with a lag, what does the lag represent?

Accepted Answer

The minimum required delay before the successor activity can begin after its predecessor starts

Answer

A lag in a start-to-start relationship defines the minimum waiting period after the predecessor starts before the successor is permitted to begin.

Question 2

When initiating schedule compression, the scheduler should first focus on:

Accepted Answer

Critical path activities that directly drive the project completion date

Answer

Only compressing activities on the critical path reduces the overall project end date; compressing non-critical activities has no effect on project duration.

Question 3

Which metric best indicates that schedule compression efforts are achieving the desired recovery?

Accepted Answer

A Schedule Performance Index (SPI) trending toward or above 1.0

Answer

An SPI trending toward or above 1.0 indicates earned progress is catching up to or exceeding planned progress, confirming recovery.

Question 4

A contractor is 3 weeks behind on a 20-week construction project. Which combination of techniques is most effective for schedule recovery?

Accepted Answer

Fast-tracking with additional resources (crashing) applied to critical path activities

Answer

Combining fast-tracking with crashing on critical path activities addresses both sequencing inefficiencies and resource shortfalls, providing the greatest recovery potential.

Question 5

In a contract environment, when an owner directs a contractor to accelerate the schedule beyond the original contract baseline, the contractor may be entitled to:

Accepted Answer

Additional compensation for the increased costs associated with directed acceleration

Answer

Directed acceleration—where the owner requires the contractor to work faster than contractually planned—may entitle the contractor to additional compensation for incremental costs incurred.
