AIC Construction Scheduling & Time Management Flashcards

Which of the following is a key input when developing a project master schedule?

Answer: Scope of work and contract milestones

The scope of work and contract milestones define what must be accomplished and by when, forming the backbone of any master schedule.

A construction project's Schedule Performance Index (SPI) is 0.85. This means the project is:

Answer: Progressing at 85% of the planned rate

SPI = EV/PV; an SPI of 0.85 means the project is accomplishing only 85% of the planned work progress rate.

Resource leveling in project scheduling is used to:

Answer: Smooth resource demand by shifting non-critical activities within their float

Resource leveling shifts non-critical activities within available float to smooth peaks and valleys in resource demand.

What is 'crashing' in the context of construction schedule compression?

Answer: Adding resources to critical path activities to shorten their duration

Schedule crashing involves adding resources (workers, equipment, shifts) to critical path tasks to reduce their durations at added cost.

Fast-tracking a construction schedule means:

Answer: Performing activities in parallel that would normally be done sequentially

Fast-tracking overlaps phases or activities that are normally sequential, compressing the schedule without necessarily adding cost.

Which type of activity relationship specifies that Activity B cannot start until Activity A has been completed?

Answer: Finish-to-Start (FS)

Finish-to-Start is the most common dependency type, requiring the predecessor activity to finish before the successor can begin.
