A field builder is asked to identify 'free float' for an activity. Free float is defined as:
Answer: The amount an activity can be delayed without delaying the early start of any successor
Free float is the delay an individual activity can absorb without impacting the early start of its immediate successor activities.
During field operations, an activity is marked 'out-of-sequence' in the schedule. What does this mean?
Answer: Work has started or finished without the predecessor being completed as planned
Out-of-sequence progress occurs when work proceeds contrary to the planned predecessor-successor logic, which can distort schedule calculations.
What is the primary purpose of a project schedule 'narrative' or 'basis of schedule' document?
Answer: To explain the assumptions, constraints, and methodology used to develop the schedule
The basis of schedule documents the planning assumptions, constraints, sequencing logic, and methodology so reviewers understand how durations and sequences were established.
A field builder's project has a Planned Value (PV) of $500,000 and an Earned Value (EV) of $450,000. What is the Schedule Variance (SV)?
Answer: -$50,000
Schedule Variance = EV – PV = $450,000 – $500,000 = –$50,000, indicating the project is $50,000 behind its planned schedule progress.
Which type of project dependency is defined by a contract, legal requirement, or physical constraint of the work—not by the project team's preference?
Answer: Mandatory dependency (hard logic)
Mandatory dependencies (hard logic) are inherent to the nature of the work and cannot be altered, such as curing concrete before applying loads.
A field builder needs to accelerate a project that is behind schedule. Before crashing, the FIRST action should be to:
Answer: Identify the critical path activities where compression will reduce project duration
Compressing non-critical activities has no effect on project duration; crashing must target critical path activities to reduce the overall schedule.
In project scheduling, what does 'Start-to-Start' (SS) dependency with a 5-day lag mean?
Answer: The successor task can start 5 days after the predecessor task starts
A Start-to-Start with 5-day lag means the successor activity cannot begin until 5 days after the predecessor activity has started.
