CTB CTB Project Management & Planning 1 — Questions and Answers
Question 1: Which document establishes the scope, schedule, and budget baseline for a track construction project?
- Project charter (Correct answer)
- Work breakdown structure
- Risk register
- Change order log
Correct answer: Project charter
The project charter formally authorizes the project and defines its scope, schedule, and budget baseline.
Question 2: A critical path in a track project schedule represents:
- The longest sequence of dependent tasks that determines project duration (Correct answer)
- The most expensive phase of construction
- The route with the most safety hazards
- The first tasks scheduled after mobilization
Correct answer: The longest sequence of dependent tasks that determines project duration
The critical path is the longest chain of dependent activities; any delay on it directly delays project completion.
Question 3: What is the purpose of a pre-construction meeting on a track project?
- To align all stakeholders on plans, responsibilities, and site protocols before work starts (Correct answer)
- To issue final payment to subcontractors
- To complete the punch list inspection
- To submit as-built drawings to the owner
Correct answer: To align all stakeholders on plans, responsibilities, and site protocols before work starts
A pre-construction meeting ensures all parties understand the project scope, schedule, safety rules, and communication procedures before mobilization.
Question 4: Float (slack) in a project schedule refers to:
- The amount of time an activity can be delayed without delaying the project finish (Correct answer)
- Extra material ordered to cover waste
- Overtime hours budgeted for the crew
- The buffer added to rail delivery lead times
Correct answer: The amount of time an activity can be delayed without delaying the project finish
Float is the flexibility available for non-critical activities before they impact the overall project completion date.
Question 5: Which scheduling method is most commonly used on large track construction projects to identify task dependencies?
- Precedence Diagramming Method (PDM) (Correct answer)
- Trial-and-error estimation
- Simple to-do list
- Alphabetical task ordering
Correct answer: Precedence Diagramming Method (PDM)
PDM (used in CPM scheduling) shows finish-to-start and other logical relationships between activities on large projects.
Question 6: A cost baseline on a track project is best described as:
- The approved time-phased budget used to measure cost performance (Correct answer)
- The contractor's initial bid before negotiations
- The contingency reserve set aside for unknown risks
- The total value of change orders approved to date
Correct answer: The approved time-phased budget used to measure cost performance
The cost baseline is the approved, time-phased budget that serves as a reference for earned value analysis and cost control.
