CCM Time Management 3 — Questions and Answers
Question 1: Which document establishes the approved project schedule baseline against which progress is measured?
- Project Charter
- Schedule Management Plan
- Baseline Schedule (Correct answer)
- Work Breakdown Structure
Correct answer: Baseline Schedule
The baseline schedule is the formally approved version of the project schedule used to measure and report schedule performance.
Question 2: Activity sequencing in a Precedence Diagramming Method (PDM) network is based on which type of logical relationships?
- Only Finish-to-Start relationships
- Finish-to-Start, Start-to-Start, Finish-to-Finish, and Start-to-Finish (Correct answer)
- Only Start-to-Start and Finish-to-Finish
- Activity on Arrow relationships only
Correct answer: Finish-to-Start, Start-to-Start, Finish-to-Finish, and Start-to-Finish
PDM supports all four logical relationship types (FS, SS, FF, SF), offering more flexibility than the older Arrow Diagramming Method.
Question 3: A construction project is experiencing repeated delays due to subcontractor interference. Which scheduling technique best addresses this by identifying parallel work conflicts?
- Time-location diagram (linear scheduling) (Correct answer)
- Resource leveling
- Critical chain method
- Time-scaled logic diagram
Correct answer: Time-location diagram (linear scheduling)
Time-location diagrams (also called linear schedules or LOB) plot work progress against both time and location, making crew interference conflicts visually apparent.
Question 4: Under the Contract Time provisions of AIA A201, what is the owner's remedy if the contractor fails to achieve Substantial Completion by the contract date?
- Immediate termination of contract
- Assessment of liquidated damages as specified in the contract (Correct answer)
- Mandatory schedule acceleration at owner's cost
- Automatic time extension
Correct answer: Assessment of liquidated damages as specified in the contract
AIA contracts typically allow the owner to assess liquidated damages for each day beyond the contractual Substantial Completion date.
Question 5: Which analysis technique identifies the longest path through a schedule network to determine the minimum project duration?
- Monte Carlo simulation
- Critical Path Analysis (Correct answer)
- Earned Value Analysis
- Trend Analysis
Correct answer: Critical Path Analysis
Critical Path Analysis calculates early and late dates for all activities to identify the longest path, which determines the shortest possible project duration.
Question 6: A construction manager wants to recover 3 weeks of schedule delay at the lowest possible cost. Which approach should be evaluated first?
- Crashing all critical path activities simultaneously
- Fast-tracking by overlapping design and construction phases (Correct answer)
- Reducing project scope
- Increasing the number of work shifts on near-critical activities
Correct answer: Fast-tracking by overlapping design and construction phases
Fast-tracking overlaps activities that were originally planned sequentially, potentially recovering time without incurring direct cost premiums.
Question 7: What is the significance of 'negative float' appearing in a construction schedule?
- The activity has extra time available
- The project completion date has already been missed or is mathematically unachievable (Correct answer)
- The activity is on the critical path
- Resources have been over-allocated
Correct answer: The project completion date has already been missed or is mathematically unachievable
Negative float indicates the project's calculated completion date is later than the required completion date, signaling a schedule deficit that must be addressed.
