GCC Construction Project Management and Planning 3 — Questions and Answers
Question 1: A contractor is managing a project with a $2,000,000 budget and 12-month duration. After month 6, the Schedule Performance Index (SPI) is 0.85. What does this mean?
- The project is 15% over budget
- The project is only accomplishing 85 cents of scheduled work for every dollar of planned work — behind schedule (Correct answer)
- The project is 15% ahead of schedule
- The project cost efficiency is 85%
Correct answer: The project is only accomplishing 85 cents of scheduled work for every dollar of planned work — behind schedule
An SPI below 1.0 means the project is behind schedule, earning only $0.85 of planned value for every $1.00 of scheduled work.
Question 2: Under the Design-Build delivery method, who is responsible for both the design and construction of the project?
- The owner and the architect separately
- A single entity (the design-builder) responsible for both design and construction (Correct answer)
- The construction manager at-risk only
- Multiple prime contractors coordinated by the owner
Correct answer: A single entity (the design-builder) responsible for both design and construction
In Design-Build, a single entity contracts with the owner and is responsible for integrating design and construction under one agreement.
Question 3: Which document issued by the owner's designer provides clarification or supplementary information in response to a contractor's written question during construction?
- Submittal log
- Request for Information (RFI) response / Architect's Supplemental Instruction (ASI) (Correct answer)
- Notice to Proceed (NTP)
- Bid addendum
Correct answer: Request for Information (RFI) response / Architect's Supplemental Instruction (ASI)
An RFI response or Architect's Supplemental Instruction (ASI) is used to clarify design intent without changing the contract price or time.
Question 4: What is the purpose of retainage in a construction contract?
- To provide the contractor a bonus for early completion
- To incentivize subcontractors to bid lower
- To withhold a percentage of progress payments as financial security until work is satisfactorily completed (Correct answer)
- To fund the project contingency reserve
Correct answer: To withhold a percentage of progress payments as financial security until work is satisfactorily completed
Retainage is a percentage (commonly 5-10%) withheld from each progress payment to ensure the contractor completes all work and corrects deficiencies.
Question 5: A project experiences a 30-day delay caused solely by unusually severe weather not anticipated in the contract. The contractor is entitled to:
- Both additional time and additional money
- Additional time only (excusable, non-compensable delay) (Correct answer)
- Additional money only
- Neither time nor money because weather is a contractor risk
Correct answer: Additional time only (excusable, non-compensable delay)
Unusually severe weather typically constitutes an excusable, non-compensable delay — the contractor receives a time extension but no additional compensation.
Question 6: Which document formally transfers responsibility for a construction project from the contractor to the owner upon satisfactory completion?
- Notice to Proceed
- Certificate of Substantial Completion (Correct answer)
- Punch list
- Submittals log
Correct answer: Certificate of Substantial Completion
A Certificate of Substantial Completion marks the point when the project is sufficiently complete for the owner to use it for its intended purpose.
Question 7: When performing project cost estimating, which method is most accurate but requires the most time and detailed information?
- Parametric estimating (cost per square foot)
- Analogous estimating (historical project data)
- Bottom-up estimating (detailed quantity takeoff) (Correct answer)
- Three-point estimating (PERT)
Correct answer: Bottom-up estimating (detailed quantity takeoff)
Bottom-up estimating builds cost from detailed material, labor, and equipment quantities for every work item, producing the most accurate but time-intensive estimate.
