CPII Quality Assurance 2 — Questions and Answers
Question 1: What is the primary purpose of a Quality Assurance (QA) plan in public infrastructure projects?
- To establish procedures ensuring work meets specified requirements (Correct answer)
- To document contractor payment schedules
- To track project budget expenditures
- To assign liability for construction defects
Correct answer: To establish procedures ensuring work meets specified requirements
A QA plan establishes systematic procedures and responsibilities to ensure all work conforms to contract specifications and standards.
Question 2: Which sampling method involves selecting every nth item from a production lot?
- Random sampling
- Systematic sampling (Correct answer)
- Stratified sampling
- Cluster sampling
Correct answer: Systematic sampling
Systematic sampling selects every nth item at a fixed interval, making it practical for continuous production processes like asphalt paving.
Question 3: A concrete cylinder that fails a compressive strength test at 28 days should trigger which immediate action?
- Remove all concrete placed on that day immediately
- Notify the engineer and evaluate the situation per contract specifications (Correct answer)
- Accept the concrete if visual inspection appears satisfactory
- Retest the same cylinder to verify results
Correct answer: Notify the engineer and evaluate the situation per contract specifications
A failing cylinder test requires immediate notification to the engineer and evaluation per contract specifications before any corrective action is decided.
Question 4: What does the term 'hold point' mean in a quality assurance inspection process?
- A location where work pauses due to weather
- A mandatory inspection stop where work cannot proceed without approval (Correct answer)
- A point where contractor submits payment application
- A location marked for future rework
Correct answer: A mandatory inspection stop where work cannot proceed without approval
A hold point is a mandatory stop in the construction process where an inspector must verify and approve work before the contractor can proceed.
Question 5: When inspecting reinforcing steel placement, what tolerance is typically allowed for cover over main reinforcement in a bridge deck?
- +/- 1/4 inch
- +/- 3/8 inch (Correct answer)
- +/- 1/2 inch
- +/- 1 inch
Correct answer: +/- 3/8 inch
AASHTO and ACI standards typically allow +/- 3/8 inch tolerance for cover over main reinforcement in bridge decks.
Question 6: What is the purpose of a pre-construction conference from a quality assurance perspective?
- To finalize contract pricing and payment terms
- To establish QA roles, responsibilities, and communication protocols before work begins (Correct answer)
- To conduct baseline environmental sampling
- To submit all required insurance certificates
Correct answer: To establish QA roles, responsibilities, and communication protocols before work begins
Pre-construction conferences establish QA roles, inspection hold points, submittal procedures, and communication channels before any work begins.
Question 7: Which document records the inspector's daily observations, test results, and notable events on a construction project?
- Request for Information (RFI)
- Daily Field Report (DFR) (Correct answer)
- Submittal Register
- Non-Conformance Report (NCR)
Correct answer: Daily Field Report (DFR)
The Daily Field Report (DFR) is the primary document where inspectors record all observations, tests, weather, equipment, and workforce activity each day.
