CDT Quality Control & Inspection 1 — Questions and Answers
Question 1: What is the primary purpose of quality control inspections?
- To verify work meets specified standards and identify deficiencies early (Correct answer)
- To delay project completion
- To find reasons to penalize workers
- To satisfy insurance requirements only
Correct answer: To verify work meets specified standards and identify deficiencies early
Quality control inspections verify compliance with standards and identify deficiencies early when corrections are less costly and disruptive.
Question 2: How should material specifications be verified upon delivery?
- Compare delivery against purchase order specifications and inspect for damage (Correct answer)
- Accept all deliveries without inspection
- Only check quantities, not quality
- Inspect only if the supplier is new
Correct answer: Compare delivery against purchase order specifications and inspect for damage
Verifying materials against specifications and inspecting for damage upon delivery prevents non-conforming or damaged materials from being incorporated into work.
Question 3: What should be done when materials do not meet specifications?
- Reject the materials, document the non-conformance, and notify the supplier (Correct answer)
- Use them if they seem close enough
- Modify the specifications to match the materials
- Store them for future projects
Correct answer: Reject the materials, document the non-conformance, and notify the supplier
Non-conforming materials must be rejected with documented non-conformance reports and supplier notification to maintain quality standards and contractual compliance.
Question 4: Why is proper material storage important?
- It preserves material properties and prevents degradation or contamination (Correct answer)
- It only matters for aesthetic appearance
- It is only important for expensive materials
- It has no effect on material performance
Correct answer: It preserves material properties and prevents degradation or contamination
Proper storage preserves material properties, prevents degradation from environmental exposure, and ensures materials perform as specified when installed.
Question 5: What documentation should accompany quality control activities?
- Test reports, inspection checklists, non-conformance reports, and corrective actions (Correct answer)
- Only photographs of completed work
- A simple pass/fail notation
- Documentation is only needed for final inspection
Correct answer: Test reports, inspection checklists, non-conformance reports, and corrective actions
Comprehensive QC documentation provides evidence of compliance, supports traceability, and creates records needed for audits and warranty claims.
Question 6: How should equipment be selected for specific tasks?
- Based on task requirements, capacity ratings, and safety certifications (Correct answer)
- Whichever equipment is available
- Based on lowest rental cost
- By worker preference only
Correct answer: Based on task requirements, capacity ratings, and safety certifications
Equipment selection based on task requirements, capacity ratings, and safety certifications ensures safe operation and effective task completion.
