CPI CPI Quality Control & Inspection 2 — Questions and Answers
Question 1: What is the purpose of maintaining as-built documentation during a CPI project?
- To create marketing materials for the installer's portfolio
- To record actual installed conditions that differ from original design drawings (Correct answer)
- To track employee performance reviews
- To document material costs for tax purposes
Correct answer: To record actual installed conditions that differ from original design drawings
As-built documentation records all field changes from the original design, creating an accurate record of what was actually installed for future maintenance and reference.
Question 2: A CPI installer notices a hairline crack in a structural substrate before installation. What is the correct course of action?
- Cover it with adhesive and proceed
- Document the crack and notify the project manager or engineer before proceeding (Correct answer)
- Apply caulk and continue the installation
- Ignore it if the crack is less than 1/8 inch wide
Correct answer: Document the crack and notify the project manager or engineer before proceeding
Structural defects must be documented and reported to the responsible engineer or project manager before installation proceeds to prevent safety issues or installation failure.
Question 3: What does 'tolerance' mean in the context of installation quality control?
- The maximum allowable deviation from a specified dimension or condition (Correct answer)
- The minimum number of workers required on a job
- The acceptable delay before starting a project
- The extra material ordered as waste allowance
Correct answer: The maximum allowable deviation from a specified dimension or condition
Tolerance defines the permissible range of deviation from a specified measurement or condition, such as ±1/8 inch for floor levelness.
Question 4: When performing a water test on a newly installed rooftop waterproofing system, what does a successful result confirm?
- The membrane meets fire resistance requirements
- No leaks exist through the installed membrane or flashings under ponded water conditions (Correct answer)
- The membrane is properly bonded to the deck
- The insulation below meets the specified R-value
Correct answer: No leaks exist through the installed membrane or flashings under ponded water conditions
A flood or water test confirms the installed waterproofing membrane and all flashings are leak-free by ponding water for a specified duration.
Question 5: Which quality assurance practice involves a third-party inspector verifying installation work independent of the contractor?
- Self-certification
- Special inspection (Correct answer)
- Value engineering
- Shop drawing review
Correct answer: Special inspection
Special inspection involves a third-party, owner-engaged inspector who independently verifies critical installation work meets code and specification requirements.
Question 6: What information should be recorded in a field quality control log during installation?
- Only items that fail inspection
- Date, inspector name, work observed, materials checked, test results, and any deficiencies noted (Correct answer)
- Only the names of workers present each day
- Only the final sign-off after all work is complete
Correct answer: Date, inspector name, work observed, materials checked, test results, and any deficiencies noted
A complete field QC log captures date, inspector identity, scope of work observed, material batch numbers, test results, and any noted deficiencies for each inspection event.
