CPI CPI Quality Control & Inspection 1 — Questions and Answers
Question 1: What is the purpose of a pre-installation inspection before beginning a CPI installation project?
- To calculate the final invoice amount
- To verify site conditions and substrate suitability before materials are installed (Correct answer)
- To train new crew members on-site
- To document how much material was wasted
Correct answer: To verify site conditions and substrate suitability before materials are installed
A pre-installation inspection confirms that site conditions and substrates meet the requirements for a successful installation before work begins.
Question 2: Which tool is commonly used to verify that a surface is level during an installation inspection?
- Torpedo level or digital level (Correct answer)
- Multimeter
- Stud finder
- Chalk line
Correct answer: Torpedo level or digital level
A torpedo level or digital level measures horizontal or vertical plumb/level on surfaces during installation quality checks.
Question 3: A CPI installer performs a pull test on an anchor. What does this test verify?
- The anchor's color match to the substrate
- The anchor's load-holding capacity in the installed substrate (Correct answer)
- The anchor's electrical conductivity
- The anchor's temperature rating
Correct answer: The anchor's load-holding capacity in the installed substrate
A pull test applies a tensile force to an installed anchor to verify it achieves the required load-holding capacity in the actual substrate.
Question 4: What does a 'punch list' represent at the end of a construction or installation project?
- A list of tools returned to inventory
- A documented list of deficiencies or incomplete items requiring correction before final acceptance (Correct answer)
- A schedule for future maintenance visits
- A list of subcontractors who worked on the project
Correct answer: A documented list of deficiencies or incomplete items requiring correction before final acceptance
A punch list documents all deficiencies, incomplete work, or items not meeting specifications that must be corrected before the owner grants final acceptance.
Question 5: When inspecting a freshly applied sealant bead, which defect indicates improper tooling or insufficient adhesion?
- A smooth concave profile
- Voids, bubbles, or separation at the bond line (Correct answer)
- A uniform width throughout
- A slightly recessed center
Correct answer: Voids, bubbles, or separation at the bond line
Voids, bubbles, or separation at the bond line indicate the sealant was not properly tooled or did not achieve full adhesion to the substrate.
Question 6: Which inspection method uses a moisture meter to check substrate conditions before flooring installation?
- Tensile adhesion testing
- In-situ relative humidity or pin-type moisture testing (Correct answer)
- Thermal imaging scan
- Hardness testing
Correct answer: In-situ relative humidity or pin-type moisture testing
In-situ relative humidity (probe method) or pin-type moisture meters measure moisture levels in concrete or wood substrates before flooring is installed.
