What is the significance of torque specifications when tightening structural bolts during an installation?
Answer: Proper torque ensures the correct clamping force is achieved without over-stressing the bolt
Torque specifications ensure structural bolts develop the correct clamping force, preventing joint slippage or bolt failure from under- or over-tightening.
A CPI inspector uses a feeler gauge during a floor tile installation. What is being measured?
Answer: The grout joint width or lippage (height difference) between adjacent tiles
A feeler gauge measures grout joint widths or lippage (height variation between adjacent tiles) to verify they meet specification tolerances.
What does 'minimum 95% adhesive contact' mean in a tile installation specification?
Answer: At least 95% of the tile's back surface must be in contact with the mortar bed
95% adhesive contact means at least 95% of each tile's back surface area must be embedded in mortar, ensuring adequate bond strength and support.
When should an installer request a formal nonconformance report (NCR) be issued on a project?
Answer: When a material or installation does not meet specified requirements and cannot be immediately corrected
A nonconformance report is issued when work or materials deviate from specified requirements, documenting the issue and required corrective action.
What is the correct sequence for a proper inspection workflow on a CPI installation project?
Answer: Inspect substrate, document conditions, install, final inspection and closeout
Proper QC workflow begins with substrate inspection and documentation, proceeds through installation, and concludes with final inspection and closeout documentation.
A CPI installer discovers that installed work was covered before a required inspection was completed. What is the appropriate action?
Answer: Notify the project manager immediately; the work may need to be uncovered for inspection
Work covered before a required inspection must be reported to the project manager, as the authority having jurisdiction may require it to be uncovered and inspected.
