Countertop Overhang Measurement Qc
This document defines the standard work for verifying countertop overhang dimensions at the final QC stage. Consistent measurement technique prevents field-fit issues, reduces callback rates, and ensures compliance with design specifications and industry standards.
To establish a repeatable, verifiable method for measuring and documenting countertop overhangs (front, side, and bar/peninsula) during the final quality control check. The objective is to eliminate guesswork, reduce installation rework to <5% defect rate, and provide an auditable record of conformance to shop drawings.
This SOP applies to all laminate, solid surface, quartz, and natural stone countertop assemblies fabricated in the shop (Jobsite measuring is covered under SOP-FLD-004). It covers overhang checks for standard base cabinets, islands, breakfast bars, and scribe returns. Applies to QC Technicians, Lead Fabricators, and Installers during final sign-off.
- Use proper lifting techniques and mechanical assistance (suction cups, cranes) when positioning large slabs on the QC table to prevent musculoskeletal injuries or dropped slabs.
- Wear cut-resistant gloves (Level 5 ANSI) when handling raw edges or profiles to avoid lacerations from sharp stone or laminate edges.
- Safety glasses must be worn at all times when measuring, especially around seam areas where debris may be present.
- Ensure the QC inspection table is stable and locked in position before placing any material on the surface.
- Digital Caliper (6″ minimum)
- Stainless Steel Rule (48″)
- CNC Verification Template (if applicable)
- Fabricator Pencil & QC Check Sheet
- Torpedo Level (for confirming substrate flatness)
- Camera for photo documentation (defects/passes)
