Quality Control and Work Completion
Quality control and work completion tests whether you can inspect against criteria, record results, correct nonconformities, and hand over work that is complete and protected.
Core rules
- Know the acceptance criteria: dimensions, tolerances, alignment, finish, and function.
- Use checklists and hold points; do not cover work before the required inspection.
- Inspect with the correct tools: level, plumb, tape, square, moisture meter, feeler gauge where applicable.
- Record location, defect, cause, action, and re-inspection result.
- Separate nonconforming work and correct it before punch listing.
- Complete punch items, clean the area, protect finishes, and compile turnover records.
Worked example
Before drywall, you inspect a framed wall. You check stud spacing, plumb, plate alignment, header size, blocking, and nailing. You find one stud out of plumb and mark it. The carpenter corrects it, you re-inspect, and only then sign the inspection request. Reasoning: once covered, correction costs much more and the record is lost.
Traps
- Signing an inspection request before the check.
- Recording “okay” without location or measurement.
- Accepting a defect because “the finisher will cover it.”
- Closing a punch item without re-inspection.
The exam favors evidence: measurements, dates, names, and re-checks. A complete handover includes cleaned work, protected finishes, and records that show each hold point was released properly.
