✅ Quality Inspection Playbook
Standardized inspection process for work-in-place. Catch defects before they're covered up and avoid expensive rework that kills your budget and schedule.
Why Quality Inspections Matter
| Impact | Without Inspections | With Inspections |
|---|---|---|
| Rework costs | 5–15% of project cost | under 2% of project cost |
| Punch list length | 500+ items at substantial completion | Manageable list, no surprises |
| Schedule | Rework delays completion | First-time quality = on-time delivery |
| Client satisfaction | Callbacks, complaints, disputes | Smooth closeout, repeat business |
| Warranty claims | Expensive post-completion fixes | Issues caught and fixed during construction |
Roles and Responsibilities
| Role | Responsibilities |
|---|---|
| Foreman | Self-inspect own crew's work before requesting formal inspection |
| Superintendent | Conduct formal quality inspections, document findings, verify corrections |
| Project Manager | Review inspection reports, monitor trends, escalate systemic issues |
| Project Engineer | Maintain inspection logs, schedule third-party inspections, track deficiencies |
| Subcontractors | Self-inspect before requesting acceptance, correct deficiencies per timeline |
| Third-Party Inspector | Independent inspections per contract (structural, mechanical, electrical, fire) |
Types of Inspections
| Type | When | Who Inspects | Purpose |
|---|---|---|---|
| Self-inspection | Before requesting formal inspection | Foreman / crew | Catch obvious issues before anyone else sees them |
| In-progress inspection | During work | Superintendent | Verify work is on track, catch issues early |
| Hold point inspection | At defined milestones (before cover-up) | Superintendent + A/E or inspector | Formal verification before proceeding |
| Third-party / special | Per contract or code | Licensed inspector, testing agency | Code compliance, structural, MEP, fire |
| Pre-punch inspection | Before owner walk | Superintendent | Internal quality check before formal punch list |
| Final inspection | At substantial completion | Owner / A/E | Accept work as substantially complete |
Step-by-Step Process
Step 1: Define Hold Points
At project start, identify every point where work must be inspected before it gets covered up or the next phase begins.
Common hold points:
| Trade | Hold Point | What Gets Covered |
|---|---|---|
| Earthwork | Subgrade inspection | Buried under foundation |
| Concrete | Pre-pour: rebar, embeds, formwork | Buried in concrete |
| Concrete | Post-pour: finish, elevation, curing | Covered by flooring/finishes |
| Structural steel | Connections, torque, welds | Covered by fireproofing/finishes |
| Framing | Rough framing before sheathing | Covered by sheathing |
| MEP rough-in | Rough plumbing, electrical, HVAC before close-up | Covered by drywall |
| Waterproofing | Below-grade waterproofing before backfill | Buried underground |
| Insulation | Insulation before drywall | Covered by drywall |
| Fire stopping | Fire-rated penetration sealing | Concealed in walls/ceilings |
| Roofing | Each layer before the next is applied | Covered by subsequent layers |
Never Cover Without Inspection
Covering uninspected work is one of the most expensive mistakes in construction. Tearing out drywall to inspect rough plumbing costs 10x what the inspection would have cost.
Step 2: Self-Inspection (Before Formal Inspection)
The foreman inspects their own crew's work before calling for formal inspection:
Self-inspection checklist approach:
- Review the contract drawings and specs for the area
- Walk the area with a checklist (see examples below)
- Fix anything you find before calling for inspection
- Take photos showing the work is ready
- Notify superintendent that the area is ready for formal inspection
Why self-inspect first?
- Avoids embarrassment — getting failed by the inspector
- Saves time — inspector doesn't have to come back
- Builds quality culture — crews take pride in first-time acceptance
Step 3: Formal Inspection
The superintendent (or designated inspector) walks the area:
- Bring the right documents — Drawings, specs, approved submittals, checklist
- Systematic walk — Go area by area, item by item — don't just scan
- Check against drawings — Verify locations, sizes, types, spacing
- Check against specs — Verify materials, methods, workmanship standards
- Check against submittals — Verify approved products were actually installed
- Test functionality — Where applicable (doors open/close, fixtures operate, slopes drain)
- Photograph — Document both conforming and nonconforming work
- Document findings — Note every deficiency with location, description, and photo
Step 4: Document Findings
For each deficiency found:
| Field | Details |
|---|---|
| Location | Building, floor, room, grid — specific enough to find it |
| Description | What's wrong — clear and specific |
| Severity | Critical (must fix before proceeding), Major (must fix before close-up), Minor (cosmetic, can fix later) |
| Reference | Drawing/spec section that defines the requirement |
| Photo | Labeled photo showing the deficiency |
| Responsible party | Who needs to fix it |
| Due date | When the correction is due |
Deficiency severity levels:
| Level | Definition | Timeline |
|---|---|---|
| Critical | Safety issue or structural deficiency — work must stop in this area | Fix immediately, re-inspect before any further work |
| Major | Does not meet drawings/specs — must be fixed before cover-up | Fix within 48 hours, re-inspect before proceeding |
| Minor | Cosmetic or minor workmanship issue | Fix before pre-punch walk |
Step 5: Correction and Re-Inspection
- Notify the responsible party — Written notice with deficiency details
- Set a correction deadline — Based on severity and schedule
- Responsible party makes corrections — Fix the deficiency
- Re-inspect — Verify the correction meets requirements
- Document closure — Note the deficiency as corrected, with date and photo
- Release the hold — Allow subsequent work to proceed
Inspection Checklists by Trade
Concrete — Pre-Pour Inspection
- Forms aligned per drawings (location, dimensions, elevation)
- Forms clean, oiled, and tight (no gaps)
- Rebar size, spacing, and placement per drawings
- Rebar clear cover verified (chairs/spacers in place)
- Rebar tied at all intersections
- Lap splices correct length and location
- Embedded items placed per drawings (anchor bolts, sleeves, plates)
- Blockouts in place (MEP penetrations, floor drains)
- Waterstop installed (if required)
- Grade and elevation verified (survey)
- Formwork adequately braced/shored
- Concrete mix design approved per submittal
- Testing agency notified (cylinders, slump, air)
Framing — Before Sheathing
- Layout matches drawings (wall locations, dimensions)
- Stud size and spacing per drawings
- Headers, cripples, and king studs per details
- Hold-down and anchor bolt locations verified
- Blocking for fixtures, cabinets, equipment in place
- Fire blocking installed where required
- Plumb and straight within tolerance
- Bearing connections match structural drawings
- All penetrations sleeved or blocked
MEP Rough-In — Before Close-Up
- Pipe/conduit routing matches drawings
- Proper sizing per drawings and specs
- Supports and hangers at required intervals
- Correct materials per submittal (pipe type, wire gauge)
- Firestopping at all rated penetrations
- Pressure testing complete (plumbing — record results)
- Insulation on pipes/ducts per spec
- Electrical boxes at correct heights
- Grounding and bonding complete
- Access panels provided where required
Common Mistakes
| Mistake | Consequence | Fix |
|---|---|---|
| Inspecting too late | Work is already covered — must tear out to inspect | Define hold points at project start, enforce them |
| Checklist not specific to the work | Miss items unique to this project | Customize checklists for each project/trade |
| Not documenting deficiencies | "It was fine when I looked at it" — no proof | Written report with photos for every inspection |
| No re-inspection | Deficiency reported but never verified as fixed | Always re-inspect corrections before proceeding |
| Foreman skips self-inspection | Superintendent finds obvious errors — wastes everyone's time | Make self-inspection a mandatory step before formal inspection |
Metrics
| Metric | Target | Frequency |
|---|---|---|
| Hold point inspections completed | 100% before cover-up | Per hold point |
| First-time acceptance rate | over 85% | Monthly |
| Open deficiencies | Zero critical, under 10 major | Weekly |
| Deficiency correction time | Critical under 24 hrs, Major under 48 hrs | Per occurrence |
| Rework cost as % of project | under 2% | Monthly |
