Turn field observations into a dependable inspection score for every crew today. Adjust severity weights, compare sites, and download records for compliance reviews fast.
Tip: Keep weights consistent across projects to compare performance fairly.
| Scenario | Total | Minor | Major | Critical | Other | Bonus | Weights (Mi/Ma/Cr/O) | Expected Score |
|---|---|---|---|---|---|---|---|---|
| Routine daily walk | 60 | 3 | 1 | 0 | 2 | 0 | 1 / 3 / 7 / 2 | ~80% (Medium) |
| High-risk correction day | 80 | 2 | 0 | 1 | 3 | 2 | 1 / 3 / 7 / 2 | ~69% (High) |
| Strong performance | 50 | 1 | 0 | 0 | 1 | 3 | 1 / 3 / 7 / 2 | ~98% (Low) |
1) Passed checkpoints
Passed = Total − (Minor + Major + Critical + Other)
2) Penalty points
Penalty = (Minor × Wminor) + (Major × Wmajor) + (Critical × Wcritical) + (Other × Wother)
3) Score percent
Score% = clamp( ((Passed + Bonus − Penalty) ÷ Total) × 100, 0, 100 )
A consistent inspection score converts observations into an actionable performance signal. It helps supervisors compare areas, track trends by week, and defend decisions during audits. When teams see the same scoring logic every day, corrective actions become faster and more measurable.
Many site walk checklists range from 40 to 120 checkpoints, depending on trade density and risk. Common categories include PPE, fall protection, access and egress, electrical controls, lifting and rigging, housekeeping, mobile equipment, excavations, and permits. Use your actual list count for accurate percentages.
Minor issues are quick fixes with low injury potential, such as missing labels or small housekeeping gaps. Major issues raise the likelihood of serious harm, like damaged guards or unsafe access. Critical issues indicate imminent danger, such as unprotected edges or collapse risk requiring immediate control.
This calculator applies severity weights to emphasize high-risk conditions. A practical starting point is 1 for minor, 3 for major, 7 for critical, and 2 for other failures. For example, one critical issue produces a much larger penalty than several minor issues, which aligns scores with true exposure.
Grades summarize performance for reporting: 90–100 is A, 80–89 is B, 70–79 is C, 60–69 is D, and below 60 is F. Risk level is elevated by any critical issue, multiple major issues, or low scores. Use the risk label to prioritize leadership attention.
Bonus points reward verified proactive actions, such as completing toolbox talks, adding compliant barricades, or closing high-risk items ahead of schedule. Keep bonus conservative and documented. A good practice is limiting bonus to a small fraction of total checkpoints so it cannot mask serious findings.
Teams often target 85% or higher for routine work and 90%+ for mature programs. If scores fall below 70%, treat it as a leading indicator of rising incident probability. Track top recurring issues, assign owners, set closeout dates, and confirm fixes during follow-up inspections.
Exported CSV and PDF reports support trend charts, weekly dashboards, and compliance evidence. Record project area, inspector name, and concise notes to explain context. Consistent documentation strengthens accountability, helps identify training needs, and supports corrective action verification across all crews.
Use the number of items on your inspection checklist for that walk. If you add or remove checklist items, update the total so scores remain comparable across days and areas.
Minor issues are low severity and quickly corrected. Major issues present significant hazard potential or clear noncompliance. Align categories with your safety program definitions to keep scoring consistent.
Critical findings represent imminent danger. A single critical condition can outweigh strong performance elsewhere because it can cause serious injury immediately, so the risk indicator stays high.
Yes. Adjust weights to match your organization’s policy or local risk profile. Keep the same weights for comparisons, and document any changes so historical trends remain meaningful.
Use this for failures that do not fit your severity labels, such as paperwork gaps, missing signage, or incomplete permits. You can increase or reduce the “other weight” as needed.
Apply bonus only for verified proactive actions and keep it small. Bonus should never offset serious hazards. If you record bonus, describe the action in notes for transparency.
High-activity sites often benefit from daily walks, while stable phases may use weekly inspections plus targeted checks. Increase frequency after major changes, new crews, or recurring high-risk findings.
Measure safety performance, fix gaps, and protect every worker.
