| Scenario | Total | NA | Compliant | Noncompliant | Critical | Major | Minor | Method | Typical Outcome |
|---|---|---|---|---|---|---|---|---|---|
| Routine weekly walkthrough | 50 | 5 | 43 | 2 | 0 | 1 | 2 | Compliance | High score with minor corrective actions |
| High-risk phase inspection | 70 | 10 | 52 | 8 | 2 | 3 | 5 | Weighted | Moderate score; prioritize critical controls |
| Restart after incident review | 40 | 0 | 24 | 16 | 3 | 4 | 6 | Weighted | Low score; pause and correct hazards |
Step 1: Applicable items
Applicable = Total Items − Not Applicable
Method A: Compliance percentage score
Compliance % = (Compliant ÷ Applicable) × 100
Score = (Compliance % ÷ 100) × Max Score
Method B: Weighted deductions score
Deductions = (Critical × Wc) + (Major × Wm) + (Minor × Wn)
Optional Noncompliance Deduction = Noncompliant Items × Penalty
Score = Max Score − (Deductions + Optional Noncompliance Deduction)
Rating uses the normalized 0–100 score: Excellent ≥95, Good ≥85, Fair ≥70, otherwise Poor.
Safety audits turn observations into measurable performance. A score helps compare crews, subcontractors, and phases of work using the same rules. In many programs, weekly audits cover 30–100 checklist items and target scores above 85/100 to confirm controls are working.
This calculator supports two common approaches: compliance percentage and severity-weighted deductions. Compliance scoring rewards completion of requirements. Weighted scoring emphasizes risk by subtracting points for critical, major, and minor findings, which aligns better with high-risk activities like lifting, excavation, and energized work.
Many construction checklists group items into areas such as PPE, housekeeping, access/egress, fall protection, electrical, tools, lifting, traffic control, and permits. When a section does not apply, mark it as NA so the “applicable” denominator stays accurate and the score remains fair.
Programs often set action thresholds, for example: Excellent ≥95, Good 85–94, Fair 70–84, and Poor <70. Pair thresholds with response times, such as closing critical issues within 24–48 hours and documenting completion evidence (photos, permits, or re-inspection notes).
A useful starting point is 10 points per critical, 5 per major, and 2 per minor finding. Example: 2 critical + 3 major + 4 minor equals 2×10 + 3×5 + 4×2 = 43 points deducted from a 100-point maximum. Adjust weights to match your risk matrix.
Single scores can be noisy, so track rolling averages (e.g., last 4 audits). Also track “findings per 100 applicable items.” If findings/100 rises from 6 to 12, conditions are degrading even if the score still looks “Good.” Use the CSV export to chart trends.
Strong programs measure closeout effectiveness, not just quantity. Record owner, due date, and verification step. If repeat findings appear in consecutive audits, escalate controls: refresher training, pre-task planning, supervisor coaching, or equipment changes. Document what changed and re-audit.
Use the PDF summary for daily huddles and weekly leadership reviews. Highlight top three hazards, overdue corrective actions, and any critical findings. When a score is Poor, consider pausing high-risk tasks until controls are implemented and verified through a follow-up audit.
Consistent scoring improves accountability, visibility, and safety performance across the entire project.
Use compliance scoring for routine checklists where each item has similar risk. Use weighted scoring when severity matters, such as fall protection, lifting, excavation, and electrical. Weighted methods better highlight low-frequency, high-consequence hazards.
A critical finding is an uncontrolled hazard with immediate serious injury potential, such as missing fall protection at height, unprotected excavation, energized exposure, or unsafe lifting setup. Classify using your site risk matrix and stop-work rules.
NA items should be excluded from scoring because they were not required for that audit. Removing NA items keeps the denominator accurate and prevents penalizing crews for activities that were not performed or conditions that did not exist.
Start with a simple scale (e.g., 10/5/2 for critical/major/minor) and adjust after reviewing 4–8 weeks of audits. Weights should reflect your risk matrix and encourage rapid closure of the highest-risk items.
Averages can hide recurring hazards. Track repeat findings, overdue actions, and findings per 100 applicable items. If repeats persist, strengthen controls: revise procedures, add supervision, improve planning, or change tools/equipment.
Many sites perform weekly formal audits plus daily supervisor walkthroughs. Increase frequency during high-risk phases, after incidents, or when new crews mobilize. The best schedule matches task risk, workforce size, and project complexity.
Share the score, rating, critical findings, overdue corrective actions, and the top recurring hazards. Include photos or verification notes for closed items. Leadership should see both performance (score) and control effectiveness (closeout quality).
Audit consistently, correct hazards early, and protect every worker.
