Example inspection data table
This sample shows realistic daily inspection numbers and weights. You can load these values into the calculator using the “Load example” button.
| Category | Total | Done | NA | Critical | Critical done | Weight |
|---|---|---|---|---|---|---|
| Safety | 25 | 22 | 1 | 6 | 6 | 3 |
| Quality | 15 | 12 | 1 | 2 | 2 | 2 |
| Environmental | 10 | 8 | 0 | 1 | 1 | 1 |
| Equipment | 10 | 10 | 1 | 1 | 0 | 2 |
Formula used
- Scorable items = Total items − Not applicable items (when exclusions are enabled).
- Completion % = (Completed ÷ Scorable) × 100.
- Weighted % = Σ(Category completion % × Weight) ÷ Σ(Weight).
- Points % uses a multiplier for critical items, plus optional partial credit.
- Critical completion % = (Critical done ÷ Critical total) × 100.
Tip: If critical completion is below 100%, treat the inspection as high priority even when overall completion looks strong.

Inspection Checklist Completion Article
This calculator is designed for supervisors, HSE staff, and quality leads who want visibility into inspection follow‑through. It summarizes scorable items, open items, and critical closure, then assigns a status using your target and caution thresholds. Use it to standardize reporting locations.
1) Purpose of completion scoring
Inspections generate findings, but closure drives risk reduction. A completion score converts your walk results into one number that managers can review daily, compare across crews, and escalate when performance drops.
2) Typical checklist sizes and throughput
Construction walkdowns commonly include 40 to 80 items. If your list has 60 items and 3 are not applicable, scorable items become 57. Closing 52 items yields 52 ÷ 57 = 91.2% completion.
3) NA handling and data integrity
Marking items NA is valid when work is out of scope, such as hot work controls on a day with no cutting. Excluding NA keeps the score honest and avoids punishing teams for activities that did not occur.
4) Critical items as leading indicators
Critical checks protect against severe outcomes: fall protection, lockout verification, scaffold tagging, and excavation protections. Track critical completion separately. An overall score above 90% is not reassuring when critical closure is below 100%.
5) Category breakdown for targeted action
Grouping items into Safety, Quality, Environmental, and Equipment clarifies where gaps sit. A category view also prevents “average masking,” where one strong area hides a weak area that needs a focused corrective plan.
6) Weighted scoring for priority alignment
Weights let you reflect project priorities. A common setup is Safety weight 3, Quality 2, Environmental 1, and Equipment 2. Weighted scoring increases the influence of high risk categories while still tracking minor topics.
7) Thresholds and performance bands
Set a target score that represents acceptable readiness, often 90 to 97% depending on phase. Add a caution band, such as 85%, to flag teams for coaching before they fall behind and open items accumulate.
8) Reporting, trends, and audit support
Exported CSV files support dashboards, pivot tables, and weekly KPIs. PDF summaries work for meetings and record attachments. When inspections are consistent, trend lines show whether open items are shrinking and whether closeout discipline is improving.
For best results, update numbers immediately after each walk, verify closures in the field, and keep category definitions stable. Over time, the score becomes a leading KPI that supports proactive planning, not just after‑the‑fact documentation.
FAQs
1) What if completed items exceed scorable items?
The calculator caps completed values to the scorable total after NA handling, preventing results above 100% and keeping exports consistent.
2) When should I use Overall totals mode?
Use it for quick snapshots or small checklists when categories are unnecessary, such as a short punch list or a single-trade walk.
3) How do category weights change the score?
Weights increase or decrease the influence of each category’s completion percentage in the weighted score, aligning results with project priorities.
4) What does points mode do differently?
It values critical closures more using a multiplier and can add partial credit for items that are largely complete but awaiting verification.
5) Is critical completion expected to be 100%?
Usually yes. Any open critical control should trigger immediate action and a follow-up check, even when the overall score looks strong.
6) How often should I export CSV or PDF reports?
Export after each formal inspection and at least weekly for trends. Frequent exports improve audit readiness and simplify progress reviews.
7) Can I compare crews using different checklists?
You can, if rules stay consistent. Keep similar scope, handle NA items the same way, and avoid changing thresholds mid-project.
