Benchmarks

2026 Construction Drawing Issue Benchmarks

Topic-by-discipline cohort comparisons with aggregate project counts, finding counts, assigned severity, methodology, and limitations.

  • 120 aggregate cohorts
  • 15 issue topics
  • 8 discipline groups

Browse drawing issues by topic

Each topic summary compares the same disclosed title-term group across eight discipline cohorts, with key findings, severity, FAQs, methodology, and links to the underlying benchmark pages.

Methodology and privacy

The research distinguishes platform totals, project-level counts, and structured public records. Each report discloses which sample supports each metric so larger context numbers are not mistaken for downloadable row-level data.

Public downloads contain aggregate fields only. They exclude customer names, project names, addresses, drawings, account identities, project identifiers, and finding text.

Frequently asked questions

What research does InspectMind publish?

The library includes the Construction Drawing Error Index, 120 aggregate issue benchmarks across 15 topics and 8 discipline groups, and machine-readable CSV and JSON downloads.

Can the research datasets be downloaded?

Yes. Both research collections provide free aggregate CSV and JSON files with their source window, methodology, and limitations documented on the corresponding report page.

Do the research files contain customer or project information?

No. The aggregate downloads exclude customer names, project names, addresses, drawings, account identities, project identifiers, and finding text.

Do the benchmark counts represent construction defect rates?

No. The counts describe potential findings surfaced during InspectMind reviews. Categories can overlap, and project scope, document size, design stage, and reviewer validation vary, so the data must not be treated as prevalence, defect rates, or discipline quality rankings.

What source period do the issue benchmarks cover?

The published benchmark source window runs from 2026-03-21 through 2026-09-16. Each report explains its own source population and filtering rules.
