AI vs. manual plan review: comparing construction document findings
For architects, engineers, and construction teams, this comparison examines how Groundbook AI findings and manual plan-check comments support construction document QA/QC, interdisciplinary coordination, and permit resubmittals.
Compare the condition, the evidence, and the requested action. Groundbook findings and manual plan-check comments can identify shared concerns while expressing them at different levels of detail. Connecting those observations gives the project team a practical basis for coordinating revisions and documenting responses.
Plan review and construction document QA/QC
Construction document quality assurance and quality control (QA/QC) includes checking drawings, schedules, specifications, and calculations for completeness and coordination. Within that process, AI-assisted plan review can identify document discrepancies and organize findings for the design team to evaluate.
Manual plan review can include design-team reviews and permit plan check. In permit plan check, a plans examiner reviews the submitted construction documents against applicable requirements and issues comments for the team to address. This article compares recorded findings and requested corrections.

About this comparison
This article draws on selected findings from an AI-assisted review and a manual plan-check record.
The focus is how the review records describe conditions and support corrective action. This is an editorial comparison by Groundbook, not a performance benchmark or a claim that either review method identifies every possible condition.
What the comparison found
Groundbook's review record contained findings that directly matched 9 manual plan-check comments and markups, with 8 further entries showing partial overlap. It also documented 100 additional distinct review observations not explicitly stated in the manual summary, after consolidating repeated and closely overlapping records.
| Result | Count | What it means |
|---|---|---|
| Manual plan-check comments and markups with direct matches | 9 | The same condition and requested correction are represented in Groundbook's findings. |
| Manual plan-check comments and markups with partial overlap | 8 | Groundbook describes a related condition or part of a broader comment; these are counted separately from direct matches. |
| Additional Groundbook observation groups | 100 | Distinct technical or documentation observations without a specific counterpart in the manual summary. |
How the counts were determined
The direct-match count includes 7 numbered comments and 2 unnumbered highlights. Each manual comment or markup is counted once, even when it corresponds to several Groundbook records. Repeated manual comments remain separate entries in that count.
For the additional-observation count, records describing the same condition or a common correction were consolidated. This includes repeated labels, repeated specification wording, and a shared sheet-index correction. Groups with direct or partial counterparts were excluded from the additional count. A general request to demonstrate code compliance was not treated as a match to every code-related observation.
These counts use two units: manual plan-check comments and markups for overlap, and consolidated Groundbook observation groups for additional findings. Additional observations include technical coordination, code-reference, and drafting items. They describe the available review records; the responsible design professionals determine which observations require correction. The comparison does not establish which reviewer identified a condition first or a detection rate.
Shared concerns, different levels of detail
A manual comment may request a coordinated correction across several documents. A Groundbook finding may identify the specific note, schedule, or detail that contributes to the same concern. Matching the underlying condition helps the team combine the supporting evidence into a clear response.
| Topic | Manual plan-check comment | Groundbook finding | Coordinated action |
|---|---|---|---|
| Stair geometry | Requests demonstration that a typical stair detail meets the applicable criteria. | Identifies a dimensional inconsistency between stair details. | Reconcile the details and document the applicable design criteria. |
| Fire-resistance-rated assemblies | Requests identification of rated separations and supporting assembly listings. | Identifies locations where assembly ratings or listings need clarification. | Coordinate the required ratings, assembly designations, and construction details. |
| Energy-compliance scope | Requests that compliance documentation reflect the described construction scope. | Identifies a discrepancy between the documented scope and the classification used in the energy documentation. | Align the compliance documents with the scope of work. |
| Sheet-index coordination | Requests an accurate index of the submitted documents. | Identifies documents not represented in the index. | Reconcile the index with the issued drawing set. |
| Code-reference consistency | Requests correction of an outdated reference. | Identifies inconsistent code-edition references within the documents. | Confirm the governing edition and coordinate affected references. |
| Drawing titles and scales | Requests clarification of drawing identification and scale. | Identifies conflicting titles and unresolved scale labels. | Correct the labels so the drawing's purpose and scale are clear. |
These examples describe shared concerns. A related topic is not automatically an identical finding: the location, evidence, and requested correction determine whether comments should be combined.
How AI plan review supports interdisciplinary coordination
The reviewed Groundbook findings also illustrate several forms of document checking that can support the team's response process.
Specifications and details
Groundbook identified inconsistencies between system specifications and related details. Comparing those documents helps the team determine which requirements need clarification and where revisions should be coordinated.
Coordination between disciplines
Groundbook connected mechanical equipment information with structural support documentation. This type of finding gives the responsible engineers a defined coordination question: do the equipment requirements, mounting details, and supporting structure describe a consistent design?
Energy documentation and scheduled assemblies
Groundbook identified differences between modeled assembly properties and information in architectural documents. The resulting review action is to reconcile the model inputs, schedules, and specifications.
Manual plan-check comments provide corresponding requests for clarification, supporting documentation, and demonstrated compliance. Together, the records give the team observations to evaluate and actions to track through the revision process.
Compare findings by their purpose
Useful review language distinguishes the nature of the observation:
- Coordination discrepancy: two or more documents describe a condition differently.
- Missing or unclear information: a drawing, schedule, or detail needs clarification to communicate the design.
- Potential code-compliance issue: a documented condition warrants evaluation against the applicable requirement.
- Supporting-document request: calculations, product data, assembly listings, or other evidence are needed to support the response.
This vocabulary gives each finding an actionable purpose. It also keeps document observations distinct from final compliance determinations.
For a meaningful comparison, consider the condition addressed, the supporting evidence, and the revision needed. The number of entries alone does not measure review quality: one comment may cover several actions, while another may describe one discrete condition. This article makes no numerical claims about detection rates, review speed, cost savings, or permit outcomes.
Prepare a response to comments and coordinated resubmittal
- Establish the review basis. Identify the drawing revision, reference documents, and applicable requirements.
- Connect related findings. Group comments that concern the same condition while preserving distinct requested actions.
- Assign responsibility. Identify the lead discipline and any coordination required with other consultants.
- Document the response. Prepare a response to comments that records each clarification or correction and references the revised sheets, details, or supporting calculations.
- Verify the revised documents. Check that the response is reflected consistently in the affected drawings, schedules, specifications, and calculations.
Groundbook supports this workflow by organizing document findings with references for review. Responsible design professionals evaluate and coordinate the response, and the authority having jurisdiction (AHJ) makes the applicable permit-compliance determinations.

Frequently asked questions
What is the difference between AI plan review and manual plan review?
AI-assisted plan review uses software to identify document discrepancies and organize supporting references. Manual plan review applies a professional reviewer’s judgment to the documents and applicable requirements. Teams can compare the resulting findings by condition, evidence, and requested correction.
How many manual plan-check comments and markups were also represented in Groundbook?
The comparison identified 9 direct matches and 8 partial overlaps. The direct matches include 7 numbered comments and 2 unnumbered highlights. Partial overlaps are reported separately.
How many additional observations did Groundbook document?
After consolidating repeated and closely overlapping records, the comparison identified 100 additional distinct observation groups not explicitly stated in the manual summary. These include technical and documentation observations, with the response to each finding determined through the review process.
How do Groundbook findings relate to manual plan-check comments?
They can address the same underlying condition at different levels of detail. Matching the condition, evidence, and requested action helps the team prepare a coordinated response.
What should a team compare?
Compare the purpose and supporting evidence of each finding, the documents affected, and the action needed to resolve it. Entry counts alone do not provide a like-for-like measure of review quality.
How is customer privacy protected in this article?
The examples are generalized at the review-topic level. Project names, locations, filenames, record identifiers, construction quantities, dimensions, and private source materials are omitted. Only aggregate comparison counts are reported.
Who determines the response to a finding?
The responsible professionals evaluate the finding, coordinate the design response, and document revisions. The authority having jurisdiction makes the applicable permit-compliance determinations.
