Waterfront hotel
Door schedule and separation requirements disagree
Sleeping-unit entry doors opening into an interior lobby were marked unrated, while the surrounding separation called for protected openings.

An AI blueprint reader that reads the whole set
Reading one blueprint is a skill. Reading a set is a different job: the answer to almost any question sits on another sheet, in a schedule, or in the specifications. Groundbook reads the whole set at once, cross-checks the parts that have to agree, and shows you the sheets behind every finding.
Inside Groundbook
From blueprints to findings
Upload the blueprints as PDFs
Add the drawing set plus the documents it has to agree with: specifications, schedules, reports, and your checklists. We read the building codes and amendments that governments publish online, and you can upload a code you’re licensed to use. Native exports, scans, photographs, and hand-drawn sheets all work. Import from Autodesk Construction Cloud (Forma), SharePoint, Google Drive, Box, Dropbox, or Bluebeam Studio, or email the PDFs to the project.
Groundbook reads the set as one connected document
Every sheet is read as a page: title block, legend, symbols, dimension strings, schedule rows, keynotes, and callouts. Those become a project knowledge graph, so a door tag on a plan is linked to its schedule row, its wall type, its detail, and the code section that governs it.
Review findings beside the blueprints
Each finding names the problem, shows the words and shapes it is based on highlighted on every sheet involved, and states the correction. Open it beside the blueprint and decide.
A finding, with its sheets
See both sides of the conflict
This hotel finding connected an entry door on the plan with its schedule row and the separation requirement that governed it. No single blueprint showed the problem. Open the image to inspect the evidence view.
What reading a set involves
Six things a reader has to follow
Reading a blueprint set is six kinds of tracing, each one running from a mark on one sheet to the place that defines it. This is what Groundbook follows, and what the reviewer confirms.
| What is read | Where it is defined | What the reviewer confirms |
|---|---|---|
| Symbols and legends | Legend sheets, abbreviation lists, keynotes, and the symbols used on each discipline’s plans. | Confirm a symbol means the same thing across disciplines. A tag that two consultants define differently is a document question, not a drafting preference. |
| Dimensions and scale | Dimension strings, stated scales, grid lines, and the details they resolve to. | Check the measurement basis before treating two numbers as a conflict. Face of stud, face of finish, and centerline conventions differ by discipline. |
| Schedules and tags | Door, window, room, equipment, and fixture schedules against the tags printed on the plans. | Every tag should resolve to one schedule row, and the row should agree with the plan on size, type, rating, and quantity. |
| Callouts and references | Detail bubbles, section markers, and "see" notes against the sheet index. | A callout that points at a sheet or detail that is not in the set is a finding on its own, no interpretation needed. |
| Specifications | The project manual against the drawing notes, schedules, and details. | Products, ratings, and performance values stated in two places should say the same thing. Where they differ, the contract’s order of precedence decides. |
| Codes and local ordinances | Codes detected from the drawings. We read the building codes and amendments that governments publish online, and licensed model codes, such as the I-Codes, NFPA, and ASME, only where a license allows it. Add or remove codes, or upload a copy you’re licensed to use. | Compliance questions cite the code section beside the sheet, with a link to the source, so the responsible professional can confirm applicability and edition. We never copy or distribute code text. |
From published project reviews
Three questions a single sheet cannot answer
These anonymized findings come from published Groundbook reviews. Each one needed at least two sheets, or a sheet and a reference document, to see at all. They are potential issues for professional verification; final design decisions and completed corrections are not claimed.
Mixed-use residential
Structural and mechanical floor elevations differ
Structural and mechanical plans showed different elevations for the same floor area, creating a cross-discipline coordination question.

A required opening appears in only one discipline
A sump shown in the mechanical/plumbing design was not represented in the corresponding structural slab and footing area.

A blueprint set is only half the package
The drawings say where and how big. The specifications say what and how well, the schedules carry the properties, and the codes set the limits. Upload the drawings, specifications, and schedules together and the review can check them against each other and against the codes that apply. Upload drawings alone and it can only check the drawings against themselves and the codes.
Start with a set your team already knows, so you can compare the findings against the questions you had. Identify the governing issue, note anything deliberately incomplete, and say which documents are references rather than work to be checked.

Questions, answered
FAQs
What is an AI blueprint reader?
Software that reads construction blueprints and reports what it finds. The useful kind reads a whole set rather than one sheet, because most blueprint questions are answered somewhere else in the package. Groundbook reads the set, cross-checks the parts that must agree, and returns findings linked to the exact sheet and location.
Can AI read blueprints accurately?
It can read them well enough to be useful and not well enough to be trusted blindly. Groundbook transcribes what is printed, corrects that transcription against the image, and records anything illegible as unreadable rather than guessing. Every finding shows its evidence so a person can confirm it before acting.
How do I review blueprints with AI?
Create an account, set up a project, and see the exact price before you pay anything. After that, Reviews are priced per page from about $100 per project, $1 per drawing page and $0.25 per reference page. Tools advertised as entirely free generally answer questions about a sheet you upload rather than reviewing a complete set.
What file formats can I upload?
PDFs. Native exports from CAD or BIM read best, and scanned, photographed, and hand-drawn sheets are read as images; see how <a href="/scanned-drawing-review/">scanned and hand-drawn sets</a> are handled. There is no limit on the number of pages in a set.
Is a blueprint the same as a drawing or a plan?
In practice, yes. "Blueprint" is the older name, from the cyanotype process that printed white lines on blue paper, and it stuck as everyday shorthand for construction drawings. Design and construction teams usually say drawings, plans, or the set. A plan specifically means a view from above, so a set contains plans along with sections, elevations, details, and schedules.
