Drawing intelligence
What we build for construction teams
Seven solutions built on the same foundation: models that read construction drawings the way an experienced estimator or reviewer does, and show their work.

- Annotated overlay to check against the sheet
- Usually within 2 business days, no call needed
- NDA available before you share anything
Who it's for
Built for the people who read drawings all day
Each pipeline is scoped to one team's real output: a takeoff sheet, a findings register, or data for a product.
Estimators and preconstruction
Quantities, symbol counts and wall lengths pulled from plan sets, each value traceable to its source on the drawing.Home builders
Takeoff parameters from floor plans and door and window schedules, filled into your own spreadsheet template.Plan reviewers and code consultants
Door widths, clearances and fire-rated doors checked against code rules, with findings flagged for a human to approve.PropTech and construction software teams
Floor plan data (rooms, walls, doors, dimensions) delivered as structured output your product can build on.
In practice
From drawing set to decisions
Symbol counts and quantities for estimating
- Counts per room, sheet and symbol type
- Low-confidence symbols flagged for review
- Exports to your estimating template

Plan review with code citations
- ADA, FHA, IBC and NFPA checks
- Door schedules matched for fire ratings
- Reviewer approves before anything is issued

Engineering drawing review for manufacturers
- Extraction, validation and approval kept separate
- Findings keep sheet, revision and rule references
- Approved results exported to reports, PLM or ERP

Our approach
Why a general chatbot can't do your takeoff
Vision-language models like GPT-4o and Gemini struggle with the spatial layout of high-resolution construction drawings. They miss symbols, misread rotated dimension text and guess at counts. We use a pipeline where each model does one job well, and every output can be checked against the drawing.
- Stage 1
Read the geometry
Vector parsing for DXF files, and segmentation models that trace walls and room boundaries on PDFs and scans.Walls, rooms and dimensions - Stage 2
Detect symbols and read text
Object detectors for doors, windows and fixtures, and OCR built for rotated blueprint text and schedules.Tags, symbols and schedule rows - Stage 3
Apply your rules
Takeoff formulas, cost templates or code requirements run on the structured data, with an LLM used only where reasoning helps.Quantities or findings - Stage 4
Keep a human in the loop
Results come with an annotated overlay and source references, so your team reviews findings instead of redoing the work.Approved, traceable results

How floor plan AI works
- AI-Powered Floor Plan Analysis: Automating Takeoffs and InsightsThis article explores how Artificial Intelligence is revolutionizing construction estimating through automated floor plan analysis, detailing the hybrid AI pipelines required to extract geometry and text.
- What is the Best AI Model for Floor Plan Analysis?Wall segmentation, door detection, OCR text matching—no single model does it all. We review the best AI models for architectural drawings, comparing U-Net, YOLO, and Vision Transformers.
- Why GPT-4V and Gemini Hallucinate on Floor Plans (And What to Use Instead)We put GPT-4o and Gemini 1.5/2.0 to the test on high-resolution construction blueprints. Here is why vision-language models struggle with spatial layouts and how a hybrid AI pipeline solves it.
- Automating Quantity Takeoffs: How AI Extracts and Counts SymbolsEstimators spend hours manually counting windows, doors, and electrical symbols on blueprints. Here is how AI automates symbol extraction and compiles instant takeoff reports.
- Read Between the Lines: Solving Rotated Text & OCR in BlueprintsStandard OCR models fail when text runs vertically or rotates to follow wall lines. Here is how Intelligent OCR (I-OCR) reads blueprints with 99.9% accuracy.
- AI-Powered Floor Plan Analysis for Property Valuation: Automated Blueprint Intelligence & Custom AVMsAI-powered floor plan analysis transforms raw architectural drawings into actionable spatial data, enabling faster, more accurate property valuation. Learn how computer vision and OCR convert blueprints into structured JSON for custom AVMs.
Takeoffs and estimating
- Automating Takeoffs for Home Builders with AI: From Floor Plan to Spreadsheet in SecondsResidential construction estimating starts with a manual takeoff: extracting dozens of parameters from floor plans and schedules. AI cuts this to seconds with over 98% accuracy. Here's how AxcelerateAI turns drawings into structured, audit-ready data for home builders.
- AI Drywall & Material Estimating: Automating Quantity TakeoffsDrywall, flooring, concrete—estimating materials from 2D blueprints is slow and prone to errors. Here is how AI automates wall lengths and area calculations.
- AI-Powered Ornamental Metal Takeoffs: Automating Division 05 Estimating from Construction DrawingsAutomate Division 05 ornamental metal takeoffs from architectural PDF drawing sets. Learn how AxcelerateAI combines CV symbol detection, scale calibration, I-OCR, and agentic cross-document reasoning to measure railings, stairs, and decorative metals in seconds with >98% accuracy.
Plan review and compliance
- Automating Building Code Compliance with AI Floor Plan AnalysisArchitects spend hours manually checking blueprints against ADA, FHA, IBC, and NFPA codes. AI-powered plan analysis automates this entirely — scanning for door widths, corridor clearances, wheelchair turning radii, and egress dimensions with >98% accuracy. Here's how the technology works and what it delivers.
- Automated Fire-Rated Door Detection & Compliance: How AI Reads, Audits, and Certifies Egress Doors on Floor PlansAutomatically detect and verify fire-rated doors in your floor plans. AI scans architectural drawings, reads door tags, matches schedules, and checks against NFPA 80/IBC codes for full compliance — eliminating hours of manual audit work.
- AI Engineering Drawing Review: A Practical Guide to Technical Data Package AutomationAI engineering drawing review combines document extraction, computer vision, and validation rules to identify information that needs an engineer's attention. A useful system returns traceable findings while keeping approval with the engineering team.

PDF plan sheets and architectural drawing sets, DXF exports, and door and window schedules. When a DXF is available, we read the vector geometry directly for exact lengths and areas; otherwise we analyze the PDF. For scan-to-BIM projects, we also work with point cloud laser scans. Every pipeline is custom-built, so if your drawings come out of another CAD or BIM tool, we add that format during scoping.
Structured data for each sheet, such as rooms, walls, doors, symbols and dimensions, plus an annotated overlay so you can check the results. For takeoffs, we fill your own spreadsheet template, and each value links back to the page, layer or schedule it came from.
General vision-language models struggle with spatial layouts on high-resolution construction drawings and tend to hallucinate counts and dimensions. We split the problem instead: segmentation models for walls, detectors for symbols, OCR built for rotated blueprint text, and an LLM only on top of the structured result.
Share one plan sheet through the form on this page. We send back the extracted data and an annotated overlay, usually within 2 business days. No call is needed.
Yes. We build the pipeline around your workflow, whether that means filling a cost template, syncing quantities to your estimating system, or returning structured output to your own application.
Yes. We sign an NDA with every client, and the pipeline can run inside your own cloud account or on your own servers. See our sovereign AI and security pages for deployment options.
