Estimators and preconstruction
Quantities, symbol counts and wall lengths pulled from plan sets, each value traceable to its source on the drawing.
Construction and AEC
AI for construction and AEC: floor plans, takeoffs and plan review
Estimators, home builders, plan reviewers and PropTech teams all lose hours reading drawings by hand. We build custom computer vision and OCR pipelines that turn plan sets into quantities, compliance findings and structured data you can check and trust.
- PDF and DXF drawings
- Every value traceable to the sheet
- Runs in your cloud if needed

Capabilities
What we build for construction teams
Floor plan and spatial analysis
Room segmentation, object detection and OCR that turn PDF floor plans and blueprints into structured spatial data: rooms, walls, doors, symbols and dimensions.
Explore AI floor plan analysisQuantity takeoff and estimating
Automated material estimates from blueprint sheets, including drywall linear footage, concrete volume and symbol counts, synced to your cost templates.
Explore AI quantity takeoffPlan review and code compliance
Rule engines on top of floor plan data to check door widths, corridor clearances, turning radii and fire-rated doors against ADA, FHA, IBC and NFPA requirements.
Read how automated code compliance worksScan-to-BIM and digital twins
Conversion of legacy 2D floor plans, blueprints and point cloud laser scans into semantic BIM models ready for Autodesk Revit and CAD software.
Explore AI scan-to-BIMOur 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 hybrid pipeline where each model does one job well, and every output can be checked against the drawing.
- 1
Read the geometry
Vector parsing for DXF files, and segmentation models that trace walls and room boundaries on PDFs.
- 2
Detect symbols and read text
Object detectors for doors, windows and fixtures, and OCR built for rotated blueprint text and schedules.
- 3
Apply your rules
Takeoff formulas, cost templates or code requirements run on the structured data, with an LLM used only where reasoning helps.
- 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.

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.
FAQ
Questions from construction teams
What drawing files can you work with?
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.
What do we get back?
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.
Why not just use GPT-4o or Gemini on our drawings?
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.
How does the free floor plan analysis work?
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.
Can the output feed our estimating or review software?
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.
Can our drawings stay private?
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.
