Claude Code + Revit/DWG/IFC: AI Agent Builds Quantity Takeoff and Dashboards From One Sentence
26 March 2026

⚡️ AI agents are rewriting the rules of construction business

Download Google Antigravity or Claude Code (it is better to use it as a plugin for VS Code). Select the folder with the AI instructions and provide a description of your task or some of your personal information. Finally, type “Automate the process” (or simply say it via voice command in Google Antigravity).

Why this is important for construction -for years, our industry has been at an impasse:

🌚 Expensive proprietary software
🌚 Manual data entry
🌚 Knowledge locked in people's heads
🌚 Vendor lock-in everywhere

AI agents like Claude Code, Antigravity, OpenCode, and Kilo Code are breaking through this impasse.

Here's how it actually works:
1⃣ You give the agent a folder with documentation and examples (download the repositories below as examples ⬇)
2⃣ The AI agent (Antigravity, Claude Code, or others) reads and understands the context
3⃣ You describe what you need in simple language

✨ The agent creates the automation
That's it. No programming required 🤌🏼

What we share for free with instructions for AI agents - at DataDrivenConstruction, we have published years of work as open source:
📥 Construction database (over 55,000 work items, 9 languages)
Resources, work standards, pricing structures – ready for use by AI.
github.com/datadrivenconstruction/OpenConstructionEstimate-DDC-CWICR

📥 CAD/BIM data pipelines
Automatically convert and extract data from Revit, IFC, DWG, and DGN.
github.com/datadrivenconstruction/cad2data-Revit-IFC-DWG-DGN-pipeline-with-conversion-validation-qto

What you can automate with it:
▶ Match elements with price and resource databases
▶ Extract quantities from drawings and models
▶ Create cost estimates from CAD (BIM) data
▶ Create 4D-7D schedules and reports

The real change: In 2026, the competitive advantage will not lie in having the best software. It will be about having the following:
👉🏼 Well-structured data
👉🏼 Clear instructions for AI agents
👉🏼 Willingness to experiment

The old economy needed programmers and IT departments.
The new economy needs people who can explain what they want.

If you can describe your wor kflow in words - you can automate it.
If you know of a process that is difficult or almost impossible to automate using similar methods, please write a comment or send me a private message. I will be happy to look into it with you 🙋‍♂
