Own your estimates.
Own your AI.
The only construction platform where everything — cost database, AI inference, satellite intelligence, field ops — runs on your server. 55,000 CWICR positions. No subscription. No cloud. No data leaving your jurisdiction.
One platform, every workflow.
Hierarchical bill of quantities with 55,719 CWICR positions and real-time cost calculation.
11 regional markets. Labour, materials, equipment breakdowns. Qdrant-powered semantic search.
Upload DXF/PDF drawings. AI extracts quantities and maps them to verified cost positions.
Seven things they don't have.
Enterprise estimation tools charge €25k/year and still can't do this. ZRO Site ships every one of these capabilities in a single self-hostable platform.
Sovereign local AI
All AI inference runs on your own server via Ollama. Zero data leaves your infrastructure. No third-party API calls, no token metering, no vendor lock-in.
Satellite site intelligence
Copernicus Sentinel-2 imagery analysed by on-premise vision models. Monitor construction sites from orbit without sending data to external services.
Photo-to-estimate
Upload construction site photos. LLaVA vision model identifies materials, quantities, and conditions — generates cost estimates directly from imagery.
Executive copilot
Four specialist modes — daily brief, cost-risk analysis, estimate review, project executive — all powered by your local Ollama instance.
Integrated field operations
Daily logs, crew assignments, site photos, purchase orders, field reports — all in one platform. No separate apps, no data silos.
Document intelligence
PaddleOCR and MinerU extract structured data from scanned plans, invoices, and specifications. Process documents without cloud OCR services.
Swiss data residency
Self-host in Switzerland or any jurisdiction. Full compliance with nFADP and GDPR. Your construction data never crosses borders you don't control.
Everything you need to estimate.

Construction estimation is broken.
The industry relies on spreadsheets riddled with formula errors, or enterprise SaaS platforms that cost €25k/year and lock your data in someone else's cloud. ZRO Site is the third option: open-source, self-hostable, AI-powered.
A project by ZRO Lab.
ZRO Site is part of the ZRO Lab ecosystem — sovereign software for the construction industry, engineered in Geneva.

11 regional markets. 55,719 positions.
Verified CWICR cost data for construction markets worldwide. Every position includes labour, materials, equipment, and overhead.
Real cost data, not estimates.
Concrete foundation C30/37
Steel reinforcement B500B
Timber frame softwood
Granular cost breakdowns.
Every work item decomposes into labour, materials, equipment, and overhead. Costs are region-specific and updated from market data. Semantic search via Qdrant lets you find positions by description, not just codes.
