One platform, every workflow.
From first sketch to final tender — BOQ editing, cost research, AI takeoff, field operations, and copilot analysis in a single self-hosted product.
Full hierarchical bill of quantities backed by 55,000+ verified CWICR positions. Inline editing, real-time totals, PDF and Excel export in one click.
Four analysis modes — daily brief, cost risk, estimate review, executive — all querying your live project data. Fully sovereign, zero external calls.
Upload a site photo. Local AI identifies materials, quantities, and surface conditions and maps the findings to verified cost lines — all on your own server, no cloud.
See it work.
Seven core workflows — from BOQ editing to satellite site analysis. All running on your own infrastructure, no cloud dependencies.
Seven capabilities the incumbents can't match.
Candy, CostX, and Procore cost €15,000–€40,000 per year and lock your data in their cloud. Every capability below ships in ZRO Site today — self-hosted, sovereign, and built for real teams.
Sovereign AI — your hardware, your inference
Every AI call runs on your own server. No Anthropic, no OpenAI, no cloud tokens. Full audit trail per inference. Sovereignty is the default, not an add-on.
Site intelligence from orbit
Copernicus Sentinel-2 satellite imagery pulled and processed entirely on your server. Terrain, vegetation, and site access returned as structured data — no third-party API.
Photo to estimate in one upload
Drop a site photo. The local vision model identifies materials, quantities, and surface conditions and maps the findings directly to verified cost positions.
Copilot in four grounded modes
Daily brief, cost-risk analysis, estimate review, and project executive mode. Each queries your live project data — zero hallucinated numbers, zero external calls.
Talent pool and recruitment
Browse verified workers and teams by trade, availability, rating, and location. See references, request hire, manage your own workforce — all in one platform.
Live material price intelligence
Connect your local suppliers, track current prices per material, and get instant cheapest-source comparison at estimate time. Real prices, not benchmarks.
Everything you need to estimate.

Construction estimation is broken.
The industry pays Candy, CostX, or Bluebeam tens of thousands a year and still ends up back in spreadsheets. ZRO Site is the third option: self-hostable with a single command, with every AI call running on your own hardware.
Trusted by construction professionals.
“ZRO Site cut our estimate cycle from 10 days to 3 and gave procurement a defensible BOQ.”
“We replaced three tools with one. The local processing and audit trail were decisive for our compliance team.”
“The BOQ editor and takeoff workflow finally let us standardize assumptions across projects.”
A project by ZRO Lab.
ZRO Site is one product in the ZRO Lab ecosystem — sovereign software built for construction teams worldwide.
