Find anything across every site
Ask in plain language and get a cited answer in seconds, pulled from drawings, RFIs, contracts and field notes across all your sites.
How it works
Construction docs aren't blog posts. We built the retrieval, the reasoning, and the routing to match.
Every answer points to the exact document and page. The only kind a site team can act on.
A drawing is superseded, not replaced. The old sheet is still in somebody's inbox. Every answer names the revision it came from, and flags a newer one the day it lands.
Lemmatization and embeddings tuned for mixed-language corpora. Works the same across the languages your project documents are written in, and answers come back in whichever language you ask.
Org and project scoping, four-level RBAC, and a full audit trail of every query and change.
What it's worth
Real examples of Stoa already in use on live construction sites, and what changed once it was.

3 weeks to 2 days
to find and prove a claim
Stoa checks the work against the owner's requirements to find the claims worth making, then pulls the evidence from correspondence, site diaries and drawing revisions.

70% less
time spent on first drafts
Generate first-draft RFIs, memos and meeting minutes grounded in your own project documents. Ready to review instead of written from scratch.

flagging of clashes and delays
Stoa Automations flag conflicting instructions, open RFIs and schedule risks automatically, surfacing problems before they reach the site.

In practice
Six roles on one project. What each of them asks for, and what comes back.
Site manager
“Which revision of the 3rd-floor slab drawing is current, and what changed?”
The current sheet, the one it superseded, and the difference between them, each cited to the page.
Design coordinator
“Does the new HVAC layout clash with anything in the structural set?”
Conflicts surfaced across disciplines, with both source documents attached to the finding.
Project engineer
“Draft the RFI for the missing penetration detail.”
A drafted RFI with the relevant contract clauses and drawings already pulled in.
Project manager
“What changed on the project last week that I should know about?”
Quiet revisions, new decisions, and open items, each routed to whoever owns that scope.
Site engineer
“What fire rating is required for the corridor partitions on level 2?”
The requirement, the specification it comes from, and the drawing that shows the build-up.
Quantity surveyor
“Which variations were approved since the last valuation?”
A dated list with the approval record behind each one, ready to take into the valuation.
Why it matters
Same project. Same documents. Less digging. More deciding.
Hours lost across M-Files, OneDrive, Drive, Teams, and email.
Find any answer in seconds, with the page cited.
Revision conflicts surface only when they're already expensive.
Issues caught before they hit the site.
Status compiled by hand. Tasks lost in email.
Tasks and reports come from the project itself.
Data & safety
Project documents are the most sensitive material on a construction site. Here is exactly how they are handled.
No migration and no cleanup project. Connect a source and the graph builds itself.
Stored and processed in the EU, never used to train the models, and deleted within 30 days on request.
Two business days from first call to a working project.
