Set the standard.
The state follows.
In daily use across state DOTs, county engineers, and city public works departments.
When your agency adopts digital stationing, every contractor and CEI firm on your projects follows. A common platform, but separate instances, that connects agency, contractor, and CEI teams — with collaboration and sharing on your terms. Standardized documentation tied to a station, captured in real time, defensible anytime.
Built for how DOTs and municipalities actually deliver projects.
OnStation is the digital stationing standard adopted by state DOTs, county engineers, and city public works departments. The numbers are the proof that contractors and CEI partners follow.

The contractors follow.
One state DOT customer purchased 320 inspector licenses. They didn't issue a rule. They didn't write digital stationing into a spec book. They just made OnStation the way their inspectors documented work — flags, photos, notes, forms, all tied to a station.
The contractors working agency projects watched it happen for one season. By the end, sixteen of them had bought their own licenses — off their own budget — to match the standard.
flags
With OnStation, most disputes never happen.
The ones that do, end at the data.
When agency, contractor, and CEI teams document together — same station, same photo, same timestamp — most disagreements get caught early and resolved before they ever become claims. Collaboration is the prevention.
And when one does come: a contractor filed an $80,000 claim against the agency for additional pavement depth they said they'd installed. Without proof, that's an awkward conversation. With station-tied depth-check flag photos taken during the work, it isn't a conversation at all.
"That's about eighty thousand dollars they were looking for — and that was it. No more conversation to be had."

Drop the flag once. The project sees it.
A flag captured by one person becomes a record that can be shared on multiple levels. Inspectors, agency staff, contractors, and CEI partners all open the same flag, view the same photos, and read the same notes. The conversation happens on the flag itself — not in someone's inbox.
From the field
This is exactly why I wanted this app. All this is now on record and we can all come back to it.

Every year, workers are killed in road construction zones.
Active Worksite™ tells drivers someone is working ahead.
No CFO asks for the ROI of not having a worker hit by a car. Active Worksite™ broadcasts your crews' live location to drivers — anonymized, only when workers are within 130 feet of the centerline, in apps drivers already use.
The digital stationing partner for AASHTOWare Project.
Every agency licensed for AASHTOWare Project can integrate the Construction & Materials module with OnStation via AASHTOWare OpenAPI. Field-captured data — flags, photos, station-anchored notes — flows into your system of record without redundant entry.
"Agency teams need reliable ways to translate what's happening on the ground into their system of record. This integration with AASHTOWare Project extends the power of open integration, giving members unprecedented access to jobsite data where and when they need it."

The Reality of Civil Design File Standardization
Project CAD files don't arrive clean.
We take in design files from agencies across the country, in every format and fidelity. We know what shows up, because we build the projects.
Alignment formats received across a recent submission of 138 projects.
What comes in
What comes out
One digital alignment. Live stationing on any phone or tablet, in the field.
In a sample of project submissions from a single state, alignments arrived in eight different formats. Representative of what we see; the mix shifts by agency and project.
We Work With You
OnStation meets each DOT at their stage of design file distribution.
Your CAD team keeps its tools
OpenRoads Designer, MicroStation, Civil 3D. Same software, same workflow.
Your survey keeps its coordinate system
We work in your project's zone, datum, and units, and reproject correctly when a project calls for it.
Your deliverables stay in your format
Submit intelligent DGN, LandXML, ALG, and more, exactly as you produce them today.
Your field crews just open a map
Live stationing on any phone or tablet. No CAD seat, no training, no new file to make.
If your design or survey software exports it, we can usually bring it in.
Coordinate Fidelity by Default
Your coordinate systems and datum remain.
State Plane and county zones
Single and multi zone state plane, plus county coordinate systems.
US Survey Foot and Int'l Foot
We honor the foot definition your project was built in.
NAD27 through NAD83(2011)
Horizontal datums matched to the source.
Ground to grid scale factors
Combined and project scale factors applied correctly.
Station equations and breaks
Alignment equations carried through to field stationing.
Reprojection between systems
Move cleanly between zones when a project needs it.
Alignments, stationing, coordinate systems, and discipline layers are handled on our side, not yours.
