A Usable Field Model
The future of transportation delivery runs on open, interoperable data that flows freely across the full project lifecycle and every organization involved. That vision has always been strongest in design and in the office, and hardest to realize where the work actually happens: in the field.
The alignment lives in the model. But the crew building the road, the inspector documenting it, and the agency overseeing it have rarely had a shared, open, location-accurate way to see it on the ground. OnStation was built to close exactly that gap.
OnStation is the digital stationing platform for road and bridge construction. It puts a live station and offset in every crew member's pocket and turns every flag, photo, form, and chat into a geo-located record that holds up when the work is questioned. With OnStation, location uncertainty is eliminated.
Taking the Design Model to the Field
OnStation imports the project's design data directly (DGN, DWG, IFC, ALG, LandXML, TBC, KML, and SHP) and renders the alignments, station, and offset live on any phone using GPS, accurate to within a few feet. The alignment leaves the model and reaches the person standing on the road.
Crew members don't need a rover, a survey crew, or a set of stakes to know where they are relative to the design. Design layers are viewable on the project map, with assets located at their designed station and alignment. Layers can be copied to capture metadata updates and field modifications, and date and time stamped photos confirm the work. The result: non-CAD users can use and edit CAD data in the field.
Every Record Tied to a Station
Everything a crew documents is tied to a station location. Every flag, photo, note, completed form, and measurement includes the station, alignment, offset, latitude and longitude, a timestamp, and the user who created it.
This is structured, location-verified, attributable field data, captured at the time of work rather than reconstructed weeks later. It's shared in real time across organizations, so the contractor, the inspector, and agency staff all work from the same record, tied to the same point on the ground.
Open data only delivers value when everyone contributes, which is why OnStation is built for the whole project team, not a single role. OnStation also supports mile markers, latitude and longitude, and linear referencing, with instant statewide conversions between those systems and the project stationing.
Built on Open Standards
OnStation aligns directly with openBIM. It reads open standards like IFC and LandXML and exports field data in open formats like KML and GeoJSON, along with PDF and CSV. Organizations fully own their data and can export it at any time.
OnStation is an AASHTO Data Alliance member. Agencies can connect through the AASHTOWare Project (AWP) OpenAPI and pass project pay line items directly to their field inspectors.
The Source of Ground Truth
A model is only as good as the ground truth it's fed. Digital as-builts, asset records for future projects, and a connected lifecycle all depend on trustworthy field data that is location-verified, timestamped, attributable, and exportable.
OnStation is that source of ground truth. It fills the gap between what happens on the corridor and what the systems of record can defend, without trying to replace the tools agencies and engineers already rely on. Design and modeling tools plan the work against the alignment. OnStation captures what actually happened at that alignment, geo-located and open, and sends it back where it belongs.
What OnStation Brings to Open Digital Delivery
OnStation brings a usable field model and accurate alignment in every crew member's hand, and a trustworthy, open record of what actually happened on the ground.
