OnStation

OnStation App

About this app

OnStation gives road construction crews live digital stationing on any phone. Know your exact station and offset instantly — no stakes, no rover, no manual calculation. Document what you see, where you see it, with every photo and note automatically anchored to a station reference.
Used on more than 5,000 road construction projects by over 400 contractor agencies across the United States.
WHAT IT DOES
Open the app and see your exact station and offset, tied to your project alignment. Drop a flag, take a photo, leave a note — all automatically geo-referenced to a precise station and timestamp. Your documentation builds itself as work happens, not at the end of the shift.
WHO USES ONSTATION
★ Prime contractors and field crews — Eliminate location hunting. Tie every photo and note to a station. Build defensible records for pay applications and change orders. Density technicians log compaction test results directly in the field at the correct station, cutting hours of manual entry.
★ CEI inspection teams — Replace paper daily work reports with station-anchored photos, flags, and notes. Export in DOT-ready formats. When a dispute arises, the evidence is already there.
★ DOT agencies — Shared platform across contractors, inspectors, and agency staff. Real-time oversight, standardized documentation, and Active Worksite safety notifications.

WHAT CUSTOMERS SAY
"Saving two hours a day on a technician's time card is $100 a day — multiply that by our 180-day paving season and just one employee, you can save a considerable amount of money." — Derek Frederixon, QC Manager, Mathy Construction
"You use it once and you realize the value of it. Hands down, digital stationing is always going to point you in the right direction." — Chris Lundberg, Senior CEI Inspector, RS&H
"OnStation is definitely worth the price. I will probably be shot for saying this, but it should probably be charged more for what we get out of it." — Chris Potts, General Superintendent, Milestone Contractors

Ratings and reviews

After the 4.0 update/overhaul, there were issues with the app and I left a negative review. The on station team contacted me, because they were unaware of these issues. They spent the next week fixing these issues that happened, while also staying in contact. Overall this has been the best experience I've ever had with customer service. They constantly gave me updates and asked questions to ensure they were fixing all problems.

OnStation is an easy to use, high tech way to view your project and plans. It gives you the ability to see multiple layers(current and future utilities) in one place. If the GPS was a little more consistant it would get 5stars

I've had a very hard time getting photos to save with the overlay, and for the past 48 hours I've only had a blank white image where my project map should be.
