简介

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. WHAT IT DOES Open the app on any phone 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 without extra paperwork. 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 documentation in DOT-ready formats. When a dispute arises over where work occurred, the evidence is already there. DOT agencies — Create a shared platform across contractors, inspectors, and agency staff. Real-time oversight, standardized documentation, and Active Worksite safety notifications give agencies visibility that paper-based systems cannot provide. KEY FEATURES • Live digital stationing — instant station and offset on any phone, tied to the uploaded project alignment • Geo-referenced flags, photos, and notes — every observation auto-anchored to a station and timestamp • Design layer overlays — view plan sheets, utility maps, and CAD files on the live project map • Flags and chat — drop a flag at any location, attach photos and notes, share across the project team • DOT-ready reports — export documentation in standardized formats for closeout, audits, and compliance • Active Worksite — alerts the traveling public of construction worker locations via Waze and navigation apps • MM/LRS conversion — convert between stationing, milepost markers, and linear reference coordinates • Integrations — connects with HCSS HeavyJob, Trimble, TransTech, FleetWatcher, and GPS/GNSS receivers • Works offline — field documentation continues without connectivity RESULTS FROM THE FIELD • $18,000 saved per density technician per year — Mathy Construction • Guardrail dispute resolved in seconds vs. hours — RS&H, I-4 Corridor FL • GPS rover dependency eliminated from daily workflows — APEX Engineering • 3 utility strikes avoided on a single project — Hoffman Construction • "This is EXACTLY why I wanted this app. All this is now on record and we can all come back to it." — DOT Inspector, April 2026 ABOUT ONSTATION Founded in 2013, OnStation is the leading digital stationing platform for road construction.
