Station Finder
Gives every person on a road construction crew an instant location. No stakes. No survey wheel. No call to the PM.
- Live station and offset, GPS-driven
- Alignment locking, jumping, MM/LRS conversions
- Works on any phone — no hardware
- Offline mode for dead zones
Hoffman Construction: 3 utility strikes avoided on a single project — knowing exactly where you are stops the digger before the line.
Flag & Chat
Drop a flag at any station. Start a conversation tied to that location. Everyone on the project — your crew, the inspector, the prime, the DOT — sees the same thread.
- Flags pinned to station and timestamp automatically
- Photos and notes attach to the flag, not a group text
- Group chats by project, alignment, or crew
- Shared with subs, inspectors, and DOT staff
State DOT: 9,077 flags dropped across 200 projects — every one tied to a station, with the right people looped in.
Camera Notes
Every photo gets stamped with the station, alignment, date, and time — automatically. The kind of documentation that holds up in a pay-app dispute or a DOT audit.
- Auto-tagged to station, offset, and alignment
- Date- and time-stamped
- Searchable in the Data Portal
- Tag by category — rework, change order, safety
RS&H, I-4 corridor: a guardrail location dispute resolved in seconds — instead of hours of paper-pulling — using auto-stamped photos.
Forms
Custom field forms — density tests, inspection checklists, cross-slope measurements — filled out on the phone, locked to the station they were captured at. Data flows into the Data Portal and your existing tools.
- Custom fields for any test or daily report
- Location-locked to the station of capture
- HCSS HeavyJob integration syncs your data automatically
- Trimble, TransTech, FleetWatcher, GNSS integrations
Mathy Construction: $18,000 saved per density technician per season — 2 hours back on every shift, captured in-form on the phone instead of back at the office.
Active Worksite™
One in five construction fatalities happen in highway work zones. Active Worksite shares your crew's live location with the traveling public — drivers get alerted only when approaching active personnel, not a static work zone sign.
- Real-time alerts to drivers near active crew
- Works on any phone the crew already carries
- No extra hardware. No separate app.
Every year, 850 people are killed in U.S. highway work zones.1
Active Worksite™ tells the traveling public exactly where your crew is — live, anonymized, only when they’re within 130 feet of the centerline. Drivers see “Workers Ahead” in apps like Waze. Crews work knowing they’ve been seen.
“It’s given our crews a stronger sense of security knowing that drivers are being alerted when they’re entering an active work zone. The more drivers we can reach, the more effective these safety warnings will be.”

Real-time alerts
Drivers see exactly where work is happening — not just project limits.
Only when crews are actually working
Breaks the “empty work zone” habit drivers have learned to ignore.
Risk reduction for executives
Documented commitment to crew safety, includable in your TTC and safety plans.

Same app. Same phone. Different jobs — same problem solved. Find what your role gets out of it below.
Prime Contractor
Crews stop work to figure out where they are. Documentation disputes delay pay apps and change orders.

CEI / Inspector
Hours on location tasks and paperwork instead of expert inspection. Disputes you can’t prove without paper records.
36 minutes → 6 minutes per hazard documented — RS&H, I-4 Corridor

Sub-Contractor
Showing up on an unfamiliar project. No idea where the punch-list items live. Calling the PM to figure it out.

DOT Agency
No shared platform across contractors and inspectors. Paper logs. Closeout disputes that drag on for months.

Quick answers to the questions every crew has.
Most teams ask the same questions when they hear about OnStation for the first time. Here’s the short version.
Do we need new hardware?
No. OnStation runs on the iPhones and iPads your crew already carries. No survey gear, no rugged tablets, no rental fees.
What about dead zones?
Offline mode catches your project the moment you open it. Crews keep working from accurate stationing even when signal drops.
Is our project data secure?
SOC 2® Type II certified. Encrypted in transit and at rest. Your data is yours — exportable anytime, with audit-ready records.
How long until our team is up to speed?
Most users are productive on day one. Setup takes 5 minutes. Onboarding takes 10. Crews don’t need a manual to find their station.
Can DOT inspectors and primes use OnStation too?
Yes. Inspectors, primes, and DOT staff can all access the same project. Everyone sees the same stationing, the same flags, the same chat threads — no version mismatch.
What kind of plans does OnStation work with?
OnStation works with alignment files (LandXML or ALG), PDF plan sets, CAD project layers (DGN, DWG, DXF), and work items in Excel or text format. Send us what your engineer or DOT provided and we’ll build the project from there.
How does OnStation pricing work?
Pricing is per-project and scales with project size. Send us the plans and we’ll put together a quote — no procurement gauntlet, no annual commitment to get started.
From plans to working crews. We handle the rest.
No long onboarding. No professional services contract. Send us what you have, we’ll do the rest.
Send us your project files
Whatever your engineer or DOT provided — alignment files (LandXML or ALG), PDF plan sets, CAD project layers (DGN, DWG, DXF), and work items in Excel or text format.

Utility strikes avoided on a single project using OnStation’s design overlays. “It takes about a minute to pull up the utilities tab and see what is around me.”
Hoffman Construction
