OnStation for Sub-Contractors | Defensible Documentation on Stationed Corridor Jobs
For Sub-Contractors

When the records
are thin,yours have to
be airtight.

One shared record across the prime, the sub, and the agency on every stationed corridor job — with your work in it from day one.

of annual revenue walks out the door as the Cost of Unproven Work. For most subs, that’s the whole margin.

The math nobody talks about

The work was right.
The record was thin.

Disputes that should have settled at zero. Pay apps revised twice. Change orders never written. It all flows from one place: nobody can prove where the work happened.

OnStation puts the station in every pocket on the project — sub, prime, and agency — and turns every flag, photo, form, and chat into one shared record that defends the dollar.

What it looks like on your corridor.

Defensive documentation. Punch-list closeout. Pay-app defense. Three use cases, one record.

Defensive Documentation

One record.
Built as the work happens.

On a 2-year corridor with a prime contractor and a DOT inspector, every flag, photo, and remediation note anchors to the station.

Mat checks, density tests, and joint photos — all anchored to the station, all visible to the prime and the agency in real time.

Lineal footage measured between flags. Material logs, thickness checks, and photo evidence build the record as the truck moves down the corridor.

NPDES inspections, BMP placements, remediation notes — station-anchored as you walk the corridor. The agency sees what you saw.

Fixture installs, base inspections, conduit pulls — every step photo-documented at the station, traceable through the project lifecycle.

Conduit runs, junction boxes, pull tests — documented at the station with photos. The record matches the as-built before the prime asks for it.

TCP element placements, sign installs, lane closures — geotagged and station-anchored. Proof of compliance, ready when the agency asks.

Walk. Text. Email. Hope.

Three apps, two inboxes, and a folder of paper. When the agency asks where the work happened, the answer takes hours to reconstruct.

One project. One record. Everyone on it.

Drop a flag at the station, add a photo, and it’s on the prime’s screen and the agency inspector’s screen in real time. The record isn’t yours alone — it’s the project’s. Built once. Trusted by everyone.

“Three apps, two inboxes, and a folder of paper became one record the agency could read on its own.”

“Which fixture was it again?”

Photo on a personal phone. Texted to the foreman. Forwarded to the PM. Nobody knows the station. Crew goes back to confirm.

One item. Everyone sees it. Closed together.

Drop the flag at the station. Add the photo. Tag the prime and the agency inspector. They see it in their app the same moment you do, with the same context. The inspector approves it from the field. The item closes — no email chain, no who-saw-what.

Punch List & Closeout

Date-stamped.
Station-stamped.
Dispute‑proof.

Punch-list items show up at the end of the job. The agency wants proof each one got addressed before sign-off.

Surface repairs, joint corrections, segregation fixes. Each item documented at the station with before/after photos. Agency signs off without a site visit.

Reflectivity callouts, line correction, symbol replacement. Each punch item closed with a station-anchored photo. The retainage flows on schedule.

BMP failures, silt fence repairs, slope corrections. Each fix logged at the station, visible to the prime and the agency the moment you submit it. NOI to terminate goes in with the shared evidence attached.

Relamps, fixture alignments, base repairs. The agency wants proof each one is fixed. Photo, station, timestamp — punch list closes without a back-and-forth.

Conduit repairs, junction box corrections, grounding fixes. Punch items close with documentation the inspector can verify without rolling a truck.

Sign corrections, channelizer replacements, marking fixes. Each punch item documented at the station. Agency signs off, retainage releases.

Pay App & Change‑Order Defense

Submit it once.
Get paid for what
you actually did.

Disputes over quantities, locations, or dates. Pay apps revised. Retention dragging. All because the record was thin.

Tonnage disputes. Mat thickness questions. Joint location debates. Station-anchored data shuts the conversation down before it starts.

Lineal footage disputes on frontage roads, transitions, and gore areas. Station-anchored measurements settle it. Pay app accepted the first time.

BMP quantity disputes. Disturbed-area calculations. Permit closure delays. The station-anchored record matches the as-built. Disputes evaporate.

Fixture count disputes. Conduit footage debates. Foundation depth questions. Each install station-anchored and photo-verified. Pay apps clear faster.

Conduit run disputes. Pull-test verification. Material quantity reconciliation. Station-anchored records make the pay app self-defending.

TCP element counts. Sign placement disputes. Lane-closure duration debates. Photo + station + timestamp settles it. Pay app submitted once.

Submit. Argue. Resubmit. Wait.

Crew-phone photos. No station anchor. Dig through text threads. 18 days of back-and-forth. Working capital stuck.

You, the prime, the agency. Same screen.

Station-anchored quantities. Photo evidence at every flag. When you submit the pay app, the prime and the agency are already looking at the record it’s built from. Disputes settle in minutes, not days.

Cost of Unproven Work

Four ways a thin record costs you.

The work happens in the field. The margin happens in the records.

01

Claim & dispute exposure

Negotiating against your own memory.

02

Rework & re-mobilization

Coming back to prove what you already did.

03

Cash flow drag

Pay apps stuck while documents get rebuilt.

04

Missed change orders

Scope creep done, never invoiced.

Why now

The prime is on it.
The DOT is on it.You’re the missing piece.

When the agency and the prime are working from one shared record and you’re not in it, the version cited later is theirs. Get on the project. Be in the record. Share the workspace.

Active Worksite™

Live traffic. Thin docs. Big risk.

If your crew works inside a traffic-exposed corridor, the safety record matters as much as the pay record. Active Worksite alerts approaching drivers and turns your safety program into an insurance-grade document.

Honest answers

Questions subs actually ask.

If the answer is “not a great fit,” we’ll tell you that on the call.

Licenses start at $468/person/year for Locate. Capture is $708. Data is $1,308. But the math that matters isn’t the license — it’s what you stop paying for. One avoided pay-app dispute typically covers the whole crew’s annual licenses. The prime’s flags belong to the prime; when your pay app needs evidence, your record has to be yours.
Probably not in the same way. OnStation pays back hardest on stationed corridor work with a prime and an agency on the project. Off-station sites (parking lots, subdivisions, solar farms), the flag-and-photo features still work but the station value doesn’t. Tell us your job mix on a call — we’ll be straight about whether the math works.
When the prime and the DOT run OnStation and you don’t, the corridor record gets built without you. That’s the version that gets cited later. Even if the prime isn’t on it, your station-anchored records still hold up. The record is yours, regardless.
Anyone who needs the station gets Locate ($468). Anyone who documents gets Capture ($708). Whoever runs the office side gets Data ($1,308). You don’t buy what you don’t use.
About 10 minutes. Corridor, stations, and design layers load from alignment data. Crew downloads, signs in, project is on their phone. If the prime is already on OnStation, your crew joins their project setup in minutes.
Seven state DOTs are direct OnStation customers. SOC 2 Type II certified. Every flag is a row in the audit trail — station-anchored, date-stamped, user-tagged. Agencies on the platform accept records natively. Agencies that aren’t still accept exports as evidence. The record holds up the same way a survey crew’s field book holds up — because it’s built the same way.
Yes. The access period runs on a real project before you sign anything. No card, no commitment. Start your access period above.

Your work is right.Make sure the record is too.

The sub with the cleanest record has the cleanest pay app.
