HCSS Docs & Plans or OnStation: Two Different Tools, Two Different Outputs

Heavy civil contractors are asking the question more often: Do we really need OnStation if we already have HCSS Docs & Plans? Or, earlier in the buying process: which tool is right for our crews?

It is a fair question. Both products show your location on a map. Both let you take photos in the field. The overlap looks real.

It disappears the moment you look closer. Docs & Plans is a plan management system. OnStation is a field stationing platform. They were built for different jobs, and they produce different outputs. Companies that understand the difference get value from both. Companies that confuse the two end up paying for one tool and wishing it were the other.

Designed for different problems

HCSS built Docs & Plans (formerly HCSS Plans) to solve the problem of a single source of truth for plans, revisions, and markup. Project managers were drowning in paper plan sets. Field crews were building off outdated revisions. Office teams could not get markups back from the jobsite. Docs & Plans answered that brilliantly. Upload your plans, manage your revisions, share annotations, run takeoffs, and export as-builts. The plan room moved from a trailer to a tablet, and that was a big win for the industry.

OnStation was built to solve a different problem. Crews on linear projects could not reliably answer the most basic question on a road job: “Where am I?” Stationing is the language of road construction. Pay items, inspections, and disputes are all recorded in stations. But on a five-mile resurfacing project, stationing on the ground was a guess at best, a hike to a marker at worst, and a survey crew at the most expensive.

OnStation made stationing live. Just as Google Maps shows you where you are while you walk, OnStation shows your station and offset while you work. When something matters in the field, your crews capture it on the spot. A photo of the work. A note about a condition. A test result, a delivery, or a field change. OnStation tags it with the station, offset, date, time, and user. Your team is not stopping work to document. They are not walking back to a marker. They are not trying to remember at 6 p.m. what happened at 10 a.m. The record is built while the work is being done, by the people doing the work.

That is the foundational split. Docs & Plans manages the design. OnStation captures the field.

Reference stationing vs. live stationing

Both products will give you a station readout. One does it in the field. The other needs the field to come to it.

Docs & Plans uses what is best described as reference stationing. A foreman taps a marker on the plan sheet, and Docs & Plans returns the station, offset, and survey coordinates for that point. Useful information. The catch is that this only works after a real setup process. Someone in the office must load the plan sheets, calibrate them against known control points, align them to real-world coordinates, and configure location services. Done correctly, the blue dot lands where it should. Done incompletely, the foreman is back to looking at a static drawing.

OnStation uses live stationing. Open the app, find your project, and your station and offset are right there at the bottom of the screen, updating as you move. There is nothing to calibrate or align. The crew gets the value on day one, not after hours of someone’s time spent configuring each page.

That distinction is not technical. Imagine a foreman who can rely on the data he needs every day to be there when he needs it. He’s not waiting on office teams to finish calibration or configuration of his plan pages. Field tools earn their place in the truck by being usable in the truck.

Geotagged photos vs station-stamped photos

Both products let you take photos. The metadata each one attaches tells the rest of the story.

Photos taken in Docs & Plans are geotagged. They carry latitude and longitude. They land in a folder organized by project, by date, and by foreman. That is good photo management. It is not field documentation.

Photos taken in OnStation are station-stamped. Every image carries the station and offset that matter to the project, the date and time it was taken, and the user who took it. When the contractor sends a billing team a photo to verify a pay item at Station 142+50, that photo does not need to be matched to a plan sheet later. The match is already done. The metadata speaks the language of the contract.

Latitude and longitude are coordinates. Station and offset are pay items. The contractor who can produce a station-stamped photo of the work, on demand, has a defensible record. The contractor producing a folder of geotagged images is starting an organizational project with the meter running.

Mathy Construction lived this. Their density technicians were running compaction tests behind the paver, then driving back to the office to record results. It required sixteen-hour days because a test with no station attached had to be reconstructed later. With OnStation, every test is logged with the station already attached, where it was taken, in the format that goes into the closeout record. They saved more than two hours per technician per day. Across seventy-five QC employees and a one-hundred-eighty-day paving season, that is roughly $18,000 per technician per year. The math compounds because field documentation is no longer a second job. It is part of the field work itself.

The shelf problem nobody wants to talk about

Here is the harder part of the conversation. Some companies buy Docs & Plans expecting to capture field data, only to find the field never adopts it as hoped. The licenses sit on the shelf. The crews fall back to phones, paper, and memory. The office team blames the crews, and the crews blame the tool. Both are partly right and mostly missing the point.

Docs & Plans was built for the office. It extends into the field and does plan viewing, revision control, and markup sharing well. But it was not designed to be the primary tool a foreman uses while standing in the dirt. The setup burden, the calibration sequence, and the dependency on someone else doing prep work in the office before the field can use it are not bugs. They are how a plan management system works. They are also why field adoption stalls.

When OnStation enters the conversation, it sounds like another version of the same promise. Why would this one be different? Because OnStation was built the other way around. The field is the starting point. Foremen use it on day one because it does not require them to set up anything. The office benefits second, when station-stamped photos and notes start flowing back in a format the billing team and the project manager can use. Docs & Plans starts in the office and reaches toward the field. OnStation starts in the field and reaches toward the office. Same project. Different direction.

The companies that find this out the hard way are not the ones that picked the wrong tool. They are the ones who bought a plan management system and asked it to be a field tool. Two different jobs. Two different tools. Two different outputs.

How to decide what you actually need

Start with the output. Ask the question your project manager will ask at closeout: “When this project is over, what record do I want to have?”

If the answer is organized plan sets, controlled revisions, takeoffs, and exported as-builts, Docs & Plans is the right tool for that work.

What most contractors lack is a station-anchored record of what actually happened on the ground. Photos tied to the alignment. Test results tied to the station. Notes from the foreman are tied to the cost code. Forms completed at the moment the work was done.

If the record you want to have at closeout gets your billing approved, your change orders paid, your disputes settled, and your closeout package out the door, then you’re in the market for a different tool. Plan management does not produce that record. Field stationing does. 

The strongest heavy civil teams use both. Docs & Plans handles the design side. OnStation handles the field side. Together, they cover the project from drawing to documentation.

Two different tools. Two different outputs. Pick the one that solves the problem you actually have, and you will not be the contractor wondering why the field never picked up the software you bought them.

See it in the field

Stop wondering whether your field crews will actually use the software you buy them. Schedule a demo and put OnStation on a live project this week. Setup takes 10 minutes. Your crew is on it the same day. The first photo your foreman captures will have a station attached. That is the moment you will know the difference.
