Quick Answer
Remote field support lets office-based surveyors guide field crews in real time using GNSS receivers and cloud-based software like Emlid Flow 360. The office pushes updated drawings to field devices instantly, watches crew positions live on a map, and answers questions without driving to site. This cuts site visits dramatically and speeds up construction verification.
Why Remote Support Matters for Construction Teams
Somewhere right now, a surveyor is driving 45 minutes to answer a question that takes 5 minutes. The problem isn't the question, it's that the site crew had no way to handle it without someone physically showing up.
This costs real money when you multiply it across every crew, every site, every week. The solution is simple: give the office live visibility into what's happening on site, and give field crews tools that work without needing a surveying background.
How Field-Office Collaboration Works
The workflow splits cleanly between two roles:
Office Team: Setup and Support
Before anyone goes to the field, the office gathers control points, sets the coordinate system, geolocates CAD drawings, and prepares the project. With Emlid Flow 360, they upload everything to a shared workspace and invite field users.
The field team never touches the backend. They just open the project on their device and start working.
Field Crew: Capture and Verify
Superintendents and foremen open the project on Emlid Flow (iOS/Android) and walk the site. They're not surveying, they're doing quality checks: verifying that footings, sleeves, MEP elements, and utility structures are where the drawing says they should be.
The receiver handles positioning. The drawings provide reference. The user just needs to know what to look for.
Three Key Features That Make It Reliable
1. Shared Workspaces
Instead of everyone logging into the same account (which causes data conflicts), each person gets their own account within a shared project. Every file the office publishes appears instantly on every device. Measurements from the field show up in the office view immediately, attributed to the right person.
2. Instant Drawing Updates
When the design changes, the old way required re-exporting, re-emailing, and re-importing on every device. Some crews worked from outdated drawings for days. With cloud sync, the office updates the file and it's live for everyone immediately. No refresh needed.
3. Live Position Tracking
A superintendent can sit in the site trailer watching a foreman walk the site in real time on their screen. When someone starts measuring the wrong line, they can correct them before they've taken ten shots in the wrong direction.
This matters most when the person holding the receiver doesn't have all the context. They know how to capture the point. The office knows if the elevation is correct.
Practical Applications
- Utility verification: Check buried services before excavation without waiting for a surveyor
- Foundation checks: Verify footing positions against design within centimetres
- RFI documentation: Take screenshots showing position against drawings, upload to Procore or similar
- Multi-crew handoffs: Second crew sees exactly where the first crew left off
What You Need
This workflow requires RTK GNSS receivers like the Emlid Reach RS4 or RS4 Pro for centimetre-level accuracy, plus the free Emlid Flow app for field devices and Emlid Flow 360 for office management.
For construction teams already using RTK for drone mapping, the same receivers work for ground-based verification, giving you more value from the same hardware investment.

FAQ
Q: Do field crews need surveying experience?
A: No. The key is software that shows positioning directly on site plans rather than raw coordinates. If they can read a drawing, they can verify positions.
Q: What's the range for live position tracking?
A: As long as both field and office have internet connectivity, there's no range limit. The field device uploads position data to the cloud, and the office views it in real time.
Q: Can I use this with existing survey equipment?
A: Emlid Flow works with Emlid Reach receivers. If you have other GNSS hardware, check compatibility with your manufacturer's software for similar cloud collaboration features.
