View IFC Models on Site Without a BIM License

View IFC Models on Site Without a BIM License: the model, finally where the work happens

On most projects, the 3D model stays trapped on a desktop in the studio or the BIM department. Meanwhile, the quantity surveyor, the site manager and the installers run their day from a phone: loose photos, WhatsApp messages and notes nobody ever finds again. The result is an expensive disconnect: the information that describes the project best almost never reaches the place where the work actually happens, so decisions get made blind.

This page is about opening and checking the IFC model on site, from your phone and without a BIM license, so the model is useful exactly where the work gets done.

What an IFC file is and why it’s so heavy

IFC (Industry Foundation Classes) is the open, neutral format for moving BIM models between programs. It’s the standard way to pass a digital building from one discipline to another without being locked into a single piece of software. The practical catch is size: a real-world IFC can run to hundreds of megabytes, and opening it has traditionally demanded a powerful desktop application. On site, with a phone and a patchy connection, that’s been a non-starter. The model existed — it just never reached the place where the work gets done.

Why the BIM license is a barrier in the field

BIM authoring tools are built to design, not to consult on a scaffold. They cost money per seat, carry a steep learning curve and need dedicated training. Asking a CCTV installer or a foreman to launch a modeling suite just to check one detail makes no sense. The outcome is predictable: the model is finished and paid for, but the people walking the site don’t use it, because they can’t open it or don’t know how. All that investment stops halfway, exactly where it should start paying off.

Open the IFC model on mobile, install nothing heavy

PinMy opens and navigates IFC models straight from a phone or tablet. No BIM license, no Revit, no high-end device. The model loads and you rotate it, zoom in and move around it with your fingers, like any app you already use every day: a pocket IFC viewer instead of a desktop full of plugins. For the field team, that turns the model into something you can check in seconds, exactly when and where decisions get made. What used to mean a walk back to the site office or a call to the studio now fits in your pocket.

Place pins directly on the 3D model

Seeing the model is good; being able to mark it up changes everything. In PinMy you drop a pin on the exact point of the 3D model where something needs attention — a clash, a detail built wrong, an assembly question. The pin stays fixed to that point in the model, so anyone who opens it later sees precisely what you meant. No more vague descriptions like “third-floor corner, near the downpipe.” The point speaks for itself. For a surveyor walking the job doing checks, that means logging the issue on the spot, in the moment, instead of reconstructing it from memory back at the desk.

Voice, photo, video and text: document without writing reports

Every pin holds whatever evidence serves you best in that moment:

• Voice. Record thirty seconds explaining the problem and get back to work; on site, talking is faster than typing.
• Photo and video. The real state of the point, with no doubt about what you mean.
• Text. A short note when that’s all it takes.

That evidence stays attached to the point on the model, with its date and author, and becomes a record anyone on the team can review later. It’s real documentation, with traceability — without the friction of sitting down to write a report every time something comes up.

2D and 3D in the same tool

Not everything lives in the model. Plenty of detail still sits in PDFs, drawings and site photos. PinMy brings both together in one project: you can pin on a PDF or a site photo and, without switching apps, on the IFC model in 3D. The team doesn’t bounce between five apps or scatter the conversation across channels — it works in one place where the drawing, the photo and the model coexist. That cuts the clutter and, above all, means information turns up when it’s needed.

Collaboration and guest mode: let the whole site take part

Coordination breaks down when half the team has no access. That’s why collaboration in PinMy is open: invite collaborators, and with guest mode let someone take part without long onboarding or barriers. The subcontractor replies to your pin, the technician adds a photo, the surveyor closes the item. The conversation happens on the model and the drawings, in plain sight, instead of getting buried in private chats nobody can search afterward. Every reply stays in context — and when it’s time to account for who said what and when, the information is where it should be.

What PinMy does NOT do (and why we say it plainly)

Let’s be honest about scope, because with a BIM-literate audience clarity beats any inflated promise. PinMy is the field layer: view, mark up and document on the model from your phone. It does not replace your authoring tools or your common data environment. Model design, quantities and structured exchange workflows stay where they are, in your desktop software. PinMy doesn’t replace Revit or your data environment — it complements them, putting the model in the hands of whoever is on site and feeding field context back to the rest of the team.
