AR BIM CONSTRUCTION VERIFICATION

Custom AR BIM verification for your construction sites.

Plan versus reality: overlay the model on the real build and see where they diverge.

We build AR BIM tools that overlay your Revit and IFC models onto the real site, so your teams verify what was built against the design and catch clashes before they become rework. Not an app you rent. A custom platform we build around your workflow and hand over as yours.

Our product · DeltaARBIM

DeltaARBIM: our AR BIM verification platform.

DeltaARBIM is Shivlam's own product. We designed and built the AR BIM verification platform end to end, and it is live on three job sites: two commercial complexes and a hospital.The app overlays live 3D models (structure, walls, MEP pipes, HVAC layers) onto the real construction site through the device camera, so site teams verify what was built against the model and catch deviations on the spot. It reads IFC natively, works offline with no markers, and holds ±2 cm on site.Scans are registered into one coordinate frame so the overlay shares a single origin.Recognition may be AI-assisted. The alignment and the deviation are geometric, not estimated.The same team builds custom AR BIM tools for clients, on the same engine.

Detect clashes

Check every layer against the model before a brick is laid. AR clash detection removes costly on-site surprises.

Reduce rework

Cut on-site rework by catching deviations from the design before they escalate.

How the ±2 cm is measured. It is an on-site figure, not a lab one: the overlay is checked against the coordinated IFC model in place, on the three live projects DeltaARBIM runs on. It describes how closely the model sits on the built work while you are standing in front of it. For the rest of the chain, from takeoff to the site record, see construction tech.

3D Reconstruction

High-fidelity 3D models for as-built records, retrofitting, and digital twins. We turn LiDAR-captured point clouds into precise BIM deliverables that work with IFC, Revit (RVT), and Navisworks (NWD).

FAQ

What construction teams ask before an AR BIM pilot.

What is AR BIM verification and how does it work?

AR BIM verification overlays your approved 3D model onto the real construction site through a phone, tablet, or headset camera. Your team walks the space, sees the model at 1:1 scale, and checks that what was built matches what was designed, catching clashes and deviations on the spot.

How accurate is AR for as-built verification?

Accuracy depends on the device and site setup. On the platform we built for DeltaARBIM, the AR overlay holds alignment to within about 2 cm on live sites. We agree the accuracy target with you before a build so it fits your tolerances.

What hardware do we need?

LiDAR-equipped iPhone Pro and iPad Pro cover most field work, and headsets like Apple Vision Pro or Magic Leap suit hands-free use. We recommend the right mix for your workflow during scoping.

Which BIM tools does it work with?

We build around your existing stack, including IFC, Autodesk Revit, and Navisworks. If you use Autodesk Construction Cloud or another source, we connect to it during the build.

Do we own the tool, or is it a subscription?

You own it. We build a custom tool around your workflow and hand over the software, rather than charging a per-seat subscription.

How does AR reduce rework on site?

It catches deviations from the model before they are built on, so errors get fixed on screen instead of after installation. Less rework means fewer delays and lower cost.
