Directly on Your Jobsite.
No complicated setup. Stick a printed Alignment Target on the pre-determined location on site, point your camera, and watch your 3D models lock into place in real life. Compare digital plans with real construction instantly.
How It Works in 3 Simple Steps
Anyone on site can use OnsiteBIM in seconds. No training or surveyor tools required.
Place Target in BIM & Print
Place the Alignment Target inside your 3D BIM model, export your IFC file directly to OnsiteBIM, and stick the printed Alignment Target on the pre-determined location on site.
Point Your Camera
Open OnsiteBIM on your iPhone or iPad and point your camera at the Alignment Target. The app recognizes it instantly.
Inspect in 3D
Your 3D model locks right into place. Walk around, look behind walls, check pipe locations, and measure distances.
Built for Real Jobsites & Real People
Powerful features made simple enough for anyone to inspect construction quality in minutes.
6-DOF Target Anchor Auto-Alignment
Place Alignment Targets directly inside your 3D BIM model origin points, extract your IFC file, and stick the printed Alignment Target on the jobsite. Simply point your camera—OnsiteBIM locks and snaps your 3D mechanical equipment, MEP assemblies, or architectural 3D models directly onto physical target coordinates with sub-centimeter precision.
- Sub-Centimeter 6-DOF Accuracy: Calculates exact position, elevation, and orientation (X, Y, Z) instantly.
- Persistent Scene Anchor: Models stay rigidly locked in place as you walk around the jobsite.
- One-Tap Re-Align: Instantly re-calibrate or switch between multiple on-site targets with the tap of a button.
- 100% Offline Autonomy: Zero internet connection or cloud processing required on the field.
Instant 3D Clearance & Surface Tape Measure
Measure physical corridor widths, slab elevations, and equipment clearances in 3D AR space with millimeter surface accuracy. Real-time laser targeting lets you verify field conditions against design tolerances in seconds.
- Instant Dual Readouts: Live simultaneous readouts in both metric meters (2.40 m) and imperial feet & inches (7' 10").
- Dedicated Measurement HUD: Built-in Undo, Clear, and Done controls with high-contrast tactile buttons.
- Surface Snap Targeting: Locks precisely onto physical concrete slabs, walls, and digital model geometries.
- Jobsite-Ready Touch UI: Large touch targets designed for quick operation with work gloves.
Dynamic 3D Model Transparency & Inspection
Inspect concealed MEP utilities, ductwork, and conduit with dynamic real-time model transparency. Use the responsive dark-glass HUD slider to smoothly blend digital 3D models over active jobsite environments from 0% to 100%.
- Smooth Real-Time Slider: Seamlessly fade 3D BIM models over live camera feed to verify pipe & duct alignments.
- One-Tap Quick Presets: Instantly snap to 25%, 50%, 75%, or 100% transparency with work gloves.
- Scene Locked Telemetry: Keep inspection views firmly anchored while adjusting visibility.
- Detect Clashes Early: Catch MEP and structural discrepancies before drywalling and concrete pours.
Direct On-Device Multi-Format 3D Model Engine
Import your project files directly to your device with zero cloud conversion or third-party server processing. OnsiteBIM features an on-device rendering engine engineered specifically for open standards and modern 3D file formats.
- Native OpenBIM IFC: Direct parsing and display of industry-standard .IFC models without file conversion.
- Wide Format Support: Import .IFC, .GLB, .OBJ, .STL, and .USDZ files directly from Files, AirDrop, or local storage.
- Jobsite Samples Catalog: Explore pre-bundled architectural structures, structural steel frames, and MEP skids.
- Zero Data Transmission: Proprietary models stay 100% confidential and stored locally on your device.
Millimeter Precision Placement & Polar Joystick Nudge
Need to fine-tune placement or position models without physical targets? OnsiteBIM equips you with an on-screen tactical nudge pad and circular polar joystick for sub-centimeter model adjustments directly on site.
- Polar Coordinate Joystick: Smoothly nudge models along physical X and Y building grid axes.
- 10mm Precision Stepping: Toggle calibrated step increments for exact millimeter adjustments.
- Multi-Axis Navigation Tabs: Dedicated tactile modes for Move, Rotate, Elevate, and Scale.
- Elevation Leveling Lock: Lock height while nudging horizontally to ensure models stay pinned to true slab grade.

Jobsite & BIM Workflows Answered
Everything contractors, BIM managers, and project engineers need to know about using OnsiteBIM on active jobsites.
No. OnsiteBIM is 100% offline autonomous. It runs entirely on-device without requiring an internet connection or mobile data. All 3D model rendering, camera tracking, and Alignment Target recognition happen locally on your iPhone or iPad, making it fully operational in deep basements, tunnels, remote construction sites, or zero-connectivity concrete cores.
OnsiteBIM natively supports the OpenBIM .IFC standard (IFC 2x3 and IFC4) with zero cloud conversion. You can export directly from Autodesk Revit, Graphisoft ArchiCAD, Tekla Structures, Vectorworks, Blender, or Rhino. In addition to IFC, OnsiteBIM supports .GLB / .GLTF, .USDZ, .OBJ, and .STL formats.
When you point your camera at a printed Alignment Target, OnsiteBIM calculates the camera's exact 6-degree-of-freedom (6-DOF) spatial pose (translation X, Y, Z and rotation pitch, yaw, roll) relative to the target's physical geometry in milliseconds. The model's origin snaps and locks onto that exact jobsite coordinate, maintaining rigid anchor persistence as you walk the floor.
Never. Your intellectual property never leaves your device. OnsiteBIM does not transmit, upload, or process your 3D models on any external cloud server or remote database. Files imported via Apple AirDrop, Files app, or local storage stay encrypted within your device's local sandbox, complying with strict NDA and enterprise AEC security standards.
The standard 150 mm (15 cm) target printed 1:1 on A4 or US Letter paper is optimal for typical indoor rooms, MEP inspection corridors, and structural columns (detectable from 1 to 7 meters away). For expansive industrial bays, civil works, or high ceilings, our built-in Alignment Target Generator allows you to export high-resolution targets scaled for larger boards.
All core capabilities—including 6-DOF Alignment Target auto-alignment, 3D model opacity adjustment, 3D clearance tape measuring, and polar joystick fine-tuning—work seamlessly across all iPhones and iPads running iOS 16+. Devices equipped with Apple LiDAR (iPhone Pro and iPad Pro models) unlock additional real-time physical depth occlusion, masking virtual MEP ductwork behind real concrete columns and partitions.
