Augin is the augmented reality platform for construction. View, check and present BIM projects at 1:1 scale, right on the job site or at the office — exactly as they will be built. HOW IT WORKS Upload your model through Augin Web (web.augin.app) or the plugins for Revit, ArchiCAD, Tekla and SketchUp (via IFC). In Augin Web you federate the disciplines and create a Reference Tracker with a crop of the area you need; in the app, just open it, point the camera and see the project on top of the real world, at real scale. FEATURES • Reference Tracker: print the reference sheet and place it on site — the model appears aligned to the environment, at the exact spot and height where it will be built. • Partial view: projects too big for a phone now open — the app loads only the crop that matters, light and fast, with no external tools needed to cut the model. • Federated models: architecture, structure and MEP brought together in a single project, so you can check disciplines side by side right on site. • BIM information: tap an element to see its properties instantly; resolve questions with filters, section cuts and measurements without going back to the office. • Collaboration: walk through the project with avatars and present to clients and your team. • AR and 3D mode: visit the job site in augmented reality or explore the model anywhere. WHO IT'S FOR Architects, engineers, contractors and developers who want to take BIM off the screen: design review, site tracking, client presentations and sales.

sfirion BIM
This application allows users to import, view, and annotate Building Information Models (BIM) in IFC format. It supports adding photos, documents, and performing 4D simulations based on schedule information. Users can also create and share daily reports.
- Import and view IFC models (IFC-2x3, IFC-4)
- Add photos and documents to model components
- Place and reply to comments within the model
- Perform 4D simulations with schedule data
- Create and share daily reports
- Show/hide components and use cutting planes

BIM Viewer for IFC files with photos, documents and 4D simulation. SFIRION BIM With the sfirion BIM app, you can import, view, share, comment on, and enrich IFC models with photos and documents. If the IFC file also contains schedule information and the corresponding links to the components, the 4D simulation can be played in the viewer. FEATURES - Compatible with IFC-2x3 and IFC-4 - Show/hide components - Examine element properties - Intuitive handling with gestures - Cutting face for cutting open the model - Placing comments with reply function in the model - Placing photos and documents in the model - Documents, photo list / GPS grid - Sharing projects with other users - 4D simulation (prerequisite: IFC model contains appointment links) - Daily Reports BIM MODEL VIEWER View the 3D model and inspect the building elements for their properties. Hide elements or insert a cutting plane to look inside the model. Use the hierarchical model structure to hide and show entire groups of elements. COMMENTS Pin comments to specific positions in the model and color them (red, yellow, green) or reply to comments already set by other users with access to the project. Involved persons are notified about your entry by e-mail. PHOTOS Attach photos to specific positions in the model or add them via the photo list. If no location has taken place via the model, but GPS coordinates are available, these are stored and GPS photos can be viewed in relation to each other on a corresponding grid. If you take a photo directly via the app, an attempt is made to address the GPS transmitter of your device. DOCUMENTS Pin documents in PDF format to specific positions in the model or add them via the document list. These documents can then be accessed by you or by users with the appropriate authorization. This can be done via the list or via the corresponding markers in the model. 4D VISUALIZATION If the IFC file provided contains schedule information including links to the construction elements, you can view this information as a 4D visualization. DAILY REPORTS Create daily reports for the planning or construction process. Depending on your role, you have the option to create or read and countersign reports. Reports are automatically distributed via the app and email as PDFs. OTHER Supported languages: English, German
