About 3D Repo
3D Repo is a browser-based BIM (Building Information Modelling) and digital twin platform that lets architects, engineers, and construction teams collaborate on 2D, 3D, and 4D models in a single cloud environment. It supports issue tracking, clash and change detection, health-and-safety risk management, and broad file-format compatibility so distributed project teams can identify and manage risks without installing software.
Pros & Cons
Pros
- Fully browser-based with nothing to install, so any stakeholder can collaborate instantly
- Strong change detection via patented 3D Diff that works across different file types
- Built-in health-and-safety risk management (SafetiBase) aligned to BIM standards
- Broad file-format support including Autodesk, Bentley, and open IFC/BCF formats
- Open API and embeddable viewer for custom dashboards and applications
Key Features
Cloud-Based Platform
Totally browser-based BIM environment accessible from anywhere with no software to install, keeping the whole project team on the latest model revisions.
Issue Tracker
Record pins directly in the 3D model to flag issues, assign them to specific stakeholders, and maintain a full audit trail for accountability and transparency.
SafetiBase
Collaborative health-and-safety risk register that associates risks directly to the model, conforming to PAS 1192-6 for structured H&S information sharing in BIM.
3D Diff Change Detection
Patent-pending tool that highlights exactly what changed between two model revisions across different file types and modelling applications, even when object IDs are missing.
Data Validation with Smart Groups
Group and validate model elements for progress tracking and reliable data outputs, democratising validation regardless of software expertise.
4D Construction Sequencing
Import projects from Bentley Synchro to evaluate virtual construction sequences, attribute risks to tasks, and support site induction and training.

Best For
BIM Coordination
Centralise multi-discipline 3D models in the cloud so architects, engineers, and contractors always work from the latest revision.
Clash and Change Detection
Use 3D Diff and issue pins to spot model changes and clashes between revisions before they reach site.
Health and Safety Management
Capture and assign project risks directly on the model with SafetiBase to mitigate hazards before construction begins.
4D Construction Planning
Sequence construction virtually to rehearse build order, train site teams, and identify hazards in advance.
