Bridge the gap between BIM and Digital Twins

3D Repo is a Software-as-a-Service (SaaS) platform for Building Information Modelling (BIM) coordination and digital twins. Through 3D Repo, multidisciplinary teams can communicate and access live BIM data through a web browser. It is a multi-award-winning, easy to use, encrypted digital platform for BIM data.

3D Repo is transforming how construction projects are designed and delivered by democratising data, mitigating risk and reducing complexity for architects, engineers and contractors.

It has already helped clients track progress and make informed decisions to deliver projects on time, manage health and safety and project risks, and achieve over 20% improvement in project coordination and efficiency.

Digital tools to help create a better built environment

The 3D Repo collaboration platform can help boost productivity, safety, and quality in line with the UK Government’s Industrial Strategy targets for construction by 2025.

  • 33% Lower costs – Reduction in the initial costs of construction and the whole life cost of built asset.
  • 50% faster delivery – Reduction in the overall time from inception to completion, for new build and refurbished assets.
  • 15% Improved productivity – Eliminate the gap between construction and the rest of the economy.

Cloud-Based BIM

Cloud-based BIM allows architects, engineers and contractors to easily access their 3D models from virtually anywhere. Storing BIM information in the cloud means stakeholders can upload and access the latest version of their models, and work from a single source of truth.

Issues can be identified and resolved in real-time or asynchronously among teams.

Communicating risks and hazards through email and offline spreadsheets slows down the design process. The cloud platform can manage this by logging all risk communication and notifying people when issues are assigned to them. Learn more.

Track and manage issues in 3D

Issue trackers maintain transparency and hold people accountable for their tasks. 3D Repo tracks all issues and actions in a central hub so everyone in the project team can see what actions have been taken to remedy them. Learn more.


Import your 4D projects from Bentley Synchro into 3D Repo. The integration enables site teams to identify, record, and resolve site hazards as part of a virtual construction sequence evaluation and training.

Drop pins at specific points in time during the construction sequence to go beyond design issue management and into construction issue management with the introduction of 4D issue tracking. Learn more.

Prevent injury and save lives with SafetiBase

Through its innovative health and safety management tool, SafetiBase, 3D Repo is helping to make the construction site safer by enabling teams to collaboratively identify risks and mitigate them before setting foot on a construction site.

SafetiBase was created as a consortium after receiving funding from i3P and Innovate UK. Partners include 3D Repo, Atkins, Mott MacDonald, Laing O’Rourke, Costain, Bentley, HS2 and others.

Using open-source technology, SafetiBase simplifies the process of sharing project health and safety information between the construction team, directly within their 3D models. It puts risk data into a digitised, uniform format to support consistency from start to finish.

SafetiBase works across any sort of construction or infrastructure project, from rail projects to airport terminals to house building sites.
