3D Repo (http://3drepo.org/), a spinout from University College London, is a multi-award winning company offering a Software-as-a-Service (SaaS) platform for Building Information Modelling (BIM) in the cloud. Instead of architects, consultants and contractors sharing massive proprietary files in a costly and time consuming manner, they can simply point their web browser to an encrypted knowledge base in order to examine each project stage virtually, even on mobile devices. With 3D Repo, users can then manage model revisions and highlight potential issues using live collaboration tools, which allow the whole project team to work from a single source of truth. More than 40 different 3D file formats are decomposed and federated in the company’s big data repository. Additionally, the project knowledge base can be accessed via VR giving a live experience which has applications in Health and Safety training and client experiences. The 3D Repo team has collaborated on a number of large scale projects with companies such as ARUP, Balfour Beatty, Skanska, Crossrail and Canary Wharf.
