3D Repo launches web solution for 3D construction models

BIM technology innovator 3D Repo has announced the release of the first web-based, real-time change detection software for 3D construction models

The cloud-based solution provides a fast and reliable way to detect all changes in underlying 3D construction models, in real time, via an encrypted web browser. The patent-pending innovation is a first for the industry as it operates on any 3D models, regardless of their file type, software used to produce them or file size. Called 3D Diff, the 3D Repo solution also allows users to share visualisations with project partners and stakeholders irrespective of location or time-zone.

Dr Jozef Dobos, CEO of 3D Repo, said: “The uniqueness of our change detection algorithm means that users can mix and match models from different modelling tools and pipelines and still be able to spot exactly what has changed over time between any two revisions.

“This becomes invaluable, not only during the design coordination stages, but also throughout construction when contractors introduce as-built models. It is also important for litigation when the proof of who did what and when may result in legal liability and financial claim.”

By comparing the actual geometry of construction models rather than underlying, software specific object IDs or labels, 3D Diff can detect changes between models from different sources. For instance, a user may pass 3D models from PDMS to Navisworks as well as to Tekla due to project specific requirements. Without 3D Diff, there is no way of verifying what data has been lost in translation from one package to the next. 3D Diff also runs in real time, regardless of the model file size, so even the largest and most complex projects can be instantly differenced.

3D Diff requires no installation of desktop software, data is fully encrypted and project privileges, such as view only or edit, can be assigned to individual project partners.

The 3D Diff digital solution builds on 3D Repo’s award-winning cloud-based BIM platform that allows users to access, via the web, the latest 3D construction models and make real-time changes and informed decisions. Often described as an online knowledge base, the 3D Repo platform is different from other collaboration tools as it uses a component-based database – meaning that information is live, useful and accessible throughout the entire project lifecycle.
