Centralise all project information between 12Build and Catenda

With the 12Build and Catenda integration, all BIM data is accessible in one place for every project partner. No more switching between platforms, no more version conflicts. Everyone works from the same source of truth.

Request more information About Catenda

One source of truth

Catenda acts as the central hub for all BIM data across your project partners. Connected to 12Build, that data flows automatically between both platforms. You always work with the most current information, without manual transfers or outdated files.

 

Why integrate?

BIM collaboration only works when everyone has access to the same information. With the 12Build/Catenda integration, project data stays consistent across teams, applications and companies. Less confusion, fewer errors and a smoother workflow from start to finish.
