BIMserver.org provides an open-source platform to enable collaboration in the architecture, engineering, and construction industry. It features a flexible core that supports various protocols and can be extended through plugins. The platform aims to help all actors in the industry collaborate more efficiently through an innovative, reliable, and responsible solution. Current work involves improving merging and federation capabilities while additional data and "satellite" servers extend the platform's functionality. BIMserver.org welcomes contributions to help address challenges and further enhance the open-source software.
