All components of the solution were developed using open source technologies and universal free access. The contributions of this work will also serve to improve the set of tools and solutions available to the community. The developed platform will be available openly to all companies that want to engage in the BIM community and ought to actively participate in and foster the development, improvement, and promotion of this platform within the AEC sector.
