BII GmbH (Building Information Innovator GmbH) is a software development company that offers innovative solutions for the construction industry.

Our software solutions are aimed at companies in the railway, building and civil engineering sectors as well as construction managers, construction planners and engineers.

BII GmbH pursues the vision of advancing digitization in the construction industry and significantly increasing efficiency, transparency and sustainability in construction projects through innovative software solutions.

With dProB, BII GmbH offers flexible and powerful software for planning, organizing and evaluating construction projects. Further modules and extensions are under development to meet the individual requirements of the construction industry.

dProB is a software solution for the efficient management of construction projects. It offers functions such as visualization and simulation of construction processes, evaluation of relevant performance parameters, and more.

dProB fits seamlessly into your BIM workflow. You can import classic BIM data into the software, carry out targeted analyses and validations and then return the results back to your digital workflow or BIM system. dProB serves as a supplementary tool for validating and optimizing planning and execution processes.

Geometries can be imported via IFC and FBX, track axes via DXF and LandXML, images in PNG and JPG formats, and schedules in CSV format. Exporting to CSV format is also supported.

Our beta subscription includes access to the software, technical support, and updates. Other options are available upon request.

A trial period is not provided as standard. If you are still interested in an individual solution, please contact our support team.

Yes, we offer student licenses for dProB. In order for students to gain access, a key administrator at the university must contact our support team to verify the university.

Please contact our support team.‍

A Windows PC with at least 16 GB RAM, a dedicated graphics card and a modern processor is recommended to use dProB.
