BIM-based design competitions represent the first step in a BIM project. Having the result of a design competition available as a BIM model makes the entire procedure far more transparent and enables automated checks of all prerequisites (e.g. conformity with the space allocation plan, consistent path relationships, and compliance with building codes). It also adds efficiency to the process of ascertaining quantities, volumes, and other key data. Thanks to our expertise in the area of design-competition procedures and BIM applications, we are able to help our clients when it comes to formulating the specifications that are to be met to secure efficient competitions for specific projects and project phases. BIM-based calls to tender allow participating teams to continue to directly apply the specifications (e.g. space allocation plan).
