3D modeling

Long before the term BIM (Building Information Modeling) became modern, we have been planning three-dimensionally. For us 3D models are not only planning tools or aids for structural calculations, but we integrate planning and structural design into an integral process.

Whether free-form structures of steel and glass, timber and glass or multi-storey buildings made of reinforced concrete, we always strive to help our customers through the comprehensive modelling of the structure to implement their projects at best.

Well-informed geometry

Geometry for us is never just a conglomeration of points, lines and surfaces in a Cartesian coordinate system, but always an informed basis with all relevant factors for an intelligent, efficient and appropriate implementation into the built environment. In this sense, we are not pure geometry experts, but experts for the development of complex structures, which can meet different requirements. This allows us not only to optimize the geometry of a free-form surface in terms of the planarity of the load- bearing and / or the façade elements, but also to integrate the structural and the façade design.

Thereby we can adjust our work optimally to the particular task and the specific design idea and develop customized holistic systems together with our planning partners. We are conceptual planners of complex geometries from the initial concept to completion, but at the same time we can contribute our decades of experience in the design and construction of complex structures and thus fertilize the design process.

parametric structural modeling

In architecture parametric modeling is an increasingly important planning and design tool. Parametric models describe geometries and architecture not statically but dynamically, i.e. a model is defined by variable parameters, making it easy to modify the model.

With parametric structures we are able to react quickly to changes and to calculate and analyze many different variations in real time. It is important for us to communicate with architects in the same common design language and to be able to work closely together. Therefore we do not only use the tools but continue developing them ourselves.

Structural optimization

Parametric structural models allow the creation of many different alternative solutions for a task in a split second. In conjunction with modern optimization methods and filter algorithms efficient and intelligent variants can be found that would not be possible in a traditional manual design process. Thereby the efficiency may not only be found in terms of structural characteristics but also in other functional and architectural disciplines. In a multi-objective optimization process for example, aspects of climate and façade design can simultaneously be considered (alongside) with the structure.

We can develop specifically adapted structures which require a minimum amount of material. Thus in collaboration with the architects efficient, intelligent structures evolve. Their creation process and the structures themselves do not only meet the current state of the art, but also support the architectural idea and develop it further.


Similar to coordinated 3D planning, Building Information Modeling is suitable for the geometric alignment of different planning disciplines by means of model analyses and collision control. In addition to the purely geometric information, additional information, so-called attributes, is attached to the individual elements and objects. In addition to collision control, the focus lies here primarily on improved communication in the project and on a coordinated model as the basis for tendering, construction and operation.

The long-time processing of complex building tasks using computer-assisted, parametric tools has long been anchored in the office structure of Bollinger + Grohmann in various project teams and locations.In order to meet the requirements of the market for a BIM process ordered by the client, Bollinger + Grohmann has adapted its office structure accordingly with the start of the BIM implementation as central planning process. The focus of the team goes beyond the processing of complex geometries and operates across all the locations.

One of the core competencies of the new group is process moderation. At the beginning of a project, this superordinate team defines the internal and external project requirements into an appropriate workflow in cooperation with the planning team. In addition, it is now standard to implement a data manager below the project management level. This data manager deals exclusively with the control and administration of the internal and external data records. The central function of this workflow described above is to initiate an integral, transparent, adaptable and evaluable internal planning process for each project.

We can deal with both open and closed BIM processes and provide the ideal software for almost every requirement and scope of work. Several applications can be provided for model checking.
