The building structure is the backbone of every construction project. It is responsible for the stability and serviceability of a building and greatly influences the extent of its use. Structural engineering is the original and core competency of Bollinger + Grohmann Ingenieure. With an understanding of each design we create individual structural solutions based on our continuously developing strength and expertise in structural engineering. Bollinger + Grohmann Ingenieure always seek the optimum structural solution.
We avoid dogma, question the status quo and engage ourselves directly with the unique challenges of each individual project. The successful execution of an aesthetic, functional and cost-efficient solution is our goal. We seek to join the design planning process as early as possible and accompany our projects from the initial concept designs through to final completion.
Construction methods and material
We utilise a broad spectrum of possible construction material and building types. Whenever necessary we use our commercial independence as consulting engineers to develop new solutions together with our partners in industries and universities.
Our expertise ranges from ultra-lightweight construction with carbon fibres and textile membranes through to timber, steel, reinforced concrete, structural glass and prestressed structures.
One of our prominent areas of specialty are complex geometrical and delicate structures, where we are one of the pioneers in the development of modern planning tools as well as design implementation.
As engineers these tools are not an end in themselves but, they rather help us to solve unsolvable problems for the owners and design team and to ultimately make them feasible. This is true for instance with the execution of imperfect free forms, the use of robotic techniques or with geometrical optimisation.
All buildings require a solid foundation. In addition to traditional footings and mat slab foundations we provide solutions for specialised deep foundations, combined pile-slab foundations and waterproof concrete basement foundation including all required on-site engineering supervision.
Further foundation and excavation measures including watertight cofferdams, sequent piling and underpinning solutions (e.g. high pressure injection) round off our geotechnical portfolio.
Bollinger + Grohmann Ingenieure have expertise in the area of dynamic analysis which is required for complex problems which cannot be solved with standard structural modelling tools. Such problems include vibration analyses and the calculation of moving systems. We develop solutions for every challenge from the analysis of moving structures to the development of safe building structures in seismic zones.
Our experience ranges from fatigue analysis of bridges to base-isolation of high-rise buildings in high seismic zones.
Our services in the domain of Timber Structures comprise the structural design of all building types during all planning stages according to HOAI. We work on projects ranging from single-family house construction up to wide-spanning timber structures. This also includes the planning of temporary structures and modular construction.
Our services include: the development of optimized structures for all building types and special construction, elaboration of the structural analysis, development of special details and innovative solutions, support for the detailed execution design, 3D planning, parametric development of structures and BIM-planning.
During the planning process of timber structures, the integral development of the project is our priority. In addition to the services of structural engineering, we are therefore also responsible for the building physics and fire protection (elaboration of fire protection concepts). This combination of design services facilitates the planning process and leads to efficient, cost-effective and high-quality solutions that we develop in close cooperation with architects, clients and local authorities.
