Office
The firm was originally founded as a sole proprietorship in the 1970s by Friedrich-Josef Weichinger. In 1991, together with the founding partners Willi Förster, Rolf Sennewald, and Hansjörg Burggraf, he transformed it into a limited liability company (GmbH). From the very beginning, Hansjörg Burggraf managed the firm as a managing partner.
Responsibility
As structural engineers, we bear the responsibility for environmentally friendly and resource-efficient construction. In close collaboration with all disciplines, our structural design makes a significant contribution to realizing projects where economic, aesthetic, and functional aspects are integrated on an equal footing. With dedication, expertise, and enthusiasm, we embrace these challenges.
Sustainability
Through our structural engineering work, we contribute to shaping our built environment, with sustainability becoming an increasingly important focus. In particular, building within existing structures and densifying urban areas present complex challenges for structural design. Today’s challenge is to create structures that are slim, material-efficient, and yet flexible enough to allow for adaptive reuse after their initial lifecycle, without requiring structural reinforcement or modification.
To support the selection of appropriate, resource-efficient systems, we advise clients and design teams during competitions, feasibility studies, and early project phases (LPH 1–2) on ecologically sound solutions. Our bwp Sustainability Tool, based on the Ökobau.dat 2024-I database (in accordance with DIN EN 15804 +A2), is a key instrument in this process. It enables the comparison of different structural systems regarding their environmental impacts, CO₂ balance, and Global Warming Potential (GWP). Through a partnership with TU Munich, we ensure that the latest scientific insights are integrated into our sustainability strategies.
Expertise
New technologies, such as artificial intelligence and advanced digital planning methods, are increasingly influencing design processes. Through our long-standing engagement with these developments, we are able to ensure high process quality. We have extensive experience in interdisciplinary digital planning. Already in the early design phases, we integrate alternative structural solutions and systematically evaluate their respective advantages and disadvantages.
Scope
With four central business areas, we professionally cover the entire spectrum of modern structural engineering. Cross-disciplinary services such as construction supervision, quality assurance, fire protection, sound and thermal insulation, as well as assessments, feasibility studies, building documentation, and recurring inspections of existing structures complement our activities, all aimed at achieving holistic, high-quality planning and execution.
General Building Construction
Structural design for new buildings such as offices, educational facilities, residential, research, and healthcare buildings, using reinforced concrete, steel, or masonry.
Timber Construction
Structures made of solid wood, timber frame, and composite constructions (timber–concrete, timber–steel) for new buildings and extensions.
Refurbishment / Redevelopment
Renovations, conversions, additions, underpinning, partial demolitions, as well as structural inspections and assessments of existing buildings.
Infrastructure / Civil Structures
Bridges, excavation pits, retaining and foundation structures, as well as specialized deep foundation methods (bored pile walls, sheet pile walls, soldier pile walls, jet grouting, mixed-in-place, uplift anchors).
