About us

A question of balance

We believe that the basis for successful planning work is a perfect balance between creative energy, discipline, and diligence.

We attribute our success in ambitious construction projects to material spanning knowledge and conceptual thinking. Our active participation with the themes and ideas of our planning partners plays a pivotal role in the development of a structural solution, which is integrated into the overall work.

Our commitment, creativity and enjoyment of our work have consistently produced many innovative ideas that are being used repeatedly in our construction projects. Our work, however, is ultimately measured by the quality of planning services rendered. Viable and proper planning documents, as well as the awareness of costs and deadlines, are viewed as a foundation for our successful planning.

The end result is a structure where our client’s objectives are realized in the most qualitative and cost effective manner.



In February 2009, the pharmaceutical company F. Hoffmann-La Roche AG made an international call for tender for the structural engineering work of their 178m tall office building. Our company was selected during the tendering process due to our references and methods of operation. Martin Stumpf took over the project management for Bau 1 in Basel and transferred his principal work location to Basel.

As well as Bau 1, there were an increasing number of competitions and smaller projects in operation. In the summer of 2012, we moved into our new offices in the picturesque St. Alban valley in Basel. Our team consists primarily of engineers, draftspersons, and site managers so that we are perfectly established for all tasks concerning sophisticated structural engineering. Since 2019, our long-standing employee, Lars Keim, has been Managing Director and Partner, and together with Martin Stumpf, has been managing our office in Basel.
Various first prizes are the bounty of numerous competitions, e.g. the DBSG (Department for Exercise, Sport, and Health at University of Basel) in Basel with Caesar Zumthor and Markus Stern, and the old Academy in Munich with the architects Morger and Partner.
We also pass our great interest in sophisticated construction engineering on to college students: Martin Stumpf has been lecturing to young civil engineers at the FH Nordwestschweiz (North Swiss Institute of Technology) since 2014.
We place a high demand on ourselves that we can explain our structures simply and comprehensibly to other planning participants at any time. We believe that this is one of the reasons why architects are very happy to bring us on board during competition phases.
In the selection of materials, we choose innovative and new materials such as ultra-high performance concrete, textile and fibre reinforced concrete, and high-tensile grades of steel as well as the classic materials such as concrete, timber, steel, ETFE, and textile membranes. Our commitment to sustainable building ensures the energy efficient quality of our projects and the implementation of decisive aspects of sustainability in the planning process. Furthermore, we have been actively advancing BIM projects for several years and we are deeply committed to interdisciplinary collaboration with other planning partners using the BIM method.

Another area of our operations is the provision of second opinions: We demonstrate optimization, and even cost saving potential for clients in their large and technically sophisticated projects. When providing a second opinion, we work cooperatively with the engineers who designed the concept we are evaluating.
