Our Profile

As independent consulting engineers for facade techniques we take over the planning of sophisticated facades through our specialized engineers.

Since founding in the year 2000, our staff has grown up to over 20 employees. Our offices are located in Bietigheim-Bissingen (near Stuttgart) and Berlin. 

Our company’s founders and engineers have all gathered years of experience working for well-known facade companies. This experience involves monitoring large-scale façade projects regarding all technical and commercial areas, as well as facade maintenance. 

With the relevant participation in a number of large-scale projects such as e.g. Potsdamer Platz Berlin, Olympia Stadium Berlin, we were able to gain excessive practical experience which has been of great advantage for us as technical planners.

Our engineers have an abundance of façade technical know-how and high levels of creativity accompanied by teamwork, practice, and pragmatic orientation.

Therefore we are in the excellent position to be able to develop and design individual, system independent and high-quality economical solutions for our clients until the execution on site has been carried out correctly and precisely.

Team and Equipment

Our highly motivated team includes

  • Facade engineers, facade technicians, and facade designers
  • Experienced facade project and site managers 
  • Authorized facade experts and facade inspectors
  • Assistants for project  management and administration

Professional equipment, IT, software, measurement devices - all state-of-the-art.

Our Contribution

Modern facades are required more than ever to be innovative and to fulfill a number of complex demands regarding building physics, technology, thermic, energy, climate conditions, as well as individual demands of a specific project. Additionally, facades are required to fulfill high standards in terms of quality, stability of value, durability, sustainability, and economic efficiency. 

As a result of the constant advancement of technology and science, technical, material specific and energetic knowledge has progressed as well, resulting in new solutions and possibilities regarding facade technology. 

Therefore, the range of applicable solutions regarding execution, materials and components is as extensive as it has ever been, and is most likely to increase in the future.

As a result of all these complex and varied conditions, the realization of multifunctional and sophisticated facades requires a considerable subject specific field, which demands specific and individual planning by competent and experienced engineers. This subject specific field is what we excel in.

We support the general planner and architect in close collaboration with the complete team of planners through the process of competent façade planning, beginning with first ideas, preliminary drafts, cost control, principle detail planning, and finally high quality execution on site.

Damages and defects are monitored and preventively averted during planning as well as during the execution. This benefits the client, all project participants, and the users.
