Ing. Stefan Linder
Ing. Stefan Linder supports private clients and professional partners with building-services challenges — from the first system decision to project delivery.
The focus is never a particular manufacturer, but a solution that works technically, financially and operationally.
Experience in design, practice and technical assessment As a generally sworn and court-certified expert, Ing. Stefan Linder combines many years of practical experience with independent and particularly thorough technical assessment. This understanding of technical relationships, interfaces and potential risks also informs his consulting, design and project support.
Our commitment
Three standards for every recommendation
Independence
Systems and products are evaluated against the actual requirement, not a sales agenda.
Responsibility
For us, design does not end on paper. Buildability and operation are considered from the start.
Collaboration
An interface between technology and the project
For installers, engineering practices, plant contractors and developers, we take on clearly defined design and coordination packages or support the overall project.
Need an independent technical assessment?
We assess the situation and give your next step a technically robust foundation.
