About

I am Managing Director and Co-Owner of BWK Engineers, an engineering consultancy specialized in MEP (TGA) design for complex building projects across Germany, Europe and Middle East. With a background in mechanical engineering, my focus is on delivering coordinated, BIM-driven engineering solutions that are technically sound and practical to execute on site. At BWK Engineers, we work across all HOAI phases, supporting developers, architects and contractors with reliable and well-structured MEP planning. Our approach is straightforward: – translate project requirements into buildable engineering solutions – ensure early coordination between disciplines – reduce risk during construction through detailed planning Our core areas include: • MEP / TGA design (HVAC, plumbing, electrical coordination) • BIM-based planning (Revit) • Design coordination and interdisciplinary integration • Support from concept design through execution In recent years, we have also been increasingly involved in technically demanding and mission-critical projects, including data centre developments, where reliability, redundancy and system integration play a key role. We are based in Frankfurt and Belgrade and operate on projects across Germany and Europe. Open to collaboration on complex and technically demanding projects.
