About Me
Jan Sigrist – BIM Specialist, Lecturer, and Founder of Bimatic
From Foundation to Automation
Innovation Through Fresh Perspectives
Since May 2025, I have been working as an independent BIM specialist with Bimatic GmbH. My approach: From surveying through BIM to IoT integration – a holistic view of digital transformation in infrastructure construction.
What sets me apart: 14+ years of experience from surveying to BIM automation. The combination of practical project experience at Rhomberg Sersa Rail Group and academic expertise as a guest lecturer at FHNW. I know the challenges of daily project work and develop solutions that really work.
Core competencies: AI integration (Anthropic Claude, OpenAI), IfcOpenShell, Blender, Python, Dynamo, Grasshopper, Autodesk Civil 3D, Revit, Solibri, NavisWorks – from open-source to enterprise solutions, enhanced by cutting-edge AI technology.
AI & LLM Integration
AI-optimized workflows with Anthropic Claude and OpenAI. Custom bot development, prompt engineering, LLM-assisted script generation for BIM processes.
BIM & CAD Expertise
IfcOpenShell, Blender, Solibri, Revit, Civil 3D, InfraWorks, NavisWorks. Specialization in infrastructure, civil, and building engineering.
Automation & Development
Python, VBA, Dynamo, Grasshopper. Development of customized scripts and workflows to increase efficiency in planning processes.
Geomatics & Surveying
14+ years of experience in surveying, GPS, UAV, OpenGeodata. Solid foundation from surveying to 3D modeling.
Practice + Academia + Partnership
Project experience at Rhomberg Sersa, teaching at FHNW, professional Hexagon partner for Cyclone3DR and Leica Geosystems.

My Philosophy
Holistic Approach
BIM is more than software operation. It's about the entire process: From precise surveying through BIM modeling to integration with IoT data for digital twins. I guide you through the entire digitalization process.
Practicality Over Theory
Solutions must work in daily project operations. Through my experience at Rhomberg Sersa Rail Group and AFRY, I know the challenges in large projects: time pressure, capacity bottlenecks, complex requirements. My solutions are field-tested and directly implementable.
Efficiency Through AI & Automation
Repetitive tasks tie up valuable capacity. With AI-optimized workflows (Anthropic Claude, OpenAI) and custom Dynamo and Grasshopper scripts, I intelligently automate processes. Custom bots generate code, optimize workflows, and create space for the truly important planning tasks. This saves time, reduces errors, and exponentially increases productivity.
Knowledge Transfer
As a lecturer at FHNW, knowledge sharing is important to me. I offer not only services but also training and workshops – so your team can work independently and benefit from BIM competence in the long term.
