01 About

From BIM model to digital asset lifecycle.

Civil engineering · BIM · Code

BIM is more than a planning tool. In the current DB Infrastructure strategy it has become the foundation of a fully digital asset lifecycle — from strategy and planning through construction to operation, maintenance and reinvestment. That intersection is where I work: where model-based planning has to translate into reliable operational data — and where “build digitally first, physically second” becomes the operational standard.

In large rail infrastructure projects of DB Region East, I led model coordination, EIR, CDE workflows and quality assurance across the owner, design partners and contractors. My focus: models that are not just geometrically clean, but that carry through as a coherent information basis for every downstream phase — construction, handover into asset operation, digital twin, lifecycle analytics.

I see myself as a civil engineer with deep BIM expertise who coordinates interfaces and solves problems — not as a tool specialist. Methods and software are means to an end. When standard tools fall short, I build my own. What matters is measurable impact: continuous data chains instead of broken handoffs, faster alignment, stronger schedule reliability, and trustworthy information across the entire asset lifecycle.

Modernisation of Berlin-Westend station on the Ringbahn — accessibility upgrade, bridge replacement nearby, platform and access renewal.

Potsdamer Stammbahn

Corridor · i2030

Potsdamer Stammbahn + Berliner Innenring

Reactivation of the historic Stammbahn from Griebnitzsee to Potsdamer Platz as a double-tracked, electrified regional line, plus expansion of the southern Berlin Innenring to relieve the north-south main line.

S21 Berlin

S-Bahn Expansion

S21 Berlin

New north-south S-Bahn line through central Berlin: Nordring – Hauptbahnhof – Potsdamer Platz – Yorckstraße – potentially Südkreuz. Section 1 (line S15) entered service June 2026.

Station on the Berlin Northern Railway at the edge of the Berlin outer ring — interchange between S-Bahn and regional services, modernisation of the station and turning facilities.

Eisenbahnbrücke Wollankstraße

Station · Bridge

Bahnhof Wollankstraße

New railway bridge over Wollankstraße in Berlin-Pankow. Bridge replacement and noise protection for the S1 and the regional/long-distance line heading north.

05 Tools

Tools I’ve built.

Alongside the rail infrastructure work, I build tools that make BIM workflows faster and more transparent — from an AI assistant to a browser-based 3D model viewer.

BIM Web Viewer

Web · 3D

BIM Web Viewer

A from-scratch 3D BIM viewer in the browser — React, Three.js and a custom pure-JavaScript IFC/STEP parser. Orbit controls, model tree, visibility toggles, section clip plane and a properties panel.
