The construction of roads, railways, bridges, and supply networks requires data that reflects space, time, construction ground, operation, and lifecycle. In the Ask-the-Expert interview, Peter Rummel from Bentley Systems explains why digital twins, open standards, and AI are essential not only for planning infrastructure but for reliably operating it over decades.

Between Warsaw and Łódź, Port Polska is developing a new international airport linked to a high-speed rail and road network. The project is among the most ambitious infrastructure programs in Europe and is digitally organized from the start. BIM, shared data environments, and open standards are intended to bring together hundreds of project participants. In 2026, the country is the official partner country of BIM World MUNICH.

Hamburg Central Station is facing complex parallel construction projects. A digital twin supports efficient, digital multiproject management: 4D simulations identify spatial-temporal conflicts in ongoing operations and help resolve them. The semantic data model and its integration into the existing IT landscape also bridge the gap to seamless building operations.

BIM, Common Data Environments, IoT and connected building systems make construction projects more transparent and efficient. Every new connection also expands the digital attack surface. Using BIM and digital twins throughout a building's life cycle therefore means planning their protection from the outset. Cybersecurity is not a feature to add later: it is a prerequisite for reliable digital construction processes.

No trains have run on Berlin's Siemensbahn since 1980. Now the nearly 100-year-old line is to reopen, complete with listed stations, bridges and an 800-metre elevated viaduct. A digital model of the existing infrastructure, containing more than 300,000 components, provides the foundation. Combined with GIS, it supports planning far beyond the individual structure.

We are live! After months of ideas, discussions, planning, writing, technical work and plenty of challenges along the way, Built4Tomorrow has launched. Our new digital trade magazine connects the disciplines that already work together across construction and real estate.

Model-based planning has become part of railway construction, but BIM can only reach its full potential when real-time data is integrated. More efficient and resilient planning and control of infrastructure projects require a shift from static models to continuous support for live processes. Sensors, drones and AI provide a steady flow of information from the construction site.

Maintaining infrastructure such as ports and bridges is an increasing challenge for designers and operators. Germany's repair backlog, investment needs and sustainability ambitions call for new approaches. Modern sensors play a key role by recording structural conditions in real time and enabling more precise maintenance planning.
