Key aspects of the program encompass:
At the upcoming 34th BBB Assistant Conference in Berlin, 2025, attendees will have the opportunity to learn about groundbreaking research in the field of construction and engineering. One of the presentations set to take place will be by Felix Ehmke, who will discuss his research project titled "Quality Assessment of Annular Gap Filling with Gravel in Mechanized Hard Rock Tunneling".
Meanwhile, another notable presentation at a previous event was delivered by Anika Häberlein, who presented a study on "Sustainability in Bridge Construction". This research compared the sustainability of different construction variants of an integral road bridge, with a focus on a 100-year analysis period.
Häberlein's findings revealed that steel-concrete composite bridges (SCC) outperformed wood-concrete composite bridges in terms of durability and lifespan. This is primarily due to the superior load-bearing capacity and structural performance of SCC bridges, which benefit from combining steel’s high tensile strength with concrete’s compressive resistance.
SCC bridges also exhibit higher resistance to environmental degradation compared to some traditional materials, resulting in enhanced durability over time. Additionally, reduced material requirements thanks to composite action lead to lighter structures and lower initial construction costs.
On the other hand, while specific 100-year data for wood-concrete composites is less abundant in the provided sources, wood-concrete composites generally offer a more environmentally friendly profile due to wood's renewable nature and lower embodied carbon. However, durability can be a concern because wood is more susceptible to environmental degradation unless properly treated and protected.
Felix Ehmke's project aims to determine the effectiveness of gravel filling and optimize bedding processes in mechanized hard rock tunneling. Pressure sensors are embedded in the outer side of the segments for accurate measurements.
The event, organized by the Construction Industry and Construction Management department at TU Berlin, includes presentations on themes such as sustainability, digitization, productivity, and communication. It is sponsored by various parties, with appreciation expressed for their excellent organization and inspiring days. The event offers additional highlights like a tour of the large construction site 'Fürst' on the Kurfürstendamm and culinary experiences.

The following presentation scheduled at the upcoming 34th BBB Assistant Conference in Berlin, 2025, will delve into the realm of environmental-science, specifically discussing the impact of technology on the lifespan and sustainability of construction projects through the use of steel-concrete composite bridges. Meanwhile, attendees might also find interest in scientific research on the environmental-science aspect of the gravel filling technique in mechanized hard rock tunneling, as presented by Felix Ehmke.
