The smooth and timely execution of construction projects without additional measures is a common goal for many project participants. Despite extensive research into analyzing the causes of deviations, planning errors are still a widespread topic in...

It has always been a goal of construction management research to improve the handling of construction projects. Within the framework of so-called „integrated project delivery“, project participants generally attempt to create a system that...

Cable-stayed bridges, celebrated for their architectural elegance and efficient design, are notable landmarks worldwide. However, they face structural challenges, such as sensitivity to asymmetric loads and the need for significant components. This...

This paper presents a method for optimizing the load-baring structure of high-speed railway bridges. Optimization is performed in terms of the required failure probability as defined in the relevant regulations, with the geometry of the bridge...

Bridge construction measures are primarily awarded based on their economic efficiency. Cost, time and quality criteria guide the planning and awarding of contracts. However, it is clear that sustainability must become the key criterion of...

The “Bankhaus am Theater” (bank building at the theater) in Aachen was built in the Wilhelminian period in 1907 and is listed as heritage building. From 2018 to 2022, it was expanded by a new concrete building, which cantilevers the historic...

Against the background of the high greenhouse gas emissions attributable to the construction industry, building with concrete, reinforced concrete or prestressed concrete in particular is facing significant challenges. The German Committee for...

The bond between steel and concrete is the essential basis for the functioning of reinforced concrete components. Among other things, it influences crack spacing and crack widths as well as the tension stiffening effect. Due to the time-dependent...

With fib Model Code 2020, new design rules for reinforced concrete structures have recently been published. For civil engineers, academics, and practitioners, the question arises of evaluating the new bond design models compared to their previous...

The Alster indoor swimming pool in Hamburg is known far beyond the borders of the Hanseatic city for its striking building shape. Its unusual roof, which was designed more than 50 years ago by our office founder Jörg Schlaich, makes it an...

Cities and communities across Germany are aiming to become climate neutral between 2030 and 2040. But what does that mean for the residential building stock? Is a corresponding energy-saving renovation possible or can the goal only be achieved...
