UKR screed-covered underfloor duct systems with two or three sections are used when laying large quantities of cables and lines in office buildings, in the industrial sector and for technical building services. The duct systems consist of a base, a dummy cover and one or two separating strips. The bottom parts are fixed to the raw slab using the separating strips before the screed is applied and are securely closed with the suitable covers after the cables have been inserted. The products compensate for structural tolerances and can be used flexibly and regardless of the room’s purpose and screed type.

Airport Frankfurt
With almost 60 million passengers (2023), Frankfurt Airport is Germany's largest and Europe's sixth largest airport. In 2026, passenger numbers, which have fallen due to the pandemic, are expected to return to pre-crisis levels (~70.5 million) and continue to grow from then on.

Extension of the subway line U5
For decades, the current U5 subway line connected the eastern city center with the east and northeast of Berlin. Plans to extend the line to the west date back to the 1970s, but it was only with the reunification of Germany that these could be realized.

Commercial/office building
EDGE East Side Tower
The Berlin skyline is growing and another building was added in November 2023. With the 142 m high EDGE East Side Tower Berlin near ‘Warschauer Brücke’, one of Berlin's tallest buildings was built in just under 4 years. Particularly striking: the staircase-like curtain wall with almost complete glazing.

City S-Bahn S21 at Berlin Central Station
Berlin's main railway station is to be better connected to public transport. This is the goal of the construction of the new S-Bahn line S21, the so-called City S-Bahn. This line, which runs from north to south, connects the northern stations Wedding and Westhafen directly with the Central Station.
