Kineum is being built with low-carbon concrete – bringing life and activity to the district of Gårda.
The old working-class district of Gårda in central Gothenburg has undergone a transformation in recent years. From being filled with the typical Landshövdingehus (traditional three-storey workmen’s dwellings which are typical for Gothenburg) to now being one of the city’s most office-dense areas. Here, the old houses now coexist with new skyscrapers.
In the middle of Gårda, between the E6/E20 highways and Nya Ullevi, stands the newly inaugurated Kineum – a 27-story building that houses, among other things, office spaces, bars, and restaurants. It also includes the hotel Jazy’s, which with its 233 rooms and pool club occupies 17 floors of the building.
Environmental benefits of low-carbon concrete
Kineum was developed by NCC in collaboration with Platzer. Early in the project, the decision was made to construct the building using low-carbon concrete to reduce CO2 emissions. Together with C-lab, Thomas Concrete Group’s center for research, development, and laboratory testing, they developed Thomagrön Plus. This concrete features a has reduced amount of cement content, replaced by alternative binders, resulting in a carbon dioxide saving of 200 tons and a carbon footprint reduction of 39 percent compared to traditional concrete.
A major challenge of the project was due to the building’s location in central Gothenburg, which complicated logistics and required careful planning. The project faced several challenges. Another challenge was casting the 3.5-meter thick foundation slab, which required 1,300 m³ of concrete and took 20 hours to complete. Another challenge was the slip casting of the lift shaft, where a truck with concrete was delivered every hour for over a month. These challenges were successfully addressed through great collaboration between Thomas Betong and NCC, along with well-planned logistics.
