Topping out ceremony at the infra-lightweight concrete project ‘Youth Club Betonoase’ in Berlin

November 8th, 2017, the topping-out ceremony took place at our project site for ‘Youth Club Betonoase’ in Lichtenberg district of Berlin. Together with architects Gruber Popp, schlaich bergermann partner have developed the design and construction documents after winning a design competition jointly in spring of 2016. The external walls and canopy roofs of the single storey building are constructed of infra-lightweight concrete with a density of only 700 kg/m<sup>3</sup>. Due to the low thermal conductivity, the structural and building physics requirements can be fulfilled with a monolithic concrete structure with external walls of 50 cm thickness. The term infra-lightweight concrete stems from the fact that – similar to infrared radiation – with its low density it lies beneath the spectrum which is covered by current building codes. A special approval process was required with numerous structural tests to confirm the strength of the members.

 

The client, Lichtenberg council, pushed the innovative pilot project ahead together with the design team, check engineers, external experts and the approving authority.

 

For us, the project is an important milestone in establishing monolithic design in the industry. The opening is envisaged for summer of 2018.
