K8

K8 – Our 3rd project featuring Closed Cavity Façade elements delivered for Skanska.

K8, a mixed-use office development in Stavanger, Norway, is the third project we have delivered to feature Closed Cavity Façade (CCF) elements. Successfully completing this project has deepened our experience with this innovative technology and further strengthened our long-term partnership with client Skanska.

K8 is a 16-floor tower that contains 15,000 m² of space for offices, restaurants, exhibitions, and conferences. It offers a creative work environment for both occupants and users and is a significant contribution to the city‘s urban development.

The façade design is a composition of slim vertical aluminium and glass panels that offer increased daylight to over 600 workspaces. For this project, we have delivered a 6,670 m² façade composed of both Closed Cavity Façade (CCF) and Single Skin Façade (SSF) elements. One significant challenge was meeting the strict testing requirements, which included air tightness (EN 12152) and water-tightness (EN 12154 and EN 12155), as well as a special fogging test required for the CCF elements. A section of the CCF also required a fire rating of EI120, and as modular façade systems do not meet this rating, the team worked hard to find an overall solution. All of these tests were successfully completed in 2022.

Another notable design and installation challenge was the trapezoidal cantilever on the SSF elements and the 16th-floor trapezoidal and corner elements. These complex features contribute to the distinctive character of the K8 façade.

Another noteworthy aspect of the K8 project was the team‘s exclusive use of model-based definition when delivering information for production. This was our first-ever project completed using this approach.

With installation completed in December 2023, the K8 project is now finished and the building is already open for use, including the stunning top-floor restaurant. Successfully delivering K8 marks another milestone in our long-standing relationship with Skanska, with whom we have worked on multiple projects in the Nordics.
