Digital Highflyer

At the Carlsberg City District project in Copenhagen, ZÜBLIN shows what digital tools can already do today.

The images that Tomas Miskinis creates out of many gigabytes of data on his laptop look like surreal artworks. Recognisable is the site of Carlsberg City District in Copenhagen, which looks like a huge gap between the surrounding brick buildings. Virtual structures in different colour can be recognised – future buildings, the subsoil or the course of pipes, as well as construction machinery such as cranes and excavators. But for Miskinis, as engineer and BIM designer at ZÜBLIN A/S in Denmark, his work is not about art. With these virtual building data models, he wants to improve the communication between the various project participants – and avoid collisions on the construction site.

Here you can see how 3D scans generated by drones can create digital models of the construction site and of future buildings, and how all those involved in the Carlsberg City District project benefit.

Carlsberg City District

A modern new district in a traditional place

Where the world-famous Carlsberg brewery had brewed beer for more than 150 years, a new city district will arise. Including, among other buildings, nine skyscrapers, two of them – the Dahlerup and Vogelius Tower – are being built by ZÜBLIN A/S. The contract also includes four adjacent buildings: Caroline House, Kjeldahl House, Forchhammer House and Djørup House.

A flight over the entire area takes about 15 minutes. Hundreds of pictures are made of the construction site.
The image data are used to generate three-dimensional models. The photographs are also used for the construction documentation and volume calculation.

ZÜBLIN Project Manager Svend Christensen says the work has become more intuitive through the use of digital tools.
The new district in Copenhagen owes its name to the Carlsberg brewery. For more than 150 years, the world-famous brewery brewed beer here. Now there arise apartments and restaurants.

Cooperation instead of Competition

During the Carlsberg City District project, the BIM tool Pix4D was used to help solve a particular geotechnical challenge: at the Dahlerup Tower and Caroline House, ZÜBLIN is working in direct proximity to its Danish competitor Aarsleff. Aarsleff had already installed ground anchors in the direction of the ZÜBLIN construction site, in an area of numerous underground pipes. To avoid any collisions, ZÜBLIN revised the original design on its construction site.

A process in which the two ZÜBLIN divisions Geotechnical Design and BIM cooperated – but also among competitors, as Ole Berard of the ZÜBLIN BIM team reports: “Aarsleff gave us access to its BIM model, from elsewhere we got the plans for the underground pipes. Together with our drone-made 3D scans, we determined the exact position of the ground anchors and pipes and changed our model accordingly. We adjusted the alignments and depths of our ground anchors and avoided collisions with those set by the competitor.“
