CASE STUDY: KAMPSTRASSE 47
DRESDNER BANK, DORTMUND

In 2016 our team was invited to a competition to create a BIM Model of the former Dresdner Bank headquarters in Dortmund which due to our knowledge of the Allplan BIM functionality and our experience in 3D architectural modelling, we eventually won the competition and started the challenge.

THE BUILDING




The former Dresdner Bank headquarters in Dortmund is under historical protection, even though it was designed just 40 years ago by the famous German architect Harald Deilmann.


Due to its contemporary, pop-art inspired architecture, in 2001 Kampstraße 47 was accepted in the list of monuments of the city of Dortmund and is protected since then.


Its impressive concrete façade is timeless beautiful and was modelled by us in all details. Also the sheer size of the object-it has four underground parking levels- makes it a real reference project for us.

WHY BIM?

 

 

In our case the building will be subdivided and rented out to different companies. During the renovation phase exact quantities are required to receive the lowest possible offers. Later on, the data will be used for facility management purposes, like rental- or relocation management, fire protection, or for interior design.

SOFTWARE
 

 

 

We were using a very powerful Software, that allowed us to manage the huge amount of data. The first step was to set up a proper building structure with the “Building Manager”. Through the architectural functions of Allplan we defined then the intelligent elements like Walls, Slabs and columns. Since Allplan creates parallel to the BIM model also an exact working drawing of each floor, it was easy for us to crosscheck the results with the original plans at any time.


The model was then saved on the BIM plus platform which is actually a cloud server and allows all participants to access the model. The data is saved there in the neutral IFC format, so that other planners like HVAC – or Construction engineers can add their data in any BIM compatible format.

Structure – Detail level 1:1

The detailed level of the structure model is 1:1. The building consist of underground garage levels and 7 office floorplans. Outstanding space is the atrium with a massive ladder, which looks like its floating. Another element is a passage through the building which looks like a street with outdoor lamps and plant pots. It’s surrounded by pavilion type volumes that lead to the 2nd floor and a big terrace.

Concrete Facade  – Detail level 1:1

The detailed level of the structure model is 1:1. All the concrete panels were prefabricated and marked with an identity number. The elements around on the 1st floor define the atrium and make the former bank an unique building. Luckily there was a typical panel, but also more than 70 single concrete elements with different double curvature of the geometry.

Metal Facade  – Detail level 1:1


The detailed level of the structure model is 1:100. Some of the old drawings were missing and part of the façade was modelled based on pictures from the site visit. It’s designed in anthracite color and serves as a background of the white concrete facade. The metal façade serves as a connection between the building and the visitors, defining all the entrances
