Thanks to rapid population growth, the transport infrastructure of the region known as the melting pot of nations had already begun to reach its limits in the 1970s. The new rapid transit concept, which connects the centers of the Twin Cities with one another, has helped ease the volume of road traffic. One aspect of this project is the particularly well-frequented West Bank Station. The architects at AECOM designed a solar protection façade from GKD metal mesh as a platform for public art. Nancy Blum, a very popular artist, critic and art lecturer in the US, then added an additional dimension to the metal mesh solar protection façade by eternalising the eventful history of the multicultural region in an artwork. An etching process was used to give the metal mesh panels an ethnic pattern that is reminiscent of the three regions where the immigrants originated from – Scandinavia, Asia and East Africa. GKD implemented this idea by using blasting media on the mesh to create the precise patterns produced by the artist. The durable patterns created using this method were instantly resistant to UV and severe weather conditions without the need for any special treatment. The interplay of the patterns with silhouettes of migratory birds typical of the area reflects the dynamic interactions of this region that is steeped in tradition. The mesh structure also prevents the two-storey, glazed railway station from getting too hot in summer. The transparency of the textile skin creates a pleasant atmosphere flooded with natural light. The mesh can also handle the region’s adverse weather conditions, such as wind, rain, snow or frost and offers protection against vandalism. Alongside the powerful functionality and high-grade aesthetics, the durability and lack of maintenance of GKD mesh were key factors for the architects.
