We have had the opportunity to interview Thomas Holmqvist who is contractor manager at GlasLindberg, about their project OAS in Malmö. OAS is an office building in central Malmö and Thomas talks about, among other things, the beautiful facade with fish scale pattern/herringbone pattern and what they have done to succeed with all details and transitions.
Please tell us a little bit about the project and your work with OAS.
It has been a good collaboration with various actors from the start, says Thomas. “Already at an early stage, we received an invitation from Skanska to participate in the project regarding the glass contractor”, he explains. We see a great advantage in this way of working, not only for us at GlasLindberg but for the whole glass contractor’s implementation in collaboration with Skanska and other subcontractors who affect the implementation in place, he continues.
Were there any particular challenges with the project that stood out and how did you solve them?
There were some challenges with the project that GlasLindberg solved in creative and well thought ways. The beautiful façade with its fish scale pattern lies as an outer shell in the concrete façade, Thomas explains. As the green surface layer in concrete is relatively thin, it was of the utmost importance to review all details in the project. This applies both to door/window sections in system SAPA 1086/2086 and façade sections in system SAPA 4150. Attachment points must be positioned correctly to avoid splitting in the exclusive shell façade. The transition and details don’t always look the same to give the building a more interesting expression, parts of the façade sections have for example superimposed frames in two different profile depths of 120 and 300 mm to create exactly this effect, Thomas further affirms. Here, we have put in a solid amount of work in the planning to refine the details and create transitions with hidden fastenings where the entire frame is completely connected with the façade sections, he describes. The façade facing the interchange, also doesn’t have the usual 90-degree corner, but breaks in two steps with open angles of 117 and 153 degrees. The façade sections in these corners flow freely without underlying vertical profiles with vertical joints between the glass to bring as much daylight into the building as possible. In order to meet the tough requirements for light transmission and solar heat load, we have worked with different types of solar protection glass depending on where in the façade the windows and façade sections are located, Thomas further explains. Where the requirements for sun protection are the lowest, we have supplied sun protection glass of the type 70/35 and where the requirements have been higher, it has been SNX60 instead, he concludes.
Is there anything in the project that you are particularly proud of?
Thomas explains that he is particularly proud of the façade and the partnership with Skanska. “The outcome of the above has been very good and I think the result speaks for itself,” he claims. The expression in the façade facing the big interchange is experienced as very exclusive and shines shimmering green in the afternoon sun, while the transition to the slightly recessed upper floors with a lighter wooden façade breaks the pattern. Thomas continues “I would also like to mention the good collaboration with our costumer Skanska in Malmö, which has been a contributing reason for the beautiful result.”
What is important to consider when choosing materials and how did you integrate sustainability in the project?
”We at GlasLindberg are actually a bit spoiled as for a few years now we have had the privilege of working with an aluminum construction system that has one of the market’s lowest carbon dioxide footprints in CIRCAL 75R”, Thomas says. Being able to be an active part when it comes to the increasingly tangible work of protecting our environment feels inspiring, he continues.
Which SAPA products have been used?
The SAPA-products that have been used are SAPA 1086/2086 and façade parts in system SAPA 4150 and also internal fire parts in system 2086 and class EI30. In the project we have also delivered internal steel parts on the floors where there are requirements for both fire class EI30 and burglary protection in the form of RC3, Thomas explains.
