On the 19th of February, Perstrup signed an order of almost 25,000 m2 SL-decks for 3 towers located in the Danish city of Esbjerg. The project has been designed by the Danish architect firm, Bjarke Ingels Group (BIG). BIG is perhaps the most well-known Danish architect company practicing today and stands behind famous projects such as Google Headquarters, 2 World Trade Center, Lego House and the Hyperloop One in Dubai.
Esbjerg Towers consists of three 57, 35 and 23-meter high towers and will contain app. 265 student homes and 135 hotel apartments. All towers consist of a circular core with triangular balconies on the outside and elevators and stairs in the middle of the building.
Perstrup won the entire precast contract based on a solution with “pizza-shaped” SL-decks spanning from facade to inner core. This solution eliminates all on-site casting and ensures a 100% precast slab structure, resulting in a significantly lower construction time. Another benefit of the solution was the possibility of replacing the many load-bearing walls separating each apartment with cheaper non-load-bearing walls. Besides reducing the wall costs, this solution also provides a lot of flexibility for changing room divisions later on.
Last month, Perstrup won the contracts for a number of other large residential projects including three big apartment towers in Copenhagen. More than 1,000 apartments are currently being made with SL-decks.
