In October, we already reported on how the first two core sections seemed to have appeared from nowhere. Because the towers were built using a method known as slip forming, construction took only two months in total. ‘You can actually best compare this slip forming with a mould in which you pour concrete from the top whilst you place the reinforcement in the formwork’, explained Henry de Koning, planning engineer at G&S Bouw at the time. The four towers are now in place and the expert team brought in specially from Austria have returned home.
The towers will not remain visible. ‘Their function is to support the steel covering that gives the landscaper its look’, says De Koning. ‘The towers are actually a bit like a skeleton that, together with the foundations, forms the base on which the rest of the structure rests.’ The Tripolis Park team are currently hard at work on this steel structure. ‘The steel columns and girders are being manufactured in the factory like pieces of a puzzle before being assembled by the builders on site and attached to the towers.’ In the office building, the four towers will serve as lift shafts.
The landscraper is a completely new building on Tripolis Park and supplements the three existing listed buildings that have been undergoing renovation since March 2020. The landscraper will be a rectangular building that merges with two of the existing Tripolis buildings, forming a bridge between them. The ‘horizontal skyscraper’ also serves as a sound barrier separating the Tripolis building and the residential district behind them from the A10. In the future, the landscraper will accommodate a mixture of start-ups, scale-ups, and large companies, including Uber. There will also be hospitality venues and all of them buildings will have green, public roofs.
The existing Tripolis towers
The existing Tripolis buildings (200 and 300) by architect Aldo van Eyck are being redeveloped in such a way that they fully meet the stringent requirements of future office users. That means they will be packed with smart technology to make the buildings sustainable for the users working at the innovative companies that will be based there. The developer Flow Development has now started work on two of the three buildings. These buildings and the landscraper are scheduled for completion in mid-2022. The third Tripolis building – building 100 – will be transformed into a residential building with affordable rental apartments at a later stage. These plans are still being developed.
The redevelopment of Tripolis Park is not an isolated project and is part of a bigger plan for Verdi. Verdi is the area between Amstelveenseweg, de Schinkel and the Nieuwe Meer lake. In the years ahead, we will be connecting, consolidating, and making it greener. In the eastern part of Verdi in particular, we intend to build housing, amenities, and offices. In the western part, the focus will be more on green areas, water, sport, and recreation. Subplan 2 for this development is available for consultation until 25 November 2020.
