A new city district is being created in the south-east of Amsterdam. As part of the SPOT Amsterdam urban development project, an office-laden location in the Amstel III district is being transformed into a lively and mixed neighbourhood for living and working. Sustainable energy supply is part of the concept, so, in collaboration with the Dutch project developer BLK Projects, Schletter mounting systems are being installed on the striking residential towers of the new district at heights of up to 110 metres.

“SPOT Amsterdam is one of the most exciting urban development projects in the Netherlands,” says Gaston Steijns, Sales Manager for the Belgium, Netherlands and Luxembourg regions at the Schletter Group. “In this respect, it is of course great that we are making a contribution to supplying the new neighbourhood with sustainable energy with our mounting systems.“ The new district, due to be completed by the end of 2025, consists of around 1,100 flats, 13,000 square metres of office space, and 4,000 square metres of space for shops, restaurants, and sports facilities. The silhouette will be characterised by several modern residential towers with heights ranging from 20 to around 110 metres, with PV systems installed on six of them.

The Schletter FixZ-15 system was used for this project. The high demands on statics and safety, as well as the high wind loads, played a major role in the choice of system. “Due to Amsterdam’s proximity to the sea, the wind loads are particularly high, and even more so at a height of 110 metres,“ emphasised Steijns. “The system must therefore be particularly stable and safe without overloading the building statics.“ Made from high-grade aluminum, the FixZ-15 offers superior stability and smart aerodynamics while remaining lightweight. It was designed and planned with the help of the Schletter planning tool. While many calculation programs on the market assume a preset standard height of 10 metres, the Schletter tool requires the actual building height to be entered.“ At 110 metres, the wind conditions are completely different to those at ground level,“ explains Steijns. “This was automatically taken into account while planning with the tool.“

In addition to the statics, precisely planned logistics are also crucial for the project. Many trades are involved in the major construction site, including companies that provide cranes and lifts to enable access to the roof. This means there is only a short timeframe for delivery and installation.  “You can’t afford delays in delivery on a complex project like this,“ emphasises Steijns. “Our colleagues deserve huge credit for planning the delivery and processing from our logistics locations perfectly.“ The Schletter Group has been working successfully with BLK Projects for several years. The two companies have, among others, realised the RAAKS and Het Dok construction projects in Haarlem and Ijmuiden respectively. “Working with Schletter has been a seamless experience, especially on high-stakes projects like SPOT Amsterdam,” says Bas Kolf, Director at BLK Projects. “Their expertise in designing systems that withstand unique wind and structural requirements has been invaluable, ensuring both stability and ease of installation, and their commitment to precise logistics also means we can rely on timely delivery, which is critical for complex developments like these.”
