CO₂-reduced concrete monitored at Berlin’s EDGE Friedrichspark

On the site of Berlin’s former Wriezen train station, the EDGE Friedrichspark development is setting new standards for sustainable construction. The commercial complex, led by developer Edge and built by Züblin, features a 100% renewable energy concept and extensive use of low-carbon concrete supplied by Spenner Herkules — with Doka providing both formwork systems and real-time monitoring technology.

To reduce embodied carbon, Züblin is using approximately 12,000 cubic metres of clinker-reduced concrete, cutting CO₂ emissions by around 65% compared with conventional CEM I mixes. As these new formulations develop strength more slowly, Doka’s Concremote sensor system is being used to continuously monitor temperature and compressive strength during curing. The live data enables the construction team to determine safe stripping times, ensuring the material’s performance while maintaining efficiency and cost control.

Joachim Immerz, managing director sales at Doka Deutschland, said: “Decarbonisation is a collaborative effort that requires cooperation from developers, contractors and service providers. As one of the world’s leading formwork manufacturers, we operate at the interface between formwork and concrete and can make an important contribution to sustainable construction.”
