Challenging tunnel construction project in Copenhagen implemented using PERI solutions Press Release Challenging tunnel construction project in Copenhagen implemented using PERI solutions Nordhavn Tunnel, Copenhagen, Denmark The Nordhavn Tunnel will provide a new link between Copenhagen city centre and the harbour. The unique location and complexity of the 1.4-kilometre-long structure pose significant challenges in terms of organisation and execution. PERI is supporting the project with sophisticated formwork and access solutions, as well as comprehensive technical support, thereby ensuring safe, continuous and predictable construction progress. Tunnel construction in the heart of the city The Nordhavn Tunnel will run beneath Svanemølle Harbour and the Kalkbrænderiløbet waterway and shipping channel, providing a direct link between the districts in the north of Copenhagen. This will bring the Nordhavn district, a key urban development area, closer to the existing urban structures. At the same time, an underground transport link is being built, which will relieve pressure on aboveground traffic routes and enable people to travel through the city more quickly. The new infrastructure comprises two separate tunnel tubes with a total of four lanes and will ensure smooth and safe traffic flow in future. The Nordhavn Tunnel is being constructed using the cut-and-cover method, which allows for a phased and precise implementation. At the same time, it offers good accessibility and safe working conditions – a key advantage in a challenging, inner-city environment. PERI systems ensure uninterrupted construction progress To ensure the tunnel construction project progresses efficiently, PERI is supporting the project with a bespoke combination of various formwork, access and load-bearing systems. Eight VTC Tunnel Formwork Carriages are being used for the in-situ concrete construction of the tunnel. These enable repeatable concreting operations with high geometric precision and reliable load transfer, resulting in a smooth and efficient concreting process. In technical buildings and pumping stations, MAXIMO Wall Formwork ensures a high degree of flexibility for varying geometries, as well as a consistently high-quality concrete finish. Bottom plates and slabs are formed and securely supported using DUO Universal Formwork and MULTIFLEX Girder Slab Formwork in combination with MULTIPROP Shoring Towers. LGS Working Platforms spanning the excavation pit allow for safe and space-saving routing of service lines. The system concept is complemented by PERI UP Stair Towers, which provide safe access to the excavation pit. Technical support assists with project management and execution PERI’s technical support team has been involved in the project from the outset and maintains close, ongoing contact with the project and site management teams on site. On this basis, the systems are tailored to meet specific requirements and are backed up by structural calculations and project-specific technical support throughout the planning and implementation phases. Close communication helps ensure that the project progresses smoothly throughout all stages of construction. Comprehensive technical documentation of the individual planning stages also helps the contractor to carry out the project in a structured and efficient manner, and provides valuable guidance even in later stages of construction. The outcome is a comprehensive solution in which high-performance systems, technical expertise and project support complement each other seamlessly. About PERI With sales of € 1, 862 million in 2025, PERI is one of the leading manufacturers and suppliers of formwork and scaffolding systems in the world. The family-owned company, with its headquarters in Weissenhorn (Germany), a workforce of around 10, 000 employees and more than 140 warehouse locations in more than 60 countries, provides its customers with innovative system equipment and comprehensive services relating to all aspects of formwork and scaffolding technology.
