Renovation of City Airport runway

Mannheim, Germany / 10.2025 - 10.2025

In just two weeks, PORR Verkehrswegebau carried out extensive renovation work on the runway at City Airport Mannheim. The client was Rhein Neckar Flugplatz GmbH, which set the highest standards in terms of quality, adherence to deadlines, and minimal disruption to operations. Thanks to precise planning and efficient implementation, the project was completed on schedule and flight operations were quickly and safely resumed.

The image shows a large-scale road construction site where a new carriageway is being built. Several yellow asphalt pavers are working side by side, applying fresh asphalt to the wide surface. In front of and behind them, rollers are in use to compact the surface. Numerous lorries deliver the hot mix directly to the machines, while construction workers in high-visibility vests supervise and coordinate the work. Light smoke rises above the pavers, indicating the use of hot material. The construction site is located in open countryside with green fields and agricultural land in the background. Industrial facilities and a few buildings can be seen on the horizon.

Successful complete renovation of the runway in a short period of time

As part of the project, around 44,000 square meters of asphalt were laid in multiple layers and an equally large area was cement-stabilized. In addition, there were 35,000 m³ of earthworks, 2,500 m of sewer construction, 15,000 m of cable protection pipes, and 5,000 m of markings. The work was carried out within extremely tight time frames, as flight operations were to be affected as little as possible. This required precise timing of all trades, reliable logistics, and maximum material availability. In addition, strict technical regulations such as ZTV Beton-StB and the FGSV information sheets for flight operation areas had to be complied with.

Challenges in the sensitive airport area

The coordination of safety-related processes in the sensitive airport area, weather conditions, and the guarantee of absolute quality and evenness placed special demands on the PORR Verkehrswegebau team. An environmentally friendly approach was achieved by reusing the existing material: the existing asphalt pavement was broken up on site, reinforced with cement and used as a new substructure – this reduced transport distances and almost all disposal quantities.

Digital control for maximum efficiency

Another success factor was the use of the digital project management tool Smart Site One (SSO). This tool enables precise control of all asphalt processes in real time – from mix logistics and temperature control to complete documentation. Real-time data on delivery quantities, temperatures, and rolling passes enabled processes to be optimally coordinated, downtimes to be reduced, and installation quality to be reliably ensured.

With a high level of expertise in runway rehabilitation, a well-thought-out scheduling and logistics concept, and transparent, cooperative collaboration, the PORR Verkehrswegebau team set new standards in quality and process reliability.

What ultimately counts in the construction business is successfully completed projects. PORR has many of these.

The image shows a construction site scene in which three construction workers in safety clothing and blue helmets are working together to place a large black plastic element into a prepared pit. The element is lowered precisely using chains and a crane attached to a yellow construction vehicle. The workers are wearing high-visibility vests in yellow and orange, which ensures good visibility.

In the foreground, a person wearing high-visibility safety clothing, including a yellow safety jacket and orange work trousers, stands with their back to the camera. The person is working directly on a large asphalt machine, which can be seen in the centre of the image. The machine is painted turquoise and grey and is being operated by another person sitting in the driver's cab.
