The result is a modern green building that is tailored to the requirements of the new users. Due to the previous use of the site by an asbestos cement plant and a plastics factory, the entire area was heavily contaminated with asbestos. The mineral fiber asbestos is considered carcinogenic and therefore had to be handled with particular care. In addition, there was a local entry of

mineral oil hydrocarbons (MKW). "We had to take both factors into account at the start of the project and developed appropriate soil management concepts for disposal," explains Stefan Bohn, Managing Director at Panattoni Germany. Once the concepts had been agreed with the responsible authority in Dettelbach, the project developer began with the practical implementation.

Asbestos waste becomes sustainable frost protection

As part of the site preparation, visible asbestos fragments were first removed in compliance with the relevant regulations (occupational health and safety, TRGS 519). When collecting the fragments, the employees wore protective equipment to avoid contamination from high fiber concentrations. The piles created from the removed topsoil were inspected again. It was no longer possible to visually distinguish between piles containing the smallest fragments, which is why the material was disposed of properly.

Panattoni then built on the construction site areas approved by the expert. This also reduced the risk of asbestos residues being released, as the potential residual risk from asbestos fibers can be classified as very low due to the sealing of the hall and parking areas. The project developer applied an additional layer of soil in the unsealed areas where the removed piles were reinstalled in order to completely rule out any risk of danger here as well.

Following the unsealing, Panattoni also assessed the local PFC damage. Groundwater monitoring was then carried out in order to be able to react immediately in the event of any future contamination. The deconstruction began with the gutting of the building and the removal of pollutants. Pollutants such as asbestos, polycyclic aromatic hydrocarbons (PAHs) and artificial mineral fibers (AMF) were professionally removed and disposed of. The demolition of the buildings above ground then began, followed by the floor slabs. Hazardous substance tanks on the site were also removed. Non-contaminated mineral material from the floor slab and other concrete parts were broken up and crushed. The remaining mineral demolition material was applied to the area as a frost protection layer. This allowed Panattoni to use 10,000 m² of recycled material for the new building. In addition to the project developer's green building strategy, this is another sustainability aspect of Panattoni Park Würzburg Ost.

Cooling with solar energy

Panattoni was able to attract two well-known tenants for the site: Following the disposal of a total of 576 tons of asbestos, the revitalized site provided sufficient space for Dachser's new logistics center and s.Oliver's distribution center. Dachser needed a second location near Würzburg in order to be able to process transport orders in the Mainfranken region. The business location of Dettelbach was the obvious choice due to its central location and good transport connections. Depending on customer requirements, the goods are now stored, picked, packed and finally transported to the recipient in Dettelbach. As Dachser uses one of the warehouse units for food logistics, a cooling system was integrated. This allows the hall to be set to various desired temperature ranges. The energy required for this is generated by a photovoltaic system on the building's own roof.

The company s.Oliver is using its new branch as a central distribution warehouse for the European market in order to meet the growing demands of e-commerce. The new logistics center therefore has special intralogistics facilities such as a pick tower and a hanging goods warehouse. Individual automation solutions such as an automatic returns buffer and a bag sorter also speed up the warehouse processes.

Interplay of high-tech and green building

Panattoni attached great importance to the sustainable development of the facility. The building, which is designed to be highly reusable, is equipped with a 1.4 megawatt photovoltaic system and electric charging stations for cars and e-bikes. Roof-covered bicycle and smoking shelters as well as wellbeing areas ensure a natural feel-good atmosphere. A pond with biological filtration, unsealed outdoor areas and water-bound paths promote native flora and fauna. Wildflower and orchard meadows contribute to the preservation of biodiversity, as do nesting aids for building breeders and bats. A replacement habitat was created on an area of 9,300 m² for the sand lizards that used to live on the site. With these and other sustainability measures, the logistics real estate developer achieved the DGNB Platinum standard for the s.Oliver hall and all requirements for DGNB Gold certification were met for the Dachser hall.

As a result, it has been possible to conserve resources and modernize already sealed areas: "In close cooperation with all project participants and representatives of the district of Kitzingen, we have transformed a brownfield site that had been contaminated for years into a sustainable and modern logistics center," says Bohn. "The development of Panattoni Park Würzburg Ost shows how an environmentally and socially compatible realization of a logistics property can work." This benefits both the municipality and the tenants. The establishment of the two companies also strengthens the economic power of the district of Kitzingen.
