The approximately 100.000 m2 site of the former German National Railway Repair Works (RAW) in Potsdam was to be prepared for prospective construction. For this purpose, partially basement buildings and warehouses with contaminated structure (i.a. asbestos, KMF, roofing felt, MKW) had to be demolished and the area be fully developed. Large quantities of construction waste containing hazardous substances had to be treated and partially reused. In the area of a listed hall, the reconstruction of oil damage in the soil and groundwater had to be carried out in accordance with a public-law restructuring contract
