Oberhausen: CENTRO Oberhausen

CENTRO Oberhausen
CENTRO Oberhausen

Dorsch was commissioned by a firm of international property developers with the design and supervision of an urban redevelopment scheme involving mixed commercial utilisation on a former industrial site (disused steelworks) near the centre of Oberhausen in the state of North-Rhine Westphalia. The first development phase embraces the following buildings and facilities: shopping mall on two levels with sales area of 70 000 sqm, walkway with adjacent multi-purpose development including a cinemax cinema, a concert hall with 10 000 seats, 8 multi-storey car parks with space for a total of 10 000 vehicles, a central square, artificial streams and ponds covering 13 000 sqm as well as the integration of the entire site into the surrounding urban infrastructure – except for the necessary construction of new by-pass roads and of a public transport link with halt inside the project area.

Among the particular difficulties encountered were:

  • high water table
  • stipulations concerning surface water drainage
  • refilled, partially contaminated subsoil
  • partial filling of artificial surface waters with rainwater
