REDEVELOPMENT OF A DISUSED INDUSTRIAL SITE Neighbourhood development: Bringing people and nature back into town Drees & Sommer is successfully supporting the client with the PHOENIX See (Lake PHOENIX) project in Dortmund, which involves the redevelopment of a former coal mine site. Efficient organization and preparation for one of Europe’s largest earth-moving projects is ensuring smooth progress, and an architectural fair has offered a diverse range of architectural styles. The fact that “times, they are a-changing” has always been evident between the Rhine, Lippe and Ruhr rivers, as industrial change has molded life in the region for centuries. This dynamic is particularly apparent in the south of Dortmund, where one of Europe‘s largest urban development projects is changing the face of the city. For 150 years and over many generations, the character of the district of Hörde was determined by heavy industry: In the mid-19th century, production and processing of steel began on the so-called Phoenix site. It was the decline of Germany‘s coal and steel industries in the 1970s that brought this to an end. The plant was closed in 2001 followed by the dismantling of equipment and a partial sale to China. Dortmund seizes the opportunity The City of Dortmund seized the opportunity by purchasing the site shortly before the turn of the century: The 100hectare disused site was bought back for the people. This gave new impetus to the idea of living and working in one place, a visionary concept that seemed to have been long lost. The inspiration generated by this idea can be seen in nearly every corner of the district. An artificial 25-hectare lake with a depth of up to four meters and several islands is being created on the site of the former Hermannshütte steel plant. The lake will be surrounded by 42 hectares of residential and commercial properties, including some 900 homes for approximately 2,500 people. This will be supplemented by extensive parklands totaling about 11 hectares with the renatured Emscher River and Hörder Stream taking up about 13 hectares. The new living and working area will one day become part of the Emscher Landscape Park, and is an example of the ‘green’ structural change taking place in the region formerly dominated by heavy industry. Coordination of the planning and approval processes Clearly the preparation and execution of such a fundamental change of use for an entire district is a mammoth task. Initially, it posed substantial problems for those responsible, namely the PHOENIX See Entwicklungsgesellschaft mbH and the Emscher River Association. A 25-hectare lake and extensive parklands will shape the future of the former PHOENIX West coal mine site This is where the Drees & Sommer infrastructure specialists came into the picture in November 2005. The expert team helped the principals to achieve their goals and to master the associated organizational challenges. Since then – as project controller – the company has been coordinating the activities of two principals, numerous authorities, funding institutions, planners, consultants, and numerous contractors, including about 40 engineering firms and consultants. The construction-related tasks were almost as challenging. Following dismantling, demolition, remediation and safety work, the experts managed all foundation and hydraulic engineering tasks. At the same time, civil engineering works such as a weir system and bridges, and building construction projects – including a phosphate elimination plant to minimize the nutrient content of the waters – had to be undertaken. Another task was the construction of the complete infrastructure with roads, paths, squares and parklands. Site logistics for a lake larger than Hamburg’s Inner Alster Earthworks for the lake – which will one day be larger than Hamburg’s Inner Alster – resulted in huge quantities of excavated material: Over a million cubic meters of soil had to be transported to the correct location with over 300,000 dump-truck trips. To do this, the Drees & Sommer expert team established the organizational parameters from the very beginning and undertook “Drees & Sommer provided us with outstanding support.” Ursula Klischan, Managing Director of PHOENIX See Entwicklungsgesellschaft mbH at EXPO Real 2010 16 17
REDEVELOPMENT OF A DISUSED INDUSTRIAL SITE comprehensive site logistics throughout the entire construction period. At peak periods, over 150 major pieces of equipment – such as excavators, bulldozers, rollers and all types of transport vehicles – were in operation on the extensive site. Timely completion of the demanding schedule is an important condition for the award of subsidies. Professional cost and subsidy management is required, as the project is being subsidized by the state of North Rhine-Westfalia, the German Federal Government and the EU. To guarantee the efficient application of funds, Drees & Sommer is also undertaking comprehensive supplementary claim management. Marketing and architectural fair The lake has been filling with water since autumn 2010, gradually giving an idea of the future shape of the huge site. With the support of established Drees & Sommer experts for development management, marketing of the new home sites is progressing apace in parallel with the visible progress of construction on the site. 18 In November 2009, Drees & Sommer organized an innovative architectural fair called “Building on Lake Phoenix” which received a great deal of attention from both the public and experts. Some 50 architects – mostly from the region – presented designs for homes to be built on sites around the lake. Upmarket detached and duplex homes with striking architecture are to be built on a good 200 sites on the site’s southern slope. Nearly all homesites on this southern slope have already been sold, with construction to begin from mid 2011. The remaining 140 sites on the southern shore will be marketed at a further architectural fair in 2011. The specialists hosted a creative workshop with architects and communications agencies for the planned commercial and service buildings on the southern and western shores of the lake. The event was an immediate success, with large areas sold to investors. So gradually, life is returning to the former industrial wasteland. Designs for commercial and service buildings on the lake were presented at a creative workshop at the same time as rapidly proceeding construction work Clients – PHOENIX See Entwicklungsgesellschaft mbH, Dortmund – Emscher River Association, Essen Key project data – Lake PHOENIX total area: 100 ha – Residential component: 29 ha – Commercial component: 13 ha – Emscher River/Hörder Stream: 13 ha – Public parkland: 11 ha – Public roads, paths and areas: 12 ha – Communal facilities etc.: 5 ha – Cost: Approx. €240 million net Schedule – Remediation: 2005 – 2009 – Dismantling: 2008 – Excavation of lake: 2007 – 2009 – Earthworks: 2007 – 2011 – Civil engineering works for lake & Emscher River: 2008 – 2010 – Bridges, weir system, port: 2009 – 2010 – Flooding of lake: 2010 – 2011 – Construction management planning: 2006 – 2011 – Urban development on Lake PHOENIX site: From 2009 – Integration into existing, partially adapted external infrastructure: From 2010 Drees & Sommer services – Project control – Project management – Management of creative workshop for commercial buildings – Management of architectural competition for residential buildings – Development management with marketing support Value-add achieved for client – “Temporary construction department” to ease burden on clients – Cost transparency – Successful subsidy management – Numerous ideas as a result of architectural fair – Public acceptance – Marketing support 19
