In mid-1999, the Köln-Messe/Deutz ICE terminal was submitted to an international architectural competition and received 57 proposals. Both urban and transport issues were taken into account. Eight finalists were selected. The project affected 22 hectares of land and 150,000 square metres of floor area. The objectives included the extension and adaptation of the two low level platforms for ICE traffic and the duplication of the access track. An expansion to four ICE platforms was considered. The plan also included an 800-metre-long, covered moving walkway that would have connected the station to Cologne Hauptbahnhof. This competition was judged by DB, the city of Cologne and the Cologne Trade Fair and was concluded in 2000. The development scheme was submitted for planning approval in October 2000. The estimated cost of the overall concept of 140 million Marks was funded by DB, the city of Cologne and the Trade Fair. A glass roof with a length of 120 metres, which should span the entire station was calculated to cost an additional DM 40 million.
