US firm Wilmer Cutler & Pickering has been appointed by the Berlin Airport Project Company to structure the privatisation of three Berlin airports, and subsequent closure of two of them. The present shareholders, the German government and the states of Brandenburg and Berlin, plan to use private finance for the intended expansion in 2002 of Schonefeld Airport, which it is estimated, will cost in the region of $4.9bn. Schonefeld will be the only airport serving the city of Berlin after the closure of Tegel and Tempelhof airports. Wilmer Cutler & Pickering will work alongside German firm Bruckhaus Westrick Stegermann and investment bank Barclays de Zoete on the deal.
