On June 26, 2006 the 10 members of the Quality Chamber were officially presented. Antwerp local government architect Kristaan Borret and ir. Dirk Brusselaers, representative of the Flemish Administration, former deputy chef de cabinet to Minister Van Mechelen, both joined the chamber. Prof ir. Cecil Balmond, an authority in the field of structural design, immediately put ir. Joop Paul forward to replace him, a director of Arup Nederland, who had, for instance, been involved in the construction of the Nesciobrug in Amsterdam. Prof ir. Jörg Schlaich, an eminent designer of bridges, resigned after the quality chamber's first meeting. 'It makes no sense to take part in a competition that isn’t judged by a jury of excellent engineers specialising in bridges, who are knowledgeable about designing bridges.' (extract from his letter of resignation, cited in weekly magazine Humo).
