For the first time, the work of the two engineers Jörg Schlaich and Rudolf Bergermann is being exhibited in Madrid, at the Instituto de Ciencias de la Construcción Eduardo Torroja. The exhibition is called “estructuras ligeras”. To accompany the exhibition is a book of retrospective, printed in Spanish. The layout reflects the new look of the Stuttgart office of schlaich bergermann partner: light, precise structures, black and white surfaces in contrast to the colour of the project pictures.
