This publication deals with the dialogue, the increasingly important direct exchange of information, between architects and structural engineers as part of an expert and creative exchange. As a result of his diverse career experience, which includes experimental design, construction and lecturing activities, Werner Sobek is one of the leading protagonists in his field on the world stage. At his Institute for Lightweight Structures and Conceptual Design (ILEK) at the University of Stuttgart, he leads an interdisciplinary team that explores the limits of what is possible in terms of construction and expands them. In addition to his university work, Werner Sobek - in partnership with notable architects and therefore often invisible to the general public - has also come to attention of often spectaculr concepts as well as in his activties as an architect working on his own projects and highly regarded constructions. Werner Sobek´s group of companies represents world-class engineering, design ans sustainability. It has branch offices in Stuttgart, Dubai, Frankfurt, Cairo, Moscow and New York. The work of the company, which was founded in 1992, can be characterised by it highclass design in the basis of exceptional enineering and intelligent concepts to minimise energy and material use. Werner Sobek works with the pioneering architects of our time such as Norman Foster, Meinhard von Gerkan/Volkwin Marg, Zaha Hadid, Hans Hollein, Christoph Ingenhoven, Helmut Jahn, Kisho Kurokawa and Dominique Perrault an teh construction of high-rise buildings, airports, office buildings and museums.
