Olympiastadion (Munich) owned by Munich
Election
To make room for the arena, the terminal building of the old airport had to be blown up. On 9 June 1969 work began on the stadium, the multi-purpose Olympic arena and swimming pool. However, it was only on 14 July 1969 with the laying of the cornerstone in a symbolic ceremony that the construction officially begun. In addition to the three buildings emerging on the Oberwiesenfeld, the Werner von Linde Hall, a volleyball hall, the Olympic Radstadion, the Olympic Village and various other buildings such as stations for U-Bahn and S-Bahn were built. During the time of the construction there was a spirit of optimism in Munich. The inner city received a pedestrian zone between Marienplatz and the Stachus and the metro was implemented. on the Oberwiesenfeld alone, there were 60 construction sites. From a total of 1.35 billion German marks, 137 million were used in the construction of the Olympic Stadium and another 170.6 million in the tent roof. About 5,000 construction workers worked at the construction site for more than one million hours. Contrary to the custom of German construction, the Olympic Stadium was built largely without prefabricated parts.
According to Behnisch, the stadium was to be a "democratic sports venue" according to the ideas of the Mayor of Munich Hans-Jochen Vogel and the specifications of the Federal Chancellor Willy Brandt, creating a contrast to the 1936 Summer Olympics in Berlin during the period of National Socialism, the hitherto single summer Olympics in Germany. Since the time of National Socialism, Munich had the reputation of being the "capital of the Nazi movement". The Olympics were intended to help improve Munich's reputation. The foundation's deed stated that the planned games should "bear witness to the spirit of our people in the last third of the 20th century".Behnisch wanted Frei Otto as a partner architect, whose tent roof construction at the EXPO 1967 in Montreal was a model for the stadium tent roof. Otto had already been involved in numerous construction projects with suspended and membrane structures and became the development consultant for the Olympiastadion tent roof construction. In addition to Behnisch and Otto, an architect team was also formed to realize the roof construction, including Fritz Leonhardt and Wolf Andrä. The planning management was done by Fritz Auer. Otto developed parts of the roof by means of the trial-and-error principle by making larger models of the roof construction, while Andrä and Leonhardt developed the roof with a CAD program elsewhere. Under the direction of civil engineer Jörg Schlaich, the roof over the stadium was completed on 21 April 1972. But the planned flat tent roof to cover an additional 15,000 seats in the eastern stands of the stadium, was never built; only the main foundations to hold the second roof were built, and they are still visible; one in each of the curves: behind, respectively under the existing roof. (In total some 60,000 seats would have been covered by the two separate tent roofs.)
Already in the summer of 1970 the shell of the buildings was finished and on 23 July 1970 the topping-out ceremony was celebrated. The plans for the stadium had forgotten to allocate cabins for football teams in the stadium interior. For this reason, from 24 May 1972 to the official opening of the stadium on 26 May 1972, two medical rooms were provisionally converted into changing rooms. There was enough room to set up a room for paramedics and referees as well. Later, the cabins were further equipped and remained in place. At the turn of the year 1971/1972 the main works were finished and at the end of June 1972 the finished buildings were handed over to the organizing committee. The planning, construction and financing of the buildings were controlled by the 1967 founded Olympia-Baugesellschaft mbH Munich, which was founded by the Federal Republic of Germany, the Free State of Bavaria and the City of Munich. The stadium is property of the Olympiapark München GmbH, a society wholly owned by the City of Munich's Referat für Arbeit und Wirtschaft.
