Expansion Plan, to prepare zoning plans that would predict overall future development in the city. He relied upon the more rational methods being promoted by CIAM at that time which sought to use statistical information for designing zone uses rather than designing them in any detail. At a special congress meeting in Berlin later in 1931 van Eesteren presented his findings to his colleagues. He presented three drawings of Amsterdam. The first at a scale of 1:10000 showed land use and density, the second showed transportation networks and the third, at 1:50000 showed the regional setting of the city. He also presented supporting information on the four functions of dwelling, work, recreation and transport. Based upon his presentation it was decided that the separate national groups within CIAM would prepare similar presentation boards for the Moscow meeting. A standard set of notation was agreed. In 1932 Le Corbusier's Palace of the Soviets competition entry failed to gain acceptance from the jury and, due to the political conditions in Russia, CIAM's agenda became increasingly ignored. A new venue for the fourth CIAM conference was required. CIAM 4 The fourth CIAM conference took place on board the S.S. Patris, an ocean-going liner journeying from Marseilles to Athens in July 1933. The national groups reported to the conference with the findings from their city studies, presenting in each case the agreed three boards showing a total of 33 cities. In addition, Le Corbusier and the group who had met earlier in Zürich hosted a meeting to state the core goals of the Functional City. On arrival in Athens on 3 August an exhibition of the Functional City boards was held at the National Technical University of Athens and inaugurated by Greece's prime minister. The boards were separated into seven categories: metropolises, cities of administration, ports, industrial cities, pleasure cities and cities of diverse function. The delegates remained in Athens for a number of days, some visited local classical sites and others visited nearby islands. On 10 August they embarked on the return journey to Marseilles. During meetings on the return journey delegates found it impossible to agree on resolutions for the Functional City. Van Eesteren's original Amsterdam plan had, with greater resources, a basis formed by scientific data. The plans presented by the national groups did not have this and, despite Giedion's insistence, delegates were reluctant to agree on guidelines. Eventually, two groups
