structural system developed specifically for it. In terms of structures and materials, the science centre is a kind of a conglomeration. It contains concrete, steel and wood constructs. The building has mostly been built from pre-built components, but it also contains some parts built in place. The base floor of the exhibition spaces contains a semi-heated service space for the building services engineering elements needed by the exhibition. The outlets and connection possibilities have been systematically placed in a 2.4 metre grid into the entire building. This allows for enough flexibility to host exhibitions. The Finnish Science Centre Foundation and funding Heureka is run by the Finnish Science Centre Foundation, whose original members include the University of Helsinki, the Helsinki University of Technology (nowadays Aalto University), the Federation of Finnish Learned Societies, and the Confederation of Industries (nowadays Confederation of Finnish Industries, EK), the City of Vantaa, the Ministry of Education (nowadays Ministry of Education and Culture), the Ministry of Trade and Industry (nowadays Ministry of Employment and the Economy), the Ministry of Finance, the Central Organisation of Finnish Trade Unions (SAK), and the Trade Union of Education in Finland (OAJ). Heureka's funding is provided through subsidies from the City of Vantaa and the Ministry of Education and Culture, as well as through its own operational revenue: admission and rental fees, fundraising and exhibition export. Heureka's overall funding is approximately ten million euro, of which the revenue from own operations is about one half. The share of the funding provided by the City of Vantaa and the Ministry of Education and Culture amounts to the other half. The public support is notably less than for many other cultural institutions. Part of the funding also comes through corporate co-operation. The temporary exhibitions are often sponsored by main partners and other partners. Heureka also has two companies owned entirely by the Foundation, namely the Science Shop Magneetti Oy, which runs the Heureka Shop at Heureka and at the Kamppi Center in central Helsinki, and Heureka Overseas Productions Oy Ltd, which manages the export activities of Heureka. Other Professor Per-Edvin Persson served as the president of Heureka since 1991, and after he retired he was succeeded by Anneli Pauli in 2013. Tapio Koivu started as the president of Heureka in August 2014. Mikko Myllykoski was chosen as the president of Heureka in September 2020, having previously served as the experience director of Heureka
