16 months after the groundbreaking ceremony Topping-out ceremony for the new nuclear chemistry building at the Johannes Gutenberg University Mainz

Only about 16 months after the symbolic ground-breaking ceremony, the shell of the new laboratory and office building for nuclear chemistry with the research reactor TRIGA Mainz at the Johannes Gutenberg University Mainz (JGU) has been completed. At the topping-out ceremony on 09.11.2021, Science Minister Clemens Hoch, State Secretary of Finance Dr. Stephan Weinberg, JGU Chancellor Dr Waltraud Kreutz-Gers and the Managing Director of the Landesbetrieb LBB, Holger Basten, acknowledged the importance of the new building project, which is being managed by the LBB Mainz branch.

In terms of design and construction, DGI Bauwerk work as general planner under the direction of architect Constanze Tibes: “Building for science means form follows function. The new replacement building for the original laboratory and office building for nuclear chemistry continues the existing ensemble in terms of function and design. But building for science also means building for the future and the people who work in it. That is why transparency, brightness and a pleasant feeling of space are particularly important. For example, the foyer receives daylight from both sides and the new underground connecting passage to TRIGA Mainz has generous glazing in the roof ceiling.”

In terms of urban planning, the task was to organise a demanding room programme as well as supplementary rooms required by radiation protection law on the very limited open space of the Kernchemie site. The separation of the areas relevant to radiation protection (monitoring area) from the other rooms runs through all levels from the basement to the technical floor. The result is a compact building with edges measuring around 50 by 30 metres, which makes optimal use of the building site on Jakob-Welder-Weg. The new building will take over the street line and the staggered heights of the neighbouring laboratory building. This creates a coherent ensemble.
