On the Amsterdam Oosterdokseiland, approximately 200.000m2 of new construction has been realised. The project includes a hotel with a congress centre, housing, shops and horeca, office spaces, a library, a conservatory and leisure space. Beneath the buildings, a two-storied 50.000m2 basement is partly designated for one of the aforementioned functions
and partly serves as parking space for cars and bicycles. In total, the project is divided in six plots that have been developed autonomously (to some extent). Structure consultancy for the entire project has been entrusted to general partnership Aronsohn – Arcadis Oosterdokseiland.

Structural design

Within the general partnership, Aronsohn has provided structure advice for the following project components:

– Plot 5, which contains the new construction of the Conservatorium van Amsterdam (approximately 14.500m2), underground leisure facilities (approximately 5.000m2), and office space (approximately 21.000m2), designed by architects De Architecten Cie and Zwarts & Jansma.

– Plot 6, containing an office building that utilizes the existing construction of the Post Expeditie Knooppunt, a number of houses and a blob-shaped horeca facility. In total, plot 6 encompasses 46.400m2. Architects are (respectively) Erick van Egeraat Associated Architects, Baumschlager-Eberle, and Future Systems.

– The two-story basement that lies underneath all six plots.

The project involves a high level of complexity. The conservatory houses a great number of spaces designated for education and presentation, including grand and small music halls, studios et cetera. Such facilities require accurate and meticulous acoustic design. Additionally, the office buildings on both plot 5 and 6 are partly cantilevered over an access road on the north side of the island, where the Oosterdokseiland is bordered by Amsterdam Central Station railroads.

To achieve this, table structures have been designed that are highly interesting from a structure engineering and architectural point of view. Finally, the phased building process, underground foundation remains, and nearby railroads demanded special structure solutions.
