Description

Start of the realization phase of the project began in September 2019 with the design and construction of a large-scale mock-up. The Installation of the project “L’Arc de Triomphe, Wrapped” was scheduled for September 2020. Based on this mock-up, Christo decided the colour of the fabric (type of blue) and the number and diameter of the red ropes.
Büro für leichtbau (bfl) developed the tensioning system for the fabric in the vaults and designed the configuration of the steel pipes for the tensioning of the vault and façade panels at the front edge of the vaults. A vault tensioning test was made in Lübeck at “geo die Luftwerker” to check that the fabric is really horizontal tensioned for the 23m free span.
Based on the hullgeometry of Christos drawings, the position of linear steel pipes is defined. Sbp developed and analysed the support structure for these pipes and their anchoring on the Arc as well as the 4 steel cages on the main façades. Then bfl analysed the stress in the fabric, the red ropes and the textile shackles for the fixing at the supporting structure behind the fabric based on the wind tunnel test report of Wacker Ingenieure. The fabric details were tested in the Lab of DEKRA, Stuttgart. Special brackets and clamps were designed and produced for the testing.
Bfl developed the folding and cutting patterns for the fabric as well as the fixings of the fabric on the roof and the façade. They used the same anchoring system on the base as on Christo’s “Wrapped Reichstag” project adapted to the special situation with the stone bench. They managed the flow of material, which were needed for the manufacturing.
Bfl made all the tests for the elongation parameters of the fabric inhouse and for the red ropes in a factory of Arnegger GmbH. They clarified with Christo the final position of the vertical and tensioned horizontal red ropes based on the geometry of the cages. A 1:3 corner mock-up was built in Berlin at Gerüstbau Tisch GmbH to check the details at the corner with the type of patterning based on a 1:20 mock-up built in the bfl office in Radolfzell.
At the end of April 2020 Christo decided cause of the Covid situation to shift the installation to September 2021. In May 2021 Christo passed away. Bfl supervised the folding and rolling process and preparing the fabric for the installation at “geo die Luftwerker” near Lübeck. An installation test with unrolling of the fabric were made with the Installation company JADE in the industrial climber trainings areal in Dunkerque. Bfl introduced JADE in the installation process based on the experience of the “Wrapped Reichstag” project.
