Louvre Abu Dhabi’s dome lifted into final position

Abu Dhabi's Tourism Development and Investment Company yesterday announced that the dome of Louvre Abu Dhabi has been successfully lifted and placed into its final position – firmly sitting on top of the museum's four main permanent piers.
The lift process included raising the dome off the temporary towers and then lowering it 38 centimetres down to permanent piers. The final touchdown took place in the presence of Ali Majed Al Mansoori, TDIC's Chairman of the Board, along with some board members, TDIC senior management and senior management of the main contractors.
Preparations in the run up to the lifting of the dome included extensive testing of the bearings that will hold the dome throughout its lifespan. The bearings underwent months of testing in California, USA, where it was proven they can support the final weight of the dome. The lift was possible with the utilisation of 32 hydraulic jacks that can hold up to 10,000 tonnes in weight and which were operated simultaneously and remotely. The jacks were especially manufactured for the project, underscoring the complexity and uniqueness of museum's design and construction. The dome of the museum, which was constructed over the span of 10 months, was originally built on top of 120 temporary towers as a way to support its weight during the construction process. Its lift is the first of its kind in the world of construction for a permanent structure of this scale and size. The dome weighs 7,000 tonnes and is 180 metres wide.
Ali Majed Al Mansoori, TDIC's Chairman of the Board, said, "We are proud of the successes and milestones being achieved on the site of Louvre Abu Dhabi. We applaud the dedication and hard work of the teams working together to achieve this unprecedented work that reflects the best of the worlds of architecture, engineering and construction today. This also attests to the continued drive of the United Arab Emirates to be one of the few countries in the world where unique projects such as this one, which require innovation and technology, can happen. We can only look forward with high anticipation to what Louvre Abu Dhabi is going to bring to the world of art and culture regionally and worldwide." Johann Sischka, a board member of Waagner-Biro Stahlbau AG, a leading Austrian steel engineering organisation that was appointed to construct the dome, said, "The construction and sophistication of the Louvre Abu Dhabi's dome is among the more unique projects we have undertaken. It is remarkable in its design and size, and given that it must be placed in precise spots on its four piers, there was no room for error. One would not believe the amount of detail that goes down to achieving the results we have realised today." Construction is progressing on-site of Louvre Abu Dhabi. To date, the concrete work has been almost completed. A total of 34,000 tonnes of reinforcement steel has been used and over 21 million man-hours completed on-site. The construction of the permanent gallery structures have been completed, along with the concrete work for the museum's basement levels and the security screening facility, a highly secure seven-metre deep basement through which authorised vehicles will transport all the artwork of the museum. Work is also progressing on the 1.2 kilometre Saadiyat Tunnel which will be the main entryway for the artworks as they are transported to their destination.
Designed by Pritzker-prize winning architect Jean Nouvel, Louvre Abu Dhabi will encompass 9,200 square metres of art galleries. The 6,681-square-metre Permanent Galleries will house the museum's permanent collection, taking visitors through a universal journey from the most ancient to contemporary art works from different civilisations. There will be a dedicated space of 2,364 square metres for temporary exhibitions.
Louvre Abu Dhabi, when completed, will be one of the premier cultural institutions located in the heart of the Saadiyat Cultural District. These feature the Zayed National Museum and Guggenheim Abu Dhabi, both also designed by world-renowned Pritzker-prize winning architects.
