Megastructures

The Shanghai Tower (Chinese: 上海中心大厦; pinyin: Shànghǎi Zhōngxīn Dàshà; Shanghainese: Zånhe Tsonshin Dasa; literally: "Shanghai Centre Tower") is a 632-metre (2,073 ft), 128-story megatall skyscraper in Lujiazui, Pudong, Shanghai.[9]. It also has the world's highest observation deck within a building or structure (Level 121, 561.25 m),[10] and the world's fastest elevators at a top speed of nearly 46 miles per hour (74km/h).[11][12] It is the world's second-tallest building by height to architectural top (behind Dubai's Burj Khalifa, 828 m). Designed by international design firm Gensler and owned by the Shanghai city government,[2] it is the tallest of the world's first triple-adjacent super-tall buildings in Pudong, the other two being the Jin Mao Tower and the Shanghai World Financial Centre. Its tiered construction, designed for high energy efficiency, provides nine separate zones divided between office, retail and leisure use.[

he World or The World Islands (Arabic: جزر العالم; Juzur al-Ālam) is an artificial archipelago of various small islands constructed in the rough shape of a world map, located in the waters of the Persian Gulf, 4.0 kilometres (2.5 mi) off the coast of Dubai, United Arab Emirates.[1] The World islands are composed mainly of sand dredged from Dubai's shallow coastal waters, and are one of several artificial island developments in Dubai.[1] The World's developer is Nakheel Properties, and the project was originally conceived by Sheikh Mohammed bin Rashid Al Maktoum, the ruler of Dubai. Construction of the 300 islands began in 2003, only to halt due to the 2008 financial crisis.[2] Though 60 percent of the islands had been sold off to private contractors back in 2008, development on most of these islands has failed to initiate.[3] As of July 2012, the Lebanon Island was developed and was the only island that had so far been developed commercially, being used for private corporate events and public parties. As of late 2013, only two of the islands had been developed. In January 2014, Kleindienst Group announced the launch of "The Heart of Europe" project;[4] by February 2014, one of Kleindienst Group's brands - JK Properties - announced in their monthly newsletter that the project was "well underway".[5] The first of these series of islands will be Europe, Sweden and Germany with development led by Kleindienst Group.
