Burj Dubai (1), a tower under construction in the United Arab Emirates' trade hub (2), became the tallest building in the world on Saturday, measuring 512.1 metres, its developer said.

"Burj Dubai is now taller than Taipei 101 in Taiwan, which at 508 metres has held the tallest-building-in-the-world title since it opened in 2004," Emaar Properties, which is developing the Dubai tower, said in a statement.

"Burj Dubai has now reached 141 storeys, more storeys than any other building in the world."

The developer wants the tower, set to be completed next year, to be the world's tallest building according to all four criteria listed by the Chicago-based Council on Tall Buildings and Urban Habitat, which measures buildings to the structural top, the highest occupied floor, the top of the roof and the tip of the spire or flagpole.

Emaar did not say how tall the finished building will be.

Once completed, Burj Dubai will have consumed 330,000 cubic metres of concrete (3), 39,000 tonnes of steel and 142,000 square metres of glass, Emaar said. It will have 56 lifts travelling at 1.75 to 10 metres per second.

The tower will be the centrepiece of a $20 billion development that will include residential, commercial and retail property.

Dubai, the Gulf Arab trade and tourism hub, has embarked on a series of mega-projects (4) in recent years, developing three palm-shaped (5) islands off its coast and a cluster of (6) man-made islands shaped like a map of the world.

位于阿聯(lián)酋貿(mào)易中心的在建的“迪拜塔”的開(kāi)發(fā)商在星期六稱(chēng)：高512.1米的迪拜塔是世界上最高的建筑。

迪拜塔的開(kāi)發(fā)商埃瑪爾地產(chǎn)酒店集團(tuán)表示說(shuō)：“迪拜塔比臺(tái)灣的臺(tái)北101高，高508米的臺(tái)北101于2004年投入使用，一直以來(lái)都被譽(yù)為是世界最高的建筑。”

“迪拜塔有141層樓，比起世界上的任何其他建筑，迪拜塔的樓層是最多的。”

開(kāi)發(fā)商計(jì)劃在明年建成這座世界最高的迪拜塔，并參照芝加哥高樓與都市住宅委員會(huì)所列出的所有四項(xiàng)標(biāo)準(zhǔn)。這些標(biāo)準(zhǔn)包括測(cè)量建筑高度、被使用的最高樓層、建筑物頂端和旗桿頂部。

艾瑪爾地產(chǎn)酒店體團(tuán)并沒(méi)有表明完成之后的建筑高度到底是多少。

據(jù)艾瑪爾地產(chǎn)酒店體團(tuán)稱(chēng)，迪拜塔的完工將消耗33萬(wàn)立方米的混凝土，3.9萬(wàn)噸鋼筋和14.2平方米的玻璃。另外，還有56部電梯以每秒1.75到10米的速度運(yùn)行。

迪拜塔是一座中心建筑，合周?chē)囊恍┳≌⑸虡I(yè)和零售業(yè)的建筑，總價(jià)值20億美元。

作為阿拉伯灣貿(mào)易和旅游的中心，近年來(lái)，迪拜已經(jīng)見(jiàn)證了一系列重要工程的落成完工，在其海岸上修建了三座棕櫚形狀的小島，和一群人工小島，形似世界地圖。
