Dubai to open world highest tower

DUBAI (AP) — Dubai is set to open the world’s tallest building amid tight security on Monday, celebrating the tower as a bold feat on the world stage despite the city state’s shaky financial footing.

But the final height of the Burj Dubai — Arabic for Dubai Tower — remained a closely guarded secret on the eve of its opening. At more than 2,625 feet (800 meters), it long ago vanquished its nearest rival, the Taipei 101 in Taiwan.

The Burj’s record-seeking developers didn’t stop there.

The building boasts the most stories and highest occupied floor of any building in the world, and ranks as the world’s tallest structure, beating out a television mast in North Dakota. Its observation deck — on floor 124 — also sets a record.

“We weren’t sure how high we could go,” said Bill Baker, the building’s structural engineer, who is in Dubai for the inauguration. “It was kind of an exploration. … A learning experience”

Baker, of Chicago-based architecture and engineering firm Skidmore, Owings & Merrill, said early designs for the Burj had it edging out the world’s previous record-holder, the Taipei 101, by about 33 feet (10 meters). The Taiwan tower rises 1,667 feet (508 meters).

The Burj’s developer, Emaar Properties, kept pushing the design higher even after construction began, eventually putting it about 984 feet (300 meters) taller than its nearest competitor, Baker said. He is keeping quiet about the exact height.

Dubai’s ruler will open the tapering metal-and-glass spire with a fireworks display Monday evening.
