All the cranes have come down from Burj Dubai, according to a source close to the project. "The last crane was down by the third week of October," the source told Emirates Business.

In September, an Emaar spokesperson had sent this newspaper a statement that the last of the cranes atop the Burj Dubai would be taken down in a few weeks. The cranes were originally supposed to come down by end of August.

The building, when completed, will meet all four criteria listed by the Council on Tall Buildings and Urban Habitat (CTBUH) – the body that classifies the world's tallest structures.

CTBUH measures the height of buildings to the structural top, the highest occupied floor, the top of the roof and the tip of the spire, pinnacle, antenna, mast or flag pole.

Emaar said last month that the Burj Dubai tower has accomplished a world record for the highest installation of an aluminium and glass façade. Keeping the tower façade clean will be the next engineering challenge, it said. "To guarantee that every corner of Burj Dubai sparkles, 18 window-washing units are built into the tower," said the statement.
