Work to create an Indonesian skyscraper twice the height of Auckland's Sky Tower has been won by Auckland consultancy Beca.
A spokesperson said the business had won the contract to provide the mechanical and electrical engineering design for Jakarta's Signature Tower, the tallest building planned in the Southern Hemisphere.
It will be the fifth-tallest building in the world, standing 638m, with a 10-level retail podium, three office zones, a six-star hotel and a viewing observatory at the 111th level.
"Challenges include engineering a complex network of over 100 lifts, two of which shuttle vertically over half a kilometre from the ground floor to the observatory," said the Beca spokesperson.
Construction will start in the middle of the year and will not finish until 2017.
