Java-Bali towers to stand 295 m tall

Merz and McLellan, consulting engineers, are designing two “record-breaking” towers to bring power from Java to Bali. The structures will be 295 m tall, nearly as tall as the Eiffel Tower, and will weigh 920 metric tons each. They will take power to Bali over a 2.5-km-wide shipping lane and are thought to be the largest free-standing transmission line towers in the world.

Current designs show foundations of eight 1-m-diameter concrete piles for each leg, extending 25 to 30 m into the ground. In addition to the strain of the cables, the towers, which will be constructed by ABB of Germany, must be able to withstand heavy seismic activity and powerful winds of tropical storms.
