In the realm of giants

Whether in Frankfurt, the USA, Australia or Asia: HOCHTIEF erects buildings that seem to shoot into the sky. A job for people with a head for heights.

Chien-Jou Chen—Skyscraper in person

Chien-Jou Chen, a native of Taiwan and a Project Manager at our US subsidiary Turner. His mission: build the world's tallest skyscrapers. After the Taipei 101 (508 meters) and the world record-breaking Burj Khalifa (828 meters), he and his team are currently completing the world's second tallest building in Malaysia's capital Kuala Lumpur: Merdeka 118.

Six hundred and seventy-eight point nine meters high. 6-7-8, 9! The giant is to become the greenest skyscraper in the world. "Constructing such buildings is like developing a Formula 1 car," says Chen.

Key figures

Selected features

Special concrete

We have developed particularly sustainable concrete for Merdeka 118. It can now be used everywhere.

Future of skyscrapers

Particularly in Southeast Asia Chen sees a large market for buildings up to 400 meters high.

Water cooling

Every minute, 40,000 liters are pumped through the building. Water cooling is one of many environmental measures.


Of course, building such giants is stressful. Chen's recipe for it: meditation.


A high-rise like this is not a one-man show, but a team effort. And Chen reveals how he sets priorities.

Panorama elevator
