ADVANCING THE INDUSTRY
Langan proudly sponsored and attended the CTBUH 2023 International Conference in Singapore and Kuala Lumpur last month, 15–21 October. Seth Martin, Associate, presented some of the insights gained and lessons learned while working on various projects in Malaysia for nearly 15 years in his presentation, entitled “A Decade of Foundations for Supertall and Megatall Towers in Malaysia.”

CTBUH Designated Expert Ramin Golesorkhi also represented Langan at the conference, strengthening relationships with leaders focused on developing sustainable, innovative, urban spaces around the world.

PROJECT SPOTLIGHT: KUALA LUMPUR CITY CENTRE
Langan is playing a crucial role in the 100-acre Kuala Lumpur City Centre (KLCC) in Malaysia, anchored by the Petronas Twin Towers. As the geotechnical engineer for many of the towers surrounding KLCC Park, Langan has developed innovative and practical solutions to support supertall and megatall buildings in some of the world’s most complex geological settings. The firm has worked on KLCC towers with pile foundations up to 125 meters deep, solidifying them as some of the deepest building foundations in the world.

Construction of this “city within a city” is ongoing, and Langan continues to work with the project design, construction teams, and local engineering firms to bring this dynamic, multipurpose concept to fruition.
