KLCC L&M Tower - Foundation Piles XXLConstruction of the Actually Deepest Foundation Piles Ever Done by the Kelly Method in Kuala Lumpur / Malaysia-Video

Video Transcription

Video Summary

Vijay, a Malaysian engineer, presented the construction of deep foundations for a planned 700-plus-meter tower in Kuala Lumpur. The site’s challenging geology includes dense weathered sandstone and shale over cavernous limestone. The project required 2.5-meter-diameter piles, some extending beyond 120 meters, and prompted the team to modify drilling equipment to reach depths of up to 150 meters.<br /><br />Key challenges included maintaining pile verticality, stabilizing deep boreholes, installing heavy reinforcement cages and king posts, and completing each pile within a 36-hour limit. The team used long drilling tools, sonic caliper checks, polymer drilling fluid, staged sediment removal, and carefully planned cage and tremie-pipe installation. Concrete temperature, workability, and delivery rates were also tightly controlled.<br /><br />Despite the scale and complexity, the team achieved the required tolerances and completed approximately 500,000 work hours with no accidents or lost-time injuries.
