Some of the piles on the new high-rise development at Kuala Lumpur City Center, which Bauer is working on for Arena Medu, will extend to 150m below ground level.
The development will have a four-level basement car park with a five storey shopping centre and office tower. Bauer is delivering diaphragm wall construction and piling work for the scheme.
Bauer will construct 225 piles for the project and 137 of these will have a 2.5m diameter and extend to depths of between 90m and 150m.
“These are currently, to my knowledge, the deepest piles ever made in Malaysia,” said Bauer Malaysia general manager Egon Stahl.
Bauer is undertaking ground investigation work at each pile location before starting work in order to determine the depth to competent bedrock and the pile toe level.
Bauer is using its largest rotary drilling rig – a BG 72 – with five four-fold Kelly bars to reach 150m depth.
“The project is a record in three aspects: Bauer is doing drilling work for the deepest piles to date in Malaysia, with what is currently Bauer’s largest drilling rig and the world’s longest kelly bar. It’s truly unique project,” said Stahl.
In addition to the deep tower piles, 88 of 2m diameter bored piles are being constructed to depths of 75m for the shopping complex area. The diaphragm wall retaining wall for the basement will have a thickness of 1m and extend to a depth of 38m.
