A scandal involving defective concrete columns and unauthorised repairs at a railway station under construction has sparked debate, with some experts attributing the structural gaps to unfinished work and others condemning them as unacceptable errors that raise fears of a wider decline in Hong Kong’s building sector.
Authorities have identified about 30 defective columns at the MTR Corporation’s Tung Chung West station but say temporary supports mean there is no structural danger.
The South China Morning Post explains what is known so far, who oversees the work and what the incident could mean for safety and the extension’s targeted completion in 2029.
1. What is the project?
Tung Chung West is one of two new stations being built as part of a HK$24.2 billion Tung Chung line extension, on which construction began in May 2023 with completion targeted in 2029.
