Experts point out that high-strength concrete is required to correct defects in columns of the Tung Chung West MTR station
“Stronger concrete needed to fix ‘basic mistake’ at MTR station columns: experts”
Forensic Headline Assessment: The original headline uses journalistic qualifiers such as 'basic mistake' in quotation marks; the sanitized version neutralizes the tone while maintaining technical accuracy.
Engineering specialists and Hong Kong authorities indicated that high-strength concrete can be used to repair some 30 defective columns at the Tung Chung West MTR station. The Buildings Department confirmed that the structures presented deficiencies in concrete pouring, although it ruled out immediate structural risks.
The defect, detected in columns where the concrete failed to reach the upper ceiling leaving reinforcing bars exposed, was described by experts as an operational failure by the contractor. Lawmakers and construction sector representatives pointed out that the use of materials such as non-shrink mortar will guarantee the required strength.
The MTR Corporation ordered the temporary suspension of rectification work carried out by the Bouygues-Dragages joint venture, demanding that it assume all resulting costs. Likewise, the Highways Department requested a detailed report within a two-week period.
The authorities assured that temporary supports remain in place and that correction works must be formally approved before continuing, maintaining the scheduled timeline for the Tung Chung line extension toward 2029.
