China, Hong Kong: South China Morning Post reported that serious design flaws in the immigration building of the Hong Kong-Zhuhai-Macau mega bridge could be deadly for workers, as power supply rooms are located in the basement prone to water seepage.
The warning came after video footage appeared showing serious flooding and water seepage in a basement on the Hong Kong side of the bridge, where the transformer room and switch room are located.
Civil and structural engineer Mr. Simon So Yiu-kwan said that placing the transformer room and the switch room in the basement was a serious design flaw.
“Usually the transformer room and switch room are located on the ground floor, not the basement as that is where water leakage easily crops up. The basement of the passenger clearance building is prone to underground water leakage problems as it is built on an artificial island surrounded by sea. Its transformer room and switch room should not have been placed in the basement,” said Mr. Simon.
According to him, the best way to resolve the issue would be to relocate both rooms to the ground floor, but this move would take at least three to four months, making it impossible for the bridge to open this year.
