Upheaving of footbridge of Chai Wan Station
A Government spokesman said today (February 3) that the MTR Corporation Limited (MTRCL) reported on February 1 that while the grouting works for the excavation and lateral support works of the private development project at 18 Lee Chung Street, Chai Wan were being carried out, upheaving of 24 to 33 millimetres was recorded at five monitoring checkpoints installed on the MTRCL's footbridge connecting Ning Foo Street and Chai Wan MTR station, exceeding the pre-set trigger level for works suspension (i.e. 20mm). The relevant works of the development project were suspended.
The Buildings Department (BD) deployed staff to inspect the affected footbridge on February 1 and confirmed that the footbridge is structurally safe. The Electrical and Mechanical Services Department (EMSD) has reviewed the monitoring data submitted by the MTRCL in relation to safe operation of the railway and confirmed that the condition of the railway fulfils the operational safety requirements. The works concerned have not affected the structural safety of railway facilities and safe operation of the railway.
The BD, the EMSD and the MTRCL will continue to closely monitor the situation to ensure the structural safety of railway facilities and safe operation of the railway.
While the relevant works of the development project have been suspended, the BD and the MTRCL has requested the registered building professionals responsible for the project to formulate mitigation measures and adopt a construction method that would alleviate possible effects on the railway facilities.
Upon receipt of the proposed mitigation measures or amendment plans of the development project and application for resumption of works, the BD will vigorously scrutinise the proposals with a view to ensuring structural safety of railway facilities, including consulting the MTRCL and other relevant government departments. The EMSD will also confirm that the MTRCL has put in place stringent monitoring measures to ensure the safety of the railway operation. Moreover, if the registered building professionals propose that the pre-set trigger level(s) for works suspension be revised, the BD will consider the proposal having regard to the circumstances after consulting the MTRCL and other relevant government departments. When the application for resumption of works has been agreed, the BD and the EMSD will make an announcement to the public about the decision.
