Railway settlements exceed limit

The Mass Transit Railway Corporation reported on September 2, that the construction works of the private development project at Kai Tak Area 1E Site 2 have been suspended after two settlement monitoring checkpoints exceeded the limit.
     The readings recorded in two settlement monitoring checkpoints installed inside the railway tunnel of the Tuen Ma Line Phase 1 had reached 20.1 millimetres on that day. The pre-set trigger level for works suspension is 20 millimetres. A site inspection conducted at midnight on September 4 reaffirmed the above readings. The Buildings Department deployed staff to inspect the affected railway tunnel and confirmed that it is structurally safe. The Electrical & Mechanical Services Department has reviewed the monitoring data submitted by the MTRC in relation to the railway’s safe operation and confirmed that the condition of the railway fulfils operational safety requirements.
     The building works concerned have not affected the structural safety of railway facilities and the railway's safe operation. Both departments and the MTRC will closely monitor the situation. The Buildings Department and the MTRC will request the registered building professionals responsible for the development project to formulate mitigation measures and adopt a construction method to alleviate the effects on the railway facilities.
