Station sinking limit eased to allow Tin Shui Wai flats projectLocal | 24 May 2019 6:42 pm
Construction work will resume at a private residential project in Tin Shui Wai, after the government substantially relaxed the tolerance limit for subsidence at a Light Rail stop nearby, RTHK reports.
Piling work for the Sun Hung Kai Property project was suspended in June last year after subsidence at the Tin Wing LRT stop reached 80 millimeters.
But the rail facilities had continued to sink, and according to documents submitted to the Yuen Long District Council, they have sunk a total of 96 millimeters as of May 7.
However, a government spokesman said an analysis by the project's structural engineer found that even if the platform has sunk 150 millimeters, its structural safety would not be affected.
He said government engineers, as well as the MTR Corporation, agreed with the analysis, and have therefore relaxed the tolerance limit to 150mm.
Work for the residential project will resume in phases from next Friday.
The developer would have to start with grouting works as part of the mitigation measures.
It will also have to assess the effectiveness of those measures and submit a report to the Buildings Department, which will then decide if the project could be completed.
Officials added that, among other things, the developer is asked to submit monitoring data on subsidence on a monthly basis, and they will follow up on the situation closely.-Photo: RTHK
