Opening-up investigation in second stage of holistic assessment strategy for Hung Hom Station Extension under Shatin to Central Link Project

     â€‹The Government received a proposal on March 8 from the MTR Corporation Limited (MTRCL) for the enhanced Phased Array Ultrasonic Test (PAUT). After discussions with the Government, the MTRCL submitted the final proposal on March 13. The Government accepted the proposal today (March 14), and the opening-up investigation in the second stage of the holistic assessment strategy for Hung Hom Station Extension under Shatin to Central Link (SCL) Project continues.
      
     According to the holistic assessment strategy of the MTRCL regarding the platform slabs and diaphragm walls of the Hung Hom Station Extension under the SCL Project accepted by the Government on December 5, 2018, the MTRCL proceeded to commence the relevant work on December 10, 2018. The purposes of opening up the concrete are:    
    

  1. Physical investigations will be carried out at locations with gaps in the construction documentation, so as to verify the as-constructed condition of the connections between the platform slabs and diaphragm walls; and
  2. In view of the allegations on the cutting-short of steel bars, the MTRCL needs to open up certain connections between the platform slabs and diaphragm walls for detailed inspection, and to conduct non-destructive tests (PAUT) to determine the embedded length of the threaded steel bar inside the coupler.

     The opening up works of the holistic assessment strategy stage 2 started on December 10, 2018 and are still in progress. A large deviation was observed between the embedded length measured using PAUT up to January 29, 2019, as well as the direct measurement after cutting the rebar with the coupler connected. The Government immediately requested the MTRCL to investigate the root causes of such a deviation.
      
     The MTRCL and its technical team have conducted a detailed investigation of the incident, and carried out an in-depth study and enhanced the PAUT in order to improve its accuracy and reliability. The MTRCL also conducted validation on the enhanced PAUT. During the investigation and validation process, the Expert Adviser Team of the Transport and Housing Bureau, the expert team from the University of Hong Kong, the Highways Department and the Buildings Department provided comments to the MTRCL.  
      
     The enhanced PAUT has been repeatedly trialed and validated in laboratories and on-site by the MTRCL. The results of validation reveal that, compared with the enhanced PAUT results, all the direct measurements of the embedded length of the threaded steel bar inside the coupler fall within the 3 millimetres’ allowable tolerance of PAUT results. In view of the above results, the Government accepted the proposal from the MTRCL to continue with the use of the non-destructive test in the stage 2 investigation with a view to minimising damage to the structure. 
      
     The Government acknowledged that the MTRCL would resume testing on March 15 using the enhanced PAUT on the exposed (including previously tested and yet-to-be-tested) couplers. The Government will continue to closely monitor the investigation works. The on-site test results will be verified by the laboratory the next day, and the verified test results will be announced in a timely manner on the Highways Department’s website for the SCL project for public reference (www.hyd.gov.hk/en/road_and_railway/railway_projects/scl/index.html). read more

CHP investigates influenza A outbreak at primary school in Wan Chai

     The Centre for Health Protection (CHP) of the Department of Health is today (March 14) investigating an influenza A outbreak at a primary school in Wan Chai, and again reminded the public to maintain strict personal and environmental hygiene against influenza.

     The outbreak involves 23 boys aged 6 to 11 who have developed fever, cough and sore throat since February 20. All of them sought medical attention but none required hospitalisation. All patients are in a stable condition. The respiratory specimen of one student tested positive for influenza A upon laboratory testing.

     Officers of the CHP have conducted a site visit and advised the school to adopt necessary infection control measures against respiratory tract infections. The school has been placed under medical surveillance.

     A spokesman for the CHP said, “To prevent outbreaks of influenza and other respiratory infections, it is of prime importance that students with fever, regardless of the presence of respiratory symptoms, should not be allowed to attend school. They should seek medical advice and avoid school till 48 hours after the fever has subsided. Schools should also measure and record students’ body temperature properly.”

     Schools are reminded to follow the Guidelines on Prevention of Communicable Diseases on preventive and control measures as well as management of outbreaks, which should be reported to the CHP for prompt follow-up.

     “The latest surveillance data showed that the local influenza activity has continued to decrease from the peak level in January but remained above the baseline threshold. We urge the community to continue heightening its vigilance against seasonal influenza. As young children are particularly affected in this influenza season, we appeal to parents who have not yet arranged vaccination for their children in this season to do so as soon as possible to strengthen their personal protection,” the spokesman said.

     Apart from children, people aged 50 to 64 years, the elderly and those with underlying illnesses who have not yet received influenza vaccination this season are also urged to get vaccinated as early as possible to prevent seasonal influenza as it takes about two weeks for antibodies to develop in the body after vaccination. Medical advice should be sought promptly if influenza-like symptoms develop so that appropriate treatment can be initiated as early as possible to prevent potential complications. Parents and carers are reminded to render assistance in prevention, care and control for vulnerable people.

     Besides receiving seasonal influenza vaccination as early as possible for personal protection, the public should maintain good personal and environmental hygiene for protection against influenza and other respiratory illnesses.
