The Hong Kong Independent Commission Against Corruption received a corruption complaint from the Civil Engineering and Development Department earlier, and then launched an investigation. On May 16, the Hong Kong Independent Commission Against Corruption launched an operation codenamed "Green Park", arresting two senior contractors, two senior site laboratory technicians (senior technicians), 12 site laboratory technicians (technicians) and five laboratory attendants (waiters).
Chen Zeng, former director of the Hong Kong Geotechnical Engineering Office, said that it is necessary to understand the stage and scope of suspected fraud before assessing its impact. Chen explained that if ordinary cement reinforcement has been used in Hong Kong, the supplier will test it first, then test its chemical substance and strength when the construction contractor buys the relevant building materials, and finally it will be accepted by the material testing team of the public works department. If the fraud involves the import test of new materials, the cement reinforcement involved may be used in other projects, which is even more implicated.
The Civil Engineering and Development Department of Hong Kong has hired contractors to conduct stress tests on concrete samples used in the Hong Kong-Zhuhai-Macao Bridge project since June 20 13. The test of each concrete sample must be carried out within a specific time, but all concrete samples (sample bricks) must pass the test.
The Hong Kong-Zhuhai-Macao Bridge connects Hong Kong, Zhuhai and Macau with a total length of12km. Construction started in 2009 and is expected to be completed and opened to traffic by the end of this year. When completed, it will be the longest sea-crossing bridge in the world. An investigation by the Hong Kong Independent Commission Against Corruption showed that some tests were not completed within a certain period of time as required by the contract, and the technicians and waiters involved were suspected of adjusting the time displayed on the test equipment to cover up their violations.
In addition, during the operation, the Hong Kong Independent Commission Against Corruption found that some laboratory personnel were suspected of using metal calibration columns and/or solid concrete bricks instead of concrete samples to falsify the test results to make the test look normal. The above violations are suspected to have occurred before the beginning of 20 15.
An investigation by the Hong Kong Independent Commission Against Corruption found that two senior technicians involved in the case were responsible for verifying false test reports. They were suspected of corruption and connived at submitting false test reports to the Civil Engineering and Development Department of Hong Kong.
The Civil Engineering and Development Department of Hong Kong previously found that the concrete pressure test report was abnormal, and the contractor involved conducted an internal investigation on this matter. However, the investigation report submitted to the Civil Engineering and Development Department did not disclose the problem of using metal correction columns and/or solid concrete bricks for false testing. The Hong Kong Independent Commission Against Corruption said that the contractor was suspected of submitting misleading investigation reports to defraud the Civil Engineering and Development Department.
According to Sing Tao Daily, 2 1 men, aged between 20 and 60, were arrested. This action is handled by Group C of the Action Department of ICAC. * * * Fifty investigators were sent to take action, arrested them in their homes and applied to the court for 20 search warrants to search their apartments and contractors' offices.
