A human rubber stamp In line with the contract, Hui Hon employed a quality control engineer to inspect every item of works to ensure compliance. The quality control engineer told ICAC investigators that he was supposed to conduct quality control at the Yuen Chau Kok site, but in fact spent most of his time at another construction site. He said that the two ex-directors of Hui Hon were aware of his heavy work load. Over a period of several months, he carried out very few inspections at Yuen Chau Kok site. He admitted that he had signed a number of confirmation documents without having actually checked the quality of the works. He was merely a rubber stamp.
