Senior housing officials are expected to face disciplinary action after a report apportioning blame for a public housing project scam in Sha Tin is released tomorrow. The discovery of short piles at a Home Ownership Scheme project in Yuen Chau Kok left the Government no choice but to demolish two new 34-storey blocks. After the scam was discovered in January, an independent report released in mid-March confirmed most of the 36 piles supporting the blocks were too short. The Independent Commission Against Corruption has arrested and charged eight suspects, including three Housing Department staff. The two blocks are so close to a secondary school that sound baffles must be in place before demolition work starts late next month or early in July. The committee will be briefed by an independent three-member panel tomorrow on accountability for the piling scandal. Senior housing officials are expected to be held responsible for their lack of supervision, according to a source close to the committee. Committee members would 'most likely follow advice in the report when considering what action needs to be taken' against individuals within the department, the source said. Legal action against contractors is also an option, a move supported by committee members and the department. The scandal is expected to cost taxpayers $250 million in construction and demolition bills. Piling contractor Zen Pacific has denied responsibility, claiming it was just another victim of the scam. The panel, led by John Strickland, head of the Hongkong and Shanghai Banking Corp from 1996 to 1998, will also submit the report to Chief Executive Tung Chee-hwa and Legco.
