Residents of a Fanling estate where a balcony collapsed on Christmas Eve were yesterday warned their homes were also in danger. The Buildings Department said on Monday the collapsed balcony in Swallow Garden did not meet safety standards, but ruled out immediate danger in the other blocks. However, after taking samples from the third-floor balcony which collapsed, the department said the other three-storey blocks were a potential danger. Senior structural engineer Leung Siu-man said: 'Following the preliminary investigation, there is a potential danger, but it is not imminent.' Sammy Chan Yin-nin, assistant professor at the Polytechnic University's civil and structural engineering department, said cracks on the balconies of two blocks he inspected yesterday were signs the structures had moved. 'There are signs the balconies have tilted downward. They are definitely structural cracks,' he said. But Director of Buildings Dr Choi Yu-leuk said inspections conducted by his department had not revealed any structural cracks. Dr Choi said some cracks were observed in the parapet walls, but these were not structural walls. He said the department would advise owners to remove floor tiles at critical locations between the balcony and main structure to search for any structural cracks. 'If there are structural cracks, we advise the owners to carry out an investigation,' Dr Choi said. Fong Shiu-wing, one owner whose balcony collapsed, said last night the department had not told him of the preliminary results of its investigation. He heard about it on the television news. 'I hope the Government can find out the truth behind the problems,' he said. Both the Buildings Department and Swallow Garden's owners have been unable to contact the developer, Safe Energy, or the construction company. The Heung Yee Kuk yesterday voted to oppose a legislator's demand for stricter controls on building of village houses following the balcony collapse. Homes built under the so-called 'small house' policy are exempt from safety checks. Villagers can move in after obtaining a certificate showing they have complied with the building licence. Vice-chairman Lam Kwok-yin said: 'It is impracticable to check all the village houses. It would also cause panic.'
