I refer to the letter by R. Wong ('No need to relocate school', July 28). The relocation of Lingnan Primary School, Kindergarten and Nursery is due to a number of reasons.

First of all, unauthorised building works, including an entire basement floor and alterations to stairs and exit routes, were found in the school premises. These works might affect the structural integrity, and 'the safety of pupils, teachers and other personnel at the premises is considered to be jeopardised', according to the registered engineer who conducted the site survey. Second, the old retaining wall on the slope behind the school requires reinforcement. Third, construction works on the former Lingnan college site adjacent to the school are expected to commence.

The Lingnan Education Organisation (LEO) was advised by the Education Bureau that the Buildings Department had conducted a site inspection in June. The LEO was told that while the focus of the inspection was primarily to identify unauthorised building works, a 'cursory review' of the buildings indicated they were in a stable condition. However, the bureau also advised that some unauthorised building works on site were noted by the department, and 'enforcement action would be taken according to the' department's enforcement policy which came into effect on April 1. The LEO has not been informed by the department that, despite the illegal structures in the school premises, the building is safe and suitable for the purpose of school premises under the Education Ordinance. The school would have no option but to demolish the unauthorised structures and restore the building to its original state.
