Programme Highlight

A tourist was struck and killed by a window fallen from high floor of a local hotel in the busy Tsim Sha Tsui shopping district in January 2019. Police arrested a hotel cleaner under a law against “allowing objects to fall from buildings and endanger or harm the public”. The accident sparked alarm that any window could possibly fall from the exterior of a modern hotel building in a city stacked with skyscrapers…..


In the wake of the above fatal accident, there are aspirations from the general public/building owners demanding quality prescribed window inspection and repair which are rendered safe under the law. Hitherto, about 500,000 Mandatory Window Inspection Scheme (MWIS) notices are issued and a small amount of voluntary MWIS inspections are conducted, and these are mainly carried out by Minor Works contractors, which are one of the registers of qualified persons that are natural persons. They are semi-skilled labour with limited technical knowledge; hence, they should be further trained and tested in order to undertake legal liabilities should accident happen. While guidelines are stipulated for the prescribed inspection/repair in the Code of Practice for MWIS as well as Practice Notes for Building Inspection (PNBI), the building owners may not be rest assured if their windows are properly inspected/repaired and certified by qualified persons who have sufficient technical knowledge and are capable of undertaking legal liabilities.


The seminar provides an in-depth review in the way how windows are inspected/repaired and rendered safe under the several aspects, i.e.

(i) Legal control under the Buildings Ordinance and Building (Inspection and Repair) Regulations;

(ii) Administrative control under the Building Authority;

(iii) Technical control through Code of Practice for MWIS and PNBI; and

(iv) Management control to supplement areas whereby technical control may not cover.
