如何投訴則師樓&其註冊結構工程師?

I wish to supplement Wilson's answer.

Authorised Persons (AP) and Registered Structural Engineers (RSE) are not registered under ERB although individually these professional persons might be registered under ERB in the capacity of Registered Professional Engineers. AP & RSE are recognised under the Buildings (Administration) Regulation and are registered under the Building Authority. You should make your complaint direct to the Building Authority through the Buildings Department. This relates to their licence to practice.

In addition to the above, if you are complaining against their professional negligence or breach of professional conduct, you can make a complaint to the respective professional body of which they are a member. Architects are mostly members of the Hong Kong Institute of Architects whereas engineers are mostly the Hong Kong Institution of Engineers. Please note that some APs are primarily engineers or surveyors, not necessarily architects.

Engineers Registration Board

As a consequence the Engineers Registration Ordinance was enacted in 1990. Since then some 1700 engineers registered in 16 disciplines. The functions of the Engineers Registration Board under the Engineers Registration Ordinance are related to the process of Registration, Qualifications for Registration, Disciplinary Proceedings and Procedures of the Board. The functions of the Board as outlined in Section 7 of the ordinance, chapter 409 are as follows:
