3.4       SHORTFALLS OF THE UBBL

1. The Uniform Building By-Laws, 1984 [UBBL] was established out the need for a standardised set of building regulations for the country.   However, despite the federal government gazetting the UBBL in 1985, the reality is that until today the use and interpretation of the UBBL are anything but uniformed.   The enforcement of UBBL is governed by the states and hence gazetted separately with slightly different versions for each of the states.
2. As the UBBL is a state matter, many Local Authorities and Technical Departments have their own readings and interpretation of the UBBL.   The differences in the translations between the English and Bahasa Melayu versions also added to the confusion.   Hence, there is a need to re-look into the intents of the UBBL and persuade all state governments to agree to a “Local Authorities’ Endorsed” standardised explanatory notes.   To that effect, the fire department had produced two definitive books on their interpretation of the fire protection system’s requirements which had become very useful references for designers.
3. The continual advances in constructional technologies and sciences have made some of the by-laws within the UBBL “out-of-date”.   For instance, Malaysia has experienced rapid development over the last two decades.   Large-scale structures, like new airports, shopping centres and mixed developments, have been built with new concepts and design approaches.   The existing UBBL and other Fire Safety codes are not applicable to these structures.   Hence, there is a need for the UBBL to be updated to reflect the “state-of-the-art” and make allowances for the by-laws therein to be amended to allow continual adaptation to suit the ever-changing times.  The Fire Safety- Performance Based Approach has been officially adopted in 2002 by the Fire and Rescue Department, Malaysia [Bomba] to solve some of these shortfalls.   The approach, which has been widely practiced overseas, is a scientific and engineering-based method whereby the determination of type and standard of fire safety protection systems required specific testing and research.
4. There are by-laws within the UBBL which had not been referred to by professionals and/or found to be irrelevant.   As an example, a good number of sections under the structural requirements have been ignored and not referred to by structural engineers since most are using the British Standards as their main design guide.   Therefore, it is best to re-look these sections and decide whether to have these clauses repealed or amended to suit the times.
