LESSON FROM COLLAPSED HIGHLAND TOWER BUILDING

 There are 56 nos of building are collapsed between 1992 to 2019.The worst is in the 2018 wereby 7 building were effected,2013, 6 nos of building were effected and 2006 ,5 building were effected.There are several factor where contributed for the collapsed.There are:

• Heavy rainfall or snowfall
• Landslide
• Design Error
• Roof structure
• Demolition work
• Gas explosion
• Histroric building
• Over loading
• Under construction
• Poor workmanship
• Added floor
• Nearby river
• Bombing or terrorist attacked

In Malaysia there are 2 building collapsed ;

• Taman Hill View-20 November 2002-8 people killed
• Highland Tower-11 December 1993-48 people killed

In this topic,only HIGHLAND TOWER tragedy was discussed:

• 1.35 pm on December 11.1993
• 3 nos of 12 storey residential were effected
• 1 collapsed,2 declare unsafe until now
• retaining wall and drainage poorly design and maintained
• on the top began construction,start erosion
• mud  clogged the discharge pipe
• start water clogging and seepage
• diversion stream to the discharge pipe are in the building
• pipe burst and 100,000 m3 mud start produce line of failure
• 10 days non stop rain
• cracking start appeared at road and surrounding area
• retaining wall burst and mud start hit the foundation of building
• block 1 collapse
• 48 people killed

what are the lesson can get from this disaster:

• no periodically inspection of the building
• completed in 1971,tragedy 1993,that mean 23 years without building inspection that is my prediction 
• akta jalan,parit dan bangunan 1974,seksyen 85A menyatakan bangunan yang melebihi 5 tingkat dan usia bangunan melebihi  dari 10 tahun hendaklah di periksa keadaan struktur dan sekitarnya oleh seorang jurutera profesional yang di lantik.Please refer to the AKTA 133.
• my opinion the duration 10 years must change to 5 year for urban area or critical area like near slope and river to prevent this type of tragedy
• the goverment must stringently enforce this Section 85A immediately
