and validation to the regulations, specifications,
calculations, dimensional tolerances have been
made. In addition, the consultants should review all
risk evaluation reports to ensure that the products
have not contributed to, or have caused problems
later on during the construction phase.
During the construction stage, proper steps
must be taken to ensure that all personnel involved
in the execution, inspection, supervision and
management of the project possess the relevant
and requisite competency, skills, expertise and
knowledge. Lastly, but not least safe engineering
practices must be upheld at all times during the
duration of the construction work.
In the case of demolition work, available
standard MS 2318: 2012: Demolition of
Buildings-Code of Practices should be followed
by all parties involved in the work. Complete and
detailed construction drawings for the building or
engineering structure to be demolished with the
structural stability analysis report and dilapidation
survey report (if available) that have been
undertaken to be handed over by the client to the

contractor or its appointed consultant.
The failure and incident cases that have
occurred in the construction industry covering a
period of 20 years bring into focus the low priority
placed by the industry stakeholders. There were 20
serious incidents which caused 74 fatalities and
54 injuries from 1993 to 2013 (Table 1.0). Except
for the Highland Tower incident that occurred postconstruction, all other incidents occurred during
the construction of the projects.

Collapse and failure of
heavy lifting machinery
In recent years there have been several cases of
serious tower crane failures and sudden failure of
lattice boom members of crawler cranes (Photo
2.0) in construction sites around the Klang Valley.
In the latter case, it was determined that the failed
machine had undergone extensive and improper
repairs and welding on the lattice load bearing
members.
