Learn from building defects
21/05/2007 The Star
DEFECTS in new buildings or structures are so common that Malaysians do not
bat an eye anymore, or one could say they are immune to news of these
defects when highlighted.
The conundrums are, firstly, the construction integrity of the structures,
shoddy quality of workmanship and supervision, and, secondly, the
maintenance of these structures. The construction integrity relates to the
ability of the buildings or structures to sustain its loads or function as
designed or required structurally.
The quality of the workmanship is another aspect that has been giving
contractors a bad name. The Construction Industry Development Board (CIDB)
is supposed to wrestle this issue by requiring all relevant labourers or
those in a similar trade to undergo a skills training programme conducted by
the CIDB Academy.
However, it is well established that Malaysia is not only facing an acute
shortage of skilled labourers but also unskilled ones as well.
What makes it worse is that most of these labourers are from a foreign
country and most likely were farmers all their lives and have never been
involved in construction. They probably have never seen a building plan, and
now we are expecting them to put the reinforcement steel correctly!
Now one might ask, how were these defective buildings/structures allowed to
be occupied assuming that they have met the requirements of building by-laws
and are certified fit for occupation.
For one, lack of enforcement and supervision contributed to these defects.
However, a good project management team acting on behalf of the client
should be able to look after the interest of its clients by making sure the
contractors do not compromise on the quality of the workmanship through its
resident engineer.
As far as maintenance is concerned, our industry is one step behind the
developed countries where service life planning is carried out in accordance
to ISO15686 during the design stage. Interestingly enough, Malaysia is a
member of the drafting of the ISO through SIRIM.
Traditionally, we are only concerned with the financial burden of getting
the building erected and we are not made aware of the yearly maintenance
cost, the operational cost and replacement cost.
At times, the total cost of these three elements might surpass the
construction cost. Insertion of life cycle assessment and costing during the
design stage can save building owners from a lot of trouble and financial
burden.
Efforts by Jabatan Perumahan Negara, Ministry of Housing and Local
Government, to embark on developing a software to assess the life costing of
its multi-storey low-cost housing should be lauded. The first phase of the
software, LICCOMS, was launched by the minister himself.
Malaysians should learn from the defects in buildings/structures and include
service life planning in the design process. However, this will only be
successful if the relevant authorities are willing to change the current
practice.
