In the article “3D building
models help bring sustainability into construction”, (Jenkins, 2015) discusses
the effectiveness of building information modelling (BIM) as well as the
challenges faced when implementing it. The introduction of BIM has revolutionized
the building construction industry. According to Monswhite (as quoted in
Jenkins, 2015) the change of use from two to three-dimensional design with BIM
allows the industry to reduce construction cost and optimise space management.
While BIM boast of its advantages, Jenkins asserts that BIM is yet to be widely
accepted in the building construction industry. This is supported by Charlton,
chief of consultancy Space Group, who argues that majority of the key players
in the project lack collaboration and refuse to embrace changes and prefer to
stick to conventional methods. In addition, Smithson, Coventry’s University
sustainability director, states that these key players are unwilling to even
give BIM a try. Therefore, Smithson and her team are operating an immersive
simulation centre to showcase the benefits of BIM to industry professionals to
convince them to implement BIM. However, if BIM really is the key to revolutionizing
the build construction industry, there must be deeper reasons why not everyone
is using it or even willing to try it.
One main reason is due to
the hefty price of BIM. This is supported by Than, Singapore-listed Lian Beng
Group construction director who stated in an article that it is a challenge for
everyone to use BIM as it is expensive. It is true indeed as according to
Autodesk official website, the software itself costs a few thousand and this is
exclusive of the hardware and training charges. In Singapore, the government
highly encourages the usage of BIM in projects and to show its support, the BIM
fund was launched to help defray some of the incurred fees. However, according
to (BCA, 2017) getting subsidized is not as straightforward as there are
several requirements to be met before funding can be received. Furthermore, as BIM is a
complex software, staffs will have to take time off from work to attend trainings.
This will be especially taxing on firms lacking manpower. Alternatively, firms
can hire BIM experts but this of course comes with a hefty price. Based on an
article from The StraitsTime by (Wong, 2017) hiring an operator to work the BIM
system could cost $4,000 to $5,000 a month.
Apart from financial
burdens, another concern would be that in order for BIM to be implemented, the
work process need to be changed as BIM requires the collaborative work of all
the various disciplines. In conventional practice, each department would just
have to focus on submitting their own plans. With BIM, the various departments
need to interact and come out with the collaborative model together. In this
case, the role of the project coordinator is chiefly critical to ensure the
smooth integration of the project and this may be an issue if the project
coordinator is not BIM-trained.
In conclusion, although there
are many complications that could potentially hold firms back from implementing
BIM but the main problem is still financial constraint. In addition, smaller
firms that are unable to afford this software are facing more pressure with the
increasing government contracts requiring BIM’s implementation. Thus, as the government
is encouraging BIM’s implementation, they should do a better review and
inspection as to why not everyone is using it even with the funding and
incentives.
