The construction industry plays an important role in establishing the
infrastructure required for socio-economic development and directly
contributes to economic growth. On the other side, it also generates
severe impacts on the environment. The construction industry is one of
the biggest environmental polluters and it also consumes large
quantities of raw materials. Value Engineering originates from the
manufacturing industry in order to deliver higher value and quality to a
product by means of an increase in efficiency. ‘Lean Construction’ (LC)
concepts emerged as a consequence of the application of VE philosophy,
specifically for construction industry. LC extends from the objectives
of a lean production system – to maximize value and to minimize waste –
in relation to specific techniques and then applies them conceptually in
a new project delivery process. The aims of this paper are to present
practical examples of the application of Value Engineering and Lean
Construction concepts within a green building construction project and
to qualitatively assess its benefits in terms of environmental impact
and waste minimization. A detailed case study was conducted for project
execution of a new multi-storey government institutional building in the
Jakarta central business district. This project adopts a Green Building
and a Green Site concept in order to reduce potential environmental
impact during the construction phase itself and during the occupancy
phase of the building. The case study primarily concerns issues such as
water consumption, power usage, etc. This project is a perfect example
for the application of Value Engineering and Lean Construction
philosophies in order to deliver better quality, faster completion,
environmentally friendly practice, and less waste generation. The
adoption of environmental awareness in the context of building design,
the application of alternative and/or recycled/environmentally friendly
materials, along with a number of “green” technologies and building
systems featured in this building concept will deliver greater value
without jeopardizing the ecology. Meanwhile, the adoption of
prefabrication construction methods, intelligent excavation works,
‘Reduce-Reuse-Recycle’ principles, and simple ‘environmentally-aware’
on-site practices can minimize the waste produced and the local
environmental impact emitted during project execution.
