Peningkatan Produktivitas Konstruksi Melalui Pemilihan Metode Konstruksi
Abstract: Productivity growth
in the construction is lower than that of in the industry sector. Level of
innovation in this sector is too low. Many problems of inefficiency in the
construction process are a lotof waste of resources that do not produce value.
According to LCI (Lean
ConstructionInstitute) waste in the construction industry is about 57% while
the activity that adds value is only 10%. The construction industry has a lot
to learn from manufacture industry. Some innovations by applying an appropriate
and efficient methods in the field of
construction adopted many of the manufacturing, including modular
systems/fabrication (precast concrete). Construction materials are mass produced
in acontrolled environment and then assembled inthe site. The use of precast on
any project shows that there are advantages obtained are: cheaper, faster/more
productive and guaranteed quality. The duration of the Rusunawa (Simple Flats
for Rent) Structure construction phase in Cilacap for precast method is 168
days while for the implementation of the conventional method is 196 days. The
duration of the construction of precast structures is faster 28 days (14%)
faster than that of the conventional structures. In high-speed rail project on
the border of Belgium and the Netherlands, use Rheda 2000 NL method, which
development of Rheda method, can increase productivity and lower overtime costs
as 24.6%. In the residential case, quicklyconstructed building criteria can be
categorizedinto several aspects, such as dimensions, weight components and
connection systems.The suitable selection criteria will accelerate instalment
proses of the wall panel.
