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 lot of waste of resources that do not produce value.
According to LCI (Lean Construction Institute) 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 a controlled
environment and then assembled in the site. The use of precast on anyproject
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, quickly constructed building criteria can be categorized
into several aspects, such as dimensions, weight components and connection
systems. The suitable selection criteria will accelerate instalment proses of
the wall panel.
