| Summary: | Concrete is the most widely used material in the world. However, the use of
conventional concrete materials (cast in situ) has many challenges including long
project schedules, increased construction waste and many work accidents. This
underlies the development of precast concrete technology which is a priority
technology that must be developed in Indonesia. The level of application of the use
of precast concrete is not well defined, data regarding the level of its use is not yet
available. Therefore, it is essential to conduct this research in order to gain an
overview of the extent to which precast concrete components are used in the
construction of buildings and to determine the motivating and impeding factors that
affect their use. The level of use is defined as the frequency of use and the level of
usefulness. This study has a hypothesis that the use of precast concrete components
will be influenced by the type of building based on its height (number of stories)
and the benefits of using precast concrete have been felt by the contractors. Data
collection was carried out using a questionnaire instrument distributed to
contractors. It was found that precast concrete components in drainage work could
be standardized, while precast concrete components in substructure, retaining wall,
upper structure and architectural works needed increased use by promoting their
use in subsequent projects. There are several driving and inhibiting factors in the
use of precast concrete components. The motivating factor most respondents agreed
with was the desire to shorten the project schedule. While the most impeding factor
is the limited storage area for materials and equipment. |
