| dc.description.abstract | Bored pile foundations in construction projects often experience
deviations, one of which is the change in pile diameter, which can
manifest as necking or bulging. These deviations can be caused by
various factors, including discrepancies between the planned and actual
concrete volumes poured, differences in pouring rates, or soil conditions
that do not align with initial assumptions. This study aims to evaluate the
relationship between concrete pouring dimension deviations and changes
in pile diameter in the Yogyakarta-Bawen Toll Road Section 1 project.
Concrete pouring dimension deviation, defined as the difference between
the planned and actual poured concrete dimension, is used as an
indicator of the potential for pile diameter changes. Through the analysis
of field data, this study found a correlation between concrete pouring
dimension deviations and variations in pile diameter. The greater the
pouring dimension deviation, the greater the likelihood of significant
changes in pile diameter. These changes in pile diameter can reduce the
pile's bearing capacity and potentially compromise the stability of the
structure. This research shows that these deviations not only violate the
terms of the contract but also contradict the quality standards set out in
the Act Number 2 Year 2017 on Construction Services. This study
highlights the importance of strict quality control during the concrete
pouring process to minimize deviations in pile diameter.
Recommendations include increasing the accuracy of concrete volume
planning, closely monitoring the pouring process, using appropriate
equipment, and improving concrete quality. | en_US |
