Penyimpangan penerapan aspek kontrak dan hukum konstruksi pada pekerjaan fondasi bored pile

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.
