Abstract

This study aims to evaluate the performance of steel pile foundations for the abutment of the Sei Ella 1 Bridge, located at the Ela River, West Kalimantan, with soil conditions consisting of sedimentary layers. The analysis was conducted based on actual piling conditions, where pile depths vary between 4.015 meters and 5.823 meters. The evaluation includes calculating the single pile bearing capacity using the Decourt method, analyzing group pile capacity with the efficiency group approach, and assessing lateral deformation and settlement using the Finite Element Method (FEM). The results show that the single pile and group pile capacities are sufficient to withstand the loads from the superstructure, abutment self-weight, and lateral soil pressure. The lateral deformation analysis yielded a deflection value of 2.83 mm, while the settlement was recorded at 0.1152 mm. Both values are well below the maximum limit set by SNI 8460:2017, which is 12.5 mm, indicating that the foundation is in a safe and stable condition. This study provides a deeper understanding of the performance of steel pile foundations for the abutment of the Sei Ella 1 Bridge. As an additional verification step, it is recommended to conduct Static Loading Tests (compressive, tensile, and lateral) to validate the analysis results. This approach offers a robust foundation for ensuring the safety, stability, and feasibility of the design under actual conditions..

Abstract

Industri konstruksi di Indonesia saat ini berada di persimpangan jalan yang kritikal. Di satu sisi, agenda pembangunan infrastruktur nasional yang masif menuntut kecepatan dan presisi; di sisi lain, praktik manajemen konvensional yang terfragmentasi sering kali menghambat produktivitas dan transparansi. Artikel ilmiah ini menyajikan analisis mendalam mengenai dampak transformasi digital, khususnya penerapan Building Information Modelling (BIM), sistem pelaporan berbasis cloud, dan teknologi inspeksi digital, terhadap tiga pilar utama manajemen proyek: efisiensi pelaporan, inspeksi mutu, dan kontrol biaya. Menggunakan pendekatan metode campuran yang menggabungkan data empiris dari survei terhadap 57 praktisi konstruksi dengan meta-analisis literatur global dan nasional, studi ini menemukan korelasi positif yang signifikan antara adopsi digital dengan kinerja proyek. Hasil analisis menunjukkan bahwa digitalisasi mampu meningkatkan aksesibilitas laporan (skor efektivitas 4.5/5.0) dan efisiensi pengendalian biaya (4.4/5.0). Namun, studi ini juga menyoroti paradoks adopsi di Indonesia, di mana tantangan sumber daya manusia dan interoperabilitas sistem masih menjadi penghambat utama di tengah dorongan regulasi yang kuat dari Kementerian PUPR. Laporan ini memberikan peta jalan strategis bagi pemangku kepentingan untuk menavigasi transisi menuju ekosistem konstruksi yang terintegrasi penuh.
