Abstract

Timely completion of a construction project is one indicator of project success, whereas delays tend to increase execution costs and postpone the utilization of the building. This study aims to analyze the execution duration and critical path of the existing condition of the construction project of the North Sulawesi Regional Police building, and to calculate the magnitude of time acceleration and the percentage of duration efficiency achievable through the application of the fast track method. The study used a descriptive quantitative approach with secondary data consisting of the master schedule/S-curve, weekly and monthly reports, network diagram/precedence diagram method (PDM), and the project budget plan. The analysis was carried out in stages, including identification of activities and durations, preparation of the network diagram and determination of the critical path using Microsoft Project software, analysis of the potential for activity overlapping on the critical path, and rescheduling of the project. The results show that the project execution duration under field conditions was 160 working days. After the fast track method was applied to several critical path activities by changing the predecessor relationship from finish-to-start to start-to-start, the project duration could be shortened to 137 working days, an acceleration of 23 working days (14.4%). This study concludes that the fast track method is effective as a strategy for accelerating the execution time of multi-story building construction projects without a significant increase in resources, provided it is accompanied by adequate coordination and quality control.

Abstract

Kondisi geometrik jalan merupakan salah satu faktor penting yang memengaruhi keselamatan, kenyamanan, dan kinerja kendaraan pada suatu ruas jalan. Ketidaksesuaian parameter geometrik seperti radius tikungan, kelandaian memanjang, dan superelevasi dapat meningkatkan risiko gangguan keselamatan lalu lintas. Penelitian ini bertujuan untuk mengevaluasi kondisi geometrik eksisting pada ruas Jalan Manado Outer Ring Road 1 berdasarkan kriteria Pedoman Desain Geometrik Jalan Tahun 2021. Metode penelitian yang digunakan adalah kuantitatif evaluatif dengan memanfaatkan data primer hasil pengukuran lapangan dan data sekunder sebagai pendukung analisis. Pengukuran topografi dilakukan menggunakan GPS Geodetik/Real-Time Kinematic (RTK), kemudian data diolah menggunakan perangkat lunak AutoCAD Civil 3D untuk memperoleh parameter geometrik jalan. Hasil penelitian menunjukkan bahwa kondisi geometrik eksisting belum sepenuhnya memenuhi standar yang ditetapkan. Pada aspek alinyemen horizontal, Tikungan 2 memiliki radius 239 m yang berada di bawah batas minimum 250 m. Pada aspek superelevasi, Tikungan 3 jalur kiri memiliki nilai maksimum sebesar 12,42%, melebihi batas 8%. Selain itu, ditemukan beberapa segmen dengan kelandaian memanjang lebih dari 6%, yaitu pada beberapa STA antara 0+525 hingga 4+300. Temuan ini menunjukkan perlunya evaluasi dan penanganan geometrik lebih lanjut untuk meningkatkan aspek keselamatan dan kenyamanan pengguna jalan. Penelitian ini dapat menjadi dasar pertimbangan teknis dalam perbaikan desain maupun pengelolaan ruas Jalan Manado Outer Ring Road 1.
