Abstract
Construction projects often face challenges in terms of delays in completion, which have an impact on decreasing contractor performance and project implementation time effectiveness. These delays are often caused by a lack of efficiency in project scheduling, which generally aims to minimize process time, waiting time, and inventory levels, and optimize the use of facilities, labor, and equipment. In this context, project effectiveness is measured through three main criteria: scope, time, and cost. This study analyzes the application of the Critical Chain Project Management (CCPM), Bim 3D, and Last Planner System methods in high-rise building projects. This method uses SPSS 27 and SEM-PLS 3.0 software to process data. The influencing factors are Critical Chain Project Management (CCPM) (X1), BIM 3D (X2), Last Planner System (LPS) (X3),contractor performance (Y1), and implementation time (Y2). The critical chain project management method further optimized the initial 314-day time planning analysis using Microsoft Project to 235 days, resulting in a 33.4% improvement in the project's implementation time. The results of SPSS data processing with the CCPM, BIM, and LPS methods simultaneously obtained a significant value of 0.000 <0.05, which means that it affects contractor performance and project implementation time. Then the implementation planning with BIM software obtained the visualization progress of the implementation of building work on each floor. The Last Planner System analysis method obtained a percent plan completed (PPC) of 89.49%. This method improves implementation time accuracy and reduces delays. Keywords: Critical Chain Project Management, BIM, 3D Final planning system, High Rise Building, Contractor, Project execution time Proyek konstruksi high-rise building sering menghadapi tantangan dalam hal keterlambatan penyelesaian, yang berdampak pada penurunan kinerja kontraktor dan efektivitas waktu pelaksanaan proyek. Keterlambatan ini sering kali disebabkan oleh kurangnya efisiensi dalam penjadwalan proyek, yang secara umum bertujuan untuk meminimalkan waktu proses, waktu tunggu, dan tingkat persediaan, serta mengoptimalkan penggunaan fasilitas, tenaga kerja, dan peralatan. Dalam konteks ini, efektivitas proyek diukur melalui tiga kriteria utama: scope (ruang lingkup), time (waktu), dan cost (biaya). Penelitian ini menganalisa penerapan metote Critical Chain Project Management (CCPM), Bim 3D, Dan Last Planner System (LPS) pada Proyek High rise building. Pengolahan data metode ini menggunakan software SPSS 27 dan SEM-PLS 3.0. Faktorfaktor yang mempengaruhi adalah Critical Chain Project Management (CCPM) (X1), BIM 3D (X2), Last Planner System (LPS) (X3), kinerja kontraktor (Y1) dan waktu pelaksanaan (Y2). Analisa perencaan waktu menggunakan Microsoft project menghasilkan perencanaan awal 314 hari setelah menggunakan metode critical chain project management menjadi 235 hari atau 33,4 % optimasi waktu pelaksaannya. Hasil pengolahan data SPSS dengan metode CCPM, BIM, LPS secara Simultan didapatkan nilai signifikan yaitu 0,000 < 0,05, yang artinya berpengaruh terhadap kinerja kontraktor dan waktu pelaksaan proyek. Kemudian perencaan pelaksanaan dengan software BIM didapatkan progress visualisasi pelaksaan pekerjaan bangunan setiap lantai. Metode analisis Last planner system didapatkan Percent Plan Completed (PPC) sebesar 89.49%. Dengan penggunaan metode ini didapatkan Kata Kunci : Critical Chain Project Management, BIM 3D, Last planner system, High Rise Building, Kontraktor, Waktu pelaksanaan proyek
