Abstract
The construction industry is currently transforming toward digitalization to address the inaccuracies of conventional material volume calculations, which frequently trigger concrete waste and cost overruns. This study aims to analyze the effectiveness of 5D Building Information Modeling (BIM) implementation in improving quantity take-off (QTO) accuracy and optimizing the Cost Budget Plan (RAB) to reduce concrete waste in superstructure work. A case study was conducted on the Urbn-X Apartment Construction Project in Lippo Karawaci using Autodesk Revit 2024 and AutoCAD 2024 software. This study applied a comparative quantitative method by comparing volume and cost calculations among 2D-based conventional methods, Project Bill of Quantities (BQ) with a 2% flat waste assumption, and 5D BIM-based methods. The results show that 5D BIM modeling is capable of extracting real material quantities according to the actual building geometry, reducing the concrete volume from 7,247.46 m³ using the 2D QTO method to 7,158.16 m³ with the 5D BIM method. From a financial perspective, the budget using the 2D QTO method reached IDR 12,189,585,440.18, whereas the 5D BIM method resulted in a cost of IDR 12,038,868,297.97, yielding a budget efficiency of IDR 150,717,142.20 or 1.24%. The study concludes that applying a blanket 2% waste coefficient assumption in conventional methods leads to cost estimate overruns (over-budgeting), while quantity automation in 5D BIM proves to be more precise, transparent, and effective in minimizing concrete waste to safeguard project profit margins.

Industri konstruksi saat ini tengah bertransformasi menuju digitalisasi untuk mengatasi ketidakakuratan perhitungan volume material konvensional yang sering memicu timbulnya sisa material (waste) beton dan pembengkakan biaya. Penelitian ini bertujuan untuk menganalisis efektivitas implementasi Building Information Modeling (BIM) 5D dalam meningkatkan akurasi quantity take-off (QTO) dan mengoptimalkan Rencana Anggaran Biaya (RAB) guna mereduksi waste beton pada pekerjaan struktur atas. Studi kasus dilakukan pada Proyek Pembangunan Urbn�X Apartment Lippo Karawaci menggunakan perangkat lunak Autodesk Revit 2024 dan AutoCAD 2024. Penelitian ini menerapkan metode kuantitatif komparatif dengan membandingkan perhitungan volume dan biaya antara metode konvensional berbasis 2D, BQ Proyek dengan waste flat 2%, dan metode berbasis BIM 5D. Hasil penelitian menunjukkan bahwa pemodelan BIM 5D mampu mengekstraksi kuantitas material secara riil sesuai geometri aktual bangunan dan mereduksi volume beton dari 7.247,46 m³ pada metode QTO 2D menjadi 7.158,16 m³ pada metode BIM 5D. Dari aspek finansial, anggaran dengan metode QTO 2D mencapai Rp12.189.585.440,18, sedangkan metode BIM 5D menghasilkan biaya sebesar Rp12.038.868.297,97, memberikan efisiensi anggaran sebesar Rp150.717.142,20 atau 1,24%. Kesimpulan penelitian mengonfirmasi bahwa penerapan asumsi koefisien waste 2% secara menyeluruh pada metode konvensional memicu pembengkakan estimasi biaya (over-budgeting), sedangkan otomatisasi kuantitas pada BIM 5D terbukti lebih presisi, transparan, serta efektif dalam menekan waste beton demi menjaga margin keuntungan proyek.
