Pemanfaatan teknologi BIM semakin banyak digunakan pada berbagai bidang salah satunya bidang industri konstruksi. Teknologi BIM dinilai mampu membantu menyelesaikan permasalahan selama pelaksanaan proyek konstruksi. Penelitian dilaksanakan pada proyek Gedung Administrasi dan Perkuliahan Universitas Pembangunan Jaya. Tujuan penelitian untuk mengetahui nilai perhitungan kebutuhan material struktur, nilai perbandingan perhitungan kebutuhan material struktur dan dampak serta penyebab perbedaan perhitungan pada metode konvensional dan Autodesk Revit. Penelitian dilakukan dengan menganalisis kebutuhan material struktur dengan metode konvensional melalui microsoft excel dan pemodelan pada Autodesk Revit. Adapun hasil perbandingan perhitungan volume beton dengan metode konvensional dan Autodesk revit pada struktur kolom, balok dan pelat secara berturut – turut yaitu 2,427 %, 1,103 % dan 0,402 %. Hasil perbandingan perhitungan berat besi dengan metode konvensional dan Autodesk Revit secara berturut – turut yaitu 0,002 %, 0,011 % dan 19,806 %. Perhitungan yang dilakukan pada material besi antara kedua metode tersebut dinilai sama karena nilai selisih perbedaan tergolong kecil yaitu dibawah 1 % kecuali pada struktur pelat karena keterbatasan license software yang digunakan peneliti. Perbedaan perhitungan volume beton antara metode konvensional dengan Autodesk Revit terjadi karena volume beton yang terhitung pada Autodesk Revit merupakan volume bersih dari beton yang sudah terkurangi dengan volume besi tulangan yang ada pada struktur tersebut.

The utilization of BIM technology is increasingly widespread in various fields, one of which is the construction industry. BIM technology is considered capable of helping to solve problems during the implementation of construction projects. The research was conducted on the Administrative and Lecture Building project at Universitas Pembangunan Jaya. The objective of the research is to determine the structural material requirements, compare the structural material calculation values, and analyze the impact and causes of differences between conventional methods and Autodesk Revit. The research was carried out by analyzing the structural material needs using conventional methods through Microsoft Excel and modeling in Autodesk Revit. The comparison results of concrete volume calculations using conventional methods and Autodesk Revit for columns, beams, and slabs are 2.427%, 1.103%, and 0.402%, respectively. The comparison results for steel weight using conventional methods and Autodesk Revit are 0.002%, 0.011%, and 19.806%, respectively. The steel material calculations between the two methods are considered similar because the difference is small, under 1%, except for the slab structure due to limitations in the software license used by the researcher. The difference in concrete volume calculation between the conventional method and Autodesk Revit occurs because the concrete volume calculated in Autodesk Revit is the net volume of concrete, which has been reduced by the volume of the reinforcement within the structure.
