Abstract
Estimasi volume dan biaya merupakan aspek penting dalam manajemen proyek konstruksi karena menjadi dasar penyusunan anggaran. Metode konvensional yang berbasis perhitungan manual dari gambar dua dimensi masih umum digunakan, tetapi rentan terhadap kesalahan interpretasi gambar dan kurang efisien dalam pengolahan data. Perkembangan teknologi Building Information Modeling (BIM) memungkinkan proses Quantity Take-Off (QTO) dan estimasi biaya dilakukan secara lebih sistematis dan akurat melalui model digital tiga dimensi. Penelitian ini menganalisis penerapan BIM 5D pada perhitungan volume dan estimasi biaya struktur bored pile (Ø914,2 mm dan Ø711,2 mm) dan pile cap (PC.1, PC.1A, PC.2, PC.2A, PC.2B, dan PC.3) pada Proyek Dermaga II Section Ujung Pelabuhan Probolinggo Baru. Pemodelan 3D dan QTO volume beton menggunakan Software Cubicost TAS, QTO berat baja tulangan menggunakan Software Cubicost TRB, dan estimasi biaya menggunakan Software Cubicost TBQ. Data yang digunakan berupa shop drawing AutoCAD pada kedua metode, dengan acuan harga dari Harga Satuan Pokok Kegiatan (HSPK) Kota Probolinggo Tahun 2023. Perbandingan dilakukan melalui analisis selisih volume beton, berat baja tulangan, dan estimasi biaya antara metode konvensional dan BIM. Hasil penelitian menunjukkan metode BIM secara konsisten menghasilkan kuantitas yang lebih kecil pada seluruh elemen. Volume beton metode konvensional sebesar 528 m³ dan metode BIM 517,143 m³ (selisih 10,857 m³), sedangkan berat tulangan metode konvensional 74.481 kg dan metode BIM 74.230,91 kg (selisih 250,09 kg). Selisih terkecil terdapat pada elemen bored pile. Total estimasi biaya material metode konvensional sebesar Rp 2.094.015.000 dan metode BIM Rp 2.070.202.250, sehingga metode BIM lebih rendah sebesar Rp 23.812.750 (−1,14%). Elemen bored pile Ø914,2 mm memiliki kontribusi biaya terbesar (22,7% dari total biaya), sedangkan selisih biaya terbesar antara kedua metode terdapat pada elemen pile cap PC.2A sebesar −Rp 4.713.365.

Volume and cost estimation are critical aspects of construction project management, as they form the basis for budget preparation. The conventional approach, which relies on manual calculation from two-dimensional drawings, remains widely used but is prone to drawing-interpretation errors and offers limited efficiency in data processing. Building Information Modeling (BIM) addresses these limitations by enabling Quantity Take-Off (QTO) and cost estimation to be carried out more systematically and accurately through three-dimensional digital models. This study examines the application of BIM 5D to the volume and cost estimation of bored pile (Ø914.2 mm and Ø711.2 mm) and pile cap (PC.1, PC.1A, PC.2, PC.2A, PC.2B, and PC.3) structures at Jetty II, Ujung Section, Probolinggo New Port. Cubicost TAS was used for 3D modeling and concrete-volume QTO, Cubicost TRB for reinforcement-weight QTO, and Cubicost TBQ for cost estimation. Both methods derived their quantities from the same AutoCAD shop drawings, with unit prices based on the 2023 Unit Price Schedule (HSPK) of Probolinggo City. The two methods were then compared by analyzing the differences in concrete volume, reinforcement weight, and estimated cost. The results show that BIM consistently produced smaller quantities than the conventional method across all elements. Concrete volume reached 528 m³ under the conventional method and 517.143 m³ under BIM, a difference of 10.857 m³, while reinforcement weight totaled 74,481 kg conventionally and 74,230.91 kg under BIM, a difference of 250.09 kg; the smallest gap occurred in the bored pile elements. The total material cost was estimated at Rp 2,094,015,000 for the conventional method and Rp 2,070,202,250 for BIM, making the BIM estimate lower by Rp 23,812,750 (−1.14%). The bored pile Ø914.2 mm element accounted for the largest share of cost (22.7% of the total), whereas the largest cost difference between the two methods occurred in the pile cap PC.2A element, at −Rp 4,713,365.
