Abstract

Construction 4.0 technology is an anticipation of the challenges of quality improvement in the construction industry. However, its implementation has not been simultaneous with an evaluation of the benefits and value of investment. For this reason, this research evaluates the benefits and investment feasibility of construction 4.0 technology on 36 projects of the Indonesian construction state-owned enterprise (SOE), PT. XYZ Persero Tbk. during 2020-2022 for Drones, Building Information Modeling (BIM) and Virtual Reality (VR) as individually and integrated. Based on evaluation data on the use of technology and financial data from technology investments obtained, this research quantitatively calculates the value of the benefits of increasing productivity and then calculates the financial evaluation using the Return on Investment (ROI), Net Present Value (NPV), Internal Rate of Return (IRR) and Benefit-Cost Ratio (BCR) methods and implies those results qualitatively. As a result, individually, BIM is the technology that contributes the most in terms of benefits, VR contributes well in terms of investment value, while drones still have development potential. Integration between technologies is still challenging where the use of technology simultaneously does not guarantee significant integration between the three technologies reviewed in this research.

Abstract

Produktivitas operasi masih menjadi tantangan sektor konstruksi. Keterbatasan ruang dan metode konstruksi turut mempengaruhi hal tersebut. Kondisi ini dialami oleh Universitas Pasundan dalam pembangunan gedung baru. Lokasi yang sempit dan padat mempengaruhi pembangunan gedung tersebut. Untuk itu, penelitian ini melakukan evaluasi produktivitas secara khusus pada operasi pemasangan balok baja berdasarkan data Time Studies, Method Productivity Delay Model (MPDM), Work Sampling dan 5 Minutes Rating. Analisis produktivitas dilakukan dengan menggunakan Method Productivity Delay Model (MPDM), Cycle Chart, Process Chart dan Crew Balance Chart. Hasilnya, evaluasi produktivitas keseluruhan operasi pemasangan balok baja menunjukkan perbandingan presentase pelaksanaan pekerjaan dibanding delay sebesar 62% berbanding 38%. Hasil ini cukup baik mengingat jangkauan proporsi produktivitas pekerja konstruksi berada pada rentang 40-70% dibandingkan dengan 62% pada proyek ini. Peningkatan produktivitas masih dapat dilakukan dengan mencegah delay akibat peralatan; efisiensi jumlah pekerja khususnya peladen; serta optimalisasi durasi masing-masing tugas dengan mengacu pada durasi terbaik yang diperoleh dari hasil pengamatan. Dengan demikian, nilai produktivitas pemasangan tiap batang balok baja dapat meningkat dari 10,36 menit/unit menjadi 6,25 menit/unit. Hasil ini diharapkan dapat menarik penelitian-penelitian serupa dengan objek perhitungan produktivitas yang berbeda untuk menghasilkan data produktivitas operasi konstruksi di Indonesia dan mendorong peningkatan produktivitas di sektor konstruksi.

Abstract

Structural building components such as columns, beam and slab require formwork in its construction. Formwork plays an important role in forming the dimensions of the structure to fulfill the design. This study aims to determine the formwork comparison between conventional and aluminum in terms of characteristics, implementation methods and costs. This study compares the characteristics, implementation methods and costs using quantitative and comparative methods. Data on aluminum and conventional formwork were obtained by observing the project site implementation and studying the literature. In the construction of project mall X building, several types of formwork were used, including semi-system formwork (semi peri) and aluminum formwork used for columns and conventional formwork used for beams. That consideration is needed to determine the most efficient formwork in terms of characteristics, method of implementation and costs. The result shows that in project mall X building, aluminum formwork has the same cost as conventional formwork but the process is faster and more efficient than conventional formwork. In addition, aluminum formwork does not produce wood waste and can be reused for 150-200 installation. after the researchers analyzed the installation of the formwork system in the mall X construction project. For the development of further research, it is suggested to make a comparison of project X with other projects, besides that it also makes a comparison of the types of formwork with several variables so that it can consider the use of the type of formwork in terms of construction needs.

Abstract

Productivity in Building Information Modeling (BIM) modeling plays a key role in project efficiency. However, the comparison between precast and traditional methods is still rarely studied. This research investigates the productivity comparison between BIM modeling methods and traditional construction execution on the Rumah Sakit Mitra Pumbon Subang project. The study uses a descriptive quantitative approach with data collected through 3D modeling (Autodesk Revit), scheduling (Microsoft Project), and 4D simulation (Autodesk Navisworks). The results show that BIM modeling requires more time (28 days) compared to the precast method (41 days) due to design complexity and more detailed object modeling in Revit compared to traditional CAD drawings. Meanwhile, the traditional construction method takes longer (153 days) compared to the precast method (137 days), due to the standardization advantages of precast work. In terms of material needs, BIM provides more precise calculations using the "Duplicate with Full Properties" and "Rebar Template Library" features in Revit. In conclusion, BIM modeling takes longer, but offers better precision and physical efficiency. This research emphasizes the importance of selecting the appropriate modeling method for optimal construction performance.

Abstract

Construction design changes are a challenge that requires quick adjustments in project documents, especially in the Bill of Quantity (BoQ). These adjustments reflect major changes in costs and material requirements. The use of digital technology is key to facilitating this process, enabling faster and more accurate revisions. This research aims to compare volume calculations using Revit and manual volume calculations resulting from design changes in the YOGYA Kota Baru Parahyangan Development Project. In the process, the volume of material required for various construction elements is calculated manually and with the help of digital technology. The results of these two methods were then compared to determine significant differences and evaluate each method's efficiency and accuracy. This results show that the volume difference in profile steel profiles is +47.78%; concrete +21.83%; piles +12.06%; and reinforcement +2.00%. These findings show that Revit provides more accurate and detailed results than manual calculations, which are often prone to human error. Using Revit can speed up the design adjustment process, reduce costs and project completion time. This research contributes by providing empirical evidence of the benefits of digital technology in construction and practical guidance for professionals in choosing the right calculation method.
