"Manfaat paling signifikan dari BIM 4D adalah visualisasi pekerjaan konstruksi yang lebih baik, komunikasi yang lebih baik antara tim proyek dan meningkatkan kinerja waktu dan biaya proyek. BIM 4D memungkinkan pemangku kepentingan untuk memvisualisasikan kegiatan konstruksi selama siklus proyek EPC dan mengidentifikasi potensi konflik spasial dan konflik jadwal. Meskipun penelitian yang berkaitan dengan BIM 4D telah membuktikan manfaat pemodelan 4D dalam proyek konstruksi, manfaat ini masih dipertanyakan untuk proyek EPC, apakah dapat mengkompensasi biaya awal dan upaya untuk membuat model 4D. Strategi implementasi di seluruh siklus proyek EPC juga menjadi hal yang perlu diperhatikan agar implementasi BIM 4D dapat dilakukan dengan tepat. Melalui studi literatur dan wawancara terstruktur, penelitian ini mengidentifikasi kebutuhan sumber daya yang terdiri dari perangkat lunak, subkontraktor tambahan untuk melakukan survei 3D dan manhour yang dibutuhkan untuk melakukan implementasi. Selain itu strategi implementasi BIM 4D harus disesuaikan antara kesiapan model 3D dan jadwal proyek baik pada tahap inisiasi, prakonstruksi maupun Konstruksi. Hasil penelitian menunjukkan bahwa manfaat BIM 4D dinilai paling tinggi dalam meningkatkan kinerja produktivitas Konstruksi dan manajemen jadwal proyek EPC.......The most significant benefits of 4D BIM are better visualization of construction work, better communication between project teams and improving project time and cost performance. 4D BIM allows stakeholders to visualize construction activities during project duration and identify potential spatial conflicts and schedule conflicts. Although researches related to 4D BIM has proven the benefits of 4D modeling in construction projects, these benefits are still questionable for EPC projects, whether it can compensate the initial costs and efforts to create the 4D model. Implementation strategies throughout the EPC project lifecycle also need to be considered so that the implementation of BIM 4D can be carried out appropriately. Through literature studies and structured interviews, this research identifies the need for resources consisting of software, additional subcontractors to conduct 3D surveys and manhour needed to carry out the implementation. In addition, the BIM 4D implementation strategy must be adjusted between the readiness of the 3D model and the project schedule at the initiation, pre-construction and construction stages. The research results showed that the benefits of BIM 4D were rated the highest in improving Construction productivity performance and EPC project schedule management."

"Sebagian besar pekerjaan konstruksi dilakukan oleh kontraktor yang dipilih melalui sistema lelang, terutama dengan sistema harga terenda. Dengan pertimbangan harga terendah sebagai pemenang lelang pada proyek pemerintah sehingga membuat peserta lelang tidak merencanakan biaya K3 dengan baik. Hal tersebut tentu berpengaruh terhadap penerapan SMK3 di dalam proyekPenelitian ini fokus pada analisa hubungan lokasi bangunan, ketinggian bangunan dan work breakdown structure terhadap biaya K3 umum dan khusus serta meninjau lebih jauh faktor-faktor dalam variabel-variabel tersebut yang menjadi pengaruh dominan terhadap biaya K3 umum dan khusus. Tujuan Penelitian ini menganalisa faktor di dalam masing-masing variabel yang berpengaruh dominan terhadap biaya K3 umum dan khusus serta menganalisa hubungan antar variabel lokasi, ketinggian bangunan dan wbs terhadap model biaya K3 pada proyek konstruksi rusunawa dengan menggunakan Structural Equation Model-Partial Least Square (SEM-PLS). Hasil penelitian menunjukkan 8 hubungan signifikan dan 1 hubungan tidak signfikan antara variabel lokasi proyek, ketinggian bangunan, WBS dan biaya umum K3 sert biaya khsuus K3 dengan 6 hubungan signifikan terhadap biaya K3 umum dan khusus.......Most of the construction work is carried out by contractors selected through an auction system, especially with a fixed price system. With the consideration of the lowest price as the winner of the auction on a government project, it makes the bidders not plan their OHS costs well. This certainly affects the application of OHS in the project. This research focuses on analyzing the relationship of building locations, building heights and work breakdown structures to general and special OHS costs and further reviewing the factors in these variables that become the dominant influence on general OHS costs. and specifically. The purpose of this study is to analyze the factors in each variable that have a dominant influence on general and specific OHS costs and to analyze the relationship between location variables, building height and wbs to the OHS cost model in low-cost housing construction projects using Structural Equation Model-Partial Least Square (SEM)-PLS). The results showed 8 significant relationships and 1 insignificant relationship between project location, building height, WBS and OHS general costs and OHS special costs with 6 significant relationships to general and specific OHS costs."
