“…and Table 6. The percentage difference in the estimated volume of steel rebar between the conventional estimation method and the BIM-based estimation method is determined using the following equation processed from Anindya and Gondokusumo (2020). In Equation 1., the total volume 1 refers to the largest volume between the conventional estimation method and the BIM-based method, while the total volume 2 refers to the smaller one between the two estimation methods:…”

One of the construction materials with a high level of demand is steel rebar. Globally, the demand for steel rebar has quadrupled from 1960 to 2005—and this increase is predicted to double by 2050. In one project, steel rebar accounts for 16% to 60% of the total project budget. Therefore, if the volume of steel rebar is not estimated correctly it will have an impact on project budget wastage and swelling. The project budget wastage is indicated by the large volume of material remaining, while the budget swelling is indicated by the procurement of additional steel rebar because the material requirement is greater than the initial estimate. To minimize this, a comprehensive understanding of volume estimation is required. Currently, the method of estimating the reinforcement volume that is widely used is the conventional estimation method and the BIM (Building Information Modeling)-based estimation method. The conventional method is done manually based on the BBS (Bar Bending Schedule) as a reference. Meanwhile, the BIM-based method used in this study is the Allplan Engineering 2021 software and is a more modern estimation alternative because it is considered more practical, fast and efficient. Although these two methods are widely used, there are limitations and advantages that are taken into consideration when choosing the most appropriate method. Therefore, a study is needed to prove and compare the accuracy of the estimation of reinforcement volume between the conventional method and the BIM-based method. This study also highlights the advantages and limitations of the two methods for comparison. The conventional method is more transparent in terms of the estimation formula used because it is done manually. This can help the estimator track the estimation process to ensure the accuracy of the results. Whereas, the BIM-based estimation method is superior in terms of work automation and accuracy compared to the conventional method. Furthermore, the limitations of the conventional method are that it does not have a 3D visual model and requires a relatively long time to complete if there is a revision of the plan drawing. On the other hand, the BIM-based estimation method offers convenience in the form of data input using 3D drawings. The practical data input process is proven to provide accurate results. However, the main limitation of the BIM-based method, especially for the software used in this study, is that the estimation formula cannot be traced because it relies more on three-dimensional modeling. This causes the estimator to be unable to ensure the accuracy of the estimation results. However, this limitation may differ from other BIM software products outside of this study.

“…Kegiatan terdiri dari sosialisasi gambaran umum BIM khususnya BIM 5D, pentingnya penggunaan BIM 5D, manfaat, dan efisiensi penggunaan BIM 5D dengan salah satu jenis BIM 5D yakni Cubicost. Cubicost adalah salah satu dari beberapa jenis perangkat lunak yang menjadi bagian dari Building Information Modelling (BIM) berdimensi 5D yang memiliki keunggulan untuk melakukan pekerjaan quantity take off (Anindya & Gondokusumo, 2020). Kegiatan ini juga diikuti dengan pelatihan Cubicost BIM 5D untuk 3 tupoksi yang dimiliki Cubicost yaitu Takeoff for Architecture and Structure (TAS) untuk perhitungan elemen arsitektur dan struktur, Takeoff for Rebar (TRB) untuk perhitungan elemen pembesian, dan Tender Series for Bill of Quantity (TBQ) untuk perhitungan rancangan anggaran biaya pada proyek (PUPR, 2019).…”

Permintaan mengenai kebutuhan pada bidang konstruksi terus meningkat tiap waktunya. Banyaknya Perusahaan yang bergerak pada bidang konstruksi bersaing untuk memberikan pembangunan yang terbaik pada clien-nya. Namun pada kenyataan, setiap proyek yang berlangsung tidak selalu berjalan mulus. Banyak sekali terjadi humans erorrs selama proses konstruksi berlangsung. Hal tersebut bisa saja terjadi karena pihak penyedia jasa masih mengandalkan metode- metode konvensial pada kegiatan konstruksi dan belum menerapkan digitalisasi. Digitalisasi ini merupakan bentuk kepedulian terhadap dunia konstruksi di Indonesia, khususnya area Solo raya. Untuk mencapai hal tersebut, maka dilakukanlah pengabdian yang bertujuan untuk memberdayakan penyedia jasa untuk melakukan digitalisasi pada kegiatan konstruksi melalui penerapan BIM. Penyedia jasa yang digandeng merupakan penyedia jasa lokal yakni, CV Batu Intan. Pengabdian ini berisikan kegiatan sosialisasi dan pelatihan penggunaan BIM 5D. BIM 5D dipilih karena BIM 5D dapat menentukan volume material serta biaya secara akurat. Hal tersebut tentu sangatlah membantu selama kegiatan konstruksi berlangsung. Metode yang digunakan pada pengabdian ini adalah perencanaan, sosialisasi dan pelatihan (short course), serta peninjauan dan monitoring evaluasi. Kegiatan pengabdian ini memberikan hasil yang baik pada penyedia CV. Batu Intan dalam penggunaannya terhadap BIM menjadi lebih paham dari yang sebelumnya masih awam mengenai BIM. The demand for needs in the construction sector continues to increase. Many companies operating in the construction industry compete to offer the best construction to their clients. However, in reality, every project that is carried out does not always go smoothly. Many human errors occur during the construction process. This could happen because service providers still rely on conventional methods in construction activities and have not implemented digitalization. This digitalization is a form of concern for the world of construction in Indonesia, particularly in the greater Solo region. To achieve this, a service has been produced which aims to enable service providers to digitize construction activities through the application of BIM. The partner service provider is a local service provider, namely CV Batu Intan. This service contains socialization and training activities in the use of 5D BIM. BIM 5D was chosen because BIM 5D can accurately determine material volumes and costs. This is definitely very useful during construction activities. The methods used in this service are planning, socialization and training (short courses), as well as evaluation, monitoring and follow-up. This service activity gives good results to CV providers. Batu Intan, in his use of BIM, has become more proficient than he was before.

<p>Building Information Modelling (BIM) is a system for digitizing data processing that can help work in the construction industry run more effectively and efficiently. One type of BIM is 5D BIM. 5D BIM has the function of determining the take-off quantities and analyzing the costs of a building. An example of 5D BIM is Cubicost. Cubicost BIM is a BIM from the Glodon company that allows you to calculate work volumes in a detailed and precise way. In this research, the case study presented is an architectural work on the Waras Wiris Boyolali Hospital Emergency Building Construction Project. The architectural section was selected because architectural works play an important role in nominal terms, so the determination of volume greatly influences construction costs. This research uses Cubicost TAS and TRB software. Cubicost Software's volume results have also been validated so that they show a 99% correlation figure with volume obtained from conventional calculations. Based on the research carried out, the cost of using Cubicost software for architectural works in the Waras Wiris Boyolali Emergency Hospital Building Construction Project is Rp. 1.695.645.165,47. Using the Cubicost software also produces an efficiency of 11.550% on RAB from the consultant.</p>
