Abstract
BIM (Building Information Modeling) is one of the technologies that is frequently used in the process of digitalizing the construction industry to collaborate and share information. Several advantages were excepted from the implications of BIM, especially in increasing profitability, efficiency of time and cost. Another benefit that can be concurred is the smooth process of communication within stakeholders to achieve the same goals.
The implication of BIM on construction projects has been run by PT ADHI KARYA (Persero) Tbk. since 2016 for the Gelora Bung Karno Stadium project. Hence, the implementation of BIM was adopted in the Project Building of Site Office, HSSE Office, and Laboratory RDMP RU V – Balikpapan, which consisted of 6 (six) main building developments. The objective of this research is to know the benefits of BIM using study literature methods for 3D, 4D and 5D modelling processes. The results found that using BIM in the construction industry contributes to communication among stakeholders and, generally, BIM implementation could increase the efficiency of both time, cost and quality of one project.
Keywords
Bim, Sholab1. Introduction
Along with the development of an increasingly fast industrial world, the 4.0 industrial revolution brought technological changes to time and cost efficiency, minimizing risks to work and being able to facilitate coordination between parties and speed up the work process. This industrial revolution also had an impact on the dynamic world of construction, adopting technology, especially used in aspects of planning, design, implementation, and maintenance.
In the Site Office, HSSE Office and Laboratory RDMP RU.V - Balikpapan Building Project, which was carried out by the implementing contractor, namely PT. Adhi Karya (Persero) Tbk. The Building Department is demanded by the management to implement BIM (Building Information Modeling) in the SHOLAB project during the construction period. While the implementation of BIM (Building Information Modeling) was first carried out by PT. Adhi Karya on the Gelora Bung Karno Stadium project (2016-2018). And in 2020, ADHI managed to become the first company to obtain ISO BIM 1965 from the British Standards Institution (BSI).
BIM (Building Information Modeling) has so far been used as a technology used in the process of digitizing contractor companies in Indonesia. In the Site Office, HSSE Office and Laboratory Building Project RDMP RU.V - Balikpapan consists of 6 main buildings with a total building area of 37,550 m2. This is related to the regulation issued by the Ministry of Public Works and Public Housing in attachment IV of the Minister of Public Works and Public Housing No. 22 of 2018, which reads that state buildings (BGN) with an area of over 2000 m2 and above two floors must apply BIM (Building Information Modeling) in the planning stage until construction. With these regulations, construction service companies are expected to use BIM technology in the construction implementation process (Nelson & Sari 2019).
BIM (Building Information Modeling) allows for new ways of working that promote cooperation and information sharing (Vilutienė et al., 2019). BIM (Building Information Modeling) has a variety of advantages, including increased profitability, cost efficiency, better time management, and stronger client connections (Azhar 2011) (Ding, L., Zhou, Y. and Akinci 2014). Furthermore, BIM (Building Information Modeling) enhances design quality by removing conflicts and predicting rework (doing the same thing over and over), as well as being an effective quality control tool (Chen & Leo, 2014)
By using BIM (Building Information Modeling) technology, it is expected to be able to shift conventional construction so that we do not find events that often occur, one of which is the occurrence of conflicts or misunderstandings between stakeholders due to unclear information flow and information that is not recorded properly, which can result in delays in training time which have an impact on cost overruns. In BIM (Building Information Modeling), stakeholders work together, exchange information, and collaborate to

streamline the modeling process so that they can evaluate projects before construction is carried out (PUPR 2018).
2. Literature Review
2.1. Definition of Building Information Modeling (BIM)
Building Information Modeling (BIM) is a process that begins with creating three dimensions in which it contains building information that can be used as a tool or means to make a plan or design, implementation of construction, and maintenance of the intended building for all parties involved in the building project, such as owners, consultants, and contractors, as well as subcontractors.
Building Information Modeling (BIM) according to ISO 19650 is a method to get better productivity and profit through more detailed specifications and deliver it with the right amount in the design, planning, construction, building and infrastructure management phases using the right technology. Meanwhile, the US National Building Information Model Standard Project Committee defines Building Information Modeling (BIM) as a digital representation of the physical and functional characteristics of a facility. Building Information Modeling (BIM) is a shared knowledge and information resource about a facility that forms a reliable basis for making decisions throughout its life cycle, defined as existing from the beginning of conception to disassembly.
2.2. Advantages of Building Information Modeling (BIM)
The benefits of Building Information Modeling (BIM) are as follows:
1. Buiding Information Modeling (BIM) has three-dimensional modeling so that communication can be more easily and clearly understood, even by ordinary people.
2. With Building Information Modeling (BIM), we can get the required volume of material, as well as cost estimates that are faster and more accurate because the data is released by the model we created.
3. Building Information Modeling (BIM) makes it easier for us to share or use data, because we use a single data to work together online (cloud), and it also makes it easier for us to access work both at the desk and in the field.
4. With Buiding Information Modeling (BIM), we can analyze the building in advance, such as the effect on the received load, wind, light, and heat, so that the building's performance is as expected.
5. We can always innovate to produce buildings that are more competitive without compromising on quality, because we can predict costs before the implementation of construction.
6. With a system of coordination and collaboration between parties related to the project, it will facilitate communication and make decisions so as to accelerate project implementation.
7. Buiding Information Modeling (BIM) at the beginning of the work can be used as a clash detection so that we can find out whether the 2D plan drawing that will be applied in the field clashes or not, especially between structural, architect, and MEP (mechanical, electrical, and plumbing) drawings.
2.3. Dimension of Building Information Modeling (BIM)
The shape of the object to be modeled consists of several types of dimensions in Building Information Modeling (BIM) are as follows:
1. D (Implementation Plan)
In the 2–D BIM model, everything is represented by a line and two dimensions require a width and a height.
Like a clearer cut image in 2D using the X axis and Y axis.
2. D (Share Information Model)
The addition of the Y axis to the 2D model makes the model 3-D. The 3D model is represented digitally from the existing design or condition. 3D elements and data used during the design and documentation stages.
3. D (Schedule Model)
In dimension 4 – D, this conveys information to all parties involved in the scope of work. The information conveyed is the implementation schedule (scheduling) quickly and effectively so that it can be known or seen how progress is made in the field from day to day.
4. D (Costing)
In this fifth dimension, which is added to the 4D model, is the cost, which previously obtained the volume first from the model so that we can enter the cost with the reference volume that we got. The 3D – BIM model has all the geometric information needed to determine the amount of material required. The 4D – BIM model has all the activities needed to complete a project. By entering a number of costs into the 4D BIM model and by assigning actual costs to materials, equipment, and labor (Eastman et al., 2011).
5. D (Sustainability)
Energy consumption analysis can be done with the help of the 6-D model. Accurate, precise, and complete results can be estimated before design.
37 6. D (Facility Management)
7. D BIM is used for maintenance and operation of the facility throughout the life cycle, which can be used to track data such as specifications, warranty data, component status, and others.
3. Methodology
The scope of work carried out in this BIM modeling is as follows (Figure 1.):
Figure 1 Flowchart
This research consists of 5 stages, including data input, 3D Model, 4D Model, 5D Model, and Evaluation.
4. Result and Analysis
The results and analysis describe the stages and output of BIM modeling that we used in the building projects of Site Office, HSSE Office, and Laboratory RDMP RU.V – Balikpapan.
4.1. 3D Modeling
3D Model refers to a 3D model of a building that already includes information parameters, more detailed components, and the ability to integrate and upgrade to the next dimension. The following is a 3D modeling flow using Revit Software (Figure 2.a)
4.2. 4D Modeling
4D modeling is a model that combines a 3D model with a work schedule that will produce an animation of a work sequence according to the implementation schedule. The previous implementation schedule was processed with Ms. software. Project, then integrated using Naviswork Software. The following is the flow of 4D modeling with Navisworok software (Figure 2.b).
For model checking, it can be checked by checking clash detection for scheduling, so that there are no sequential stages that are carried out concurrently and are in accordance with the predetermined implementation timeline, so that it appears that the visualization will be in accordance with the implementation timeline.

4.3. 5D Modeling
After confirming that there is no clash detection in the 3D modeling, the modeling can be used in a higher dimension, namely 5D Modeling. BIM 5D, also known as Quantity Take Off, performs volume calculations automatically, accurately, and quickly. The advantage of this 5D BIM is that the calculation will be more accurate because it uses a 3D model. In addition to the calculation of the reinforcement volume, it will automatically create a Bar Bending Schedule (BBS). The following is the flow of 5D Modeling using Revit Software (Figure 3.).

4.4. BIM Implemetation in SHOLAB Project Balikpapan
In the Project SHOLAB Balikpapan, the implementation of BIM is as follows (Figure 4.):
1. Approval Design/ Material
The use of BIM can facilitate the owner in the design/material approval process, because the owner can have a visual picture of the design submitted by the contractor.
2. Shop Drawing by Revit
Autodesk Revit can produce shop drawings, so drafters don't need to re-draw using Autocad to submit shop drawings.
39 3. 4D Simulation Scheduling
In the Project SHOLAB Balikpapan, the implementation of 4D Scheduling can facilitate owners to predict the progress of work based on a timeline schedule.
4. 5D Quantity Take Off
3D BIM Modeling can help Quantity Surveyors calculate the project volume progress, so the calculation for progress work can be faster and more accurate.
So, the use of BIM on the SHOLAB Project can produce work that is more effective and efficient, both in terms of time, cost and quality.
