The Impact

The article discusses the concepts of information modeling and 3D modeling. The relationship between the concepts of a BIM and a 3D model is analyzed and the key differences are identified. The advantages of using a federated information model when creating complex BIM designs of processing plants are presented and compared with working in a single file. A brief overview of the existing software systems that may be used to create information and 3D models of processing plants is presented. The example of an information model design for the backfill material production shop based on the tailings of the Tominsky GOK concentrator is used to illustrate the interaction between various software packages related to the development of the corresponding sections of the 3D model (TX for the production technology, AP for the architectural solutions, QL for the reinforced concrete structures). The design algorithm used in these software packages is considered and the corresponding structural calculations are provided. The benefits and effectiveness of the corresponding software packages are described. The impact on the calculation quality and reliability, the time required for the design work, referencing between various parts of the design, the ability to search for collisions and subsequently minimize errors in the construction and equipment installation are also analyzed.

Building Information Modeling (BIM), which is developed for improving the collaboration and interoperability in the construction sector has many dimensions. While “3D model” is developed to visualize the buildings, simulation-based “4D model” integrates 3D model with time and “5D model” is attained as a result of including cost in the 4D model. The purpose of this study is to define 5D modeling in detail and to assess the capacities of 4D/5D modeling software packages via comparison. To assess the capacities of 4D/5D modeling software packages, a test case was developed. A 3D model of a project was created in Autodesk Revit 2017 and 4D/5D models of the building were developed by using Autodesk Navisworks Manage 2017, Synchro Pro 2016.2 and Trimble Vico Office R6.0 software packages. In the test case, the stages and their durations when preparing 4D/5D models were identified and the advantages and disadvantages of each software package were determined. The results of the study could be used as a guide by the companies desiring to conduct 4D/5D application in the sector.

Construction Efficiency

Building Information Modeling (BIM) design becomes popular with the growing needs of enhancing construction efficiency. During the design process, 3D Modeling is the foundation of generating and analyzing building information. The modeling tool, Autodesk Revit, automatically creates log files, which can record all design activities. This paper investigates and analyzes the operation data from unstructured temporal Revit log files. These data were recorded when executing the general and external command to build a 3D model of a typical residential two-story building. The objectives of this analysis were to figure out the influence elements of producing a good framing model and to give some suggestions for improving modeling efficiency. In order to extract the useful specific commands, the information in the text journal file was transferred to an excel file, before reading by a data mining tool, RapidMiner. It generated a pie chart to show the repetition amount of modeling activities. Analyzing the reasons of repeating some commands frequently, this paper contributes the possibility to reduce the useless repetition for building a good 3D model.

The Impact

<p><strong>Abstract.</strong> The implementation of Building Information Modelling (BIM) in each project, which is planned, have a design and construction stages. In the construction stage the objects are modelled by architects, engineers, and surveyors. Modelling process allowed to construct a BIM, which replaces two-dimensional (2D) building information into a three-dimensional (3D). Noticed that 3D BIM created by surveyors is not the same as 3D BIM, which is created by architects. Therefore, the purpose of this study is to identify the differences of the created 2D draftings made by 3D models between surveyors and architect’s. The surveyors make their model by using Unnamed Aerial Vehicle (UAV) system: Airborne Drone Data and Data photogrammetric processing technology. The 3D models accuracy is assessed by UAV images processing. The 3D information should be used to calculate façade geometry, volume, distances, contours, which are in the shadowed side of the house, and create 2D façade draftings. Traditionally, architects used 2D building’s façade draftings for pre-design in Construction Projects (CP). 3D architectural model is created by using structural 2D draftings created with Autodesk software. The architectural 3D model is more convenient for the general design and the visual view, it is easily to evaluate the impact of the changes that will be made. The 3D architectural model helps to finish a project at a low cost and also to evaluate the effect of the changes made. The 3D model from surveys measurements shows real view of an object (with deformations), meanwhile the 3D model from architects is a corrected image. Discrepancies between surveyors and architect’s 2D models made by 3D virtual reality (VR) are analysed in this article.</p>

It is a common phenomenon that 3D model and 2D engineering drawings are widely used together in modern manufacturing scenario. Therefore it makes a lot of extra tasks to do for both of them which lead to such results as high time consuming, labor intensive during the process. The Model-based Definition (MBD) approach is definitely an effective method to solve above problems. To facility the usage of the MBD Technology, this paper introduces two kinds of MBD model (design-MBD, process-MBD), and describes their contents as well. The paper also focuses on constructing the dMBD model and pMBD model from two aspects: information organization and annotation standard so that these models can guide production more effective.

The new campus of ITB-Indonesia, which is located at Jatinangor, requires good facilities and infrastructures to supporting all of campus activities. Those can not be separated from procurement and maintenance activities. Technology for procurement and maintenance of facilities and infrastructures –based computer (information system)– has been known as Building Information Modeling (BIM). Nowadays, that technology is more affordable with some of free software that easy to use and tailored to user needs. BIM has some disadvantages and it requires other technologies to complete it, namely Geographic Information System (GIS). BIM and GIS require surveying data to visualized landscape and buildings on Jatinangor ITB campus. This paper presents the on-going of an internal service program conducted by the researcher, academic staff and students for the university. The program including 3D surveying to support the data requirements for 3D modeling of buildings in CityGML and Industry Foundation Classes (IFC) data model. The entire 3D surveying will produce point clouds that can be used to make 3D model. The 3D modeling is divided into low and high levels of detail modeling. The low levels model is stored in 3D CityGML database, and the high levels model including interiors is stored in BIM Server. 3D model can be used to visualized the building and site of Jatinangor ITB campus. For facility management of campus, an geo-information system is developed that can be used for planning, constructing, and maintaining Jatinangor ITB’s facilities and infrastructures. The system uses openMAINT, an open source solution for the Property &amp; Facility Management.

Purpose As the use of building information modeling (BIM) for facilities management (FM) continues to grow, questions remain around the quality and completeness of digital assets to support FM practices. This paper aims to examine the current gap between digital and physical assets in the absence of formal information requirements and its impact on the handover process. Design/methodology/approach An action-research was carried out with a large public organization to understand the challenges of their current FM processes and the steps required in developing an asset information model (AIM) from a project information model (PIM). A mixed method approach was employed with interviews, document analysis and an exploratory pilot case study. Findings This paper investigates the process, the challenges and the level of effort of the information commissioning process to create a fit-for-use AIM. Four distinct steps were identified in the process as follows: analyzing the handover PIM and documents, extracting FM-specific information, populating the model with the information and attaching operations and maintenance (O&M) documents. The research highlights the significant amount of effort that is required when no specific asset information requirements are formulated at the project onset. Practical implications The paper presents an information commissioning process that helps to develop an AIM from a PIM. Understanding the impact of the lack of requirements on the information commissioning process can help asset owners understand the importance of defining and articulating their information requirements up front. Originality/value This paper provides empirical evidence of the impact of the absence of formal information requirements on the development of a fit-for-use AIM.

Abstract. Nowadays, in light of the latest development in three-dimensional (3D) modeling technology, an essential role is given to the research and development of fully-automated or semi-automated processes in order to increase workflow effectiveness. A key challenge is thus to automate the process leading to the geometric model which supports the Building Information Modeling (BIM) or 3D-Geographical Information Systems (3D-GIS). This 3D model usually originates from image-based or range-based point clouds. This research is the beginning of the development of a 3D modeling approach that is semi-automatic, and possibly fully-automatic, by combining polygon surface fitting (polyfit) technique and monoscopic multi-image measurement system. With the advent of dense matching and Structure from Motion methods (SfM), point clouds can be generated from multiple images obtained from digital cameras. Then, to reduce the data and to allow for efficient processing, it is necessary to extract polygonal surface data from point clouds delivered by the dense matching process. The polygonal surface is then used for the basis of further manual monoscopic measurements which are achieved separately on each image to obtain more detailed 3D model. Next, this approach analyzed the polygonal surface deformations in comparison to the initial point cloud data. It can be seen how the resolution and noise of the original point clouds affect the subsequent Polyfit-based modeling and monoscopic measurements. The deformations and the accuracy evaluation have been undertaken using different open source software. Also, the geometric error in the polyfit-derived polyhedral reconstruction propagating to the subsequent monoscopic-derived measurements was evaluated. Finally, our modeling approach shows that it can improve the processing speed and level of detail of the 3D models achieved using existing monoscopic measurements. Typically geometric accuracy itself doesn’t have enough information to make accurate geometry model.

Project Data

As an emerging technological and procedural shift within the building design industry, Building Information Modeling (BIM) is a set of interacting processes and technologies to manage essential building design and project data in digital format throughout the design procedure. It is also a central data repository to store and recall different kinds of project information through creating a 3D model as well as providing intelligent data for this model. Besides, project documentation can be brought forward as a byproduct of the 3D model. This kind of BIM approach allows designers to finish their design work and have the documentation of a building simultaneously. As a result, this design approach can accelerate the design procedure of building project through less time and effort. This paper begins with an outlook on the mechanism that BIM approach how to increase the productivity rates and reduce the waste of resources in architecture industry. Then, it provides a project example on theuse of Autodesk Revit software system. At the end, a discussion on how BIM approach is applied to into the building design industry and on the potential benefits of BIM approach is put forward.
