This study is about a case of web application development using representative commercial BIM platform-linked APIs from Autodesk and Bentley Systems. The development method was aimed at application development using Autodesk's Forge API and Bentley System's iTwin API. The specific development content was limited to the Model Viewer, Issues, and File Transfer API, and the administrator's site. The first research result is that parts with different internal configurations of commercial platforms were independently modularized and developed, and the common front-end was unified. The second research result is that a web front-end technology, was used to visualize 3D models using the viewer API, and the possibility of additional application expansion was discovered.

In recent years, the mandatory use of BIM has been actively promoted due to the digital transformation of the construction industry. However, the CDE (Common Data Environment) system, which is an essential element for operating BIM, has not been established in accordance with the domestic situation. To solve this problem, this study analyzed the results of previous studies, including the ISO 19650 standard and domestic CDE system requirements, and developed BIM-based collaboration functions that are suitable for the domestic construction industry through functional analysis of domestic and foreign commercial CDE solutions. And we developed a BIM collaboration framework to provide BIM-based collaboration functions as a service by using cloud technologies such as IaaS, PaaS, and SaaS to provide infrastructure resources flexibly and flexibly. The BIM collaboration framework developed in this study meets most of the CDE requirements of ISO1965, so it can secure competitiveness when bidding for overseas BIM projects. Also, because the BIM collaboration functions can be selectively applied to build a BIM-based collaboration platform, it is expected that the utilization of the BIM collaboration framework will be high, as it can minimize not only the time to build the platform but also the operating costs, and the usability is higher than that of existing commercial BIM CDE solutions.

최근 건설데이터를 활용하는 BIM과 공간데이터를 활용하는 GIS 간의 통합 및 연계를 시도하려는 연구가 많이 이루어지고 있다. 하지만, BIM과 GIS의 데이터모델이 서로 너무 다른 특징을 가지고 있어 두 데이터모델 간의 통합을 통한 상호운용은 매우 어려운 실정이다. 따라서 본 연구에서는 BIM과 GIS의 효율적인 상호운용성을 시스템적으로 확보하기 위한 BIM과 GIS 상호운용 플랫폼을 설계하여 제시한다. 그리고 기존의 상용 소프트웨어들을 분석하여 본 연구에서 제안한 플랫폼에 필요한 요소기술과 기능들을 정의하여 제시한다.

Over the past several years, the building codes that govern commercial building construction have become increasingly prescriptive in nature, specifying detailed information related to the design and installation of the systems, while offering no reasoning behind their prescriptive measures. For example, metal stud framing is commonly used in commercial building construction to create bearing walls and non-bearing partition walls. BIM provides a powerful platform for developing and implementing "pre-planning" tools and methods to facilitate both engineering and administrative controls during construction. This paper discusses the use of BIM to enhance constructability for commercial building construction activities, specifically metal stud framing. Using specific real-world examples this paper demonstrates ways that BIM can be used to foresee potential construction issues and motivates and informs future uses of BIM technologies

Dweller's safety is one of the most important factors for the evaluation of building performance. The process of conventional safety design which is normally performed by the codes and designer's experiences is not enough to check the whole possibilities of unexpected accidents in the built environment. It means that the dwellers might be always exposed by the dangerous situation which should have been removed in the architectural design process. In order to solve this problem, this study intends to introduce a rule-based performance evaluation technology based on BIM(Building Information Modeling). The proposed technology focuses on the real time evaluation of dweller's safety in the ordinary life in the designed building alternatives and uses a commercial BIM tool as a design and evaluation platform.

본 연구는 건축설계 안에서 사물인터넷서비스를 시뮬레이션 하는 일종의 전문가 시스템을 개발하는 연구로서 건물정보를 활용하여 보다 향상된 기능의 시뮬레이션을 구현하는 것을 목표로 한다. 본 연구에서 소개되는 프로토타입 시스템(iotBIM)은 사용자의 행위와 사물인터넷서비스를 디자인 대안으로부터 자동으로 생성된 가상공간상에서 시뮬레이션 한다. iotBIM의 개발을 위하여 본 연구에서는 상용 건축정보모델링(BIM) 저작도구를 이용하였다. iotBIM의 개발을 위하여 건축정보모델링 플랫폼을 활용한 것은 BIM 설계과정에 이미 세밀한 3차원 모델이 생성되기 때문이다. 따라서 iotBIM은 BIM기반 플랫폼에 장착되어 디자인 대안에 대한 시뮬레이션 모듈로 활용된다. 건축 디자인 과정 중에서 건축가는 iotBIM을 실행시킬 수 있으며 이를 통하여 가상공간에서 이루어지는 시뮬레이션을 통하여 사물인터넷 서비스 상황을 눈으로 확인하고 디자인 의사결정을 할 수 있다. 본 연구는 기초적 성격의 연구로서 본 연구의 궁극적인 목표 달성을 위한 이론적 기술적 기반을 마련하기 위한 것이다.

Cost segregation helps reduce tax liabilities by reclassifying real property to personal property and accelerates tax depreciation of a property. A typical cost segregation study requires much time and high costs. This study proposed a BIM integrated cost segregation process that can be applied to any commercial building project. The proposed BIM-based cost segregation process was verified in a new commercial construction project. It approved that this approach can: (1) increase the cash flow for the owner and provide assistance to tax-paying enterprises; (2) enable the contractor to use it as an added value in the bidding process; (3) realize data sharing in a common platform to improve the cost segregation study efficiency and reduce costs and errors; (4) contribute to the asset management in the life cycle of buildings while filling in the blank of cost segregation process. Future studies will focus on the automation of cost segregation and asset management in building construction's life cycle.

Modern construction projects have stakeholders from various construction fields, highlighting the importance of efficient information sharing and collaboration. The expanding scope of Building Information Modeling (BIM), particularly in the domestic construction sector, necessitates a Common Data Environment (CDE). However, applying foreign commercial CDE solutions within the domestic context is challenging due to the difficulty of aligning them with the unique organizational structures and characteristics prevalent in the country. Furthermore, the information review and approval processes specified by ISO 19650 often fail to harmonize adequately with the domestic design procedures, limiting the full utilization of CDE advantages. This study endeavors to develop a Korean CDE collaborative platform based on ISO 19650, with a focus on adapting workflows and information container systems to the domestic context. Building upon the requirements of ISO 19650-based CDE workflows and information containers, this research involves an in-depth analysis of information generation, sharing, review, and approval processes within domestic design organizations, offering tailored CDE workflows and information container systems that align with the specific needs of the Korean construction industry.

Earthmoving operations account for approximately 25% of construction cost, generally executed prior to the construction of buildings and structures with heavy equipment. For the successful completion of earthwork projects, it is crucial to constantly monitor earthwork equipment (e.g., trucks), estimate productivity, and optimize the construction process and equipment on a construction site. Traditional methods however require time-consuming and painstaking tasks for the manual observations of the ongoing field operations. This study proposed the use of a GPS sensor embedded in a smartphone for the tracking and visualization of equipment locations, which are in turn used for the estimation and simulation of cycle times and production rates of ongoing earthwork. This approach is implemented into a digital platform enabling real-time data collection and simulation, particularly in a 2D (e.g., maps) or 3D (e.g., point clouds) virtual environment where the spatial and temporal flows of trucks are visualized. In the case study, the digital platform is applied for an earthmoving operation at the site development work of commercial factories. The results demonstrate that the production rates of various equipment usage scenarios (e.g., the different numbers of trucks) can be estimated through simulation, and then, the optimal number of tucks for the equipment fleet can be determined, thus supporting the practical potential of real-time sensing and simulation for onsite equipment management.
