도입까지 시간이 걸릴 것이라고 예측됐던 건설정보모델링(BIM : Building Information Modeling, 이하 BIM)이 어느새 성큼 다양한 분야에 진입했다. 영국, 싱가포르, 미국 등 해외에서는 이미 공공사업 시 BIM을 적극적으로 활용하고 있다. 우리나라 또한 2018년 국토교통부에서 '스마트 건설기술 로드맵'을 마련한 후 공공사업에 BIM을 단계적으로 도입해왔다. 대부분의 발주기관들은 오는 2025년까지 공공사업에 BIM을 전면 도입한다는 계획이다. 성균관대학교 공과대학 건설환경공학부 및 미래도시융합공학과 교수이자 국제건설자동화학회의 종신 상임이사인 권순욱 교수는 '스마트 건설 관리' 연구자이자 국내외에서 활동 중인 CM, BIM의 권위자다. 관련 분야의 책 8권과 100편 이상의 논문을 집필하고 30여 개의 특허·소프트웨어 등록을 보유하고 있다. 텍사스 오스틴 대학교 토목공학 박사 출신으로, 삼성물산, 한국건설기술연구원 등 일반 기업과 국가기관에서 실무와 이론을 두루 경험하며 경력을 쌓았다. 건설연구개발사업, 첨단 융복합 건설기술 등 다수의 국가 건설 R&D에 참여해 초고층 자재, 안전 모니터링, BIM 프로세스 표준개발 등의 시스템을 개발하기도 했다. 해외 연구자들과의 교류에도 적극적이다. 세계 석학들과 '노령 공학' 관련 영문교과서를 공동 집필(스마트주택 챕터 담당)했고, 2016년과 2019년엔 국제건설자동화학회와 국제프로젝트관리학회의 연사 자격으로 강단에 섰다. "영국, 싱가포르 등에선 공공사업을 100% BIM으로 발주하기 시작했습니다. 우리나라 정부도 비슷한 길을 가고 있습니다. 일정 규모의 발주 물량이 안정적으로 나오는 공공기관에서 그렇게 한다는 것은 국가가 전체 패러다임을 바꾸겠다는 의지 아닐까요?" 6월 10일 그의 연구실에서 권순욱 교수를 만나 BIM의 현황과 전망에 대해 들어봤다.

This study deals with the BIM (Building Information Modeling)-based energy performance analysis implemented in EnergyPlus. The BIM model constructed at Revit is updated at Design Builder, adding HVAC models and converted compatibly with the EnergyPlus. We can obtain the input values about HVAC system and building environment such as HVAC system efficient, the number of air changes and energy consumption of equipment on applying GAs (Genetic algorithms). After modification about HVAC system, Optimization about HVAC system energy consumption can be analyzed. In order to maximize the building energy performance, a genetic algorithm (GA)-based optimization technique is applied to the modified HVAC models. Throughout the proposed building energy simulation, finally, the best optimized HVAC control schedule for the target building can be obtained in the form of "supply air temperature schedule". Throughout the supply air temperature schedule is applied to energy performance simulation, we obtained energy saving effect result on simulation.

Recently, BIM (Building Information Modeling) technique is being considered as a critical delivery condition for the public projects according to the increase of best practices by practical application of BIM. However, since existing BIM studies are focused on the design and construction phases, those results are not considering the life cycle of a construction project. Therefore, this study suggests an integrated BIM operation process that enables an application of BIM for each phase of a construction project from planning to maintenance phases and develops an integrated BIM system based on the suggested methodologies. This study developed basic BIM functions and its application process by analyzing information systems in each project phase for a bridge construction project. Besides, this study performed case study and survey analysis for construction managers to verify a practical applicability of the developed system. Therefore, it is expected that the integrated BIM system is going to be utilized as a 3D-based integrated information management system considering life cycle of construction projects.

As major public owner agencies in Korea have improved the application level of BIM, many design and construction companies are paying more attention to ways to improve actual work productivity in the BIM execution process. In this study, we introduce a method to automate the placement of BIM libraries, a recurring task in the BIM-based design process that serves as a prime example of BIM design automation methodologies. In particular, we classify the target surfaces for placement of BIM libraries into straight lines, curves, vertical planes, and surfaces. For each target surface, we implement a BIM library automatic placement model in Dynamo, considering the spacing and alignment according to the distance between the centers of two objects and the linear length. The results of case studies confirm that the proposed method can be employed according to various placement environments and conditions with the working time shortened. The study proposes that various objects and structures that need to be placed according to the terrain characteristics can be placed accurately, and work productivity can be significantly improved through the automation of placement.

Railway is compsed in various components, such as subgrade, track bed, sleeper, rail, and overhead line, on a linear space. Therefore, comprehensive work for various design standards and guidelines is required when designing a railway facility. For this reason, much time and effort are required to review the relevant design standards and guidelines. While, automatic legal check system for BIM models has been developed in the architectural engineering, it has not been developed in the railway engineering. This study reviews the korean design standard and the korean code for railway engineering, and suggests some rule items of logical information. Comparing the suggested rule items to the railway BIM library, items of logical information and additional attribute information are obtained. The analysis results of railway design standards and BIM library presented in this study would be utilized for defining rule-set items that is essential for development of the automatic legal check system for railway BIM models.

Although there have been a lot of BIM R&Ds in the civil engineering and their applications to the real projects, BIM in the field is still known to be behind the other areas. One of the reasons for this should be that the civil projects is generally too public for private participants to try new technologies, but it is mainly because the projects are so huge and complex that we still have the working environment where the systematic information sharing or exchanging is not smooth enough. In this paper, we are verifying the possibility and proposing the direction of BIM information standardization technology in civil engineering based on the integrated BIM information standard framework. For this purpose, after reviewing the introduction plan for BIM information framework, we applied it to an actual civil structure for test. The implementation result proved that the framework has possibility and effectiveness for the takeoff and construction cost calculation, which confirmed the standard framework needs to be extended consistently. This study is expected to contribute to the standard system establishment and its technology propagation for BIM development in the civil engineering.

The BIM called information modeling is used by tool not only it will simply be appearing the image and can save the information. Recently, there is a lot of case that improves the construction productivity by using the BIM during the life cycle of bridge from order to management. Although we already recognize the advantage of BIM, it is a careful phase to use the BIM. Therefore, We made the BIM for bridge, evaluated the possibility that can build the object used in the civil engineer, studied about the utility, the improvement in order to use the BIM properly. As a result, the BIM can recycle the information by using parametric model and attribute the efficiency and accuracy on drawing and calculating the quantity. The BIM is able to help productivity increase by using the builded model after we spend the effort building a model in early stage.

In Korea, BIM technology is applied mainly to building construction projects, but is expected to be applied rapidly to civil engineering projects because the government is currently considering the mandatory application of BIM for infrastructure facilities. Because the infrastructure project is processed in a horizontal work area, the application of BIM technology is more useful in the schedule management of the construction phase than the interference management of the design phase. The 4D CAD system is a typical BIM technology applied to the schedule management in the construction phase, but the application to the actual project is limited due to the lack of practical functions. This study examined the functions of four representative 4D CAD systems commercialized so that the selection criterion can be provided according to the characteristics of the project, and suggests that the functions that should be improved to have practicability. As a result of functional analysis, the application characteristics of each system were analyzed and the user convenience was suggested. In addition, a linear 4D simulation methodology was developed to improve the functions applicable to civil engineering projects, and ways to improve the utilization of the infrastructure projects as the construction phase BIM were suggested. In railway and road construction projects, most activities, such as earthwork, bridges, and tunnels proceed along the distance axis in a horizontal space. Therefore, a linear 4D simulation method, in which an activity is expressed along a distance axis, can be more practically useful rather than a simple 4D simulation method with a Gantt chart.

In the fields of design within civil engineering, BIM based Utilization of 3D object model is still far from commercialization. In this paper, BIM based 3D object model is composed for PSC box girder, super structure of railway bridge. The basic unit of the model is part model. The part model is the minimum unit model. And it has hierarchy to reflect the characteristics of structures. Change orders of structural designer must be reflected quickly in the 3D object model. Repetitive change orders are occurred in actual construction process. To prepare that, we classified design variables to parameters. Change orders of structural designer can be reflected quickly in the 3D object model because those parameters are related with information of 3D object model. In this paper, we studied various benefits of BIM based design method with 3D object model in the fields of design within civil engineering, and proposed the efficient application method of 3D object model for PSC box girder.
