This paper introduces recent applications of three-dimensional building/construction data modeling (3D) and building information modeling (BIM) to large-scale complex building construction projects in Japan. Recently, BIM has been utilized as a tool in construction process innovation through planning, design, engineering, procurement and construction to establish a front-loading-type design building system. Firstly, the background and introduction processes of 3D and BIM are described to clarify their purposes and scopes of applications. Secondly, 3D and BIM applications for typical large-scale complex building construction projects to improve planning and management efficiency in building construction are presented. Finally, future directions and further research issues with 3D and BIM applications are proposed.

In order to apply the BIM technology effectively and efficiently during the life-cycle of project, it is important to deliver a accurate information on BIM from designer, and it should be used effectively at construction or maintenance stage. However, stakeholders have created a new BIM model at each phase in many practise adopting BIM, not used BIM generated in design stage. Because they have different purposes for using BIM, and deliver the BIM model without the sufficient explanation or application. It is necessary to define the range of usable BIM in construction phase with analyzing clearly the BIM created in design phase, and determining the difference with required BIM in construction phase. Therefore, this study propose a method for construction c

In South Korea, there have been attempts to enhance BIM work practices in various aspects. Public Procurement Service(PPS) has recently published 'basic guidelines to improve BIM work practices in construction and facility management'. It defines roles and responsibilities of project members in their application of BIM. It also developed a set of modelling standards and guidelines for effective model creation, management and communication among BIM users. Moreover, numerous construction companies have tried to cultivate BIM specialized manpower throughout entire construction phases. However, there are still challenges faced by firms during BIM adoption. Therefore, this study aims to provide practical counsel for construction companies to help them create optimized facilities and deliver high performance by analyzing BIM-based domestic construction projects in Korea from 2009 and 2015. The study will investigate types of client, project, BIM application range, and application technology.

Building Information Modeling (BIM) and its different work streams, such as 4D planning (4D), are among the major drivers for change in the construction industry. The primary aim of this research is to create a holistic map of both the barriers and drivers affecting the industrial uptake of BIM and 4D through the use of an extensive literature review and a survey of contractors and consultants from the UK AEC (Architectural, Engineering and Construction) industry. This research demonstrates that while non-technical barriers such as the inefficiency in the evaluation of the business value of BIM and 4D; the shortage of experience within the workforce, and the lack of awareness by stakeholders are recognized by professionals as main barriers to BIM and 4D adoption, current research is still largely concerned with technical advancement of BIM and 4D technologies. A holistic map of the driving and restraining forces affecting BIM and 4D widespread adoption was provided. The tackling of the non-technical barriers identified will help bridge the gap between technology, end-users and their processes.

Building Information Modeling(BIM) technology continues to develop and is now being applied to infrastructure facilities. As smart technology based on BIM is applied to the construction industry, the construction of the same data in a common environment is considered to be a very important step in various applications. This study was conducted on methods to establish an open BIM-based airport facility information common data environment. Therefore, this study develops the element technology to establish a common data environment for the integrated management of airport facility information, and aims to standardize data in the common data environment among various technologies and applications. In order to achieve the aim, in this study, the required technologies were derived by examining the common data environment and examining the civil engineering facility field and the case of integrated airport facility management. Through this, standards and development for information standard framework, information requirement level, BIM guidebook, and BIM library were developed in connection with national and higher standards. Through these standards, it is expected that the integrated management of various airport facilities will be efficiently carried out through a standard data platform in the future.

Especially for resolving BIM data compatibility issue, as one of recently raised BIM technology issues, has also been improved by using open BIM, representatively using IFC (Industry Foundation Classes) format. As shown in many case studies, usefulness of BIM technology is increasing day by day, and the IFC-based open BIM technology is essential in recent AEC projects where the productive collaboration is of importance. One of current problems in actual projects is that there is a conflict between conventional ways and newly developed BIM ways. Using both conventional and new technologies leads construction workers to having more work loads, consequently the efficiency and productivity of on-site workers have been decreased. Thus, it is strongly necessary to facilitate 3D BIM models to extract and generate 2D precision drawings in automation, especially using open BIM technologies. Some native BIM authoring tools have limitations in there automatic generation of 2D drawings, and there is no standardized mechanism to generate 2D drawings from heterogeneous applications. For this reason, this paper aims to develop an automated stand-alone program to generate 2D drawings in automation using IFC file, totally independent from various BIM authoring tools. By using the application described in this paper, any type of general drawings such as plan, section and elevation can be extracted without additional efforts. The development approach described in this paper, based on the open BIM technologies, has a strong impact to the current process especially in the perspective of enhancing productivity when we need to find out a trade-off in-between conventional and new approaches.

최근 유지보수 등의 목적으로 다양한 건설 및 건축 분야에서 스캔 프로젝트가 수행되고 있다. 스캔된 결과로 생선된 포인트 클라우드는 스캔 대상물을 표현하는 수많은 점들로 구성되어 있다. 이런 스캔 데이터에서 치수를 포함한 필요한 정보를 추출하는 과정을 역설계라 한다. 포인트 클라우드를 BIM으로 모델링하는 역설계 과정은 수많은 수작업이 포함되어 있다. 시간이 많이 소모되는 역설계 작업 특성상 설계변경 같은 재작업 요청이 발생되면 비용은 기하급수적으로 증가한다. 역설계 자동화 기술이 이런 문제를 개선하는 데 도움을 줄 수 있다. 하지만, 역설계 산출물은 유스케이스에 따라 가변성을 가지며, 산출물의 종류와 상세수준은 달라질 수 있다. 이런 점을 고려해, 본 연구는 건축물 평면객체 기본 형상(primitive geometry)에서 BIM객체로 자동 맵핑하는 G2BM(Geometry-to-BIM mapping) 규칙 정의 방법을 제안한다. G2BM는 사용자 활용사례 가변성을 고려한 건축물 평면 BIM객체 역설계 프로세스 정의와 사용자화 방안을 제안한다. 그리고, 프로토타입을 통해 이에 대한 효과를 확인한다.

This study aims to provide power monitoring system for super tall buildings with 3D BIM (Building Information Modeling) technology. In order to realize this subject, standard specifications for BIM objects and attributes were studied through analyzing processes and elements of electrical utilities for power management systems applied for super tall buildings. These standard BIM specifications could be used by designers, contractors and facility operators, and thus could be helpful to realize BIM information sharing between multiple disciplines and construction phases. And further study has been suggested to develop standard specification and applications from this study.
