Recently BIM technology has been expanded for using in construction project. However its spread has been delayed than the initial expectations, due to the high-cost of BIM infrastructure development, the lack of regulations, the lack of process and so forth. Therefore, this research proposes the cloud computing based BIM service for saving the cost of BIM infrastructure development and providing various BIM Services to meet the domestic process. In order to achieve this, we perform a survey on the cloud computing based BIM service and develope the prototype system as the core technology of proposed service. The developed the prototype system consists of the IFC based BIM server for IaaS (Infrastructure as a Service) and the viewer for SaaS (Software as a Service). This research also conducts the performance test for their applicability and verifies that the results of this research can be used as core components in the cloud computing based BIM service.

최근 건설 분야에서는 3차원 설계로 대표되는 Building Information Model(BIM)에 관련된 연구와 현업적용이 활발히 시도되고 있다. 이런 추세에 맞추어 정부에서는 2013년부터 500억 이상의 공사에 BIM을 적용하기로 결정했다. 따라서 BIM의 핵심이라 할 수 있는 정보모델 관련 소프트웨어의 필요성과 활용의 공감대가 확산되고 있다. 또한 클라우드 컴퓨팅 기술의 보편화에 따른 가상협업환경이 도래하여 BIM 기반의 시설물 정보관리의 보급과 실용적 효과를 높이기 위해 건설과 ICT기술의 융합을 통한 미래 응용기술 연구가 무엇 보다 절실한 시점이다. 이 연구는 클라우드 컴퓨팅을 활용하여 BIM기반 서비스를 제공하기 위한 프로젝트의 전략적 접근방법을 다루고 있다.

The port BIM technology has many problems such as lack of relevant system, high cost of BIM infrastructure construction, and process difference of existing domestic inter-industry. Since the port facilities as national key industries are managed and operated by public organizations, it is necessary to integrate IT resources and have a system that needs collective construction and joint utilization management. In this paper, we proposed the convergence of cloud computing technology and BIM as a way to reduce the infrastructure cost required for port BIM operation and to provide various BIM services for domestic process. To do this, we collected system requirements based on demand surveys of port staff and designed a BIM browser that provides IFC-based BIM server and customized services to reduce infrastructure cost in cloud computing environment. In terms of infrastructure, we designed cloud-based IaaS to support cost reduction, which is an essential component, and designed SaaS to support customized services in terms of services. We will perform performance verification with focus on whether port BIM servers and browsers have reached a level where they can manage four BIM models with different types and capacities.

Recently, there have been various attempts for the adoption and spread of Building Information Modeling (BIM) in the construction industry. However, the spread of BIM has been less satisfied than expected, because of the insufficient, expensive hardware and software for the authoring, analysis and so forth. As a solution to resolve the obstacles, the applications of cloud computing technology to BIM have been introduced. Due to the vendor-dependent functions and lack of verification on the work process, the spread of cloud-based BIM has been limited in Korea. Therefore, this study proposes the functions of cloud computing services which can support BIM-based design processes through the review of practitioners, questionnaire survey and analysis of design process.

As project opportunities for the Architecture, Engineering and Construction (AEC) industry have grown more complex and larger, the utilization of Building Information Modeling (BIM) technologies for three-dimensional (3D) design and simulation practices has been increasing significantly; the typical applications of the BIM technologies include clash detection and design alternative based on 3D planning, which have been expanded over to the technology of construction management in the AEC industry for virtual design and construction. As for now, commercial BIM software has been operated under a single-user environment, which is why initial costs for its introduction are very high. Cloud computing, one of the most promising next-generation Internet technologies, enables simple Internet devices to use services and resources provided with BIM software. Recently in Korea, studies to link between BIM and cloud computing technologies have been directed toward saving costs to build BIM-related infrastructure, and providing various BIM services for small- and medium-sized enterprises (SMEs). This study addressed development of the usage metering functions of BIM software under cloud computing architecture in order to archive and use BIM data and create an optimal revenue structure so that the BIM services may grow spontaneously, considering a demand for cloud resources. For the reason, we surveyed relevant cases, and then analyzed needs and requirements from AEC industry. Based on the relevant cases, customizing for cloud BIM and design for the development was performed. We also surveyed any related-law to support cloud computing-based BIM service. Finally, we proposed herein how to optimally design and develop the usage metering functions of cloud BIM software.

Recently BIM technology has been expanded for using in construction project. Due to the high-cost of BIM infrastructure development, lack of regulations, lack of process and so forth, usage of BIM has been delayed than initial expectations. In design phase, especially, collaboration based on BIM system has been a key factor for successful next generation building project. Through the analysis of current research trends about IT technologies, virtualization and BIM service, data exchange such as drawings, 3D model, object data, properties using cloud computing and virtual server system is defined as a most successful solution. The purpose of this study is to enable the cloud computing BIM server to provide several main functions such as editing models, 3D model viewing and checking, mark-up and snapshot in high-performance quality by proper design of VDI system. Concurrent client connection performance is a main technical index of VDI. Through testing of test-bed server client, developed VDI system's multi-connect control is evaluated. Performance-test result of BIM server VDI effect to development direction of cloud computing BIM service for commercialization.

This study focuses on the new teaching assistance robot platform and the cloud-based education service model to support the server. In the client area we would like to use the teacher assistant robot in elementary school classrooms to utilize the language education service platform. Emerging IoT technology will be adopted to provide a comfortable classroom environment and various media interfaces. Extensive precedent review and case study have been conducted to identify basic requirements of proposed service platform. Embedded system and technology for image recognition, speech recognition, autonomous movement, display, touch screen, IR sensor, GPS, and temperature-humidity sensor were extensively investigated to complete the service. Key findings of this paper are optimized service platform with cloud server system and possibilities of potential smart classroom with intelligent robot by adopting IoT and BIM technology.
