High speed railroad project management has been almost completed by starting operation of Seoul-Busan high speed railroad with the exception of a few constructing blocks currently in April, 2004. After Korea Rail Network Authority was established in 2004, it needs to develop new project management system for both conventional railroad construction and high speed railroad construction for domestic railroad projects, while it plans to invest in overseas railroad project for logistics innovation and improvement in passenger transport services on a large scale. Therefore this paper provides the method that we can adapt the project management system for high speed railroad containing experiences and know-how from construction of high speed railroad for both conventional railroad construction and high speed railroad construction or improve project management system for high speed railroad to use it as project management system for overseas railroad projects.

In this study, the study was conducted to derive the utility of the safety management system applying block chain technology and big data technology to improve the problems of construction sites where concealment and operation of safety accidents occur. If block chain technology and big data technology are applied to construction safety management, transparent data can be collected, and based on the collected data, it is possible to predict accidents that can occur at the construction site and establish countermeasures. It can also be an opportunity to strengthen the safety awareness of construction workers and managers, and can clearly identify the responsibility in the event of a safety accident. This study suggests that the application of the 4th Industrial Revolution technology could be a great opportunity to innovate the construction industry which is less than other industries.

Recently, starting with smart construction research, interest in technology that automates construction site management using artificial intelligence technology is increasing. In order to automate construction site management, it is necessary to recognize objects such as construction equipment or workers, and automatically analyze the relationship between them. For example, if the relationship between workers and construction equipment at a construction site can be known, various use cases of site management such as work productivity, equipment operation status monitoring, and safety management can be implemented. This study derives a real-time object detection platform architecture that is required when performing construction site management using deep learning technology, which has recently been increasingly used. To this end, deep learning models that support real-time object detection are investigated and analyzed. Based on this, a deep learning model development process required for real-time construction site object detection is defined. Based on the defined process, a prototype that learns and detects construction site objects is developed, and then platform development considerations and architecture are derived from the results.

Although the safety management plan review system according to the Construction Technology Promotion Act for securing the safety of the construction work is a fundamental system essential for the prevention of the construction industry disaster, the necessity of its improvement has been raised because it often fails to meet the original purpose. In this study, through the analysis of the effect of the safety management plan and the problems of the operation, we suggest ways to improve it in view of the construction accident reduction and conducted surveys on the construction site through the questionnaires of the client, construction company, and construction business technology manager. In order to improve the effectiveness of this system as a result of the study, it is necessary to distribute the guidelines for the preparation of the safety management plan, manuals, etc., to simplify the contents of the safety management plan, also the step-by-step approval of the safety plan can be a solution. For this, it is necessary to revise the policy through consultation with the Ministry of Land, Transport and Maritime Affairs and related experts.

This paper concerns 3-D graphical modeling and simulation techniques for design and control of automated equipment for construction and facility maintenance. A case study on the use of 3-D graphics techniques for developing a power plant maintenance robot is presented. By simulating equipment operation within the 3-D geometry models of the work environment the environment design was improved. The 3-D graphical models of the equipment and the work environment were further utilized for the control of the robot from a remote distance. By presenting the real-time updated equipment configuration and the work environment to the operator, the graphical model-based equipment control system helped the operator overcome the problems associated with spatial perception. The collision between the robot and the plant structures was also avoided based the real-time analysis of the dynamically updated graphical models.

토공작업은 모든 종류의 토목공사에 기본이 되는 공종으로 공기, 공사비와 생산성에 영향을 미치는 요소이다. 토공은 그룹으로 형성된 다수의 건설장비들이 필요한 기계화 작업이며 건설장비로 인하여 많은 연료를 소비하는 작업이다. 그러나 일반적으로 토공작업은 건설장비 운전자의 경험과 직관에 의하여 수행되기 때문에 낮은 생산성, 높은 연료사용량 및 탄소를 많이 배출시킬 수 있는 문제점을 갖고 있다. 최근 연구에 의하면 이러한 문제점의 해결책의 하나로 건설장비 플릿관리 시스템이 제안되고 있다. 건설장비 플릿관리 시스템은 효과적인 토공계획, 최적의 건설장비 할당, 효율적인 건설장비 운영, 빠른 정보교환 등과 같은 기능을 수행한다. 본 연구에서는 건설장비 플릿관리 시스템 구축시 필요한 주요 방법론을 제시하는 것을 목적으로 하고 있다. 토공작업을 위한 3D 솔리드 파라메트릭 모델 형성, 옥트리를 이용한 토량배분, 건설장비 플릿구성 및 운영 방법론을 제시하였다. 건설장비 플릿관리 시스템의 효용성을 건설장비 가동률, 연료사용량, 이산화탄소 배출량 측면에서 검증해 보기 위하여 시뮬레이션을 실시하였다.

With the increasing public concerns on sustainability in construction industry around the world, a variety of standards for sustainable construction have been developed and implemented. However, most of the them focuses operation and maintenance phases and do not have been approached integrally in terms of all construction phases. Especially, considering the quantities of environmental loads occurred intensively at the construction phases, it should not be overlooked. Therefore, the purpose of this study is to deduct primary management works for reduction of the potential environmental loads at the construction phases. In order to assess them quantitatively, we conduct a survey from professionals who are in the relevant fields and analyze these data using Fuzzy-AHP.

This research investigates the feasibility of Web technology as a means of delivering facility information for better support facility operation and maintenance. Our research proposes a Web-based feedback system as a pragmatic solution to the limitations of current FM (Facility Management) processes. In practice work orders and records are often misplaced resulting in lower efficiency and customer satisfaction. This may be overcome by a system that states information digitally and provides a Web-based interface. The interface could allow customers to report facility problems, trace their work order in progress, view schedules for maintenance and provide feedback for service online. The benefit for a FM department is that it can receive feedback on performance which would improve the quality of service and build a record of practical experiences.

Since tunnel construction order was placed one by one, various sensors and actuators installed at the RTU and higher level system in each tunnel maintenance office had their own protocols depending on construction company. The TGMS testbed established on the extended region of Yong-dong Highway, for example, did not have consistent protocol between each automation levels and management levels without considering the functions and/or roles of each level. The management sever in each tunnel was simply networked to the TGMS server. Therefore, it is impossible to implement a new control algorithm as well as to integrate each other since each tunnel was constructed by different company. So, if the construction company is out of business, there is no way to maintain the corresponding tunnel effectively. In order to solve this problem, all the necessary standard protocols was established between automation level and management levels. These interface standards provide the clear classification between individual tunnel system and tunnel management system. So, even if construction company is different, its effect is minimized, so that it is expected to successfully establish PC based TGMS.
