Automation and robotic technology (ART) has been successfully applied in the manufacturing and allied industries to achieve on-time delivery of quality products at increasingly reduced costs. Meeting time, quality and cost targets still remains a big challenge in the global construction industry with prevalence of time and cost overruns. Application of ART in the construction industry could contribute to significant improvement in the efficient and effective delivery of projects to meet and exceed client expectations. However, the uptake of ART is still low in the construction industry. This study investigates the various ways in which ART could be applied to improve construction project delivery, potential areas of applications, and constraints to the uptake of the technology in the construction industry. Recommendations are made for improving the uptake of ART in the construction industry.

Automation in construction has been restricted to special classes of tasks. Curtain walls can be handled like standard construction materials; they are heavy but breakable, and are large but require precise installation. These characteristics make the installation of curtain walls ideal for robotic automation. There are two methods for developing construction robots: The first is approving the robot performance and applying it to the current construction methods. The second is admitting the limitation of the current robot technology and trying to optimize the current method of construction to apply the robot system. In this study, we derived the performance requirements of a curtain wall-installation robot. We also tested this robot at a real construction site and evaluated its performance. Finally, the results were analyzed, and we proposed additional research.

After the outbreak of COVID-19, the construction industry, which has more contact between workers than other industries, needs to improve its environment through the technology development for automation of construction projects. This study conducted 5-point scale surveys of 39 candidate technologies on 54 workers in construction- related industries to derive priorities for technology development to improve the construction environment. The result of this survey shows the top 10 candidate technology priorities, and this analysis can be used as basic data for setting the direction for future construction development.

This paper describes an automation of architectural design processes and the direction between this automation and robotic system in building construction using the concept of the object-oriented design in architecture. The research starts from the premise that many computer-aided design systems are mostly aimed at serving as drawing tools which are used only after a design formal solution has already been established by the architect. If the computer is well applied to the architectural design process, many positive things such as standardization of design detail, increasing productivity and collaboration, minimizing construction costs etc. can be done. To support an early design solution in the computer-based environment, the proposed automation was developed and tested in a real building project, using the object-oriented design concept such as product model. This design automation gives various design alternatives from the early design phase to the final stage of design details, according to musical harmony. This paper shows how architectural design process can be automated and how the data of the applied architectural design can be integrated into product model environment, in relation to robotic system in building construction.

Since most of the industries have adopted automation system, the industrial disaster has been declined sharply. Also automation system has offered many benefits such as productivity and assured quality. However, the construction industry is still relying on man power and because of this there are many victims occurring due to the industrial disaster. Construction industry has to overcome uncertainty of incidents and changing natural surroundings to actualize automation. Therefore, the efficient working plan and intelligent decision making process are needed to run more developed techniques and automations. Specially to decline the rate of industrial accidents occurred in basic construction in earth work, the automation via excavator is necessary and also the development of planning process system is too. This research is to establish Task Planning System to prevent disaster which is used for planning automated earth work.

Existing construction industry is composed of several processes with various characteristics. The tendency of current construction industry is getting complicated and diversified; it has limitation to solve problems through existing processes. As a problem-solving method, BIM (Building Information Modeling), environment to manage building life cycle from design and construction to management, is being suggested. Currently, BIM is only focused on technology development by engineers, and the automation of architectural theories is insufficiency except architectural design modeling. Therefore, this research aims to back up theses drawbacks through intellectual curtain wall arrangement by using musical proportions. In order to apply to construction automation, analysised of musical proportions method are performed. The BPMN-based Process Map is listed to develop IDM for the application to BIM Software.

For the past three years, the importance of automatic research has been increased. It was proved in previous research that the number of conducted research using 'Database' technique was the largest, but the amount of increase was the largest in research on 'BIM'. In consequence, it is predicted the research on 'BIM' will become a center of automation in construction. Therefore, the purpose of this paper is to examine trends though classifying into each construction phase and developed extent of techniques related to professionalization and integration with other techniques within a range of 'Automation in Construction Journal' which has the biggest level of awareness in construction field.

Denoising, registering, and detecting changes of 3D digital map are generally conducted by skilled technicians, which leads to inefficiency and the intervention of individual judgment. The manual post-processing for analyzing 3D point cloud data of construction sites requires a long time and sufficient resources. This study develops automation technology for analyzing 3D point cloud data for construction sites. Scanned data are automatically denoised, and the denoised data are stored in a specific storage. The stored data set is automatically registrated when the data set to be registrated is prepared. In addition, regions with non-homogeneous densities will be converted into homogeneous data. The change detection function is developed to automatically analyze the degree of terrain change occurred between time series data.

본 논문은 건설사업 프로세스를 모델링하고 자동화시키기 위해 개발된 핵심 기술을 제시한다. 비즈니스 프로세스 리엔지니어링 (Business Process Reengineering: BPR)과 비즈니스 프로세스 자동화 (Business Process Automation: BPA)는 건설사업관리에서 중요한 요소기술로 인식되어 왔다. 그러나 기존은 BPR 기법은 어떤 프로젝트를 조달하는 데 있어서 수천 개의 비즈니스 프로세스를 식별(identify), 문서화(document), 구현(implement), 실행(execute), 그리고 유지관리(maintain)하기위해 많은 노력이 필요하다. 그에 더해서 기존의 전사적 자원관리 시스템 (Enterprise Resource Planning: ERP)에 사용되어온 BPA 기술은 건설사업 프로세스 관리를 위한 효율적인 확장성 (혹은 범위성)을 제공하는 데 적합하지 않다. 워크플로와 객체기술(object technology)이 응용은 건설업계에 확장성이 있는 기업용 응용프로그램을 구축하는데 매우 효율적일 것이다. 본 논문은 건설사업 프로세스 자동화를 위한 기술들 및 방법론을 다음의 내용을 포함하여 제시한다. 1) 자동화된 건설관리 단위업무들이 캡슐화된 소프트웨어 부품으로 개발되는 방법. 2) 프로세스 모델링이 자동화된 건설관리 단위업무들을 마우스로 드래그-앤-드롭 (Dragging-and-Dropping)만하면 되도록 모델링 절차가 용이하게 된 방법. 3) 사업 요청들(business requests)을 발의하고 이러한 요철등에 상응하는프로세스 인스턴스(process instances: 프로세스 수행단계에서 실행된 프로세스)를 생성하는 방법, 그리고 4) 비즈니스 프로세스 인스턴스가 실시간 시뮬레이션 엔진(real-time simulation engine)을 기반으로 하는 워크플로 기술을 사용하여 실행되는 방법. 본 논문은 의도적으로 단순화한 건설장비 예약 및 취소 프로세스를 사례로 사용하여 어떻게 건설 사업 프로세스 자동화가 달성되었는지를 제시한다.
