건축프로젝트의 성공적인 수행을 위해서는 현장 조직의 커뮤니케이션 수준을 높여서 조직 구성원의 협업 능력을 향상시켜야 한다. 따라서 본 연구의 목적은 건축프로젝트 현장 조직을 대상으로 현장 조직 커뮤니케이션이 프로젝트 성과에 어떤 영향을 미치는지 파악하는 것이다. 연구 결과 커뮤니케이션 품질은 프로젝트 성과에 긍정적인 영향을 미치며, 정보공유는 프로젝트 성과에 부정적인 영향을 미치는 것으로 나타났다. 따라서 건축프로젝트 성과를 향상시키기 위해서는 현장 조직에서 정보공유를 일정수준 이상 달성해야 하고, 커뮤니케이션 품질을 향상시켜야 한다. 본 연구 결과는 건축프로젝트 현장 조직의 수행관리 체계를 구축하는데 기여할 수 있을 것이다.

Infectious disease emergency hospitals are usually temporarily built during the pneumonia epidemic with higher requirements regarding diagnosis and treatment efficiency, hygiene and safety, and infection control.This study aims to identify how the Building Information Modeling (BIM) + Industrialized Building System (IBS) approach could rapidly deliver an infectious disease hospital and develop site epidemic spreading algorithms. Coronavirus-19 pneumonia construction site spreading algorithm model mind map and block diagram of the construction site epidemic spreading algorithm model were developed. BIM+IBS approach could maximize the repetition of reinforced components and reduce the number of particular components. Huoshenshan Hospital adopted IBS and BIM in the construction, which reduced the workload of on-site operations and avoided later rectification. BIM+IBS integrated information on building materials, building planning, building participants, and construction machinery, and realized construction visualization control and parametric design. The delivery of Huoshenshan Hospital was during the most critical period of the Coronavirus-19 pneumonia epidemic. The development of a construction site epidemic spreading algorithm provided theoretical and numerical support for prevention. The agent-based analysis on hospital evacuation observed "arched" congestion formed at the evacuation exit, indicating behavioral blindness caused by fear in emergencies.

A computer vision-based scene recognition algorithm is proposed for monitoring construction sites. The system analyzes images acquired from a surveillance camera to separate regions and classify them as building, ground, and hole. Mean shift image segmentation algorithm is tested for separating meaningful regions of construction site images. The system would benefit current monitoring practices in that information extracted from images could embrace an environmental context.

BIM is a practical and economical technology used in the construction process. Despite the fact that BIM is widely used in the design and another stage before construction, it is not largely applied during the construction stage itself. However, it is important to opt for BIM during construction stage because there may occur a number of risks such as construction delay and increased construction costs. Therefore, the present paper contains the analysis of the model use, which is mainly applied to respond to the BMI RFI that represents an information requirement of construction site workers, by analysing the BMI RFI application at the construction site. In addition, there is an analysis of the way the derived model use affects the project goal aimed at the project success.

The augmented reality (AR) has recently became an attractive technology in construction industry, which can play a critical role in realizing smart construction concepts. The AR has a great potential to help construction workers access digitalized information about design and construction more flexibly and efficiently. Though several AR applications have been introduced for on-site made to enhance on-site and off-site tasks, few are utilized in actual construction fields. This paper proposes a new AR framework that provides on-site managers with an opportunity to easily access the information about construction resources such as workers and equipment. The framework records videos with the camera installed on a wearable AR device and streams the video in a server equipped with high-performance processors, which runs an object detection algorithm on the streamed video in real time. The detection results are sent back to the AR device so that menu buttons are visualized on the detected objects in the user's view. A user is allowed to access the information about a worker or equipment appeared in one's view, by touching the menu button visualized on the resource. This paper details implementing parts of the framework, which requires the data transmission between the AR device and the server. It also discusses thoroughly about accompanied issues and the feasibility of the proposed framework.

최근에는 시각적으로 건설현장을 효율적으로 관리하기 위한 다양한 방법이 시도되고 있으며, 특별히 폭이 좁고 거리가 긴 건설현장의 육상보다는 공중에서 무인항공기(UAV)나 드론(Drone) 등에 의하여 실시간으로 현장의 상황을 시각적으로 촬영하여 기록하거나 분석할 수 있는 방법이 매우 유용하다. 본 연구에서는 현재 진행되고 있는 현장을 대상으로 무인항공사진촬영을 주기적으로 3회 이상 촬영하고 촬영시점에 주요 구조물에 대하여 USN 센서를 동시에 작동시켜서 건설현장에서의 공사 진행정도와 환경상태를 동시에 확인하고 매칭시킴으로서 건설현장의 영상정보와 환경정보를 효율적인 공사관리를 위하여 활용할 수 있도록 하는 것을 연구목표로 하였다. 그 결과, 건설 현장의 전문기술자뿐만 아니라 행정 관리자도 건설현장의 진행과정과 그 준공상황을 원하는 시점에 상세한 현장상황을 시각적으로 확인하고 적절한 예산투입과 적합한 자원의 지원에 있어서의 의사결정을 도울 수 있도록 함으로서 자연적인 환경요인에 의하여 수시로 변할 수 있는 건설현장의 안전관리와 재난예방, 다각적인 변화 요인의 검토를 각 분야의 전문가들이 함께 의논하여 최적의 해답을 도출하였다.

The proposed site selection for transmission system construction is applied by KEPCO's regulation of the site selection criteria and it is confirmed through the deliberation of site selection committee and talking with local authority, by means of study on Present status and site survey, to verify impediment of national land use and development plan. Therefore, it is true that KEPCO has difficulty in timely completion of power facility construction because of civil appeals due to insufficiently evaluate resistance factor of stakeholder and stubborn resistance of inhabitants. This paper describes the PEES(power effect estimation system) which contributed to timely completion of transmission system construction to solve the above difficulty by utilizing IT(Information Technology) such as GIS(Geographic Information System) and LiDAR for the proposed site section. PIES evaluates project impacts on commencement of construction and finds out counter measures then makes public construction information after prediction and analysis of stakeholder's resistance factor.
