As the scale of construction work is enlarged, complicated and diversified, construction information from the large number of construction sites is happened and reported to the head office. To control much information generated in construction sites simultaneously, the necessity of supporting system which can extract necessary information is increased. However, compare with large companies, medium-sized companies's organization of head office and management system is weak, so it's difficult to manage multi-projects. Among these site managements, resource management is an important management area. But, resource planning is based on experience and judgement and have not associated with schedule information. So when schedule if changed, the plan must be amended manually. This study investigates material-planning model for multi-project management which is connected with daily report system and scheduling software.

Due to harsh conditions of construction site, understanding of current feature of terrain and other infrastructures is critical issue for site managers. However, because of difficulties in acquiring the geographical information of the construction sites such as large sites and limited capability of construction workers, comprehensive site investigation of current feature of construction site is not an easy task for construction managers. To address these circumstances of construction sites, this study deduce difficulties and applicabilities of unmanned aerial vehicle in the area of construction site management. To confirm applicability of UAV in civil construction project, case study have been conducted on the road construction project. The result of case study proved that the developed system is one of promising technologies that has been studied in construction site management. To improve applicability of UAV for construction and process management information, law and technical issues will be an important area of future study.

In order to achieve the best performance of a project, uncertainties involved in the building construction process need to be identified in the planning phase of the project. Risk management plays a significant role in construction to minimize risk occurred due to uncertainties of a project. Although the importance of the risk management has been known to the construction industry, a more effective system should be developed to meet the demands of the industry. The purpose of this study is to develop the effective risk management system for scheduling the construction processes. The study provides a tool that can optimize the management system which would assist managers to identify schedule risks in the planning phase of the project.

Recently, Housing projects in the center of the Metropolis are getting higher, larger, more complex gradually, the resources are increasing greatly. Especially, the right manpower in the right place could quite important factor because the construction cites are wide and many subcontractors and labors throw into finish works in High-rise Housing projects. Differing from apartment building projects. it is only four or five years that high rise building projects are started so, there is little data for manpower information. Furthermore it is difficult that the data gathering and managing because manpower management is usually used to execute by subcontractors from supply to demand. Consequently, this study, proposed develop management for accurate manpower plan and efficient collection and practical use of manpower information through analysis of present condition in construction sites

절도시설과 같은 광역지역 공사 현장에서는 다양한 요인을 갖는 공종별 위험요소가 존재하고 있으나, 현장에서 이를 효율적으로 관리할 수 있는 방안의 수립이 미흡한 실정이다. 따라서 본 연구에서는 철도 관련 실무자들을 대강으로 설문조사를 실시하여 공종별 위험 요인을 도출한다. 이를 통해 RBS(Risk Breakdown Structure)를 구축하고 제시된 RBS에 의한 위험도를 산정한 후 이를 기반으로 VR시스템과의 연동 및 위험관리 체계 구축 방법론을 제시하고 있다. 따라서 현장에서의 주요 공종별 Risk 위험도를 가상환경에서 구현이 가능하므로 위험요인에 따른 시설의 직관적 파악이 가능하다. 또한 시공자들은 나타난 시각화 정보에 의한 Risk에 대비해 효율적인 공사 관리를 이행할 수 있을 것으로 기대된다.

건설업은 전체 산업중 두 번째로 높은 재해율을 보이는 산업이다. 그중 거푸집 작업의 재해율은 건설업 재해율의 24%를 차지하고 있다. 거푸집 공사에서 발생하는 재해비율은 추락(30.4%), 물체에 맞음(20.8%), 넘어짐(19.1%), 부딪힘(13.1%), 끼임(8.3%)이다. 이중 가장 높은 비율을 차지하고 있는 추락에 대해서 재해요인 분석을 통하여 체크리스트를 개발 하였다. 본 연구에서 개발한 체크리스트를 중소규모 건설현장의 거푸집 공사에 적용한 결과 안전관리의 취약점을 파악할 수 있었다. 본 연구의 결과가 중소규모 건설현장에 적용하여 보다 효율적인 안전관리에 기여할 수 있기를 기대한다.

As the field report data does not normalize, ordering organization requires different form every time and field reporters make out form as random, data and report to the ordering organization by different medium such as FAX, e-mail, paper document. Therefore, Field reporters must set and make out same information in required pattern. And ordering organization is being responsible for side works of totalizing and processing the reported data. This research suggests the electronic document unification about monthly construction progress report and construction present condition report system. In addition, it suggests electronically processing function that can handle field report business to unifying electronic documents. As using the result of this research, it will improve the work efficiency and simplify in report business.

막대한 비용을 들여 모든 건설공사에서 시행하는 지반조사의 결과물을 현재는 종이문서 형태로 각 관리주체가 개별적으로 보관하고 있어 재활용과 공유가 거의 이루어지고 있지 않은 실정이다. 이를 데이터베이스화하여 웹을 통해 서비스함으로써 효과적인 저장과 활용을 유도할 수 있다. 그 일환으로 현재 웹 기반의 지반정보 통합 D/B 시스템을 구축, 운영 중에 있다. 현재는 지방국토관리청이나 공사현장과 같이 지반정보가 발생하는 기관 및 현장을 직접 방문하여 지반조사 결과물을 수집한 후 이를 전산화와 검수를 실시해 시스템에 반영을 하는 방식으로 지반정보를 데이터베이스화하고 있지만, 많은 시간과 비용이 소요되고 수집에 한계가 있어 이를 개선하기 위한 자동화시스템의 도입이 검토되고 있다. 지반정보의 수집, 전산화, 검수, 웹서비스의 일련 과정을 보다 자동화시키고, 효과적이며, 수집범위를 획기적으로 넓힐 수 있는 방안으로 웹 기반의 입력자동화 시스템 도입, 지반정보 관리 주체의 직접 입력 지침 마련, 입력 실무자에 대한 권한 부여와 사용자 교육 등에 대한 전략을 본 연구를 통해 모색해 보았다.

Construction industry try to use weather information because construction is much influenced by weather conditions. However, the researches, how to use the weather information in construction fields at present state, are not sufficient. Therefore, the purpose of this study is to present the methods for improving weather information application by analysis the present state in building construction fields. The results show that educations about application of weather information are poorly conducted though the construction engineers know that weather information is helpful to improve the performance and that weather information serviced is not suitable to apply their field's work. Based on the results, for improving the application of weather information, the construction engineers are structurally educated about applying weather information and the weather information system is developed to specialize the building construction projects. Additionally, construction companies have a long term plan to cultivate the experts who equally have a good knowledge and experience of weather information and construction technologies. These proposed methods help to decrease the influence of weather conditions and finally to improve the performance in building construction projects.

As plant market grows up, client demands to increase quality, technology and to reduce construction period. Due to the vast scale of the construction site and complexity of process, plant project can have some problems of communication among the project participants, the duplication of work, errors and rework. As a result those cause more costs, delay the construction schedule and reduce productivity and quality. Therefore, real-time communication between participants and real-time sharing of information such as material, equipment and construction are required in plant project site. This research aims to propose process and develop system using NFC(Near Field Communication) technology and augmented reality technology with mobile device for plant construction site. Administrators and operators are able to work efficiently using proposed process and system which create an environment designed to share and deliver information such as material, construction information.
