Research activities and discussions on specialized areas reflecting the specificity of landscape construction are necessary. Therefore, this study was conducted with the purpose of presenting basic data for efficient field management by deriving items necessary for safety management in landscape construction fields through experts' opinions. A survey was conducted using Delphi analysis to derive "management items" and "safety management items according to landscape type" for landscape construction field safety for a total of 15 landscape construction specialists. The survey results showed that four top items were derived from the "management items" for the safety of landscape construction fields; they include: "safety and health management organization and education," "industrial safety and health management expenses," "payment of personal protection," and "establishment of safety measures." In addition, two to five items for each higher item appeared and resulted in a total of 13 lower items. Personnel, organization, budget, etc. for safety management are always required in the field, and the monitoring part of whether these elements are working was also taken up as a management item. In the "Management items according to each landscape construction" a total of eight landscape type were distinguished, they include: 'Reinforced concrete work', 'Masonry work', 'Plaster's work', 'Waterproof work', 'Stone masonry work', 'Pavement work', 'Facilities work', and 'Planting work'. Furthermore, two to seven sub-items for each construction type were derived, and a total of 35 management items were presented.

Recently, research on digital twins to generate digital information and manage construction in real-time using advanced technology is being conducted actively. However, in the construction industry, it is difficult to optimize and apply digital technology in real-time due to the nature of the construction industry in which information is constantly fluctuating. In addition, inaccurate information on the topography of construction projects is a major challenge for earthmoving processes. In order to ultimately improve the cost-effectiveness of construction projects, both construction quality and productivity should be addressed through efficient construction information management in large-scale earthworks projects. Therefore, in this study, a 3D digital map-based AR site management work support system for higher efficiency and accuracy of site management was proposed by using unmanned aerial vehicles (UAV) in wide earthworks construction sites to generate point cloud data, building a 3D digital map through acquisition and analysis of on-site sensor-based information, and performing the visualization with AR at the site By utilizing the 3D digital map-based AR site management work support system proposed in this study, information is able to be provided quickly to field managers to enable an intuitive understanding of field conditions and immediate work processing, thereby reducing field management sluggishness and limitations of traditional information exchange systems. It is expected to contribute to the improvement of productivity by overcoming factors that decrease productivity in the construction industry and the improvement of work efficiency at construction sites.

GS E&C had developed construction management system, PMS which is based on EVMS in 1997. Recently, TPMS has developed for effective construction management through applying daily schedule management and JIT on materials, labors, equipments focusing field work. TPMS realizes "Shielding" and "Make-Ready Process" which are the main concept of Lean construction. Through this system, it can manage and plan daily field work, support the field work related material, labor, and equipment planning, and minimizes the non-valuable process. This paper introduces the concept of TPMS, and through established system, it can lead the construction culture and raise the competitive power of construction industry

Recently, defect management have been considered as one of the major issues for more large-sized and complicated in domestic construction industry. However, the defect management have not been performed systematically because of special manpower, excessive amount of documents, 2D based inspection work, unclear traditional checklists, complicated work process and difficulty in communicating construction information. Therefore, the construction field manager could not performed the quality inspection and defect management work on time as well as the reliability of recorded quality and defect factors was decreased. The primary objective of this study is develop a Construction Defect Management Application CDMA) using a mobile (smartphone). The application can be sharing a huge information and communication technology based on RFID (Radio-Frequency Identification), BIM (Building Information Modeling) which enables field mangers to efficiently gather the information of defection in construction on-site.

Nowadays the scale of domestic construction becomes large, sophisticated and specialized. It has led to a growing need for the high quality, cost reduction, safety and reduction of work duration. Therefore the importance of construction materials management is emphasized to perform the project successfully. It becomes an current issue about method of construction material management according to the flow of construction progress in the construction field. Therefore, various researches using RFID for efficiency of construction material are being studied. We analyzed the case study using RFID, drew the problems through the investigation of status about the management of material in the field, and then suggested the method of material management using in the apartment building construction field.

Recently, the scale of construction project is getting bigger compared to previous projects. Therefore, the job stress of the field manager responsible for the construction project is getting more and more intense. Therefore, construction companies should establish a job stress management plan for stable human resource management of the field managers. From this perspective, in this study was developed a job stress measurement system in connection with MBTI personality types. The developed system allows the job stress of the field manager to be judged on a scale from 1 to 9 points. Accordingly, it is expected that construction companies will contribute to the effective management of field managers in the future.

토목공사 발주기관은 공사현장이 대부분 원거리에 위치하고 담당공무원도 다수의 현장을 관리하게 되므로 간접적 방식으로 현장을 관리하고 있다. 토목공사 현장은 광범위한 작업구역을 가지므로 현장 실무자의 보고에 의한 간접적 관리방식으로는 사업전체의 현황을 신속하게 파악하기가 쉽지 않다. 이러한 문제점을 해소하기 위해 발주기관과 현장간의 현장관리시스템은 오프라인에서 온라인방식으로 변화되고 있다. 본 연구에서는 UAV에서 취득한 현장의 3차원정보를 활용하여 원거리에 위치한 현장과 감독기관간에 관련 정보를 온라인으로 공유할 수 있는 개선된 현장관리시스템을 제시한다. 이를 위하여 연구에서는 다수의 실제 현장의 현장관리 운영체계의 문제점을 분석하여 UAV활용 현장관리시스템에 필요로 하는 공사현황보고 및 온라인 정보관리 등의 주요기능을 도출하였다. 연구에서 개발된 시스템은 실제 공사 중인 현장에 적용하여 활용성을 검증하였으며, 다수의 현장 조사를 통하여 기존의 간접적 현장관리 방식과의 효율성 개선사항을 분석하였다.

After the construction participants system is abolished, expectations are high for its consequences such as liquidating paper-companies, holding back low price contracts, and improving multi-stepwise subcontract structure. However, the professional construction firms have been took responsibilities and obligations as businessmen employing the chief workmen and construction workers. For this reason, it is expected that they will be charged a great deal of expenses such as increase in labor management services and laborers, the occurrence of an retirement grants, insurance fees, etc. Since the hold on power of field managers are getting weaker toward the construction workers, it is most likely to have loss in efficiency of production in the long term. Therefore purpose of this research is to analyze difficulties and the point at issues with which professional construction firms are undergoing after abolishing the construction participants system by investigating on the actual condition in the field management. For this research, we got a grip on the actual condition and analyzed the rise of a primary factor on reinforced concrete construction.

복합, 대형화되는 건설현장에서 사용되는 건설정보들의 양은 방대해지고 이에 따라 효율적인 건설현장 관리의 중요성이 대두되기 시작하였다. 따라서 본 연구에서는 BIM의 이론적 고찰과 국내외 사례조사를 통해서 BIM의 적용 현황 및 가능성을 파악하고 건설현장의 수행단계별, 협업주체별 중심의 분석을 통해서 효율적인 건설현장 관리모델의 구축 방향을 제시하고자 한다. BIM을 적용하여 목적 건축물의 3D Modeling을 통한 2D 도면의 시각화, 도면 오류의 사전 발췌로 시간적, 금전적 손실을 최소화, 3D 모델의 물량정보로 예산 작성의 정확성을 향상, 정확한 도면의 건축정보와 물량정보로 공사 진행 방향 설정에 확실성을 부여 및 부위별 객체 정보를 포함한 BIM기반의 건설정보를 바탕으로 공정관리를 통한 원가관리, 품질관리가 가능함을 알 수 있었다. 이 과정을 통해 BIM정보를 통합하고 연계함으로써 현장과 각 협업주체들 간의 건설현장 관리의 효율성을 향상이 가능하다고 판단된다. 추후에는 실제 건설현장 관리모델을 구축하고 실제 건설현장에 적용하여 검증을 하는 연구가 필요하다.
