본 연구에서는 3차원 지형공간정보를 기반으로 한 정밀한 토공량 모델링을 통해 토목 건설공사의 효율성을 향상시키기 위한 토공량 계산 프로그램인 EWS 프로그램을 개발하였다. EWS 프로그램은 LiDAR DEM을 이용한 정확한 토공량 계산과 건설장비의 단위 작업량을 기반으로 한 토공 공정계획수립이 가능하도록 개발되었다. 또한 계산된 결과를 건설현장에서 보다 직관적인 이해하고 이에 따른 분석 결과를 쉽게 공유할 수 있도록 하기 위해 Google Earth를 이용한 3D 가시화도 지원이 가능하다. 개발된 프로그램의 현장 적용성 검증을 위해 DAS 프로그램과의 토공량 계산 결과 및 토공 이동계획을 비교하였으며, 검증을 위한 대상지역으로 경기도 포천시 신북면 일원의 신포천 변전소 건설현장을 선정하였다. 최종적인 비교 결과, 본 연구에서 개발된 EWS 프로그램을 이용하는 경우 정밀한 3차원 지형공간정보를 통해 정확한 토공량 계산이 가능하며, 보다 합리적인 토량 이동계획 및 토공작업의 수립할 수 있어 건설현장에서의 생산성 향상 효과를 기대할 수 있을 것으로 판단되었다. In this study, EWS (Earth Work System), the earth-volume estimation program was developed in a way that could enhance efficiency of civil engineering construction through precise earth-volume modeling based on the 3D geospatial information. In this program, it is possible to estimate the precise earth-volume using LiDAR DEM and to establish the earth work plans based on the unit workload of the construction equipments. Also, EWS program can support the 3D visualization of the final results through Google Earth in order to understand intuitively or share the results of earth-volume estimation in the construction project. For verifying the possibility of appling EWS program to construction project, the construction site of Shin-Pochun substation in Shinbuk-myun, Pochon-City, Kunggi Province was selected as a study area and the results of earth-volume and earth work plans estimated from EWS program were compared with those of DAS program. As a result of comparison between EWS and DAS program, the more accurate earth-volume can be estimated by using 3D geospatial information and more reasonable earth work plan can also be established when use the EWS program was developed in this study. Thus, EWS program can enables improvement of productivity by establishing efficient construction plan in the construction site.

In this study, I executed civil engineering design and compared it with the existing method in order to analyze the expected effect of civil engineering design by using three dimensional space information and its advantages. Through a series of processes, it is possible to enhance the usability of three-dimensional space information, expected more accurate calculation of earth work and proceed with more reasonable construction in soil conversion and civil engineering work. Also, it enables improvement of productivity by establishing efficient construction plan.

본 연구에서는 단지 설계과정 중 토공사의 효율성을 증진시키고, 토공계획에서 시공에 이르는 연결방안으로 3차원 지형공간기반의 토공모델링에 의한 설계가 가능하도록 토공설계 프로그램을 제작하였다. 토공량 산정시 측량자료를 3차원 격자 DEM을 작성하여 정밀한 토공량 산정을 가능하게 하였고, 이를 기반으로 토공이동과 장비활용이 가능하도록 토적표를 구성하였다. 토공작업에 소요되는 각종 건설장비의 재원을 고려하여 이동토량 및 경로가 표시되도록 하였으며, 공사진행상황파악이 가능하도록 open API 기반의 KML 형식으로 결과를 저장하여 3차원 가시화의 직관적 이해를 높이고 분석결과의 공유가 용이하도록 제작하였다. In this study, an earth work design program which will improve the efficiency of earth work and enable to carry out the design using 3D Geospace-based earth work modelling in design stage was developed. Estimate of accurate earth work volume is achievable using 3D grid DEM, and based on this, a mass calculation chart was developed for movement of earth and equipment. In consideration for the resources for various construction equipments needed for civil engineering works, soil conversion and the passage is displayed. In addition, the result is restored in the form of open API-based KLM to make it possible for the users to identify the progress of the construction, thereby enhancing the intuitive understanding of three-dimensional visualization and making it easier to share the result of the analysis.

The Ubiquitous Technology refers to a new paradigm of intellectualizing physical space and organically integrating its objects through the means of ubiquitous computing and network. The forthcoming ubiquitous revolution is expected to serve a significant role in a sense that intelligent integration of heterogeneous physical space and its components connected to cyberspace will allow communal development of unified space of what can be called as a fourth dimension spatial revolution. And for such development of ubiquitous, technical complicity of location based GIS(Geographic Information System) technology applied to the three-dimensional spatial space construction process is essentially preferential. The manuscript therefore, serves to give systematic methods of illustrating Application of GIS Technology in the Ubiquitous for construction process.

Due to the availability of facilities, the importance of safety monitoring is increasing. Therefore, the introduction of Ubiquitous technology to replace the existing manually-operated methods is required. In this study, a web-based GIS system that provides monitoring information of bridges in real-time for the application of a bridge management system through the use of ubiquitous technology is constructed. Particular attention is given to the effective interconnection of bridge monitoring information and bridge management system and, through a ubiquitous environment, how to connect this with the UFID(Unique Feature Identifier) and the GIS-based bridge management system (BMS) operated by the Ministry of Construction and Transportation. In addition, data expression methods are also suggested that state the detailed locations and attributes of structures in bridge management by using GIS.
