Recently, researches on the construction information for construction of high-tech cities are under performed. RTLS(Real-Time location system) for gathering the dynamic location information of construction resources in construction sites, such as workers, materials and equipments, is one of the developments. Especially, construction resources can be managed efficiently with the dynamic location information and the improvement of safety and the reduction of cost are expected. To introduce the RTLS to the construction sites, the installation location of AP(Access Point) must be simulated using the 3-dimensional visibility analysis considering the propagation distance of AP. In this research, 3-dimensional signal simulation software based on the spatial data using surveying terrestrial LiDAR is developed. The simulated results are compared with the signal strength of field experiments for 4 test sites. As a result, the signal strength from the propagation model is most similar to that of field experiment at the front of the main building and the maul playground of Konkuk University. The visibilities in that sites are higher than other sites. among 4 test sites.

Recent advancement in ICT and IT infrastructure drives the construction industry towards a IT-based industry. Accordingly, the importance of the planning phase of a project is significantly highlighted due to recent large-scale national development projects such as U-city and multifunctional administration city. various development and studies are conducted on the convergence of 3D CAD and GIS in order to support the decision making by simulation of each phase of construction prior to the actual construction of a building. However there has been limits to the implementation of the IT technology in the planning phase due to its characteristics such as high reliability on the experts knowledge and the compliance of the administration work. In this study, a trendy issue of the convergence of the GIS technology with the 3D CAD design data is suggested to improve the efficiency of a decision support in the planning phase.

"군 소요(Requirement)"는 "과학기술(Technology)"을 이끌고 가는 견인차이다. "Technology push and Requirements pull"이란 법칙이 있다. 이 Push-Pull이란 법칙이란, 기술의 발전이 장차 전쟁수행방법에 있어서 그 기술을 적용할 군의 역할 혹은 미래군의 구상을 강요한다는 것이다. "첨단 무기체계일수록 국내에서 획득"하도록 국방과 학기술공동체(군.산.학.연)의 모든 노력을 통합하는 가시적인 조치가 절실히 필요하다. 특히, 군.방산간의 "조화와 협력"의 과학기술 기반이 구축되어 군이 방산이고, 방산이 곧 군인 풍토가 조성됨으로써, 우리도 신기술발전속도에 걸맞는 "21세기 정보화 과학화 군건설"이 가능할 것이다.

Construction incidents, mechanisms and causes in Geotechnical Engineering have been closely reviewed for the safety assurance during design and construction stages. The safety assurance is clearly related to the observational method in which design is reviewed during construction and contingency actions are undertaken successfully to minimise any potential failures. The observational method has been extensively applied for the construction of subways underground structures, dams and many important Civil Engineering projects in the past 20 years. But the number of serious construction incidents are growing for the past several decades. Therefore present development of observational method and improvement techniques are introduced with some case histories.

최근 NGIS, 토지정보관리체계화 등 중앙정부차원의 사업이나 도시정보화사업, 지하시설물 전산화 사업 등 지방자치단체를 중심으로 GIS를 활용한 사업이 본격적으로 시작되고 있다. 이 시점에서 일찍이 GIS에 대한 깊은 관심을 갖고 사업을 추진해 오고 있는 일본의 사례는 시사하는 바가 적지 않을 것이다. 이 글은 일본의 토지총합연구 1999년 가을호에 기고된 재단법인 일본건설정보총합센터의 히라이마사지 수석연구원의 글을 번역정리, 우리보다 앞서 GIS를 활용한 일본의 사례를 살펴보고자 한다.

Application of information technology for the construction area has been processed actively with the development of information technology. In this study, a framework of the Construction Specification IETM(Interactive Electronic Technical Manual) was suggested through the analysis of the Department of Defense(DoD)'s standards and the trend of techniques related to the IETM. As the Framework, the DFD(Data Flow Diagram) of the construction specification IETM's organizing and using procedure was suggested. And a Model of construction specification IETM was organized on the basis of DFD. Finally, a scenario was constructed by the pilot system which is based on the model. The application of the construction specification IETM would make efficient and effect task implementations possible. By that, in addition to the reduction of the cost and time, the quality enhancement from information missing protect effectiveness could be expected.

As the Scale of construction work is enlarged, complicated and diversified, construction information from the large number of construction sites is happened at site and reported to the head office. To simultaneously control the individual or large number of sites in large number of construction information, the necessity of making extract the important point of the information and the board of director's making a suitable decision to support the fields is increased. Also, as driving the construction industry to be informative, efficiently aggregating the information created in fields, efficiently making decision and controlling the construction work is increased the importance of the company's competitiveness factor. To simultaneously control multi-construction sites in the small and medium size construction firms define the fundamental and core information factor which needed in the head office and suggest the appling method.
