Recently, the interest and demand on free formed structure providing aesthetic value as well as functionality has been increasing. Formwork has numerous advantages such as high strength, convenience, accuracy and good quality of surface roughness. Nevertheless, it increases construction cost and period to build complex shapes. For these purpose, deposition construction systems such as Contour Crafting and Concrete Printing have been developed with active collaboration between university and industry by applying the rapid prototyping technology to the construction industry in USA and England. Since there has been no related research in Korea, the possibility of spin-off technology and its fusion cannot be expected. In this paper, design elements including mechanical system and control system related to automatic deposition construction system prototype for constructing a free curved structure without mold are described. As for an appropriate material for the system, fiber reinforced mortar was selected by experiments on compressive strength, fluidity, viscosity and setting time. By performing transfer and extrusion experiments, the possibility of the development of deposition construction system was demonstrated. Based on this research results, it is required to keep the automatic deposition construction system improve and extend it into the new application area in construction industry.

인텔리전트 빌딩(IB : Intelligent Building)이란 용어가 처음 사용된 것은 1984년 1월에 미국의 코네티컷주 하트포트에 건설된 시티 플레이스(City Place) 빌딩에 빌딩 자동화(BA : Building Automation), 사무 자동화(OA : Office automation), 통신(TC : Tele-Communication) 시스템을 구축한 UTBS(United Technologies Building System)사가 빌딩의 특징을 설명하면서부터였다.

국토해양부에서는 건설산업의 투명성을 제고하고 생산성을 향상시키기 위해 1990년대 후반부터 건설사업정보화(CALS : Continuous Acquisition and Life-cycle Support) 사업을 진행중에 있다. CALS는 제조업의 모든 상품, 즉 주요장비 또는 다양한 상품 등을 획득하기 위한 설계, 생산과정, 또는 보급, 조달 및 이를 운영하는 운용지원과정을 연결시키고, 이들 과정에서 사용되는 각종 정보를 표준이라는 공통 창구를 통해 디지털화하여 컴퓨터상으로 정보를 통합하여 자동화시키는 개념이다. 이는 컴퓨터 네트워크를 이용해 상호 교환이 이루어지는 자동화되고 통합된 환경으로 변환시키는 정부와 기업간의 경영전략이라고 볼 수 있다. 이러한 개념에서 확장된 건설CALS는 건설공사 전 과정, 즉 기획, 설계, 조달, 시공, 유지보수 등의 과정에서 발생하는 각종 정보를 다양한 이해당사자가 교환하고 공유하기 위한 개념으로 출발하였으며, 현재 이를 지원하기 위한 5개의 단위시스템을 개발하여 운영중에 있다. 이중 용지보상시스템은 건설공사의 업무중에 시공단계에서 이루어지는 보상업무를 지원하는 시스템이다. 보상업무는 건설사업 과정 중에서 민원인과 직접대면하는 일이 많고, 액수도 클 뿐만 아니라 개인의 소유권과 밀접한 관계가 있기 때문에 분쟁의 소지가 매우 많다. 이에 본 논문에서는 보상업무 수행시 다양한 이해당사간의 각종 보상자료 교환체계 확립을 통한 업무 선진화방안 제시를 통해 업무의 투명성을 최대화하고 민원을 최소화하여, 보상업무 담당자에게는 업무의 효율성을 제고하고 민원인들에게는 국가행정에 대한 신뢰도를 높일 수 있는 보상업무 선진화 방안을 제시하고자 한다.

The construction industry is an inevitable part of modem development. Now-a-days, the construction industry experiencing several issues related with the maintenance of productivity, quality and labor. Hence there is an immediate requirement for the development of technologies enabling the automated construction equipment. The new technologies should also assure the sufficient safety and efficiency. In the present investigation, an attempts have been made for the development of object sensing algorithm and safety control system for intelligent excavating system. we have analyzed some elemental technologies for sensing objects and also proposed a technology for safety control system as well. The proposed technology will highly influence the safe working performance of construction industry in the positive sense.

수문자료는 국가적으로 중요한 자료로서 이에 대한 품질관리가 반드시 필요하다. 이에 우리나라 국토교통부에서는 국가 수문자료 품질관리시스템을 구축하여 실시간으로 수집되는 수문자료의 품질을 관리하고 있다. 국가 수문자료 품질관리시스템에서 사용되는 수문자료 자동점검기준은 실시간으로 수집되는 수문자료의 상태를 구분하기 위한 점검방법에서 설정한 기준 값을 말하며, 특히 수문자료의 오류 추출을 자동화하는데 핵심적인 역할을 하는 값이다. 해당 값은 점검 방법에 따라 다른 형태를 갖고 있으며, 관측소의 관측특성과 밀접한 연관이 있어 실무에서는 기존 관측자료의 통계적인 특성을 이용해 초기값을 추정하고 이후 관측자료들에 대한 실제 품질 판정을 기준으로 실제 상황을 고려하여 주기적으로 관리자가 수작업에 의해 시행착오법으로 보정하는 방법을 사용하고 있다. 이에 본 논문에서는 국가 수문자료 품질관리시스템에서 활용하고 있는 수문자료 자동점검기준을 대상으로 기존에 수작업으로 진행되던 자동점검기준의 보정을 자동화할 수 있는 평가지표와 평가 알고리즘을 개발하였으며, 이를 실제 자료에 적용하였다. 개발된 알고리즘은 그림1과 같은 추정 이상치 집합과 실제 이상치 집합의 상관관계를 이용하여 두 집합의 교집합인 A를 증가시키는 구조이다. 이를 이용해 자동점검기준의 적중률을 향상시킬 수 있었으며, 향후 실무에 적용될 경우 수문자료 자동점검기준을 신속하고 적절하게 보정함으로써 수문자료 품질관리업무의 효율성을 향상시킬 수 있을 것으로 기대된다.

With the development of technology, there has been a considerable increase in the number of skyscrapers in the world. Accordingly, there are increasing requirements with regard to maintenance, such as cleaning, painting, and inspection. However, it is extremely dangerous to work on the walls of buildings, and falls from buildings have accounted for a large proportion of construction accidents. In particular, as the number of buildings with irregular shapes increases, the accident rate during maintenance work has increased each year, with most accidents leading to deaths. An alternative solution must be developed with the commercialization of automatic systems. In this study, fundamental research has been conducted for drafting and commercializing an automation tool with a built-in guide system that can perform cleaning.

Recently, for the stabilization estimation of structures, many automatic measuring instruments with expensiveness and high accuracy have been developed and utilized. However, the existing manual measuring systems are almost impossible to measure the real-time for the whole surface of large-scale structures and an automatic measuring system has disadvantages with demanding enormous expense. In this study, 3D digital visual monitoring system was developed by using digital photogrammetry technique. To confirm application of developed system, it was applied to the measurement of the wall displacement of concrete surface and displacement measurement of reinforced-soil wall block. Then, the result of the test was compared with measuring value of total station. Based on the results of the comparison, the application of visual monitoring system was evaluated. The results show that the developed visual monitoring system could be available in displacement measure of structures.
