The development of computer and information technology in Korean construction industry is accelerating its speed while the education of Universities regarding to those technology is hardly catching up. Students graduated from schools are having difficulties in adapting themselves into the technology and as a result the industry is operating its own educational problem for the newcomers. This research develops the educational program of computer and information technology in school and therefore enhance the adaptability of the students for the industry. The program is open from 2002 up to 2004 liking two courses and including 10 modules and a project. The educational program consists of computer labs and lectures or seminars. The result of the educational program enables students to understand the computer and information technology used in the industry, an to improve the interest and skills of those, and additionally to motivate themselves into participating the continuous research and development of the technology.

한국건설기술연구원 구조연구실에서는 한국전력공사 토건연구실과 공동으로 N5200기종을 이용하여 철근콘크리트로 된 건축라멘구조의 해석 및 설계를 일관작업으로 시행할 수 있는 프로그램 KARST.1을 개발하였다. 본래 OA(Office Automation)용으로 개발된 N5200 기종은 현재 많은 분야에 보급, 사용되고 있는 IBM PC호환기종 보다 그 보급대수는 적지만 국내 여러기관에서 사용되고 있으며 계속적인 기계 성능의 향상과 다양한 Utility를 제공함으로써 적용분야를 증가시킬 수 있으리라 본다. 그러나 과학기술용으로 적용하기에는 아직 불편한 점이 많아 이 기종을 사용하여 구조물해석, 설계용으로 프로그램을 개발할 때 발생된 문제점과 KARST.1의 기능 및 특징을 간단히 소개하겠다.

One-third of total energy and 50% of $CO_2$ emissions arise from construction phase. Because of this global amount of energy consumption and $CO_2$ emission, we must do our best to solve this problem. But our existing ways of meeting this problem has focused on the energy consumption saving of the construction and dwelling stage. On the other hand, we has been treated too lightly for handling the $CO_2$ emissions problem during the maintenance management and the demolition process so far,. In this paper, we quantitatively predicted and evaluated the environmental load in each construction step during all life cycle. And, we developed the environmental load assessment program for each construction step. And we proposed the reliable decision support model for objective and reliable environmental load assessment and reduction. This result must help the development of construction technology and low carbon & green growth.

Road construction projects are parcelled into sub-sections which are then tendered to individual contractors for construction. The type of work and equipments used are similar for each sub-section. However, such equipment are not shared on a regular basis among the contractors and only partially performed in an informal and ad hoc manner. Consequently, road construction equipment suffer from low utilization and increased leasing costs. Lean construction and Program Management approaches stress the importance of collaboration among individual participants in a way that increases the collective cost savings of the entire project. This research attempts to apply such theories with the notion that under utilization of expensive equipment can be improved by formalizing a way to enable the sharing of equipment in large, public sponsored, multi-sectioned road construction projects. A system was developed consisting of a set of criteria and processes that enables automatic allocation of equipment to multiple sites on daily basis, in a way that minimizes equipment costs and improves their individual utility. The system was then applied in allocating three different types of equipment to an actual road construction project with four sub-sections for three months. A new metric, nDPR showed that utilization improved for all equipment and also equipment related costs were decreased by 4.45%. Results also showed that increased shared opportunities of equipment correspond to an increase in utilization and cost savings.

Through the development of construction technology, various construction projects such as redevelopment projects, undergrounding of roads, expansion of subways, and metro railways are being carried out. However, this has led to an increase in the number of construction projects in existing urban centers and neighborhoods, resulting in an increase in the number of damages and disputes between neighboring buildings and residents, as well as an increase in safety accidents due to the aging of existing buildings. In this study, digital data was applied to a graphics program to objectify the progress of cracks by comparing the creation of cracks and the increase in length and width through photographic images and presenting the degree of cracks numerically. Through the application of the program, the error caused by the subjective judgment of crack change, which was mentioned as a shortcoming of the existing field survey, was solved. It is expected that the program can be used universally in the building diagnosis process by improving its reliability if supplemented and improved in the process of use. As a follow-up study, it is necessary to apply the extraction algorithm of the digital graphic data program to calculate the length and width of the crack by itself without human intervention in the preprocessing work and to check the overall change of the building.

우리나라 재해 중 사망사고가 가장 많이 발생하는 업종은 단연 건설업이다. 지난해에도 총 2,114명의 산업재해 사망자 중 621명(29.4%)이 건설업에서 발생했다. 이렇듯 건설업에서 사망재해가 많이 발생하는 것에는 여러 이유가 있겠지만, 그 중에서도 현장에서 체계적이고 시스템적인 관리 및 업무처리가 잘 이뤄지지 않고 있다는 것이 주 요인으로 꼽힌다. 이는 현장의 이동이 빈번하고, 일용근로자가 많다는 건설현장특성상 어쩔 수 없는 부분으로 여겨져 왔다. 이러한 상황 속에 최근 설계 도면부터 각종 안전장치까지, 수동적인 시스템을 탈피해 자동적인 시스템을 구축 확산하려 노력하고 있는 기업이 있어 주목을 끈다. 바로 자동화시스템 전문업체인 (주)제이엠디(이하 JMD)다. 이곳의 대표적인 제품으로는 철골 자동화 설계 프로그램인 'Marvel Shop'과 자동안전샤클 제품인 'MASS2 ss11'이 있다. 건설현장의 자동화를 지향하는 이들 제품을 한번 살펴봤다.

본 논문은 건설산업의 신뢰성 있는 온실가스 추정을 위해 건설단계에서 사용되는 장비, 자재 및 에너지 사용량에 따른 온실가스 배출량 추정방법론을 고찰하였다. 그리고 온실가스 배출량 추정모델인 Road Construction Emission Model과 시설물탄소배출량 산정 프로그램을 비교분석하였다. 건설장비만을 고려한 배출량 추정은 사용장비의 각종 특성에 따라 차이가 발생할 수 있고, 자재 및 에너지사용에 따른 배출량 추정은 장비의 사용이 대부분을 차지하는 토목공사에서 배제한 단점이 있다. 따라서, 건설산업의 온실가스배출량 측정은 장비의 사용 또는 자재 및 에너지사용에 따른 포괄적인 온실가스 배출량 추정과 이를 위한 기반확충이 이루어져야 한다.
