Vast quantities of environmental pollutants from construction projects are causing significant damage to nearby local communities and thus generate environmental complaints. The construction company, responsible for compensating and resolving environmental complaints, suffers economic damages due to additional expenditures and schedule delays in construction projects. Meanwhile, the construction industry can stagnate from a broader perspective. Therefore, this study aimed to propose a framework for developing an automated management system which consists of two models for environmental complaints in construction projects: (i) the prediction model: a model for predicting environmental complaints based on factors related to environmental complaints; and (ii) the prevention model: a model for providing construction companies with the optimal prevention measure to effectively prevent environmental complaints according to the results of the prediction model. In addition, the algorithm for integrating the developed models into the management system in construction projects was proposed. Eventually, the application of the management system to construction projects can ensure the profitability of construction companies and mitigate damage from environmental pollutants to the nearby local community.

최근의 건축공사는 고층화되어 가는 추세이며 원가절감과 공기단축, 생산성 향상 등이 요구되고 건설자동화의 도입을 통한 총생애자동화시스템의 도입이 시급히 요구되는 추세이다. 이에 따라 본 연구에서는 초고층 빌딩 건축에 주로 사용되는 커튼월 공법과 제조업에서의 SCM기법, 최신의 RFID기법을 이용하여 초고층 건축물 커튼월의 자동화 관리시스템을 구축을 위한 방안을 제시하였다. SCM기법이란 생산에서 판매에 이르는 전단계의 과정을 연결, 관리하는 것을 의미하고 커튼월은 빌딩 건축에서 골조공사의 공기단축과 단순화를 위해 가장 많이 활용되는 건식공법으로 건설공사에서 가장 제조업에 가까운 형태의 공사로 볼 수 있다. 또한 RFID는 SCM의 구현방법으로 자재의 흐름과 생산프로세스, 그리고 정보관리 시스템의 도구로 사용되며 이들을 활용한 총생애자동화시스템은 생산과정 뿐만 아니라 사후관리 과정에도 효율적이며 높은 생산성과 경제성 향상에 기여한 것으로 기대된다.

이 연구에서는 기존의 수화열저감 공법에서 문제가 되었던 시공성, 공기, 공사비용 등의 효율성을 높이기 위해 새로운 매스 콘크리트의 온도균열 발생 저감시스템을 개발하였다. 이 시스템은 매스 콘크리트에 발생하는 온도균열을 제어하기 위해서 타설 예정 매스 콘크리트 구조체 중심부와 표면부에 온도센서를 매립한 후 콘크리트를 타설하고, 온도제어시스템을 통해 내 외부 온도차이가 균열제어 기준 온도를 초과하면 온도차를 그 이하가 될 수 있도록 자동으로 구조체 표면에 적정온도의 양생수를 공급하여 온도균열 발생을 제어하는 양생 자동화 시스템이다. 이 시스템의 타당성을 검토하기 위해서 mock-up 테스트를 실시하였으며, 이 시스템의 우수성을 확인할 수 있었다.

Recently automatic construction system is attended in construction domains because of the increase of aged workers and the shortage of the experienced. The research level of automatic construction system in Korea will soon attain to the stage of full automation like Japan, which is the highest level in the world. However, in the fully automated level, it is difficult for the automatic system to operate flexibly like the human in various work condition. In the result, the higher the level of automation in the system is, the less efficient the automatic system work in the site. So, it's necessary the development material design to compensate for the flexibility shortage of the system. Therefore, this study proposes the development process to material design suitable for automatic construction system using QFD technique.

Construction automation and robotics are being introduced as an efficient alternative to overcome troubles caused by lack of skilled labors. To accomplish effective automated construction system, design for automation(DFA) should be performed in parallel with the development of core technologies such as control and sensing of robots. In Korea, the development of robotic crane-based construction automation(RCA) system is progressing, and the research group has recently developed newly designed steel joint to improve the efficiency of the system. However, performance of the new system should be examined prior to its application on construction sites. Therefore, This study analyzed performance of the new steel frame focused on its constructibility by carrying out mock-up test. As a result, the steel frame satisfied the standards of allowable stress and deflection. It also enables to reduce the time for installation.

While researches related with construction automation have dramatically increased, a Robot-based Automatic Construction system (RCA system) has developed for high-rise buildings in Korea. At the aspect that wide adoption of the RCA system is dependent on economic efficiency comparing with a conventional method, feasibility study on the RCA system should be implemented. However, due to practical limitations, the RCA system has tested to a seven story building. Based on the test results, this study implements a cost/benefits analysis to a simulated forty story building in order to derive more reliable data on the RCA system's practicability.

A considerable number of construction disasters occur on pathways. Safety management is usually performed on construction sites to prevent accidents in activity areas. This means that the safety management level of hazards on pathways is relatively minimized. Many researchers have noted that hazard identification is fundamental to safety management. Thus, algorithms for helping safety managers to identify hazardous areas are developed using automated data collection technology. These algorithms primarily search for potential hazardous areas by comparing workers' location logs based on a real-time location system and optimal routes based on BIM. Potential hazardous areas are filtered by identified hazardous areas and activity areas. After that, safety managers are provided with information about potential hazardous areas and can establish proper safety countermeasures. This can help to improve safety on construction sites.
