  • Interface management problems inherent in construction projects hamper their successful delivery. Therefore, this study aimed at determining the most important project interfaces in construction works in Nigeria in terms of most significant potential impacts, so that management attention are objectively focused on potential highest impacting project interfaces. From a review of literature, 28 project interfaces management issues were identified and categorized. Structured questionnaires were used to collect data concerning the impact (estimated losses to the project in terms of cost) and probability of occurrence of the identified interfaces. The interfaces were ranked using their computed Matrix Scores (MS). The results reveal that "project-workers interfaces problem manifested in use of inappropriate mixes" is the highest impacting. A ranking of the interface categories also reveal that the interfaces at the execution phase of a project (MS = 1226.79) are those that could result in the highest losses to the project.

  • Recently indoor air pollution caused by exposing hazardous chemicals (VOCs, formaldehyde) due to undiscriminated use of new construction materials and air-tightness to save energy is becoming a big issue. We have developed technologies to estimate the amounts of contaminants from constructions materials and method. We have further developed construction technologies to reduce and characterize these contaminants. The developed technologies were then refined to eliminate defects through considering field applicability.

  • This paper discusses cases of infrastructure asset management in the U.S., Canada, and Australia and investigates infrastructure management in Korea in order to set the direction for the asset management improvement. The definitions of infrastructure asset management from various entities are introduced and implementation framework and organizational structures are described. The investigation on Korean public asset management practices finds the strong and weak points and defines the requirements and considerations to further improve the current practices. This paper will assist adopting infrastructure asset management in Korea and provide guide for the infrastructure maintenance.

  • Drill and blast method has been most widely used in tunnel excavation, after NATM (New Austrian Tunneling Method) was introduced in 1983. The NATM method utilized mass of shotcrete to secure the bearing capacity of tunnels. Overbreak defined how much larger the actual excavation was than the planned. When it became larger, more shotcrete was required to fill in it Here, payline fixed allowable overbreak, referring to payable amounts of shotcrete. Since owner was not responsible for shotcrete exceeding payline, it was important to properly establish the standards for payline. Although the standards were provided in 'Poom-sam'(standardized quantity per unit), they did not properly reflect the actual conditions for excavation. Thus, this study reviewed existing domestic and foreign standards for overbreak, and estimated overbreak for each type of support using survey data, and finally provided the improvements on the current standards.

  • 모듈러 건축은 스마트 건설방법 중 하나로 건설산업 혁신을 위한 필수적인 공법이 되고 있다. 모듈러 건축의 스마트 건설 실현에 필요한 가장 기초적인 전제 조건 중 하나가 품질관리이며 이를 위해 3차원 스캐닝을 이용한 품질관리 방안에 대한 관심이 높다. 본 연구는 모듈러 건축 프로세스 단계별(공장제작, 운송, 현장시공) 주요 공사를 대상으로 IPA분석을 통해 3차원 스캐닝을 이용한 모듈러 건축물의 품질관리에 대한 현황을 분석하고 이를 개선하기 위한 방안을 제시하였다. 그 결과, 대부분의 항목에서 3차원 스캐닝 데이터 활용에 대한 필요성과 중요성이 높다는 것을 확인할 수 있었으며, 일부 현장 적용성이 낮은 항목들에 대해서는 추후 기술개발 및 적용성 개선이 필요한 것을 알 수 있었다. 본 연구결과는 향후 모듈러 건축 품질관리를 위한 첨단 시공 기술 적용에 대한 연구에 활용할 수 있다.

  • 최근 국내 건설 프로젝트 수행과정에서 발생하는 정보관리 기술의 고도화를 위해 IT기술을 활용한 건설 사업관리 정보시스템(Project Management Information System, PMIS)이 개발되어 활용되고 있다. 국내에서 개발된 PMIS는 국내 건설 프로젝트뿐만 아니라 국내 건설기업이 수행하는 일부 해외 프로젝트에도 제한적으로 적용되고 있다. 본 연구는 국내 기술로 개발된 PMIS를 미국건설IT 시장에 특화된 시스템으로 개발하는 것을 목적으로 수행되었다. 미국 건설 IT시장은 주로 미국 기반의 IT기업에 의해 개발된 제품들이 독과점으로 선점하고 있었으나, 최근 차별화된 기술 경쟁력 및 시장전략을 통해 시장을 확보해 나가는 기업이 증가하고 있다. 시스템 개발을 위한 선행연구로 국내와 해외에서 상용화된 시스템을 분석하였고, 미국 건설 프로젝트 수행 시 계약, 공정, 원가관리의 핵심요소를 분석하여 PMIS의 요구기능을 정립하였다. 이를 바탕으로 개발된 PMIS는 내부 전자결제 시스템을 포함한 문서관리 모듈과 실비정산 기반의 노무비 자동 산정 모듈, 진도관리 모듈을 통해 통합 사업비관리를 지원한다. 또한 개발된 시스템을 현지 건설 사업관리 전문가를 대상으로 설문조사를 실시하여 타당성을 검증하였다. 본 연구를 통해 개발된 PMIS는 미국 건설 산업에 특화된 시스템으로써 미국 건설 IT 시장 뿐 아니라, 해외 타수요처 적용 측면에서 점진적 확대를 기대한다.

  • Recently, the amount of the construction and demolition wastes has rapidly increased due to increasing construction projects. In the past, most of the construction and demolition wastes were buried in the ground of thrown away. Illegally, without any treatment, so various harmful environmental pollution problems were occurred. In this study, the domestic data on the amount of the construction and demolition wastes and the disposal methods were collection and analysed. Specially, the recycling and management systems of the construction and asphalt concrete wastes were studied. A new technology and necessary policy for recycling were suggested. In general, the industrial wastes were produced in the particular place, and the amount and the characteristics of the wastes able to be estimated by the studies on the treatment technology. And the investment of the facilities for the industrial wastes have been made continuously. But little attention has been relatively given to the treatment technology. And system for the construction and demolition wastes for the political support and facilitation on the proper treatment and the recycling, the necessary of information exchange system and the manifest system for treatment of waste on commission were recommended, and also devised methods to develope and support the recycling industry. In the future, the subject of study is going to carry out analysis of economic and market in making products.
