  • Construction productivity is a key factor for efficiency evaluation of construction work process, project performance measurement, and basic data of work plan in construction industry. However, although construction productivity is important in construction industry, gathering methodology and analyzing methodology of productivity data are not well-organized therefore productivity data is not utilized in the construction industry The purpose of this study is to develop productivity prediction system using data mining technology based on activities and to suggest frameworks about productivity data collection, accumulation.

  • Productivity is important to evaluate an efficiency of performed work and organization in construction industry. The productivity should be defined as activity level rather than macro level in order to effectively use productivity data and manage a project. The primary objective of this study is to develop a construction productivity management system using data warehouse, OLAP and data mining technologies which enables to easily accumulate the construction productivity data and perform multi layer analysis. Finally, it is anticipated that the effective use of the developed system would be able to measure the result of project and make a plan of the similar project with reliability.

  • In the previous comparative studies of international competitiveness conducted before 2003, Korean construction productivity had been estimated to be lower (or poor) than that of developed countries such as US, UK, and Japan. However, the amount of international contracts Korean has won increased substantially, and Korean construction has progressed with creating two skyscrapers such as Petronas Tower and Burj Dubai. At this point we need to reevaluate what we are capable of. In this paper, we evaluated international competitiveness of our construction industry comparing to advanced countries by analyzing labor productivity. For evaluating construction competitiveness we measured labor productivity using the value of construction work in US dollar per hour based on domestic and foreign statistical data and analyzing completion days per a story and the ratio of underground floors to ground floors of buildings in Korea and Japan. As a result, although our construction productivity is not yet competitive with the US and Japan yet, we excel the UK.

  • Activity-based productivity data can be used as an significant reference in many areas of project management such as performance evaluation and project planning. However, the existence of various factors influencing construction productivity makes it difficult to collect and analyze the productivity data. In the most of the domestic construction sites, there is no systematic method to collect and analyze the productivity data along with information on influencing factors; it is common to heavily rely on experience and intuition of field managers when dealing with construction productivity data. Therefore it is necessary to develop a management system for collecting and utilizing the productivity data as well as the factors influencing construction productivity. The main objective of this research is to define the construction productivity and its influencing factors at the activity level. In addition, methodologies on how to analyze the productivity data and to estimate productivity of future projects are proposed.

  • Productivity is one of the very important index that measures efficiency of production activities in industry, enterprises and the building industry as well. None the less, the concept of construction productivity is not so clear that productivity management in the building industry have been performed by experience or intuition, productivity related data have not been analyzed through effective productivity management, because structured definition and classification of factors influencing construction productivity did not exist so that it has not been known what information explain each of them. In order to solve this problem, at first construction productivity and factors influencing construction productivity are defined and classified into three groups; (1)Project factors influencing construction productivity (2)Management factors influencing construction productivity (3)Activity factors influencing construction productivity. To find out relation between construction productivity and factors influencing construction productivity, a questionnaire survey for construction managers in the building industry has been conducted.

  • Proper management of construction productivity is one of the main drivers of project success. This research focuses on the development of a construction productivity analysis system based on Web and OLAP in order to effectively manage construction productivity. Throughout the research effort, a construction productivity analysis system was modeled using IDEFO & ERD techniques and was deployed on the WWW(World Wide Web). Based on the system modeling, this research studies the methodology for system development of construction productivity that can consult the decision of managers on job site.

  • 건설 공사에 있어서 생산성은 중요한 의미를 가지고 있다. 하지만 국내 건설현장에서의 샌산성에 대한 인식은 상당히 낮은 것으로 보이며, 건설현장에서의 생산성에 대한 인식변화 및 활성화를 위한 토대를 마련하는 연구는 드물었다고 판단된다. 기존의 생산성 측정에는 많은 방법들이 사용되어지고 있으며, 이러한 측정 기법들은 생산성 측정에 있어서 결과만을 모니터링하고 보다 나은 결과물을 획득하는데 그 목적이 있어왔다. 하지만, 해외의 경우 건설 생산성의 초기투입단계에서의 관리와 노력을 통해 생산성을 향상시키고자 하고 있다. 따라서 본 연구에서는 린 건설에 관련하여 기존의 생산성 측정보다 쉽게 생산성을 측정할수 있고 빠른 피드백을 얻을 수 있는 percent plan complete(PPC)의 기법을 적용한 새로운 생산성 관리가 어떠한 프로세스로 이루어지고 있는지 분석하고 국내 건설 현장의 새로운 생산성 관리 시스템 구축의 기반을 마련코자 한다. PPC는 계획되어진 작업계획의 신뢰성과 생산성을 측정 가능토록 해주며, 린 시스템의 적용이 필주적으로 수반되어야 한다. PPC 측정 후 작업이 실패되었을 경우 그 이유를 파악하고 원인 분석이 이루어져야 한다. 그렇게 된다면 어떤 공정에 대한 결과를 평가할 수 있고 그 과정에서 미래에 발생할수 있는 작업 실패를 예방할 수 있다.

  • We study the RFID network system in a construction site, and study the connection method between the RFID network system and the integrated information system of construction material. Moreover, we developed a prototype of the construction site RFID server for the management of construction materials and performed the pilot application in a construction site. Through the pilot application, it was known that the proposed RFID network system can be more usefully applied in the construction sites. The results of the pilot application show that the RFID network system is faster, more accurate, and more reliable than the existing system of information management and achieves improvement in construction productivity.
