  • Construction Performance measurement and management has been interested by construction practitioners. However, current construction project management practices are related to short-term improvement plans rather than long-term and systematic approaches based upon performance analysis. AR a result, there is a need for developing of a collaborative plan over project life cycle. Therefore, this paper reviews extensive literature and proposes the construction performance estimating model using a system dynamics. The paper proposes casual maps for planning, design, procurement, and construction phases. Each casual map includes all performance indicators and factors that impact on performance directly or indirectly. These casual maps that were developed by system thinking will enhance the understanding of the relationships among performances and factors. After further data gathering, these models can be used to estimate construction performance and eventually these will save project costs and shorten project schedule.

  • Recently, the roles of the construction engineers become more important in all phases of construction project life cycle. Construction engineers' capabilities is one of the key factors to accomplish construction project objectives. After acquiring basic Knowledge and skills in colleges, the construction engineers have opportunities to develop their abilities through continuous education provided by companies, associations, colleges, and so on. The current eduction system is not sufficient enough to assist engineers to develop their potentials. The construction professionals training system that help career development, career management, education and training is need to raise excellent engineers in a long term perspective. In order to investigate the necessity and the element in the career development support, I perfromed the perception about the career deveolopment by doning question investigation.

  • Lack of client involvement in construction of public projects has been identified as the main cause of many operational problems. Clients need to perform their roles and responsibilities effectively and efficiently at the right time and through the use of correct methods in order to have the optimum involvement required during all the construction project phases, namely, the planning, design, construction, handover, and operation and maintenance phase. This paper investigates the influence of clients' individual factors on their involvement in construction project delivery. A questionnaire survey was distributed to various government agencies of the Kingdom of Saudi Arabia (KSA). Explanatory Factory Analysis was performed to group nineteen individual factors. The factor analysis result suggests that the individual factors that can involve clients' involvement in construction projects can be grouped into five, which are: adequacy of knowledge and experience for decision making in the early stage of design; ability to communicate clearly; job satisfaction; personal skills; and expertise in design and construction.

  • 전설프로젝트 데이터의 통한적 운용은 건설 프로젝트의 효율적인 관il엔 있어 필수적이다. 최근 데이터 호환성(interoperability)에 기초한 통합방법론으로서 IFC(Industry Foundation Classes)가 제안되었고, IFC에 기초한 시스템 통합의 예가 나타나고 있다. 데이터 호환성(interoperability)의 개념은 각 시스템의 독립성을 보존하면서 시스템의 통합을 전개할 수 있도록, 건설객체를 시스템간의 데이터 공유 프로토콜로써 제시한다. 본 연구에서는 이 데이터 호환성의 기본 개념에 입각하되, 실제 프로세스의 업무범위와 절차를 고려한 단계적인 시스템 개발전략을 제시한다. 이는 실제 업무를 지원하는 정보시스템의 관점보다는 IFC에 의한 시스템 통합에 더 큰 비중을 두고 개발하는 경향에 대한 문제제기이며 그 극복방안이다. 즉, IFC 모델의 데이터 호환성 개념을 응용하여 실제 업무범위와 절차에 적합하게 배치되고 활용되어야 함에도 탁구하고, IFC의 형태에 치중한 결과 실제의 업무를 지원하지 못하는 시스템개발 경향을 극복하고자 한다.

  • 본 연구에서는 건설공사에서 발생할 수 있는 리스크 요인의 효율적 잔치론 위해 리스크관리 절차에 대해서 중점 검토하여 국내 실정에 가장 적합한 세부 리스크관리 절차를 제시하기 인한 모형을 개발한다. 본 연구에서 제시하는 건설공사 리스크관리 모형(CRMM, Construction Risk Management Model)은 리스크관리를 위해 리스크관리 준비단계부터 리스크 요인의 확인, 분석, 대응 및 관리단계의 총괄적인 작업을 수행하기 위한 모형으로 구축한다. CRMM에서는 리스크관리를 위한 3단계 모형(리스크 확인 모형, 리스크 분서 모형, 리스크 대응 모형) 구성으로 리스크관리 단계별 모형을 구축한다. 구축된 단계별 모형은 전산화의 기본 구성절차와 모듈 구성의 초기 자료로 사용되며, 기존 리스크관리의 세분화되고 전문화된 절차로 사용될 수 있다.

  • In the present study, annoyance caused by diverse construction noises was evaluated through surveys. A survey with a total of 110 construction workers was carried out to investigate annoyance from construction noises at different construction phases. The most effective item of adverse by construction noise was annoyance and the most annoyed construction stage was destruction construction. There were high correlation between work performance and work safety as well as work safety and speech interference. Participant's noise sensitivity were significant between low and high group at work performance, work safety, speech interference.

  • Ecological Engineering (EE) refers to all sustainable engineering that can reduce damage to ecosystems and that adopts ecology as a base and safety as an orientation in order to implement conservation of biodiversity and sustainable development. In short, EE attempts to safeguard the ecological environment while any essential construction projects proceed. EE encompasses many fields, including construction skills, ecosystem preservation, landscape, and even related cultures and so on. Such variety results in greater complexity of construction, and, consequently, indirectly increases the difficulty of construction quality control. The objective of our research is to explore a promising model for EE via an extensive literature survey. This model includes three principal stages: plan-design, construction, and maintenance, along with individual accompanying phases concerned with quality control and vital management. In this article, a river restoration example is adopted to describe in detail the critical points of quality control in the three stages (plan-design, construction, and maintenance) of the construction life cycle. This study proposes an integrated structure for quality management of EE to guarantee its quality and to enhance its core applications in order to achieve long-lasting preservation of the environment.

  • On the construction area, Information Technology (IT) has been a considerably significant part over the all phases; plan, design, procurement, construction and post-construction. For example, CALS, CITIC, PMIS, FMS, BIM and etc, designed and applied for managing construction industry are already valuable to improve on the Construction Management (CM). To develop these management methods, lots of mixed-systems are studied and progressed so far. In this paper, more useful and efficient system modules are proposed through investigating PMIS cases implemented, especially medical projects, to improve into FMS on the post-construction. Because most PMIS on the construction phase is used not to continue as FMS, considerable cost and time is consumed to rebuild the system, even both systems have common modules. As these wastes are faced to design systems, the important modules on PMIS are derived and analyzed to apply to FMS to save time and cost on CM.

  • The sudden changes in the construction market and the progressively intensifying price wars have amplified the importance of the construction cost estimation in the initial and planning phases of construction projects. However the methodologies and process of estimating construction cost in the planning and design phase are not standardized in the domestic market, in contrast to the markets of more developed countries. Therefore this paper proposes a new approximate estimation model to be used from the initial stages of construction projects. This methodology that extracts, modifies and synthesizes comparable elements of previous cases. This will introduce the foundation for the implementation of systems with improved usability and applicability.
