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.

Using integrated construction project data is necessary for efficient management of construction projects. Recently IFC(Industry Foundation Classes) are proposed as integration method based on interoperability and there have been several cases of system integration based on IFC. The concept of interoperability proposes the construction object as data sharing protocol between systems for system integration and independence of each system. This study proposes system development strategy by phases considering work scope and procedure of processes based on the concept of interoperability. This is proposed to overcome tendency of developing system which doesn't support real work processes as result of inclining to the format of IFC instead of properly using IFC's interoperability concept to real work scope and procedure.

Most construction companies recognize the necessity of risk management. The practical application, however, is not easy because of the absence of systematic procedure for risk management and the difficulty in objectification of subjective risk factors. This study suggests a systematic procedure and a models. In the first place for those researches, this study analyzes the present condition of risk management in the construction industry. The developed model can be used as a risk management tool that enables evaluation of construction risk factors by quantified method, and it provides project managers with the methods to prevent risk and to deal with potential risk factors in the planning and construction phases. The results of this study could be used as references for related researches because this study attempts to develop a systematic tool for risk management including risk identification, risk analysis. risk action phases.

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.
