The converted accident rates that included in Pre-Qualification (PQ) are to evaluate the results of accidents which have occurred. Therefore, it is demanded the development of proactive evaluation contents to evaluate the safety management activities and efforts on construction companies. The purpose of this study is to provide basic data for the establishment of proactive evaluation contents at public construction project in Korea through the collected and analyzed the PQ documentation applied by public agencies in Los Angeles, USA. The results indicated that diverse reactive safety evaluations are implemented to examine accidents which occurred in past projects such as occupational health insurance, regulation violation. And also, when the accidents occurred, it is evaluated the proactive safety management actions such as safety education, accident prevention programs, and safety management plans are reflected on the evaluation. Thus, if proactive safety related evaluation contents are established and reflected in PQ examinations together with diverse existing reactive safety evaluations considering converted accident rates, not only the existing function of converted accident rates can be reinforced but also businesses' active safety management activities can be induced and decreases in the construction industry's accident rate can be expected.

While a detailed cost estimation utilizes the comprehensive quantity information obtained from a complete drawing and specification, an approximate cost estimation heavily relies on the subjective decisions. This phenomenon is because the approximate estimation is usually conducted in early stage of the construction phase where the drawing and specification are not available. This study developed a roadway construction cost estimation system which enables users to estimate the approximated cost of the project in early stage. The system identifies the variation of the construction costs due to the road route change using a cased based reasoning(CBR) method. Overall the system is expected to improves the accuracy and effectiveness of the estimation process, because it would provide users with increased accessability and consistent results in early stage of the project which leaded to the increased work transparency.

As construction projects are getting larger, more complex and specialized, the size and scale of the structures are increasing and large-scale projects with multiple participants involved have continuously been ordered. Due to the nature of a large-scale construction project, when there are interferences and conflicts in process, schedule and area among project participants, the project requires more time and efforts to resolve the issues as it progresses further. This study suggests the interface management model that is time-saving and physically beneficial in solving interface issues based on case study. This study provides a practical management model including the organization of interface consultative group, checklist preparation, LIST management and PMIS application, which will be useful for the construction sites seeking effective know-how to manage design interferences and changes.

Idea creation is the most important step in the overall value engineering (VE) process. Usually the activity is done mostly relying on the experience and knowledge of the experts in the VE team. A more organized approach is needed to find the chance of design improvement during a VE workshop. This study presents an organized approach to increasing the chance of idea creation during the VE workshop. The concept of conflict resolution in TRIZ (Theory of Inventive Problem Solving) is applied to understand the problem area during design improvement. The technical parameters were identified in the problem area to explain the conflicts in design improvement. These technical parameters were used to assist problem solving and improve design functions. A case study was done on a temporary construction operation, and demonstrated that the organized idea creation can help improve the design value of the temporary construction operation.

Focusing on repetitive works of construction, many research have been conducted about application of the learning curve effect. However, it is still controversial, especially on the high-rise project, since the productivity improvement from the learning curve effects are hard to prove. In the previous research, applicability of the learning curve was mainly derived from the labor productivity data. Although the research were based on the real data, they merely concentrated on the simple conclusion that the labor productivity had improved or not, instead of the process interpretation. Therefore, the purpose of this research is to analyze the influence factors of the learning curve effect in high-rise projects and elucidate the offset factors of the effect. Based on these factors, a model for estimating the labor productivity containing the concept of process learning is suggested. Through our research, traditional learning curve theory could be compensated and re-established with having more appropriateness for high-rise projects.

Evacuation process has been considered as one of the most important elements to be managed in public facilities. Although the importance is highlighted through numerous literatures, disaster evacuation planning, particularly fire accidents, faces a number of human behavior related limitations for a similar application to different types of facilities/occupants. To overcome the obstacles including complexity in human behaviors, a number of simulation techniques with limited consideration on human behaviors are utilized to predict foreseeable problems in evacuation process. Therefore, this research aims to propose system dynamics models incorporating human behaviors considering different types of occupants under disaster evacuation events. Analysis on emergent human behaviors such as group forming and interactions under urgent situation are conducted based on the main stream theories in social science field. The results suggest the influences of human behavior factors including cooperative intention, information sharing, and mobility change to evacuation behavior. The implications are expected to provide safety consideration at planning/designing phase of buildings and help facility safety managers for evacuation planning with more realistic management approaches.

In the mixed-use development program, several conflicts occur due to the characteristics of construction program, such as large-scale, variety of stakeholders, long periods of time, etc. In particular, since the characteristics of the construction program having various complex projects lead to different requirements depending on stakeholders, it is crucial to plan the appropriate type and size of facilities. Therefore, it is necessary to derive solutions suitable for the needs of owner by conducting VE in the planning phase. In this study, a multi-dimensional quality model is developed to present proper facilities necessary for the construction program by clearly identifying the owner's requirements in performing VE in the planning phase. Through the development of the multi-dimensional quality model, the characteristics distribution of 15 major facilities by 12 performance indicators for mixed-use development programs is presented. The deduction method of appropriate facilities based on the requirements of owner and the multi-dimensional synthesis method among the performance indicators are also suggested. This study is significant as a basic research for the application of VE in the planning phase of construction program. It is expected that the multi-dimensional quality model proposed in this study could facilitate presentation and review of appropriate facilities based on the analysis of requirements of various stakeholders in the early stage of the construction program.

Construction industry is broadly agreed as one of the most important sectors of any economy around the world. In this paper, time series data of Korean construction industry and Korean economy are examined. The Bon's proposition will be inspected for Korean context using both cross-sectional and longitudinal analyses. The analysis of the longer than four decades national account statistic of the Korean macro economy verify Bon's proposition of an inverted U-shaped relationships. The verified U-shaped relationships for Korean context exist not only in terms of the construction share in total GDP but also in terms of total construction volume as an economy develops from LDC to NIC and then to AIC eventually with time. The results of the thesis show that the contribution towards the macro economy has varied across different stages of development.

Post-evaluation system reflects the results of performing a public construction project in the future similar public construction projects to be utilized in the planning. However, the current system simply compares the expected values, such as demand, B/C ratio, cost of construction, construction period, with the actual values after the completion of construction. In addition, most public owner does not actively conduct the post-construction evaluation tasks, so that the evaluation results has not been returned to early stage of a construction project. In this study, status of the post-construction evaluation system is investigated by a survey of the public owner and the construction project evaluation system of the United States and Japan was analyzed. This paper presents the improvement scheme of utilization of the results of the post-construction evaluation system. Through improving the post-construction evaluation system, it is expected that public agencies would easily utilize the post-construction evaluation.

A typical construction project involves participation of various parties including clients, contractors, architects, and engineers for its successful completion, and yet has intrinsic differences of interests among the participants during the project execution period. A construction management (CM) services's role is then to resolve these differences of interests among the participants during the project execution, and lead the projects to its successful completion while representing the clients' demands and interests. The use of building information modeling (BIM) is increasing recently among construction projects, and those CM service companies are experiencing difficulties applying BIM. This is because the use of BIM in construction projects suggests a quite new set of operational paradigm. The purpose of this paper is then to review the recent cases of projects which used BIM; to analyze the these projects' processes; to reengineer the design phase process based on the lessons learned from recent BIM application; and to suggest a modified design phase process model that could improve the use of BIM and related coordination operations.
