This study aims to analyze the risk factors caused by object damage and third-party damage loss in actual bridge construction based on past insurance premium payment data from major domestic insurers for bridge construction projects, and develop a quantitative loss prediction model. For the development of quantitative bridge construction loss model, the dependent variable was selected as the loss ratio, and the independent variable adopted 1) Technical factors: superstructure type, foundation type, construction method, and bridge length 2) Natural hazards: flood anf Typhoon, 3) Project information: total construction duration, total cost and ranking. Among the selected independent variables, superstructure type, construction method, and project period were shown to affect the ratio of bridge construction losses, while superstructure, foundation, flood and ranking were shown to affect the ratio of the third-party losses.

Conflict in public construction projects has increased for the last decades. It not only entails enormous social and economic costs but also makes stakeholders suffer from unnecessary expense and time waste. This study defines the the conflict index for public construction projects based on news data, and calculates conflict index for representative past and current public construction projects that has been deepened conflicts at the national level. The result indicates that the major conflict issue of the 2nd Jeju Airport Project are the environment and location whereas that of the Gaduk New Airport Project are the safety, location and necessity. This approach is expected to enable construction project managers to manage conflicts quantitatively based on comparing with past cases.

The performance measurement of construction projects has traditionally been evaluated as a prerequisite for successful project completion. Considering this importance, the UK and the US are operating quantitative performance measurement systems for construction projects. However, in the case of Korea, there is a limit to the use of existing methods due to the limitation of data collection. Recently, in consideration of the domestic situation, research is being conducted to measure the quantitative performance of a project by using big data including progress and project attribute information. Therefore, this study aims to present the design direction of a performance monitoring system using Quality Function Deployment.

The urban renewal type redevelopment project is a project to improve the urban environment for the recovery of urban functions and revitalization of commercial districts in commercial and industrial areas. Urban regeneration projects are not progressing smoothly. The urban renewal type is not so for landowners, who require a high level of professional knowledge and experience to carry out smooth projects. In addition, the core part of business conflicts can be seen as the problem of management and disposal methods. Therefore, as landowners, etc. become the actual subjects, the public will take charge of project execution, but all development gains and losses will be attributed to the owner of the land, etc.

Building Information Modeling (BIM) comes to be implemented into architectural design, construction, and maintenance in Japan in order to convert design information thoughout a construction project. However, various problems are taking place in data transaction. It is not also clear about the role and the responsibility of the architects and the enginners in charge.There is a movement to establish a BIM manager as a general coordinator concerning BIM in Singapore and other countries, though it is not yet popular in Japan. This paper deals a BIM manager as a new profession in a construction project. The function and skills necessary to a BIM manager is analyzed, and the strategy of Japanese general contractors is discussed. General contractors from Japan are operating BIM in Singapore compatible with open system of supply chain. This style is different from the one in Japan even they belong to the same company. In this paper it is analyzed based on the survey in detail.

Building Information Modeling (BIM) is an effective decision-making platform that helps to save project cost and enhance quality of construction. By generating and linking a wide variety of objects data, BIM can be effectively utilized, and it should be ensured that object properties maintain consistency throughout the project period of design, estimates, construction, maintenance and repair. This study examined how to utilize BIM data in a construction project, by linking cost and schedule data in web environment, to better utilize the information and maintain consistency of the BIM information. To do so, the model integrated WBS data and CBS data, linked them with BIM model to realize 5D simulation in web environment. As a result, cost and schedule data could be simultaneously acquired, and object properties-cost, schedule, location-as well. These are expected to contribute to developing a BIM-based automatic data-processing system in web environment.

As construction project becomes big, PMIS has been progressed and developed as collaboration tool between project participants. But recently it has been transformed from collaboration function tool to one of formal systems, and used as a simple report or just database system. Many researches have been actively studying how to combine BIM to PMIS for solving the problem. There need transferability from PMIS to BIM, however, data size is getting big because of complexity in building size. Many users experience inconvenience in slow loading speed. Therefore, this study suggested an improvement method for high transferability by utilizing virtual technology of IT industry and analyses its suitability.

In construction work, there is often a difference between the estimated construction period and the actual construction period. Accordingly, the project may be delayed from the scheduled date, leading to huge losses due to problems such as increased costs during construction. In this way, it is important to calculate the appropriate construction period at the project planning stage in construction work. To solve this problem, we would like to study a model that will increase the accuracy of the scheduled construction period at the project planning stage. This study compared and analyzed linear regression, Lasso regression, Ridge regression among the types of regression analysis to select an appropriate construction period prediction model to secure an appropriate construction period at the project planning stage to reduce problems during construction.

Sustainable housing design can contribute to dramatically reduced energy usage and can be applied to all new building projects. This paper explores the potential in Korea of applying available energy efficient building technologies. The objective was to determine the degree of energy reduction that can easily be achieved in new building design. The pilot project is providing some prototypes with display units which incorporate principles of sustainable design and performance utilizing the eco-design objectives. This building challenges ingrained preconceptions about system designs for four energy saving levels(40%, 60%, 80% and zero energy) and exposes barriers to low energy buildings posed by new standards and guidelines.

이 연구는 다양한 목적을 가진 단위사업을 통합하여 포괄 보조하는 문화사업의 성과를 분석한 사례 연구이다. 문화도시 조성사업을 평가하는 성과지표가 마련되어 있지 않다는 점에서, 이 연구에서는 문화도시형 문화특화지역 조성사업을 사례로 삼아 사회적·문화적·경제적 효과를 고려한 산출성과-영향성과-효과성과 평가지표를 제안하고, 지표별 성과를 분석하였다. 이 연구에서 분석한 사례는 남원시 사업이다. 남원사업은 산출성과와 관련하여 문화적 사람과 문화적 콘텐츠를 발굴하고 육성한 성과가 크나, 사업의 지속가능성과 고도화라는 측면에서 아쉬움이 남았다. 효과성과에서는 단위사업보다 더 큰 성과를 보였다. 남원사업 효과를 단위사업인 문화시설 건립 및 문화이용권 사업과 비교 측정한 결과, 문화특화지역 조성사업이 문화시설 건립 및 문화이용권 사업보다 주민의 소득증가 효과가 더 큰 것으로 나타났다. 소득증가는 소비증가로 이어지기 때문에 소득증가 효과가 큰 사업유형이 산업 성장에 더 많은 영향을 준다. 이는 문화적 사람, 문화적 프로그램, 문화적 공간과 관련된 사업을 통합하여 포괄 보조하는 사업방식이 문화적 지역발전을 지속하는데 단위사업보다 더 효과적이라는 것을 의미한다.
