New and Renewable eco-friendly energy technique can be to enable rational use of resources, as well as securing economic efficiency. Therefore, most of the public facilities must apply eco-friendly energy systems. In this study was applied the solar light energy system to the construction projects. As a result, the proposed system was implemented various effect such as the power cost savings in public facilities. In addition to, the proposed system was improved functional aspects such as improving space utilization.

This paper studies on the benefit evaluation of urban railway construction project. We compares Korean Method with Japanese in calculating the generalized cost(GC) of a trip. In Japan, the disadvantage of transferring to another mode or line is included to calculate GC of trip. And environmental effects are contained directly as rail construction benefit. But in Korea, inconvenience of transferring facilities like stairways and passageway for riding a subway is not accounted to analyse benefit. As a result, there is a little investigate to improve and overcoming the inconvenience facilities of transfer, access, and egress. So, we suggest the containing the disadvantage measure of transferring facilities when subway riderships are forecasted. That will be reduced tile capital size of subway.

Among the Barrier Free (BF) certification evaluation items for public facilities, at which position the standard for the effective height of the stair railing handle should be calculated is not clearly determined. Because of this, not only the evaluation standards of the certification authority and the evaluation committee are different, but disputes are occurring between the ordering organization, the design company, and the construction company. Therefore, the stair railing installation standard laws for public facilities were analyzed and through a case study of institutions that obtained the BF certification, problems were analyzed. The results of problem analysis reveal the following. 1) The standards of the Ministry of Health and Welfare and the Ministry of Land, Infrastructure, and Transport were different. 2) The effective height calculation standard was ambiguous, and disputes occurred frequently. To solve this problem, we proposed improvement plans for calculating the height of the stair railing that can comply with laws while ensuring safety.

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.

As nation and society progresses, urban ground facilities and their management system get more complicated and the cost and effort to control the system efficiently grows exponentially. This study suggests to the deployment method of a sensor node by Wireless Sensor Network for controling the Urban Ground Facilities of National Facilities. First, we achieve the management facilities and method using the first analysis and then make the coverage of sensing and then set up the Sensor Node in Urban Ground Facilities. Second, we propose the solution way of repetition by the second analysis. And, we embody the GIS program by Digital Map and this method, we improve the reality by overlapping an aerial photo. Also we make an experience on the sensor node allocation using making program. we can remove the repetition sensor node about 50%, and we can confirm that the sensor nodes are evenly distributed on the road.

Recently, expansion of urban and social infrastructures is planned to go through the transfer of military facilities or crossing the infrastructures via underground tunnels. However, when crossing facilities such as ammunition and explosive storages, a high level of safety assessment is required to prevent an accidental explosion of ground ammunition. In this study, a case study was conducted to evaluate the effect of blasting for the construction of tunnel on the ground ammunition facilities. The design section of Sinansan train operated by the Korea Railroad Authority with agreement of the Ministry of National Defense was selected. For the purpose of this study, the vibration velocity due to explosion was predicted by using GTS-NX, a numerical analysis program. Through literature review, it was confirmed that the vibration velocity of 0.2cm/sec can be a safety evaluation standard. These safety evaluation indicators and procedures used in this study can be utilized as an index of safety evaluation in the planning of social infrastructures that cross the ammunition facilities in the future.

The purpose of this paper is to evaluate environmental friendliness for facilities of national park to improve naturalness of national park. We have evaluated environmental friendliness of the facilities in Chirisan national park in terms of resource conservation and environmental integration, which are consisted of 9 and 8 evaluation indicators, respectively. Environmental friendliness of the small facilities was not good due to not using locally obtained materials and natural material, and that of large and complex facilities was bad in the field of excessive damage during construction, inadequate maintenance, use of natural material, locally obtained material, environmental integration with surroundings. In evaluating environmental attributes, new facilities is better than the older ones. The small facilities appeared to be worse than those of the complex, and the large facilities are the worst in terms of environmental friendliness. In general, environmental friendliness turned out to be lower in the light of the facilities in the clustered area than those of the facilities of the other area. In the future, It is required that criteria for evaluating environmental friendliness of natural park facilities is established.

The Ministry of Education and Human Resource Development has implemented the Construction Cost Saving Policy since 1998. The National Universities and Regional Education Committee have been required to follow the details of the Policy in constructing educational facilities in their jurisdiction. While the Policy has positive effect on construction cost saving of the entities, it has been criticized from the beginning of the Policy implementation because of its negative impact on project quality, education quality, trust in the public sector construction business, and solvent operation of the private construction companies which build the educational facilities in the entities. The research aims at investigating the pitfalls of the Policy and suggesting more reasonable approaches that can satisfy both the governmental entities and the private companies.

In this paper, The investment prioritization model was investigated for keeping the service level of mooring facilities more than the target level of management with a limited budget in the right time. Network level prioritization criteria of the national scale was developed to take into criteria index and quantitative evaluation, management authority's opinion. Delphi method was conducted maintenance exports of mooring facilities over twice for verifying the validity and adequacy. In order to improve the objectivity of criteria, the criteria for evaluating the utilization of port facilities is presented form yearly facility traffic/facility's length, the result of the analysis of facility traffic data. The investment prioritization criteria of mooring facilities is expected to be utilized for more efficient and national budget distribution applied to the maintenance budget plan of nationwide.
