본 연구는 공공도서관 건립 타당성조사보고서에 있어서 경제적 타당성 접근방법과 정책적, 기술적 타당성 접근방법을 비교$\cdot$분석하고 문제점을 구명하였다. 경제적 타당성 분석에서 사용된 비용편익분석은 편익추정과 할인율 적용에 문제가 있는 것으로 나타났으며 정책적, 기술적 타당성 분석은 건립이 확정된 사업을 합리화하는 수단으로 잘못 활용될 수 있는 문제가 나타났다. 본 연구의 결과는 공공도서관 건립을 계획중인 관련기관에서 타당성조사를 준비하는데 유용한 자료가 될 것으로 기대한다.

Recently, plastic panels have replaced plywood panels in formwork. Since, plastic panels have excellent workability, can be re-used for over 50 times, and are lighter than Plywood. This paper aims to perform an economic analysis of plastic panels by considering unit cost, cost of form oil and the number of use. The results showed that plastic panels are more economical than plywood according to an increase in area of construction site. This result of the study can be used as a basic data for the selection of plastic formwork panels.

In this study, the remodeling of the insulation for the study of economic evaluation to find out. Targeting first Hyomin Domitory in Dong-Eui University, the purpose of the study is to carry out insulation work to conform to the strengthening of legal insulation standards. Studies in the way of insulation construction surveys of students who after living through the Survey. Exterior walls and windows with a comparative analysis of the thermal transmittance insulation performance is calculated according to the annual heating costs. The study is about 108 years after the investment is recovered through the break-even point was to know. Resolve residents' complaints, the gap wind reduction, reduction of environmental pollution and other problems solved.

It is difficult for a superintendent or an operator of building service systems and equipment to decide the reasonable time for management of himself due to the shortage of his specialty for repair or replacement of a part of or whole equipment. But The reliable life expectancies for various building service equipment have not been prepared yet. This study shows the difference of optimal economic life and the decrease of running cost and energy consumption according to management level of the building equipment by the LCC analysis. The numerical model for building HVAC system was composed and analyses were performed for several parameters with management.

In this study, In order to apply the U-flanged truss hybrid beam to the actual construction site, the structural design of the basic module of the middle and low-rise neighborhood living facilities was performed according to the Korea Design Standard, and the construction cost and construction period were compared with the traditional reinforced concrete structure system. As a result of analyzing the construction cost for the basic module, if the U-flanged truss hybrid beam and D-Deck slab system are used, the construction cost can be reduced by 86% compared to the traditional reinforced concrete structure system. In addition, as a result of analyzing the construction period for a floor area of 1,000m², using the U-flanged truss hybrid beam and D-Deck slab system can save 2.0days in construction period compared to the traditional reinforced concrete structure system. Therefore, the U-flange truss hybrid beam can secure sufficient economic feasibility compared to the existing reinforced concrete method in terms of cost reduction and shortening of construction period.

Owning to rapid infrastructure development, Asia is experiencing dramatic economic growth. There are not a few cases in which, however, economic growth is achieved by increasing the external diseconomy. Pursuit of sustainable development is one of the most important issues for mankind. Under the post-industrial capitalism society, however, there seems a big risk of increase in the external diseconomy worldwide. The objectives of this manuscript are to discuss importance of risk management of construction practice in present and future. Regarding the latter, a particular attempt is made to discuss how project risk communication should be done to reduce the external diseconomy. Presently, one of the important issues in implementation of infrastructure projects is practice of risk management to properly manage time, cost, quality, and safety: mainly maximization of internal economy. Multi-party risk and uncertainty management process (MRUMP) is one of tolls to assist it. The idea on MRUMP can be used to reduce the external diseconomy through identifying, sharing, and tuning people's rhythms.

최근 재건축 및 재개발의 활성화, 대규모 택지개발에 의한 신도시 건설, 사회기반시설 확충 등의 증가로 건설폐기물이 급증하고 있다. 급증하는 건설폐기물 문제를 해결하기 위해 정부는 2003년 12월에 "건설폐기물의 재활용 촉진에 관한 법률"을 제정하였다. 이 법에 의하면 건설폐기물은 중간처리업체뿐만 아니라 건설공사현장에서 배출자가 직접 재활용할 수 있도록 규정하고 있다. 그러나 현재 대다수의 건설폐기물은 중간처리업체를 통하여 재활용되고 있을 뿐, 건설공사현장에서 배출자에 의해 직접 재활용되는 사례는 찾기 어려운 실정이다. 현장재활용을 어렵게 하는 가장 큰 원인은 현장재활용에 따른 경제적 효과의 불투명성이다. 본 연구에서는 건설폐기물의 발생 및 처리과정, 건설폐기물의 재활용 실태, 현장재활용 절차 및 과정 등을 조사 ${\cdot}$ 분석하고, 대규모 택지개발사업에서 폐콘크리트를 현장재활용하고 있는 사례를 통하여 경제성을 분석함으로써 현장재활용의 타당성 여부를 규명하였다. 본 연구결과는 현장재활용을 활성화하기 위한 정책수립 및 현장재활용 여부를 판단하는 기초 자료로 활용될 수 있을 것이다.

Generally, as corrosive protection processing of a steel structure, zinc galvanizing and heavy duty coating paint are applied. However, zinc galvanizing has the difficulty of restriction of a size, or on-site construction. Moreover, heavy duty coating paint has a problem with many administrative and maintenance expenses with short problem of adhesion, corrosion generating of a damage portion, and maintenance management cycle. In this study, a salt water spray test, CASS test, and the electrochemistry examination were carried out for the thermal metal spray method of construction for corrosive protection performance evaluation. Moreover, the corrosive protection life of a thermal metal spray method of construction was quantitatively calculated on the basis of this experiment. in consideration of LCC, the economical efficiency of a general corrosive protection method of construction and a thermal metal corrosive protection method of construction was compared. Consequently, although initial construction expense was estimated 16 to $30\%$ high, as for a thermal metal spray method of construction, it turns out that the administrative and maintenance expenses for 100 years became cheap 9.3 to 13 or more times.
