This study suggested practical application of decision aid tool on re-evaluation of current buildings with a focus on a energy and economics evaluation methodology. In Europe, over forty percent of all construction activities are for retrofit. For efficient construction, various tools for re-evaluating existing buildings have been developed and are in use. Legislations of relevant laws and studies are actively initiated. In particular, EPIQR (Energy Performance Indoor environment Quality Retrofit), which was developed through the EU's Third and Fourth Framework Programs laid a foundation on a new concept-based decision aid tool for re-evaluation of existing buildings. As for actual applications, based on this, EPIQR+ was developed to be in line with a building maintenance guideline (SIA 469) and is actively applied to public buildings. This tool quantifies the degree of damages of existing buildings and suggests alternatives to users in energy (SIA 380/1) and economical perspectives. This study examined these preceding tools and suggested some trenchant approaching for more comprehensive and efficient use of re-evaluation tools in building maintenance.

Two important concepts in VE are "function" and "cost." Cost can be expressed quantitatively. Unlike cost, the function can only be expressed qualitatively. Thus, to accurately evaluate the performance in VE analysis, it is required that the functional aspect should be considered a qualitative one. This study suggests a procedure of function oriented evaluation which can evaluate function enhancement of a VE proposal more logically and objectively. To conduct this study, problems were induced via case analysis, and solutions were found. In addition, the existing simple evaluation procedures were corrected, and a function enhancement evaluation procedure via function classification was suggested. For function classification, the use of the concepts, which were "intended function" and "additionally obtained function," was suggested. Function oriented evaluation procedure to VE proposals which is suggested in this study is expected to be a great help in treating valuable functions through VE job plan.

The present Korean laws related to anti-corruption are not effective in preventing corruptions[1]. In this context, the purpose of this study is to build the proactive anti-corruption operating system that has the function to prevent corruptions from occurring in the contract and procurement sector of Korean public construction projects. The proactive anticorruption operating system consists of four parts ; developing integrity performance manual(IPM), making integrity performance plan(IPP), practicing IPP, and integrity performance evaluation(IPE). By analyzing various kinds of audits and relevant laws and interviewing with government officials and staff in construction companies, the causes and stereotypes of corruptions and the concept, role, and guide of IPM, IPP, and IPE are provided in this paper.

2000년 이후 국제적 건설시장의 이례적인 침체기가 지속됨에 따라 글로벌 무한경쟁체제 속에 국가경쟁력을 확보하기 위해서는 독보적인 기술력 보유와 더불어 선진화된 건설관리기법의 도입이 절실하게 요구되는 시점이다. 반면 국내 공공공사 입 낙찰제도는 1951년 최저가낙찰제 도입을 시작으로 그 동안 제도 개선이란 명분아래 수차례의 개정을 거듭해 왔지만 그때마다 정책적 이슈와 기대감에 빗대어 괄목할만한 성과를 가져다주지 못했음이 현실이다. 본 연구에서는 2007년 10월 도입이 결정된 최고가치 낙찰제도의 성공적인 국내정착 및 시행의 활성화를 위해 유럽, 미국, 일본 등 선진국의 성공사례를 분석하여 국내실정에 적합한 입찰자 평가체계를 구축하였고 실제 평가에서 활용이 용이한 평가 Tool을 고안하여 제시하였다. 본 연구는 선진국의 동일제도와 국내 유사제도 분석을 토대로 평가요소를 정립하였기에 제시되는 결과물들이 다소 일반적인 건설공사에 국한되는 한계점을 가지며 향후 본 연구에서 보다 발전하여 해당 사업유형에 적합한 특성화된 평가기준의 정립이 필요할 것으로 사료된다.

Since 'Act on Private Participation in Infrastructure' were changed in January 2005, BTL(Build-Transfer-Lease) projects of Private Participation in Infrastructure was introduced in the domestic construction market for the purpose of providing public facilities with the public. Selecting the most qualified Promoter should be considered discreetly in BTL projects because BTL projects is for projects with approximately thirty year project life cycle, plan, construction, operating, maintenance and obviously the success of the project totally depends on the capability and role of Promoter. However, score for cost is likely to influence selecting Promoter to take the project. Accordingly, low bid contract with too much competition could decrease the quality of the construction plan and operating plan. Thus, this study did preliminary research and documents on problems of evaluation criteria for selecting Promoter in BTL projects, and proposed improvement factors by doing questionnaire over specialists of each field.

Recently, major public owner and general contractors in Korea are actively preparing and improving BIM manuals and guidelines to effectively apply BIM technology in construction projects. These guideline has a purpose to define the scope of the applying BIM technology to each construction phase and to explain the minimum technology guidance required for the initial stage. In situations where BIM data are to be submitted within a limited time and cost at the design stage, a BIM data preparing process should be carried out in advance to meet the BIM interoperability between the pre and post of construction precess. In this research, we propose the scope of the BIM guidelines to meet and to be considered for the BIM based review of constructability and economic evaluation of Apartment.

In this study, the change of critical elements of the design evaluation was investigated during two decades at the architectural competition which was held nationwide in Germany. Specifically, the periods of investigation span both from July 1989 to June 1990 and from July 2009 to June 2010. The results of the analysis show that the cost of construction, the maintenance cost, the design of facade and the energy conservation are being magnified for the new important elements. The images of buildings and the economic aspects are meant to be high. The frequency of the critical elements for interior spaces is approximately two times more important than those for the forms and outdoor spaces. Overall, many juries of the architectural competition in Germany were interested in the elements for interior spaces. The field of function accounts for roughly the half of four basic architectural fields such as function, others, aesthetic and construction fields. The critical elements are required persistently such as context, Circulation, organization of space, form, landscape and outdoor space design, arrangement of building, cost of construction, function, design of facade, location of main entrance. These items are regarded as the most important elements of the design evaluation at the competition. Knowing the change of critical elements of the design evaluation, we can understand the trend of architecture in Germany. The results of this study can be applied in Korea to develop the critical elements of design.

A structural safety evaluation was conducted for the stabbing system for the pre-piling jacket substructure currently being developed in South Korea, considering pile construction errors due to its lateral movement that may occur during construction in the ocean. Based on (1) the maximum stress generated by the stabbing system, (2) the maximum rotational displacement of the guide cone, and (3) the maximum stress generated by the horizontal hydraulic pressure cylinder, the structural safety of the stabbing system was examined under the initial loading condition and three possible load combinations during its construction. In order to evaluate the structural safety of the stabbing system, a concept of stress safety factor (= Yield stress / Max. Von-Mises stress) was used. It was found that the stabbing system considered in this study has a sufficient margin of safety.
