The purpose of this study is to find what causes make public projects hold off, going beyond the planned deadline and budget. Using System Dynamics(SD) and their derivative Urban Dynamics(UD) models, it intends to analyze major feedback loops based on VENSIM and to simulate them with STELLA software, all of which are interrelated with various causes of project delay. To prevent or ameliorate project delay, first of all it advises to focus on endogenous delaying factors not exogenous ones. These factors either reinforce or balance certain loops in complex causal structure, In the case example on the Cremation Building Project in Cheongju, Residents’ participation demand make negotiation put off and delayed negotiation reinforces administrative-expediency planning in order to observe a time limit, on the other hand, once building consensus, it increase both the level of planning performance and public trust. In the meantime, the real planning process used to neglect residents opinions and manage public grievance only through compensation, he a result of simulation, visible fruit of negotiation in the initial phase seems to be not satisfactory owing to funds and time consumed, but after reaching an mutual agreement among stakeholders, planning performance is effective and strategic than administrative-expediency planning viewed in both financial and time angle. It proposes to devise specific tools schematizing project implementation. In order to upgrade the quality of project management, it recommends for planners to adopt key concepts based on SD/UD diagrams and causal loops, which would contribute to enriching Planning abbots.

Looking at current construction costs estimations of publicly declared public works, there are many instances where estimation criteria are ambiguous and doesn't imply the reality. Up to date, estimation criteria for calculating construction cost estimations are simply by unit area multiplication and stochastic construction cost estimation. However, possibility of making errors are high due to using uniform data that excludes each public work's specifications and environmental conditions. Further, on the aspect of cost management, there is certain limitation in the efficiency of cost management in order-placing stage and commencing-work stage; while efficient cost management and reduction of expenses are highly possible during initial stages of the project. In this respect, the paper adopts positive approach with regards to construction cost estimations of public works and draws common elements from calculation tables of the construction cost estimations from 3 completed domestic construction works; after which, the paper analyzes whether business exposition, construction guide and publicly-declared estimated construction costs that the orderer issued are calculated economically and properly; deducing problems in the process, the paper seeks to recommend rational calculation method on this.

2005년 1월 사회기반시설에 대한 민간투자법 개정으로 공공서비스시설을 국민들에게 제공할 수 있는 새로운 민간투자방식인 BTL민간투자사업(Build-Transfer-Lease)이 국내건설시장에 도입하게 되었다. BTL사업은 설계, 시공, 운영 및 유지관리까지 포함하여 최장 30여년 이상의 프로젝트 수명주기 전 과정을 대상으로 하는 포괄적인 형태의 사업방식으로 사업자의 역할과 수행능력 여하에 따라 사업의 성패가 좌우됨으로 최적 사업시행자의 선정이 중요하다 그러나 BTL사업의 사업시행자 선정시 가격평가점수에 따라 많은 영향을 받아 최저가 투찰로 인하여 우수한 기술능력을 갖춘 사업시행자보다 최저가격을 제안한 사업시행자가 선정 될 수 있는 가능성이 높아 건설계획 운영계획 유지관리측면 등에서 품질수준이 저하될 우려가 있는 것으로 조사되었다. 따라서 본 연구는 BTL사업의 사업시행자 선정을 위한 평가기준의 문제점을 분석하고 전문가 설문조사를 통하여 개선방향을 모색하여 평가기준 개선방안을 제안하였다.

Vilhelm Wohlert is the Danish architect who designed Louisiana Museum of Modern Art near Copenhagen. Because of Louisiana Museum's popularity, Vilhelm Wohlert's name was started to be aware since 1990s. Although he is a well-known architect in Denmark, unfortunately his name is unknown in other countries. He designed various design projects from small scale furniture design to large scale museum and public projects. There are three programmatic categories in his architecture: exhibition programs including Louisiana Museum, residential program including private houses, and public programs including churches and schools. This thesis focuses on his residential design projects. Even though he designed a multi-family houses, Wohlert's house design consists of mainly one-off large private houses located in a nice natural environment. In chapter 3, the general history of his house projects was studied. Among them, the first exhibition house for Forum was explained more deeply to show Wohlert's early house design philosophy. In chapter 4, three built house projects were analyzed in detail. Analytical diagrams were used to show the key elements in the residential space. They are program composition, circulation, spatialization elements, final construction. His buildings have been compared with Alvar Aalto, Frank Lloyd Wright, and other Scandinavian architects. But there are some major differences that make Wohlert's design unique. In chapter 5, the case analysis results were summarized together to highlight the specific design characteristics found in Wohlert's residential design process. The universal spatial quality found in his residential projects can be applied in contemporary spatial designs.

The objective of this study is to analyze the types and current status of development projects that underwent environment assessment in recent three years and provide basic data to encourage environment-friendly development projects in the future. This study was conducted by analyzing the pre-environment review reports and environment impact statements of development projects that took place in Gyeonggi province. Key findings are as follows. First, a total of 2,465 development projects spanning $173km^2$ were undertaken in Gyeonggi province in recent three years. This is equivalent to three times of the area of Anyang city. Second, types of development projects were in the order of factories and industrial parks, road construction, town (housing estates) development, sports facilities and waste treatment facilities. Public projects accounted for about 30%, while private investment projects represented 70%, indicating that private sector projects were as twice as high. The findings of this study show that the development density of Gyeonggi-do should be examined as a whole in order to develop a comprehensive, long-term plan and harmonize conservation and development systematically in Gyeonggi-do in a holistic perspective.

Function point model is the international standard method to measure the software size which is one of the most important factors to determine the software development cost. Function point model can successfully be applied only when the detailed specification of users' requirements is available. In the domestic public sector, however, the budgeting for software projects is carried out before the requirements of softwares ere specified in detail. Therefore, an efficient function point estimation method is required to apply function point model at the early stage of software development projects. The purpose of this paper is to compare various function point estimation methods and analyse their accuracies in domestic software projects. We consider four methods : NESMA model, ISBSG model, the simplified function point model and the backfiring method. The methods are applied to about one hundred of domestic projects, and their estimation errors are compared. The results can used as a criterion to select an adequate estimation model for function point counts.

It is an important issue in cost management to contract with the standard of cost estimate by the reasonable way in public construction projects. For the standard of cost estimate based on the Standard Estimating System, there is a difference of labor inputs between Standard Estimating System and actual quantities in construction projects. The duration of form work in multi-family housing depends on the manpower compared with other work, which is the critical path on the schedule management to be decided quality, and is the important to the cost management of construction projects. This study presented a simulation model of the productivity analysis for selecting the standard work type of form work in Multi-family housing construction projects.

This research aimed to propose an organizational system that implements a planning agreement in local small and medium sized city, Korea. To conduct this research, three successful cases were deduced using integration systems to investigate purpose and background of the planning agreement. Articles, reports, media, and participation in meetings and workshops related on this topic are used for collecting data and interview of regional activists and experts, and public officials were carried out. Among them, the case of Yeongju city that used the new integration system instead of pre-adminstration system was examined in detail. There are three local governments; Yeongwol-gun, Jeungpyeong-gun, and Yeongju city which have successfully fulfilled projects from various departments of central adminstration not projects of planning agreement. The similarity noticed between those three cases is to continue various projects from several departments of central adminstration for numerous years and contribute to regional revitalization. A successful factor was to establish organizational system and manage it for the integration plan and performance for appropriate regional and administrative characteristics. In particular, in the case of Yeongju city, organization for urban architectural management composed of civilian experts were formed, authorized status on administrative organization was established, and the function and role were identified. It is helpful to other local governments to carry out the projects of planning agreement as the case of Yeongju city is now a new method.
