Urban renewal projects, in the form of mega-projects, are being actively implemented both nationally and internationally to revitalize inactive cities. These programs, however, are difficult to manage efficiently due to their need for a large budget over a long period of time and due to conflicts with stockholders. Moreover, existing cost and duration management systems are structured with emphasis on the design and construction stage of unit projects, thus limiting their application to long-term mega-projects that are integrated with various facilities. To solve these problems, this study developed a web-based system that can collectively manage the cost and duration of mega-projects at a program level. The unit modules included in the system--CBS organization, construction cost and duration prediction, and total cost and duration prediction--can support decision-making at the early stage of the program. Furthermore, the modules, which include contract management, execution management, change management, and program progress management, support the program operations for its successful accomplishment. The web-based cost and duration management system developed in this study is expected to be used as a valuable tool that supports the successful accomplishment of mega-projects through their efficient management throughout their life cycle.

In general, the early stage of urban renewal such as preparing a master plan and processing administrative works including planning permission are conducted by local governments in Korea. The local governments need to review the status of projects that are undergone in other local governments' territories. However, no integrated information system to manage information to this end at the level of nation exists in Korea. If the system would be developed, it may support central government to obtain information on required resources at the national level. In addition, local governments can gain guidance on the process and recognize potential problematic situations from others experience. The system should include functions to collect data on project summary, cost and schedule of projects according to local governments. The expected effects from using the information system are as following. First, information generated from project practice become more credible on account of management at the national level. Because the authorized party such as system administrative agents of governments are responsible for collecting and managing data. Second, the unified information system with no regard to the place where projects progresses reduces the efforts for accumulating reference data for aiding local governments decision making by providing appropriate information timely. Also, enhanced information accessibility for stakeholders make the project process clear. Finally, oversight management is enforced with visualization technology adopted in the system, presenting master plan and mass model including information on usage by floors and progressing information graphically. Ultimately, potential challenges can be anticipated by considering records accumulated from other local governments' projects. This paper presents concept, functionalities, and architecture of information system enabling to manage data from individual projects and aggregate those for oversight management for local and central governments. As a part of systems analysis, general requirements of briefing system for governments and necessary data fields to this end are identified.

호주 멜버른지역에 소재한 맬버농은 작은 시급정부로, 시 정부 주도로 과거 군수산업용지를 정화하여 주택지구로 재개발하였고, 도시기반시설을 정비하여 경관을 개선하는 한편, 도심을 활성화하고 있다. 도심의 빈 점포를 임대하여 대학 캠퍼스를 조성하고, 도심에 Little Saigon이란 베트남 촌을 조성하는가 하면, 빅토리아 대학과 연계해서 창조산업 관련 창업보육사업을 통해 기업유치 및 기업육성을 위해 노력하고 있다. 이 사례에 기초해서 볼 때, 호주는 창조도시사업을 통해 사회 경제적, 도시경관적 여건을 개선하는데 성공하고 있으며, 그러한 과정에서 대학과 각급 정부, 그리고 시민단체의 역할이 큰 것으로 파악된다.

정비사업에 있어 공공의 역할이 강조되고 있는 상황에서 객관적으로 정비사업이 필요한 지역을 선제적으로 살펴보는 것은 매우 중요하다. 이 연구의 목적은 공간데이터를 활용하여 재정비가 필요한 지역을 탐색하고, 재정비 대상지 유형화 및 특성을 분석하는 것이다. 이를 달성하기 위해 공간데이터를 사용하여 커널밀도함수와 K-means 군집분석을 수행하였고, 재정비 대상지역 발굴 방법을 모색하였다. 주요연구결과 및 시사점을 요약하면 다음과 같다. 첫째, 개발 용적비와 노후도 지표를 기준으로 서울시 전역에 걸쳐 587개 재정비 대상지를 구획하였으며, 선도사업·신속통합기획 후보지 비교결과 절반 정도 일치성을 확인하였다. 둘째, 재정비 대상지는 공공에서 지정한 선도사업 후보지에 비하여 상대적으로 주거환경이 열악하였다. 셋째, 재정비 대상지는 통계적으로 뚜렷하게 유형화되지 않았으며, 사업요건별 유형화의 타당성을 확인하였다.

This study focused on the fact that there are a lot of alleys in some areas of the Urban Renewal New Deal project. In this study, we proposed a method to construct a spatial module by combining small modules. It is expected that the combination of small modules developed in this way will help revitalize the New Deal of Urban Regeneration. In the future, additional joint details will be developed, structure review will be conducted.

Underground infrastructure systems provide essential public services and goods through buried structures including water and sewer, gas and petroleum, power and communication pipelines. The majority of existing underground infrastructure systems was installed in green field areas prior to development of complex urban built environments. Currently, there is a global trend to escalate major demand for underground infrastructure system renewal and new installation while minimizing disruption and maintaining functions of existing superstructures. Therefore, Engineers and utility owners are rigorously seeking technologies that minimize environmental, social, and economic impact during the renewal and installation process. Trenchless technologies have proven to be socially less disruptive, more environmentally friendly, energy conservative and economically viable alternative methods. All of those benefits are adequate to enhance overall sustainability. This paper describes effective sustainable solutions using trenchless technologies. Sustainability is assessed by a comparison between conventional open cut and trenchless technology methods. Sustainability analysis is based on a broad perspective combining the three main aspects of sustainability: economic; environmental; and social. Economic includes construction cost, benefit, and social cost analysis. Environmental includes emission estimation and environmental quality impact study. Social includes various social impacts on an urban area. This paper summarizes sustainable trenchless technology solutions and presents a sustainable construction method selection process in a proposed framework to be used in urban underground infrastructure capital improvement projects.

As impervious area increases due to urbanization, rainfall on the impervious area does not infiltrate into the ground, and stormwater drains quickly. Low impact development (LID) practices have been suggested as alternatives to infiltrate and store water in soil layers. The practices in South Korea is applied to urban development projects, urban renewal projects, urban regeneration projects, etc., it is required to perform literature research, watershed survey, soil quality, etc. for the LID practices implementation. Prior to the LID implementation at fields, there is a need to simulate its' effect on watershed hydrology, and Storm Water Management Model (SWMM) provides an opportunity to simulate LID practices. The LIDs applied in South Korea are infiltration-based practices, vegetation-based practices, rainwater-harvesting practices, etc. Vegetation-based practices includes bio-retention cell and rain garden, bio-retention cells are mostly employed in the model, adjusting the model parameters to simulate various practices. The bio-retention cell requires inputs regarding surface layer, soil layer, and drain layer, but the inputs for the drain layer are applied without sufficient examination, while the model parameters or inputs are somewhat influential to the practice effects. Thus, the approach to simulate vegetation-based LID practices in SWMM uses was explored and suggested for better LID simulation in South Korea.

공공적 주체로 대표되는 한국자산관리공사가 시행하였던 국유지 위탁 시범개발사업의 특성분석을 통하여 공공성의 확보를 위한 유휴공간의 공간재생 시 고려되어야 할 내용을 공간, 용도, 과정의 측면에서 분석한다. 여기에서 각각 다음의 한계를 나타내는데 비연속적 공공공간은 공공주체가 민간주체의 개발이익 사업과 다름이 없음을 보여주며, 비 공공적 용도의 배치는 공공성과 이익성의 균형을 맞추기에 원천적인 한계를 나타낸다. 또 폐쇄적인 과정에서는 공개성이라는 공공성의 원칙을 지키기 힘들며 공공의 참여와 관심을 유도하는 공공적 재생의 실현에 한계를 보일 수밖에 없다. 이상과 같이 공간, 용도, 과정의 측면에서 살펴본 바 다음과 같은 결론을 도출하였다. 1. KAMCO가 시행하는 프로젝트는 공공기관이나 공공성을 적정한 수준에서 담보하는 절차가 반드시 필요하다. 2. 수탁기관이 청구하는 위탁수수료의 적정한 보장과 이익의 한계선을 공공주체는 프로젝트 기획 시 명확히 하여 일정부분이 공공성을 향상시키는데 쓰여야 한다. 3. KAMCO의 다양화된 공개방식의 개발과 건축계획이 필요하다. 그리고 KAMCO 개발의 건축적 공간계획에서 공공성을 담보할 수 있는 자율성과 심의 할 수 있는 전문기구와 예산이 요구된다.

정비사업은 노후한 주택 단지를 철거하고 그 대지위에 새로운 주택을 건설하는 사업으로 대도시의 신규주택을 공급하는 주요 역할을 수행하여 왔으며 도시의 효율적인 재 창조의 필요성이 대두되면서 정비사업에 있어 새로운 패러다임이 요구되고 있다. 정비사업은 각 단계별로 전문지식을 요하는 절차로 이루어져 있으나 조합의 전문성 부족 및 주체간의 의견 대립으로 사업추진과정에서 많은 어려움을 직면하고 있다. 특히 부도덕한 조합의 각종 비리와 연관된 사고 및 시공사 위주의 사업진행으로 정비사업을 바라보는 외부의 시각은 매우 부정적인 것이 현실이다. 이에 도정법의 개념 및 정비사업의 현황을 살펴보고 건설사업관리를 적용하는 방안을 모색하여 본다. 본 연구를 통해 건설사업관리가 정비사업의 효율성을 제고하는데 일조하기를 기대한다.
