This paper aims to suggest a validity analysis model that would be helpful for local governments considering u-City construction projects and a methodology for them to promote build-transfer-lease (BTL) u-City projects. This methodology mainly uses quantitative and qualitative analysis based on the Value For Money (VFM) designed by the Public and Private Infrastructure Investment Management Center (PIMAC) under the Korea Development Institute (KDI). BTL projects requires a large amount of capital and involves long-term investments. Therefore, multi-faceted validity analysis is required for the success of a project. This study will enumerate various factors to be considered in the pre-analysis of validity of BTL projects and suggest a methodology to verify them. A case study of a BTL project promoted by Ansan City assisted in designing this study in detail.

Ubiquitous City (u-City) and Intelligent Transport System (ITS) provide services, which are different from each other yet have close relation to each other partially. Thus, since a redundancy issue occurs or it is difficult to efficiently provide services depending on the relation degree, it is required to analyze the relation of services between the two systems and to elicit a priority. A table of relation among the services was created and the relation degree was analyzed by performing a survey for experts. As a result of calculating the total marks by accumulating and summing up the survey results, the incident management service and u-accident/calamity and disaster service of the ITS had the lowest value. The project priority was as follows: The basic principle of the project was that services with high relation degrees shall be worked on first. The services were categorized in each step and packaging the services could result in the synergy effect. This study is significant since it analyzed the relation degree between u-City and ITS and proposed schemes for efficiently working on the project by eliciting the priority of the services based on the analysis results.

In this paper, we propose a master planning framework for the development of u-City export model. The framework consists of a general plan, a construction plan, an operation plan and an evaluation plan for the successful penetration of u-City overseas market, respectively. In order to derive those planning elements, governmental policies and related literature for u-City export is thoroughly reviewed. The framework is applied to a project which develops an u-City export model. This study will contribute to the realization of such governmental policies for the revitalization of u-City export as well as the activation of u-City export by the private sector.

A city development has been focused on solving a housing shortage of city resulted from rapid industrialization and population increase in city. However, such a development has caused many problems in environment, economy, safety, and so on. In recent, therefore, a new paradigm of a city development is required, and thus ubiquitous city (U-City) concept appears. U-City development, which combines construction method and IT technique, creates a new composite space, and help people improve quality of life in terms of solving many problems caused by existing method of a city development. However, there is no guide to build U-City up to date, and most present U-City projects have processed following past method of city development. Therefore, an objective of this paper is to suggest an explicit procedure of enforcement design in U-City system.

The u-City construction project has become a hot topic In the construction market because it seems economic value-added field for construction firms. However, construction firms don't willingly participate in the u-City construction market because the future business environments for the u-City are very uncertain. Scenario planning is a very powerful method in managing this complex planning situation and is based on scenarios that help each enterprise appropriately adapt itself to its own business environments. Therefore it Is based on the main principles of systems thinking and multiple futures. For the purpose of dealing with such uncertainties, this paper attempts to develop the possible market scenarios of the u-City construction market through a scenario planning approach. From this perspective, we considered various aspects of the u-City construction such as market demands, technology development, policy level and management environment. After considering the relevant issues, we identified the main trends and key uncertainties. Then, we developed three coherent u-City construction market scenarios. On the basis of the proposed scenarios, the business strategies of potential construction firms in the u-City construction market has been formulated. Therefore, construction firms can use these scenarios as a basic data for market analysis and business strategy. Therefore, this paper is able to enhance the participation of construction firms in the u-City construction market.

Recently, the concern of ubiquitous City(u-City) in each level of governments is on the increase, and they are professing themselves to follow the u-city concept on constructing new urban development or urban renewal project. But the u-city plan and construction proceed as the simple sets of advanced technology without fundamental space concept or space plan of the u-city. Therefore, the u-city as a citizen's living space and a basic urban environment is defined in this article, the viewpoint of the space plan and the recent trends of u-city in korea are reviewed. On the basis of this review, this article proposed an approach of the spatial plan for a u-city construction, here the approach consisted of the 3 stages of planning, constructing, and maintaining of the u-city, and finally the role of the participant in the each stage and spatial hierarchy was proposed.
