Previous studies reveal the need for a tool to cost estimation of building design in early design stages. This paper proposes an internal finishes cost model tool to address this need. The tool allows users to evaluate the functionality, economics and quality of finishes concurrently with high-rise building design. Lack of information in the early stages of the project enables a relatively accurate estimates of work to raise up. Measurements are automatically extracted from simple design information and profile driven estimates are revised in real-time. The data model uses a flexible unit rate system that can easily be extended to other estimate dimensions such as mix-use building surcharge rate estimation. The approach illustrated in this paper is applicable to BIM tool conceptual estimation that support for massing purposes other than the one chosen for this study.

Various mixed-use buildings have been developed in the process of resolving the issue of 'urban regeneration' in the modern city. In this urban regeneration process, the size of the mixed-use buildings and the level of their functional complexity have been increased. It requires a quantitative and systematic approach in order to analyze the internal circulation flow within the large-scale commercial mixed-use buildings. Circulation system and environmental factors, respectively, have been vital criteria for the effectiveness of a Wayfinding design within the mixed-use buildings. The circulation system in this paper consists of 1) the number of the incoming paths at each node, and 2) the angle of directional transition from the incoming paths at the node. The environmental factors include 1) color tone, 2) materials, 3) lighting, and 4) pattern of the interior design of the mixed-use buildings. In this paper, the author develops a method of investigating the influence of the correlation between the circulation system and the environmental factors on the design of Wayfinding on the view of the remodeled COEX MALL interior design.

As public space such as plaza and square in the compact city type multi-use complex is a social public space that various communication and cultural exchange take places in city environment. The purpose of this study is to analyse and categorize the design elements as a valuation basis for the public space in the compact city type multi-use complex. The scope of contents of this study is focused on the Central City, COEX and Western Dome facilities in Korea. This study review based on the previous studies and statistical analysis about questionnaires obtained from 131 users of three facilities were conducted for this study. The results of the survey as follows accessibility, comfort, exchange were extracted as the aspects for evaluation for functional activity and connection, openness, hierarchy were extracted as the aspects for evaluation for space formation. The K facility's priority aspect is the accessibility and the S and the W facilities' are the openness.

The purpose of this study is analysing the characteristics of interior space aiming for the exterior space in mixed-used development. The range of this study is limited as passage, department store, shoppingmall and Mixed Use Development. The method of this study is as follows. First, analysing the 7 samples of the interior space aiming for the exterior space in MXD through the framework of public character categorized as 5 factors, accessibility, openness, comfort properties, connectivity, convenience in use. Second, drawing a conclusion from the precedent step. The result of this study is as follows. First, the interior space has become bigger with time. And the public character is expanded with having the same structure of the city space. Second, the interior space solves the problem of the exterior space of city but prefers the same factors with the exterior space. Third, the street in the interior space has the characteristics of openness and comfort properties through diversification. And the open space is planned in various parts of the MXD and has the character of accessibility and connectivity.

This study has been given careful consideration to an induction of the mixed-use districts for the efficiency of Land Use, the rational plot planning and the mixture/complex among the functions in order to complement the zoning plan with the primary purpose to purify the usage of landscape. Furthermore, it is aimed to indicate the implementations through the medium of the in-depth analysis about the cardinal factors such as the standards on the regional location, building size and building uses in the case of designating the Mixed-use districts.Abstract This study has been examined by the aspect of scope for securing the adequacy of Site Division Restriction, Floor Area Ratio, Building Coverage Ratio and Outdoor Area Ratio in the "Mixed-Use Districts" and especially, by the medium of the in-depth analysis about the actual condition of building and outdoor space scales. It has been deduced the scale standards by using the simulation and correlation analysis among the factors of those buildings and outdoor spaces. Moreover, it has been applied the analysis method of using the building scale, especially, the latter has analyzed the total 1,656 different types classified by 3 patterns of Plottage and Building Coverage Ratio, 9 patterns of the factor change on Outdoor Area Ratio and 8 different patterns of road width.

Multi-use housing and commercial buildings have been emerged according to social and economic changes of CBD in Seoul Metropolitan Areas. The purpose of this study is to clarify the characteristics of the multi-use building, to analyze the problems on the base of survey and to suggest the solutions for architectural planning, focusing on eco-friendly dwelling environment. A field survey with 46 subjects has been carried out with structured questionnaire. Some problems in planning of the complex building have been discussed in terms of environmental issues and design criteria. In conclusion, basic planning directions for improving the building environmental quality have been suggested.

It is needed to regenerate declined industrial districts in downtown area through to invite new industry and to improve urban environment. The purpose of this paper was to make suggestions on the urban regeneration for the districts. I have taken a literature research and a site analysis with cases of 'the South Lake Union' in Seattle and 'Pearl District' in Portland, USA. The result of the analysis was as follows: (1) The land use was changed to mixed use of business-commerce-recreation. The building use was changed to facilities for work, play and live. (2) Infrastructures were improved for user oriented facilities such as pedestrian friendly street, public parks & open spaces, public transportation system, and life supporting facilities. (3) The place identity was enhanced through the preservation of urban structure-tissues, renovation of existing buildings, and preservation of historical heritages.

The purpose of this study is to evaluate the urban land used by the Urban Land Use Information System (ULIS) which can supply the micro-level land usc information for the understanding of micro-level urban spatial structure and district-level planning and managements(such as urban design, redevelopment planning and district-level transportation planning, etc.). The study evaluates the current situation of urban land use database and suggests the prototype of urban land use database using GIS. The planning and management of post-modern city which has characterized by diversity and the mixture of land use, need more detail and quantitative information about land use. Recent redevelopment and reconstruction of existing physical condition are increasing the density of activity. It raises urban problems such as the shortage of infrastructure and traffic congestion, etc. In this process we need to construct information system which monitors current land use situation.

A clad material is a different type of the typical composites which are composed of two or more matericals joined at their interface surface. The advantge of cald material is that the combination of different materials can satisfy both the need of good mechanical properties and the other demand of user such as electrical properties instantaneously. This paper is concerned with the direct and indirect extrusion processes of copper-clad aluminum rod. Extrusion of copper-clad aluminum rod was simulated using a commercially available finite element package of DEFORM. The simulations were performed for copperclad aluminum rod to predict the distributions of temperature, effective stress, effective strain rate and mean stress for sheath thicknesses, die exit diameters and die temperatures.
