This study suggested a new model in consideration of long life and constructability of apartment house suggested in the former part. New model suggested the possibility of cost saving based on the idea that people trend to reject because of the recognition that the new model would cost a lot of expense which work as the barrier for the expansion and distribution at the local market so as to prepare the ground for its activation. The Study was aimed at verifying the possibility of cost saving through comparing it with the existing standard apartment house system centered on the skeleton and cladding system among the new structural design models suggested in the former part. Assuming that these existing standard both models should be changed structural design into new model system, the quantity volume, cost and construction period along with the alteration of finished materials between two models were compared altogether. Simultaneously BIM library was built for easy taking-off bill of quantity and consideration of working methodology for construction working cycle, which was translated into construction cost so as to derive the cost of the two subject systems to be counted. Through the analysis, it was concluded that new model would secure variability in the future and constructability along with shortening the construction period (29%) and achieve cost saving (13%) of construction against the those of existing model.

The purpose of this study is to examine the residents' preference to community facilities in national rental apartment complexes. Twelve housing complexes were sampled and researched with questionnaire and field-surrey methods. The data from the questionnaire survey were processed with SPSS 14 and analyzed by regional group, size of complex, and arrangement plan of facilities. The complexes are located in two legions, Seoul and Gyounggi province. They were also sorted into three groups by size: less than 500 households, 500 to 1,000, and more than 1,000. Lastly, the complexes were categorized into three types: those where facilities are concentrated in or around a single building, dispersed into several places, and located in residential buildings. The results are as follows: Majority of the community facilities are established outdoor and, therefore, the indoor facilities are relatively more insufficient. Especially, there is a shortage of indoor gymnasium while the demand is increasing. It is partly because there is no regulatory guideline on indoor gym requirements in housing complexes. The resident satisfaction measurement shows significant comparison according to region and complex size. The level of satisfaction with garden/kitchen-garden, pond/fountain/streamlet is higher at the complexes in Gyunggi. The residents of larger complexes give positive feedback about spells facilities while those of smaller complexes are more satisfied with education-related facilities such as library and study. The measurement of resident needs shows significant comparison according to complex size and facility arrangement plan. The residents of smaller complexes are more in need of community facilities. In both regulatory standards and actual condition, community facilities are more insufficient at small complexes with less than 500 households.

Insulation and condensation performance evaluation (I&CPE) is an important energy analysis. While considerable amount of data are already represented in a Building Information Model (BIM), the lack of interoperability between BIM modeling and I&CPE programs prevents the simulation process from being efficient and accurate. This study proposes a prototype of a BIM-based I&CPE simulation program, in order to enhance the interoperability between BIM modeling and I&CPE programs. This study discusses the information flow process, defines the required information and its level of detail, develops standardized libraries, and finally proposes a prototype that consists of a data extraction module, conversion module, and performance module. The assurance of interoperability between systems might greatly benefit architects and energy professionals.

The purpose of this study is to find out how to effectively utilize the public facilities site that is being used in the new town for the expansion of newly required public facilities, because it is difficult to carry out redevelopment projects in apartment complexes of 1st generation new town due to the rigidity of land use and macroeconomic conditions. This study examined the following three ways to effectively utilize existing public facilities sites for Pyeongchon new town. First, it suggested how to secure the parking lot by deciding multi-dimensional urban planning facility of public facilities such as parks and schools in superblock that lacks parking space of apartment complex. Second, it suggested a plan to accommodate the demands of public facilities required by increasing the building density of existing public buildings in commercial district as an example of the Anyang Tax Office. Lastly, it suggested a way to install additional functions required by users through the reorganization of the existing public facilities and some extensions by examining the Pyeongchon library.

Korea's construction industry experienced no difficulty managing the costs of finishing work items in the apartment housing field thanks to the uniform specification and the standardized costs of finishing work items. Finishing work items have continuously become more high class and differentiated, which has caused the costs of finishing work items to rise. This study identified problems with the cost management when planning finishing work items and choosing their alternatives based on the current process applied to the planning stage of finishing work items. It also found problems with the information management of finishing work items including design, cost, and work information that took place in bulk. Based on the identified problems, the design, cost and work information of finishing work items was integrated so that they could management the costs and information when planning finishing work items and selecting their alternatives. Then a cost-based information management process was suggested for finishing work items by improving each of the project cost management elements. Finally, an information model for finishing work items was built by studying the ways to integrate the information hierarchy and library of finishing work items.

The Biotope Area Ratio (BAR) is a quantitative pre-planning index for sustainable development and an integrated indicator for the balanced development of buildings and outdoor spaces. However, it has been pointed out that there are problems in operations management: errors in area calculation, insufficiency in the underground soil condition and depth, reduction in biotope area after construction, and functional failure as a pre-planning index. To address these problems, this study proposes implementing LIM. Since the weights of the BAR are mainly decided by the underground soil condition and depth with land cover types, the study focused on the terrain and pavements. The model should conform to BIM guidelines and standards provided by government agencies and professional organizations. Thus, the scope and Level Of Detail (LOD) of the model were defined, and the method to build a model with BIM software was developed. An apartment complex on sloping ground was selected as a case study, a 3D terrain modeled, paving libraries created with property information on the BAR, and a LIM model completed for the site. Then the BAR was calculated and construction documents were created with the BAR table and pavement details. As results of the study, it was found that the application of the criteria on the BAR and calculation became accurate, and the efficiency of design tasks was improved by LIM. It also enabled the performance of evidence-based design on the terrain and underground structures. To adopt LIM, it is necessary to create and distribute LIM library manuals or templates, and build library content that comply with KBIMS standards. The government policy must also have practitioners submit BIM models in the certification system. Since it is expected that the criteria on planting types in the BAR will be expanded, further research is needed to build and utilize the information model for planting materials.

While the government policy to fully adopt BIM in the construction sector is being implemented, the construction and utilization of landscape BIM models are facing challenges due to problems such as limitations in BIM authoring tools, difficulties in modeling natural materials, and a shortage in BIM content including libraries. In particular, plants, fundamental design elements in the field of landscape architecture, must be included in BIM models, yet they are often omitted during the modeling process, or necessary information is not included, which further compromises the quality of the BIM data. This study aimed to contribute to the construction and utilization of landscape BIM models by developing a plant library that complies with BIM standards and is applicable to the landscape industry. The plant library of trees and shrubs was developed in Revit by modeling 3D shapes and collecting attribute items. The geometric information is simplified to express the unique characteristics of each plant species at LOD200, LOD300, and LOD350 levels. The attribute information includes properties on plant species identification, such as species name, specifications, and quantity estimation, as well as ecological attributes and environmental performance information, totaling 24 items. The names of the files were given so that the hierarchy of an object in the landscape field could be revealed and the object name could classify the plant itself. Its usability was examined by building a landscape BIM model of an apartment complex. The result showed that the plant library facilitated the construction process of the landscape BIM model. It was also confirmed that the library was properly operated in the basic utilization of the BIM model, such as 2D documentation, quantity takeoff, and design review. However, the library lacked ground cover, and had limitations in those variables such as the environmental performance of plants because various databases for some materials have not yet been established. Further efforts are needed to develop BIM modeling tools, techniques, and various databases for natural materials. Moreover, entities and systems responsible for creating, managing, distributing, and disseminating BIM libraries must be established.

A model for radiological dose assessment in an urban environment, METRO-K has been developed. Characteristics of the model are as follows ; 1) mathematical structures are simple (i.e. simplified input parameters) and easy to understand due to get the results by analytical methods using experimental and empirical data, 2) complex urban environment can easily be made up using only 5 types of basic surfaces, 3) various remediation measures can be applied to different surfaces by evaluating the exposure doses contributing from each contamination surface. Exposure doses contributing from each contamination surface at a particular location of a receptor were evaluated using the data library of kerma values as a function of gamma energy and contamination surface. A kerma data library was prepared fur 7 representative types of Korean urban buildings by extending those data given for 4 representative types of European urban buildings. Initial input data are daily radionuclide concentration in air and precipitation, and fraction of chemical type. Final outputs are absorbed dose rate in air contributing from the basic surfaces as a function of time following a radionuclide deposition, and exposure dose rate contributing from various surfaces constituting the urban environment at a particular location of a receptor. As the result of a contaminative scenario for an apartment built-up area, exposure dose rates show a distinct difference for surrounding environment as well as locations of a receptor.
