The Purpose of this study is to improve construction quality with area calculation methods from BIM design technology. BIM has been supporting public-private-organizations and academic circles as a solution technology to manage and produce informations effectively from construction field including facility manage one. BIM standards are necessary but not sufficient for achieving perfect practical application in South Korea. In particular, development of architectural rule based area calculation methods is very urgent and important to improve construction quality. To solve those problems, methods and standards on area calculation are developed and its effectiveness of the proposed BIM-based methods is defined through the analysis between the existed area calculation method and process which are 2D based. This study will not only improve economic efficiency and accuracy of the construction quality but also settle the BIM environment in the domestic architecture.

Recently, as the era of economic cooperation on the Korean Peninsula approaches, the role of the building sector, such as humanitarian reorganization of North Korean housing, is increasing. The purpose of this study is to find out the current location of North Korean housing standards through the North Korean Housing Survey. For the survey, a survey was conducted through 79 North Korean defectors. The main construction methods of North Korean housing are reinforced concrete, steel framed, wooden framed, masonry, and reinforced concrete walled and prefabricated. The residential environment satisfaction items consist of durability, waterproof, heating, ventilation, heat insulation, air tightness, mining, soundproofing, disaster safety, fire safety, and crime prevention. The result is as follows. The housing construction method in North Korea, which lived at that time, consisted of 21 people (30.88%) of reinforced concrete frames, 18 people (26.47%) of wooden frames, 17 people (25%) of masonry walls, 5 people of prefabricated structures (7.35%), and reinforced concrete. Two people (2.94%) were walled. Among these, the wooden frame type had the lowest satisfaction level for each item, and the reinforced concrete had a high level of dissatisfaction in the items of heating, confidentiality, and disaster safety, and the other item had a high level of satisfaction. The masonry wall type has a relatively high satisfaction level in terms of insulation, confidentiality, mining, and disaster safety.

This study aims to understand differences in what specialists groups think important to establish district units plans. The result of the study is as follows. There were differences in thinking by specialists on standards and procedure of establishment, characteristics of the plans. For the standards of establishment, there was a remarkable difference in thinking on the importance. In the search for the importance on the establishment procedure, the groups of architects, construction firms, researchers and professors & instructors thought listening to opinions of residents important and public officials considered review by the City Planning Council important. In the survey on characteristics of district units plans, the most respondents answered 'plans leaded by private sectors focusing on residents' and 'plans to practice for actualization of urban plans'. Public officials and researchers answered that district units plans should be practical plans for actualization of urban plans with strong characteristics of work. The groups of architects, construction firms and professors/instructors mostly thought that private sector leaded plans focusing on residents as characteristics of district units plans. It was understood that construction firms think that the parts related to conditions for construction across overall standards of establishment, procedure of establishment are important. The specialists who think that the plans should be private sector leaded plans focusing on residents on which the residents' opinions are reflected were the groups of architects and professors/instructors.

The modular apartment has been completed for the first time in Korea through the national research and development (R&D) project in December 2017, and 30 households moved in. Although conditions such as technicality and constructability have to be satisfied to adopt and spread the modular apartments in the future, economic feasibility is the most important factor among the conditions. The economic feasibility of modular apartments can be compared with that of existing reinforced concrete (RC) structure apartments. It is highly important to reduce the construction cost through standardization above all. The standardization refers to establishment of national design standards and principles, and it is important for manufacturers and building companies to comply with those standards and principles. The modular construction (MC) skill in Korea is at an early adoption stage and the MC market is not widely expanded yet. Thus, the application of the MC design, which is the basis of the standardization, has not been widely accepted. However, related R&D projects are now performing mainly by the Ministry of Land, Infrastructure, and Transport to promote modular apartments in recent years and the design standardization standard (draft) is now prepared to be notified as a result of the steady research. Furthermore, pilot complexes for demonstration purpose are under construction, starting from public rental apartments. Thus, MC method-applied public rental houses will be spread in near future. This study aims to investigate the current design status in the Ga-Yang Housing as a pilot modular complex to produce and supply more economical and efficient modular houses, and analyze the problems by comparing the design standardization standards with pre-notified design standardization standards and summarize the modifications between them thereby presenting foundational data for establishment of the design standardization in the modular business industry.

In many parts of the world, low cost housing used to be built and maintained by the governments, based on designs and detail specifications prepared by the public sector with construction carried out by contractors. Results vary due to differences in design standards, workmanship and property management, depending also on the neighbourhood's care of the estates and their pattern of usage. In the UK, where Private Finance Initiative (PFI) has been used for infrastructure projects, there have been successful cases of city estate being transformed by PFI. These PFI housing schemes involve new-build, refurbishment as well as facility management. Unlike traditional construction, which is based on prescriptive specifications, PFI housing is based on output specifications. A study has been undertaken to compare the two specification approaches as they are applied to housing estate. Results are enlightening and serve as good reference to cities such as Hong Kong SAR and Singapore, where public housing provisions have been a major concern of their citizens as the building stock gets older.

Since 1990s, we have achieved a certain level of success in standardization of design, construction, and material on housing and public buildings with the national-level promotion. A practical connecting device that can synthesize all the serial processes is required to maximize the effect of construction material standardization. However, desired outcome of the standardization is not achieved yet because these serial standards and notification practices are decided by each part of the process and some are congested. In this study, we aim to improve a general organizational system of Korean Industrial Standard (KS) which is the most fundamental tool for the standardization of construction materials moving from a conventional idea that the standard is only for the material and components producers to a concept that can also be shared by the designers and construction workers. To achieve this, we propose an improvement plan for the Korean Industrial Standard in the perspective of three-tier classification system.

Research on the "Modernized Korean traditional housing" (Hanok) has been actively studied in succeeding to Korean traditional housing and providing the public with housing that required for modernized life style. The purpose of this study is to classify work sections for Hanok specifications. This paper analyzed the concepts and characteristics of existing specifications. It was found that the absence of standard classifications is one of the causes of missing work items and mixed scopes. Also, the contents of carpentry works have low level of details. Therefore, Hanok specifications, in this study, are required to have upper level standards and to encompass traditional and new construction methods. Further research will develop standard classifications, standard codes, and automated systems of Hanok specifications for improving quality and effectiveness.
