Recently, the issue of construction safety is growing. In the construction industry, accidents have continued to increase since 2000. In particular, the number of accident deaths at small and medium-sized construction sites accounts for 72.11% of the total number of accident deaths in the construction industry. For construction safety, prior safety evaluation systems such as Design for safety and safety management plan preparation are in place. However, at construction sites, these systems are recognized as formal legal documents, and their effectiveness is greatly reduced. Therefore, in this study, a linkage model that links design safety review information and safety management plan information was presented so that the safety management plan can be efficiently established. In addition, the effectiveness of the proposed process was verified as an example of actual work. The linkage model will contribute to improving the safety management environment at the site by increasing the productivity of safety management work by enabling easy sharing of risk factor information in the construction stage safety management work. The results of this study will be used as basic information for the development of the integrated safety management system.

[Purpose] Recently, skyscrapers have sharply increased throughout the world, including South Korea. Although a skyscraper has its own merit such as the landmark of a city, it also has various problems like massive energy consumption. This study is aimed to establish the concept of environment-friendly skyscraper and propose a plan to realize skyscraper after analyzing the architectural, facility and environmental friendly elements of skyscrapers. [Method] This study lists up skyscrapers over 40 floors and 200 meters high. Upon 10 constructed buildings, it analyzes their basic plans and the green building technologies applied to them and suggests effective and environment-friendly architectural plan. [Result] This study examined the distinctions of the layout, shape, facade, and floor plan plane of 10 skyscrapers and found out specific techniques to be used for the use plan of natural energy, plan for saving resources and reducing wastes and a plan for environmental architecture and system.

Quite a few of persons often fall into an error that ISO has happened an additional work at construction sites. Supervision works, however, are carried out in compliance with 'Guidelines for the Supervision Works' which is including most ISO Requirements. Additional requirements needed for the supervision works are not many. This study has studied on the ISO application of supervision works in relation to, 1) ISO 9001 & KS A 9001 Quality Management System Basic Model, 2) The Process of Railway Construction Work Supervision Quality Management Plan, 3) Supervision Work Performance Guide Book(2005) & KS A 9001(2001) Standard, at the railway construction sites.

As the recent economic downturn continues to undermine the profits of construction industry in Korea, it has become ever more pressing to improve productivity of the industry. Since construction site management manpower staffing plan has close bearing on the productivity of construction projects, it is essential to estimate and mobilize adequate number of resources as per conditions and characteristics of each construction site. However, there are no reference approaches in practice to provide baseline for site management manpower staffing plan or estimation of manpower requirement. Therefore, this study aims to examine factors affecting productivity that warrants first and foremost consideration in development of site management manpower staffing plan during the initial phase of building construction project by conducting survey on industry stakehoders with hands-on responsibilities in construction sites and analyzing their responses. Conclusions herein will provide basic inputs for subsequent studies on development of site management manpower staffing plan as per project characteristics.

Energy consumption of building is given a sizable portion in total national energy conservation and if current trends continues, energy conservation level will rise as level of developed country. For this reason, a basic plan is proposed for integrated management system to manage energy conservation of buildings using a link with energy information and building information. Specifically, the questionnaire investigation conducted by building energy expert is performed to determine the projects along with time schedule and demands level of management system. In addition, to investigate study on energy usage information and management situation the management architecture of energy supplier is also studied.

This study has its purpose on analyzing the problems of data connection between general management institution and itemized management institution shown through the college information disclosure project and presenting the plan to substantialize data connection between general management institution and itemized management institution. To make close inquiry into the related problem and induce plans for substantialization, this study analyzed the previous related research data as well as the connection status of information disclosure item of Korea Foundation for the Promotion of Private School, the itemized management institution, to induce problems; induced substantialization plan for data connection of itemized connection institution. As for the substantialization plan based on such, plan to integrate schools and department codes, plan to automatize data connection and plan to secure reliability of information were established. It is anticipated that the plan to substantialize data connection between management institutions reckoned through the result of this study would be used as the basic data for information disclosure project providing various reliable information from Ministry of Education, Science and Technology, General management institution, itemized management institution and college.

Recently, intensive urban redevelopment concentrated on new towns has reduced the number of settled population, and weakened various functions such as commercial, culture, education and welfare in old towns, and made the stagnation and declination of the entire or some parts of old towns. Urban regeneration project means renewing cities' functions in terms of physical, environmental, social, cultural, industrial and economic aspects or revitalizing the existing functions through improvement project in the entire or part of a city, which is now drawing keen attention from the public. However, urban regeneration project is huge in scale, needs long construction period and various complex facilities, and also characterized by complicated relations with many stakeholders. Due to such characteristics, there are many risks in the project. Therefore, systematic risk management is absolutely necessary to efficiently manage various risk factors inherent in urban regeneration project. The purpose of this research proposes a basic model to establish risk management plan and work process in order to help project participants to perform risk management more systematically and rationally in the development phase of urban regeneration project.

Recent economic slump has highlighted the needs for the construction industry to develop strategies to improve productivity and overhaul organization structure. Notably, it is urgent to improve productivity of apartment building construction projects that account for about half of the aggregate revenue of building construction projects in Korea. As construction site management manpower staffing plan has close relation with the productivity of building construction, it is essential to staff construction sites adequately in consideration of site conditions and characteristics. However, construction companies of Korea are still far from developing site management manpower staffing plan in reference to quantitative standards. Therefore, this research aims to analyze site management manpower staffing plan of apartment building construction project by means of density analysis. To be more specific, site organization charts and staffing plans of apartment building construction projects put together by large construction companies in Korea are studied and essential resources and their mobilization time of apartment building construction projects are examined. Conclusions herein will provide basic inputs to subsequent studies of apartment building construction site management manpower staffing standards.
