In the pilling works in the city, it is tend to transfered to the non-vibration pilling works. This drop-hammer pilling executed with in 2 meters distance to neighbour building structure. in the rainy season. According to imperical formula which tested in similar site, Vibration damaged area is within 14 meters radius from drop-hammer pilling site. The loratories Data of Dae Woo of Korea hausing Authority are refered to above poject.

Recently, It is a fact that the percentage of female field managers has increased in the construction industry. Therefore, this study investigated the percentage of female construction site managers by conducting a survey of current male and female construction site managers and then analyzed the workload, work difficulty, work importance and performance level of female employees in charge of public affairs, which is the most common tasks.

When measuring fine dust at a large-scale site such as complex construction, the change in the value of fine dust measurement is large due to the influence of the time, location, wind speed, wind direction, and humidity. This study aims to find out the results of measuring fine dust in an actual construction site and inferring the changes.

Recently, it is necessary to establish an eco-friendly construction system through recycling of waste material management at construction sites. This is required to reflect the times that require a carbon reduction system in construction as part of domestic and overseas carbon dioxide reduction. Therefore, we intend to establish eco-friendly construction management as part of resource recycling and carbon reduction through recycling technology for waste fibers generated at construction sites.

In Korea, the apartment buildings have been constructed recently in large quantities to provide housing due to the gravitation of population towards large cities. However, because of this trend toward high-rise apartment, a number of problems are occurred such as the deterioration of comfort in the dwelling environment and the lack of solar access right in apartment buildings. In the building law, the sunshine hour and the minimal separated distance between apartment buildings as regulated as the criteria for the site planning. Most of site planners, however, designed the apartment site only following minimum separated distance. As a result, the problem of sunshine hours lack is caused and legal dispute concerning solar access right is also arisen. The purpose of this study is to improve solar access right regulation and to help site design of apartment planning. Accordingly, we execute empirical analysis based on computer simulation in order to find suitable separated distance between typically designed apartment buildings. First, we estimated sunshine hours according to independent building orientation, height, and length. Second, we calculated sunshine hours in various case of apartment arrangement; parallel type, courtyard type, tower type and etc. with various separated distance.

As the number of Web reference resources are gradually increasing, reference librarians have to create a Web-based reference resources site. This site includes links to the Web reference resources of good quality, so that reference librarians and users will become accustomed to using these resources. This Study first explores the function of the Web-based reference resources site. Next, it carries out a survey of the current trends in america and Korea. Finally, a model Web-based reference resources site for academic libraries is developed.

In MCDA (Multi-Criteria Decision Analysis) based on GIS, building the CM(Criteria Map) which represents the space phenomenon properly is important process to deduce precise and efficient site analysis result. The CM using administrative district data is widely used for site analysis process. But, there are not enough studies on site analysis using dasymetric mapping technique. For MCDA, this study suggests building the CM by using dasymetric mapping technique, which re-assigns the social-economic attribute value to more detail space unit. The suggested method is used for industrial site analysis. The criteria map for workforce and criteria map for the distance to the city were built and criteria map which represents attribute's space distribution pattern is documented. The criteria map is successfully applied to multi-criteria decision making process and eventually the analysis result of proposed suitable industrial site is derived.

The purpose of this study is is to organize the site-plan types of common design's Goon office buildings in Japanese colonial period based on the main building's shape and main & attached building connection way and to investigate all the types' addition & remodeling ways. The study used literature research method, analysing the digital images, the annotation of the images, official documents between the Japanese government-general of Korea and To, and articles of newspapers or journals. The site-plans are sorted 5 types and subdivided 13 as their addition & remodelling ways. The initial shapes of site-plan were changed to apply every Goon's site circumstances, The main buildings were always in the center ahead and attached buildings behind or next to them in any cases of new construction, addition or remodeling. The buildings of the common design's were constructed until early 1930s and it means that their architectural level was lower than Pu office buildings, although both had same administrational level.

This study aims to develop a performance evaluation system for the Construction Factory(CF). The CF is a kind of full automation system for building construction which consists of the lifting system for building materials, the built-up unit for steel structural components, the bolting robots, the control center for the site management, and the site covering system. The CF is developing now as a project of the construction automation and robotics. In this study we firstly reviewed the state-of-the-art of the construction automation and robotics in the foreign and the domestic, and investigated the precedent case of the CF such as the SMART System of Shimizu Co., Japan. We believe that without an objective evaluation of the results there won't be growth in technological R&D. Therefore, this study sees the developing CF as an new technology and method in building construction, and proposes the direction and frame of the appropriate evaluation which can be applied into the CF.

Building Information Modeling (BIM) and modular construction are regarded as important technologies that address several issues faced by the construction industry. However, the application guidelines for BIM in current modular construction projects are insufficient. This paper presents the preliminary work on the analysis of BIM utilization in a modular construction project; a five-point likert scale questionnaire was conducted to assess the necessity of BIM applications by the Necessity Index(NI) of nine categories(U1~U9) across two construction phases (onsite and offsite). The survey results indicate that applications for BIM based quantity takeoff for offsite phase(U4) as well as BIM modeling for module joint details(U8) were deemed to be the most necessary in each phase. The results of this study can be used as detailed guidelines for the integration of BIM in modular construction projects.
