The government has routinely made efforts to improve the living environment and infrastructure of less-developed areas through large area urban remodeling projects, which are in themselves attempts to overcome the disadvantages of piecemeal local area development. Such projects are very complex, and various stakeholders are involved. However, the data on such projects has not been well managed, and has not lent itself to being easily adopted to similar projects. In addition, there are numerous fragmented mega-projects that seem to be performed based on "rules of thumb" To address this issue, the work process of many urban and residence project types should be standardized otherwise the participants will be confused to work properly. In particular, typical residents who lack knowledge about building redevelopment, building remodeling, urban environment improvement projects, and the like think that it is difficult to establish the preparation committees and association committees for the projects. Therefore, we examined previous researches related to the urban and building renovation to solve the prescribed present problems. This paper presents the three necessary research performances: first, we analyzed the administrative work process in the related laws; second, we examined the practical work process of the preparation committee and association committee stages; and finally we deduced the problem and presented the required improvements.

DOI : 10.5345/JKIC.2010.10.3.049
The purpose of this study is to examine the effect of variations in the mix rate of PVA fiber and the replacement ratio of non-sintering Hwangtoh on non-sintering Hwangtoh mortar and concrete mixed with PVA fiber. For water to binder ratio, mortar and concrete were both 50%, and PVA fiber mix rate was 0% and 0.3%. The replacement ratio of non-sintering Hwangtoh was 0, 25, 50 and 75(%) for mortar, and 0, 15, 30 and 50(%) for concrete. The properties of the mortar and concrete were compared and analyzed in 4 different levels, and the results can be summarized as follows. The replacement ratio of 30% of the non-sintering Hwangtoh, and the PVA fiber mix rate of 0.3% is determined to result in concrete of high quality, including strength and fluidity, and crack control by plastic shrinkage.

This study is to analyze the effects of aluminum form surface coating material on surface quality of concrete. When observing the surface quality of concrete affected by the change of aluminum form surface coating material, in general, as the number of use of the coating material increased, the surface quality of concrete decreased and good surface quality was shown in plywood (hereinafter PW). For epoxy (hereinafter EP) resin, when applying form remover, good surface quality was shown. For the surface roughness of concrete by the application form oil of form remover and the number of use of the coating material, as the number of use increased, highest surface roughness value was shown which meant the leveling was bad, but the surface roughness value in EP and PW was the lowest. Just for EP, when applying form remover, surface roughness value was low. For the number of void for concrete by the application of form remover and the number of use of the coating material, In general, the number of void which was generated when applying form oil the remover decreased.

Steel frame construction in high places entails many risk factors. In order to improve the safety and productivity of steel frame construction, a project to develop a robotic tower-crane has been undertaken. As the first step, a real-time lifting-path tracking system is being developed. In a previous study, a laser-based tracking system was proposed. While a laser-based tracking system requires at least three laser sensors to detect the x, y, z coordinates of a lifted steel member, a GPS-based system has an advantage over the laser-based system, in that the x, y, z coordinates of a lifted steel member can be detected by a single GPS sensor. To improve the accuracy, arelative positioning method using two GPS sensors was proposed in a previous study. This paper reports an improved GPS-based lifting-path tracking system of a tower crane based on an integrated RF modem and GPS system. The results showedthat the RF modem could successfully send the identifier information to a server a maximum distance of 1 km away from the lifted steel beam, and the lifting path information of each beam captured by the GPS-based tracking system was successfully saved together. Also, byusing an improved algorithm for the GPS relative positioning method, the deviation was reduced to 0.61 m on average.

In 1994, Korean construction research and development (R&D) projects received investments amounting to 1.2 billion KRW, an amount that rose to 164.8 billion KRW in 2007. Under the current system, construction researchers submit the application records of Construction Research and Development (R&D) in construction projects to the Korea Institute of Construction & Transportation Technology Evaluation and Planning. The performance of Construction R&D projects has thus been dependent on the subjective reporting of the results by the researchers themselves. For this reason, it is difficult to secure confidence in the records of Construction Research and Development. Therefore, this research suggested measures for revitalizing Construction Research and Development, analyzed approaches to cost-saving in Construction Research and Development, and analyzed economic effectiveness in the results of construction R&D.

The carbon dioxide(
) emissions that result from construction are one of the main factors causing a global warming problem. It is therefore necessary to make efforts to reduce
emissions in the construction industry. Some researchers have studied
emissions in the industry ; however, there has been a lack of study on
emissions cost. Therefore, in this study, the construction costs, including the
emission cost, of masonry wall type, which is a common brick wall, concrete brick wall, and fired brick wall, were examined. The purpose of this study is to compare the construction costs of masonry wall types, including
emission costs. The study found that the
emission costs were highest for the fired brick wall, followed by the concrete brick wall. This research could provide basic information that can be used in other engineering methods to convert

Recently, as a countermeasure to the buoyancy of a building, the use of permanent drainage methods have been on the increase, and these provide benefits both in terms of economical feasibility and efficiency. When a permanent drainage method is applied, some underground water can drain out. Korea has been designated by PAI (Population Action International) as a water-stressed country, and the use of outflowing groundwater is required for the efficient oversight of water resources. However, the evaluation process on the practical use of underground water is currently insufficient. Therefore, the amount of outflowing groundwater put to practical use and the standard for the water quality were examined in this research, with the aim of establishing anappraisal process on the practical use of underground water drainage. In addition, standards for the assessment of the treatment process and the application cost of underground water drainage were developed. On this basis, an evaluation process on the use of outflowing groundwater was developed and applied inthe field. The application result proved that it was possible to assess the initial investment cost and the maintenance and management cost in the field, and thesecan be compared to the costs when supplied water is used, which makes it possible to apply in the field.

In recent years, the number of high-rise building construction projects has grown, and the number of construction safety accidents has also been increasing. Therefore, the objective of this study is to propose plans to prevent accidents by systematically organizing accident principles and developing a tree diagram for the process of safety accidents that occur in the construction industry. This study aims to show the diverse characteristics of construction accidents based on KOSHA's annual reports on safety accidents(burial, conflagration, explosion, burn) from 1993 to 2009. To achieve these objectives, in this study we first examined the risk factors for burial, conflagration, explosion, and burn. We then systematically organized the classification viewpoint of accident causes, and suggested a methodology for the rationalization of safety management through an analysis of the primary causes of accidents by work type. The results of this study based on this methodology can be divided into three areas: 1)the types of facilities were divided into 43 categories by analyzing the information of KOSHA's annual reports; 2)the causes of burial, conflagration, explosion, and burn were divided into 63types; 3)the types of work were divided into 29 categories.

Ultra-High Strength Concrete (UHSC) demands a clear presentation of its mechanical properties, as distinct from normal strength concrete, and an evaluation of the serviceability of high-rise buildings that use ultra-high strength concrete. Ultra-high strength concrete fck=150MPa was manufactured with pre-mix cement, and an experimental study was conducted to evaluate the mixing properties and compressive strength, with the major variables being unit cement contents, water-binder ratio, and type of pre-mix cement. The test result showed that 150MPa concrete requires about 6~7 minutes of mixing time until each of the materials (ordinary Portland cement, silica fume, blast-furnace slag powder and anhydrite) are sufficiently revitalized. The slump flow of fresh concrete was shown to be about 700~800mm with the proper viscosity. The average value of concrete compressive strength was shown to be about 70% in 7 days, 85% in 14 days, and 95% in 28 days, for 56 days of concrete material age.

Journal of the Korea Institute of Building Construction, volume 10, issue 3, 2010, Pages 129~136
DOI : 10.5345/JKIC.2010.10.3.129
This study is an evaluation of the water-tightness properties of rain-block systems in the sliding-roof joint of large-span membrane structures. In this study, we suggested a method of evaluating the water-tightness performance of the joint part of a sliding door in the roof of a large-span membrane structure (for a pilot project), in an environment of rain and wind. The shape of the rainwater blocking systems of the joint part in a sliding door verifies the defects and the effects of water leakage prevention when there is precipitation with wind conditions. To secure the water-tightness of large span membrane structures, it is necessary to have a guideline on the evaluation of the design for rain-block system of the joint part, and the quality of the membrane material, both of a retractable roof and a closed roof.

As mega-sized and complex building construction projects are on the rise, the importance of project scheduling and control is being highlighted. Project scheduling and control techniques are not yet widely used in Korea, but interest in these has progressively been increasing. Until now, most research projects have mainly focused on scheduling issues, but project progress management is of equal importance. In this research, the current state of project progress management in Korea is analyzed, and ways for improvement are suggested. We begin by analyzing previous research and practical studies in this field, and then survey experts about the current state of project progress management. This study suggests the Building Information Modeling (BIM)base project progress management method for quantitative and qualitative project progress analysis. Currently, BIM is applied to design, construction and maintenance for construction projects. BIM can also contribute to improving accuracy and understanding of the current project situation.

Public institutions and owners have been introduced to Building Information Modeling (BIM) tools. BIM has become an important factor in the design process in undergrad programs. The purpose of this study is to demonstrate the improvement of the architectural engineering design process through an analysis of BIM courses. BIM education courses are analyzed to compare the level of detail in BIM education. An architectural engineering design class needs to involve BIM in the introduction of an integrated design process. An architectural engineering design process needs to be based on understanding design, building structures, construction and building services. 3D Modeling helps support an understanding of building structure and eco-friendly element analysis. The new process of architectural engineering design education is proposed as a result of this research.
