Recently, defect management have been considered as one of the major issues for more large-sized and complicated in domestic construction industry. However, the defect management have not been performed systematically because of special manpower, excessive amount of documents, 2D based inspection work, unclear traditional checklists, complicated work process and difficulty in communicating construction information. Therefore, the construction field manager could not performed the quality inspection and defect management work on time as well as the reliability of recorded quality and defect factors was decreased. The primary objective of this study is develop a Construction Defect Management Application CDMA) using a mobile (smartphone). The application can be sharing a huge information and communication technology based on RFID (Radio-Frequency Identification), BIM (Building Information Modeling) which enables field mangers to efficiently gather the information of defection in construction on-site.

GS E&C had developed the construction management system, PMS which is based on EVMS in 1997. Recently, TPMS has developed for effective construction management through applying daily schedule management and JIT on material, labor, equipment focusing field work. TPMS realizes "Shielding" and "Make-Ready Process" which are the main concept of Lean construction. Through this system, it can manage and plan daily field work, support the field work related material, labor, and equipment planning, and minimizes the non-valuable process. This paper introduces the concept of TPMS, and through established system, it can lead the construction culture and raise the competitive power of construction industry

Purpose: The construction of New Han-ok style public buildings is a construction that can not be seen in traditional Han-ok, and it is a construction that combines traditional wooden structure, RC structure, and steel structure. Therefore, construction different from general construction is complicated and complex. It is necessary to accurately understand the construction method of each field rather than the general construction management method and study the method suitable for New Han-ok style public buildings. Also, since the New Han-ok style public building business is the first business to be introduced in Korea, new process management is needed rather than general process management. Method: The research method is as follows. Analyze process management through theoretical considerations and analyze the differences from general construction projects. Next, we want to identify the characteristics and problems of the process control method applied to real cases. Finally, the results of this analysis suggest ways to improve process management. Result: Therefore, it is necessary to establish a precise plan from the basic design to the construction of the public building construction management. In addition, careful planning should be made so that the supply and demand of materials and the supply and demand of personnel can be achieved smoothly.

Recently, micropiling techniques are increasingly applied in foundation rehabilitation/underpinning and seismic retrofitting projects where working space provides the limited access for conventional piling methods. Micropiling techniques provide environmental-friendly methods for minimizing disturbance to adjacent structures, ground, and the environment. Its installation is possible in restrictive area and general ground conditions. The cardinal features that the installation procedures cause minimal vibration and noise and require very low ceiling height make the micropiling methods to be commonly used for underpin existing structures. In the design point of view, the current practice obligates the bearing capacity of micropile to be obtained from skin friction of only rock-socketing area, in which it implies the frictional resistance of upper soil layer is ignored in the design process. In this paper, a new micropiling method and its verification studies via field installation are presented. The new method provides a specific way to grout bore-hole to increase frictional resistance between surrounding soil and pile-structure and it allows to consider the skin friction of micropiles for upper soil layer during design process.

The top-down construction method is an excavation and substructure construction method by excavating earth and building slabs from the ground level to the bottom of a building. The top-down method can be categorized into several types by its process and other technical details. Some of commonly used top-down methods in Korea today are S.O.G., N.S.T.D., and S.P.S. Among these, one method is chosen depending on construction field conditions, cost, construction time and so on. This study explores several factors that may affect the selection of a top-down method. This paper reports preliminary survey results with 54 top-down construction experts and comparison results of 5 top-down construction sites.

Steel frame construction is divided into subsidiary materials with column, beam, girder and bracing. After these are processed in factory for using installing in construction field. These prefabricated furniture is very important in accordance with design drawing about processing and prefabricating. In the case of design process using information transmission in blueprint, omission of material number, processing measure and finishing material, or discordance of each structure drawing and selecting incongruent structural material generated an error in the process of design. These error caused delaying tine and increasing cost and increasing safety accident in the steel-structure work operating process. therefore, design process should consider problem of operating process.

This study analyzes the current educational curricula in the field of clothing construction to provide some fundamental information for developing more appropriate educational courses and to activate the fashion business. A total of 82 different departments related to fashion and apparel were selected from four-year domestic universities and the curricula recently posted on their internet websites were analyzed by descriptive statistics. More than half (53.7%) of the 82 departments were offering classes in the clothing construction field for 3 credits and 4 class hours. College affiliation of the departments that offered curricula in the clothing construction field was classified into 5 categories: the arts (34), human ecology (22), natural sciences (14), humanities/culture (9), and others (3). Human ecology category showed the highest results in the average class hours (3.9), the number of classes in the clothing construction field (7.6), and the percentage of the classes in the clothing construction field out of all major classes offered by the clothing department (19.9%). All 82 departments were classified into 3 categories of: fashion design (32), clothing (28), and fashion business (22). The clothing category showed the highest results in the average credits (2.8), class hours (3.8), the number of classes offered by the clothing construction field (7.6), and the percentage of the classes that offer clothing construction education out of all major classes offered by the clothing department (19.9%). The educational contents of clothing construction area were classified into 8 different categories of: basic theory and sewing, clothing construction, flat pattern, draping, tailoring and advanced clothing construction, pattern CAD, sewing science and apparel manufacturing process, and clothing construction for special needs. Among these categories, the draping category constituted 21.7% as the largest part. In addition, the distribution of classes offered by 4 academic years were analyzed into 8 different categories.

Construction industry has become higher, larger and more complicated. It has been analyzed that the process planning in the construction site has been made by the site engineer experience mostly and some were made based on historical data. However, such plans have been investigated that require numerous revisions during construction which means that the plans made through such methods are not reliable. Numerous studies in this field have been conducted trying to solve such problems developing methodologies to overcome such limitations. It has been analyzed that many studies have focused on suggesting prediction models only that cannot be used for both actual planning prior to construction and process monitoring during construction. Therefore, this study suggests a methodology that effectively manages construction productivity by applying simulation methodology combined with bayesian approach focusing on the high-rise curtain wall operations.
