  • In recent years, pollution in residential spaces has been a significant area of concern. In particular, the indoor air quality (IAQ) of an apartment building before occupancy, which is related to the interior material, is a serious problem. Unlike previous research, which has mainly focused on pollution control after construction, this study has derived influencing factors and priority of management with a controlling schedule for IAQ. The objectives of this research are 1) control of schedule or improvement of management for IAQ, 2) distribution of responsibility to the parties concerned (factory, material company, construction company, design and engineering, occupancy). The results show the relative priority of the four major items in wall?based apartment buildings and in column?based apartment buildings. An analysis of the parties responsible for improvement based on the IAQ results shows more efforts to improve IAQ are needed in material factories and engineering/design companies.

  • Currently, the quality management, safety management and environment management of domestic construction work does not form a infrastructure for integrated control which have been developed according to the unique characteristics based on respective the law. In other words, the quality manager and safety manager of human resources is set to a legal arrangement personnel, but environment manager of human resources is not. In addition, quality management standard is to perform the work to PDCA(Plan-Do-Check-Action) system which is reflected in all of the requirements of KS A ISO 9001 standard, but safety management plan and hazard harmfulness prevention plan are not properly reflected P(Plan), C(Check) and A(Action) system and focusing on only 4 section Do(D) in KOSHA 18001 standard requirement. Moreover environmental management plan is not even established requirement. Through examining the operation practices of an advanced nation prior to building the integrated control standard for construction work qualify safety.environment, the possibility of applying domestic is reviewed, and then this study is going to research the operation practices of Singapore.

  • As domestic buildings have been large-scaled, diversified and high-rise, there have been a consistent demand for design, development of construction technology and accident prevention activity as well as quality enhancement. In spite of governmental and related institutions' efforts for reducing national losses which come from numerous accidents, there have been endless small and large accidents on the construction site and thus, it is urgent to conduct empirical researches in this area. Currently safety supervision system in construction industry has enforced harm and danger prevention planning system, however it merely stick to other existing materials. In addition, it is difficult to put it into practice in that it requires bearing too much burden to draw out the planning itself in a case of large construction work. Consequently in this paper we select evaluation criteria by construction progress, classify into several categories, and regard potential danger which often occurs, as a evaluation criterion. Further step is to allow workers or collaborated companies to express their expert opinions or experiences and to encourage quality and process control and autonomous safety control by applying PSM method. The reason why PSM method should be quantitative and substantial progress is because it contributes Korean constructing companies to enhancing their safety control ability and to taking an equal stance just like developed countries,' thereby strengthening there competitive edges. Boost of safety control system by PSM method will make an enormous contribution to preventing construction accidents on the site by establishing and securing an autonomous safety control system.

  • This study is to find out primary factors through the punch list in the large scale apartment housing complex, to prevent repeatedly occurring defects of construction and to gain quality management. The following are the findings of the research. (1) The positive strengthening of supervision for the workers can contribute to prevent defects of apartment construction and make better quality of the construction. (2) A solution should be made for the poor of surface join and the damage of work element showing a lot in the apart construction, which prevent defects and improve construction quality. (3) Indirect factors such as negligence and carelessness of the management should be improved to advance construction quality, and the caution and control strengthening of the management should be followed. It is revealed that hitch, omission, and heedlessness come from the defects, and the shortage of skill and checking appear as indirect factors. Therefore, to get quality improvement, the enhancement of the management factors, employment of excellent workers, and enhancement of working attitude and construction management are needed.

  • This paper presents a strategy for the quality assurance of the continuous preflex composite girder bridge through the camber management of the girder during construction. The construction stages which require welding, balanced preflexion loads at the ends, etc. may cause unexpected large deformation to the preflex girder. Furthermore, these defects can be detected by measurements and analyses of the girder behavior which is sometimes time consuming. In the present study, preflex girder's camber data at equally spaced nodes in each construction stage are obtained and analyzed for the quality control of thee span continuous preflex girder composite bridge.

  • According to the statistics publication of KOSHA, more than half of serious accidents at the construction sites were related to the temporary works and/or the temporary structures such as scaffoldings, shores, earth retaining walls, etc. The structural failures are occurred because of the overload acting on the structures or lack of performance of the one or more members of the structures. For the prevention of the collapse accidents relating to the temporary structures at the construction sites, we have to control construction processes not to occur the overload and also to control the performance and quality of each member of the temporary structures. MOLIT has amended the "Construction Technology Promotion Act" on Jan. 7th, 2015 to ensure the structural safety of the temporary structures. According to the Act, the designers of the construction design projects should check the structural integrity of the structures including the temporary structures and the construction companies have to let 'the Relative Professionals' confirm the structural integrity of temporary structures, the shores(${\geq}5m$ high) and the scaffolds(${\geq}31m$ high), before construction. Also, MOLIT has amended the "Regulation for Construction Technology Promotion Act" on Jul. 4th, 2016 for quality management and testing of temporary equipments. According th this regulation, the construction companies and supervisors should manage and test the temporary equipments before using them. In this paper, the standard drawings of the shores(< 5 m high) and the scaffolds(< 31 m high) and the amended "Business Guideline for Quality Management of Construction Work" are presented. As the result of this study, MOLIT noticed the amended "Business Guideline for Quality Management of Construction Work" on Jul. 1st, 2017.
