노후 주거용 건축물 비구조체 해체 시 환경유해인자 분석
손병훈,Son, Byeung-Hun 인천대학교 도시과학연구원 2021 도시과학 Vol.10 No.1
The number of old buildings older than 30 years in Korea continues to increase from 29.9% in 2005 to 38.8% in 2020. Considering the growing urban regeneration projects, urban maintenance projects, the suppression of urban expansion, and the lack of idle land in the city, the dismantling of old buildings is expected to increase further in the future. As major accidents at building dismantling sites continue to occur, related agencies are also strengthening safety management of building dismantling works. While physical safety management such as collapse and fall is strengthened, there is a relative lack of interest in the health of workers at dismantling sites due to environmental hazards. Since relevant laws stipulate that construction waste should be separated and discharged, old buildings need to be considered for environmental hazards such as fine dust, floating bacteria, and floating molds when dismantling. In this study, we intend to find important safety management elements in the management of building dismantling sites, measure environmental factors harmful to dismantling workers, and present basic data for the management of dismantling sites in the future. "Safety management" was the highest priority, followed by "dust," "vibration," "noise," "bacteria," and "smell." The perception of the importance of "physical damage prevention" with workers working on dismantling and managers managing the site came out similar, but the perception of "work efficiency" and "health disorder prevention" through environmental hazard management showed different priorities. In the process of dismantling, floating bacteria and floating mold were collected, cultured, and measured the concentration in the indoor air. The measurement was measured by dividing it into pre-dismantling and during dismantling.

The proportion of old buildings over 30 years old increased from 29.0% in 2005 to 37.8% in 2019. These old buildings were created during the absence of building-related safety standards such as fire safety performance. In the process of use, illegal changes and extensions were made, making them more vulnerable to safety. In the 1st Basic Plan for Fire Safety Policy, among the 12-Key Tasks, one is to ensure the safety of residential living spaces. Fire safety investigations are being conducted to prevent large-scale disasters such as multi-use buildings, but no investigation has been conducted at the regional district level where small-scale old buildings are concentrated. Therefore, in order to derive fire risk factors in the old building district where old buildings are concentrated, the composition characteristics of the buildings were first analyzed.

An old building over 30 years old continue to increase. Therefore, there will be more dismantling of old buildings in the future. Safety management of dismantling works is being strengthened. However, no consideration has been given to the effects of dismantling workers and their residents due to environmental hazards arising from the demolition process. Only spray and dust prevention measures are subject to inspection to minimize dust generation considering civil complaints around the site of dismantling work. In this paper, residential buildings, which account for the largest proportion of old buildings, were collected and identify total airborne bacteria and floating fungi among environmental hazards caused by non-structural dismantling work. Measurement results showed that workers during dismantling work are working in places with 4.8 times more total airborne bacteria than indoor air quality maintenance standards. Related research is needed for the health of dismantling workers.

Since 1960's, a scale of invested capital for construction industry has been increased due to economic growth, national development and redevelopment industry. As a result of that, the amount of construction wastes get drastically increased. Compared with this kind of growth, many construction wastes aren't be used to recycle by throwing away illegally on the land. In 2007, the construction wastes made up about 50% of all waste materials generated in Korea. Especially, the construction wastes feature that a large amount are generated in a relatively short time although it is relatively harmless to human. The construction wastes also could be recycled easily and could be substituted for nature aggregate. Therefore it's being emphasized of construction wastes management considering environment and recycle. In the study, we will offer the data for necessity of sorting management of construction wastes at the construction sight and standard for economical efficiency by comparing with specific two amelioration districts.
BIM/GIS을 활용한 건설폐기물관리시스템 개선방안에 대한 연구

Recently environmental pollution and resource depletion have been rapidly progressing in the world. Construction Industries discharge tones of wastes and consumes heavy resource as compared with the production activities of other industries, so it is the main reason of increasing of the Earth's environment. In Korea, as people become aware of the need of technical and institutional infrastructure for the recycling of construction wastes, they manage Allbraro system which is Total Management System in the wastes. Therefore, they promote the handling of standardized information, processing construction waste of transparency procure and promotion of the efficiency of task about the disposal of occurrence and movement of real-time construction waste. However, objective information for dismantling building did not construct in the organization of the system, so the emission of system randomly produces and discharges information of the waste. Because of that reasons, the exact value of waste abandonment is difficult to measure and recycling after waste disposal has the limit point. Therefore, in this study, advantages and disadvantages of the existing waste management system are analyzed, and we improved solution of construction building and environment of the city when BIM / GIS are utilized. 최근 전 세계적으로 환경오염이나 자원고갈이 급속히 진전되고 있다. 그 중 건설 산업은 다른 산업의 생산 활동에 비해 막대한 자원 소비 및 대량의 폐기물을 배출하여, 지구의 환경부하를 증대시키는 주요 원인이다. 우리나라에서는 건설폐기물을 재활용하기 위한 기술적, 제도적 기반이 필요함을 인식함에 따라 폐기물 종합관리시스템인 올바로(Allbaro) 시스템을 구축하여 실시간 건설폐기물의 발생과 이동에 따른 처리에 대한 표준화된 정보처리 및 건설폐기물 처리의 투명성 확보 및 업무의 능률향상을 도모하였다. 하지만 시스템의 구성에서 해체 건물에 대한 객관적인 정보가 구축되지 않아 배출자가 폐기물에 대한 정보를 임의로 생산하고 배출함에 따라 정확한 폐기량을 파악하기 힘들고 폐기 후 재활용이라는 한계점을 벗어나지 못하고 있다. 따라서 본 연구에서는 기존 건설폐기물관리시스템의 장단점을 분석하고 BIM/GIS를 활용하였을 시의 건설폐기물관리시스템 개선방안에 대해 제안하고자 한다.

The construction debris has been enormously increased since 90's because of a reconstruction and developing a new building site. Under the construction law, construction debris must legally recycle or reclaim at cost, but almost people have depended on reclamation of the illegal process to treat construction debris. Therefore, the environmental disruption and contamination have been begun the hot issue of society and in controversy with residents. With the consequence that indicates a substitute about an application of construction debris units is the most important thing for studying construction debris of quantity when the construction units are demolished. Nowadays, the area under the housing environment amelioration policies is getting rapidly old, then it is beyond anticipating reconstruction. Before construction units are demolished, generally three of four engineers investigate or predict the quantity of construction debris for two months. But this study is using the units of construction debris instead of the investigation and gets more precise data than investigation or prediction. In conclusion, the purpose of this study offers that units of construction debris can alternate the investigating of construction debris and curtail the expenses of labors and finances. Finally, those effects are going to make economical benefits covering the whole of the process of constructions.
