The amount of construction waste increased to 176,447 ton/day in 2008 from 28,400 ton/day in 2000, a 6-fold increase in just 10 years. Such dramatic increase in the waste of concrete, asphalt concrete, wood and metals was due to demolition of old buildings as well as a great number of building redevelopment projects and hurried city industrialization. Many buildings targeted for demolition today were built in line with the government policy to provide affordable housing to citizens in the shortest time possible and consequently, said buildings underwent rapid deterioration and required periodic repairs and reconstruction. Based on the above, we predict that construction waste will continue to increase for the foreseeable future. In particular, due to limited availability of suitable space to construct apartments and residential buildings in the city, old buildings are being torn down to make space for new development, further increasing construction waste. In light of that, efforts to recycle as well as reduce generated waste are urgently required.

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.

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.

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.

Buildings are aging depending over time. This means that the fire evacuation safety performance degradation according to aging. Especially commercial buildings need to a fire and evacuation performance critical because commercial buildings have a lot of fire risk compared to the building for other purposes. Therefore, the purpose of this study is to present a method which can improve the performance of the effective and reasonable safety evacuation by the manager in the worn commercial buildings. In this study, we presented a concept for the effective performance improvement. This concept is intended to present the priority for performance improvement suitable for each of old commercial buildings. In the future, the research results will be able to use decisionsprogram to improve the safety performance in the old commercial buildings evacuation.

Asbestos have been used around the world by physical and chemical characteristics that are a reliable and cost-effective. But asbestos, once called the miracle of mineral, is now a quiet time bomb. Asbestos hazards have been studied and the government has pursued 'Comprehensive Measures for Asbestos Management' jointly with related departments. As a part of plan, Ministry of Environment is to introduce legislation 'Asbestos Safety Management Act' through Environment Announcement No. 2010-108. The same Act. 24 shows as follows. Minister of Environment or governor should do survey on the actual condition targeting rural buildings with slates and partly or fully fund to dissolve, remove asbestos slate which was used in each building. However, the local survey was only conducted by each municipality regionally. And there is no actual condition data by area, application and year, and there was no data on disposal costs concerning asbestos slate buildings In this study, discharge of asbestos slate was calculated per unit area and formula was developed with regression analysis. In addition, Demolition, dismantling, disposal costs were computed via a phone survey to disposal companies and then this study proposed standards for this.
