Recently, the government is pursuing to reduce the serious accidents in most industries, including the construction industry, by enacting laws on punishment. The accident rate tends to be depended on the size and type of construction sites, and the accidents occur frequently due to inadequate implementation of safety management system and management standards, especially, in small and medium-sized sites. This study has performed the profiling of 265,000 accident cases on construction sites by attribute analysis such as the ratio of days lost to work, and pattern of days lost to work compared to the size of the construction. It turned out that the proportion of accident cases was high mainly in small-scale construction sites, and long-term labor losses occurred. Shortly, it is necessary to establish an institutional standard for applying a realistic safety management cost calculation and management system centered on small-scale sites. Therefore, this study is expected to be used as fundamental data or guideline for developing a customized safety management and accident prevention system for a worker reflecting the conditions of a construction site in the future.

Purpose: Small-scale construction sites have insufficient systematic safety management activities, and due to the characteristics of the construction site, the production structure is complex due to external environmental factors, and the risk of construction equipment is very high. We would like to propose a checklist method among practical risk assessment techniques that can derive risk factors for disaster prevention at small construction sites and reduce disasters. Method: Risk factors were derived by analyzing literature research and disaster cases, and detailed work for a checklist of risk assessment suitable for small-scale construction sites was classified based on risk factor items. Result: Hazard factors were divided into 6 major categories, and 29 detailed types of work were classified based on actual work types, and 80 detailed works were classified accordingly. Conclusion: By arranging risk factors suitable for small-scale construction sites according to the classification system, the lack of expertise in the construction site can be supplemented, and risk factors can be derived more easily and disaster reduction can be expected through establishment of safety measures.

This research aims to identify risk factors for fall accidents at small and medium-sized construction sites through a comprehensive regression analysis. Initially, the study involved collecting a decade's worth of fall accident data from these sites. A t-test confirmed a significant variation in the treatment duration following fall accidents between two distinct groups: small and medium-sized versus large construction sites. Subsequently, a regression analysis was conducted to establish a model highlighting the risk factors associated with safety accidents. The factors influencing fall accidents were determined to be, in descending order of impact, the time of the accident, the day of the accident, and the occupational classification. The findings from this study are expected to serve as foundational data for enhancing policies and conducting statistical analyses tailored to construction site sizes. They also provide crucial information for future research on risk quantification at small and medium-sized construction sites.

The construction industry generates the greatest number of disasters. Laborer injury at construction sites is mostly reported by small and mid-sized construction sites. Moreover, of the injuries, the greatest number is related to formwork. The objective of this study is to propose a checklist of the risk factors of formwork, in which industrial injuries occur most frequently in small and mid-sized construction sites, with which safety management can be done thoroughly. Risk factors and preventive measures are derived by analyzing 9,396 industrial disasters occurring at construction sites in Korea. The checklist drawn in this study was reviewed by five specialists in safety management, and applied to construction sites to verify its applicability. In a result, applying the checklist to the site showed that the safety management system of small and medium-sized construction sites were insufficient. It is expected to contribute to the effective safety management of small and mid-sized construction sites.

Since 2004, the government has changedthe cost estimate system to one of an actual cost basis in order to calculate the optimum construction cost by reflecting changes in circumstance on the construction site in a timely manner. Currently, this is being applied to public construction work forover a billion won of actual cost data in estimation by contract unit cost. However, directly reflecting actual cost, which for large-sized construction work was originally an average unit cost, to a small building, entails the application of a low discount rate for the cost of materials, labor, etc. and therefore can frequently give rise to cases in which the actual cost of work performed exceeds the contract sum, which in turn causes problems such as decreased revenues, bad effectson business operation, productivity, etc. Therefore, to apply actual cost to small-sized construction work (less than a billion won), there should be a plan to modify unit cost in a manner that can reflect project scale, etc. in order to resolve the problem of unit cost application of actual cost to small-building construction projects. The unit cost modification model for proper actual construction cost in small-scale construction projects developed by this study will help to increase the relevant productivity and proper gain, preventing the aggravation of business operations. Organizations placing orders are also expected to be able to secure a more realistic construction cost in arranging the budget.

"Act on Facilitation of Purchase of Small and Medium Enterprise - Manufactured Products and Support for Development of Their Markets" was created and implemented. The act states that the materials designated by the Small and Medium Business Administration are directly purchased from the small and medium enterprises and provided to the construction companies so that the materials can be provided as GFGI (Government Furnished and Government Installed) in the case of a public construction project. This thesis is aimed to analyze the current status on the problems of each project party and understand their improvement requests so that mutually beneficial plans can be sought and improved process is presented for the continuous development of the direct construction material purchase system as well as successful construction projects. And This thesis summarized the purpose of the institutions and their change histories, and related law as well as codes for the better understanding of administrative procedures for the purchase system and the analyses as well as the improved process on the difficulties in complying with the current institutions.

The building below standard scales to be built only by constructive report to authorities. Construction law 8 illustrates that supervision should be deployed in all the construction sites at the building which is found to have more than 3 floors and also to have more than loom of total squares in especially outside area of city plan zone. Such a small construction is have a important and the most basic meaning. Many problems were found to occur in all the constructive places which were out of the limit of this law. The construction sites were found to be controlled by public official's visiting without supervisors and designers of architecture. Technique of construction in architecture was found to be not different from that of 1980. The security of employees in construction on sites has a serious problem. Because of choosing ail the materials of the building without a reasonable point. All the building were found to have a law material about inside and outside aspects. The purpose of this study are to examine existing law about a small project and than to analyze the situation of constructive control through questionnaires and interviews with all the supervisors. Based on the data base of engineers who had a great experience in construction sites, The purpose of this study is also to suggest and advise the method of controlling all the items in architecture through on and off line.

"The Law of purchasing policy for market support of small and medium business" was legislated to support small and medium industry by expanding purchase and revised consistently for the activation. And then the government made the public construction direct purchase compulsory about design items designated by president on small and medium business based on this law. However, secureing quality, tardiness and field material staff's heavy duty were arisen from approximately 120 direct market purchase items. The legislative intent of law is in accord with Win-Win growth between major company and small and medium business. However material staff who works in the field based on this law has difficulties with material securing quality, JIT(Just In Time), cost push. This study reclassified procurement items of "the direct market purchase system" reasonably and then suggested performance criteria for evaluation. The suggested result will contribute to vatalize the direct market purchase system.

As public concern for fine dust has increased, so too has the interest in fugitive dust. Fugitive dust generated at construction sites, which is then scattered by vehicles moving around the sites, accounts for a significant portion. Small construction sites, which comprise the majority of construction sites, are often not adequately managed, because there are no regulations on fugitive dust for such sites. Therefore, in this study, in order to contribute to the establishment of fugitive dust management regulations on small-scale construction sites and to prepare measures to reduce fugitive dust, we measured and analyzed fugitive dust generated at small-scale building sites in Seoul. The fluctuations of fugitive dust generated at small-scale sites over time were checked, and the relatively low concentration when measured behind fences and railings suggested that fence installation is an appropriate method of reducing fugitive dust.
