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.

This paper presents the findings obtained from the investigation of fatal disasters occurred by small-sized construction firms which have been accepted as to provide lower safety performance other than large-sized construction enterprises and cause more than half of the safety accidents in average. The study identifies the current status of safety performance provided by the small-sized construction contractors in details, find the issues involved with lack of safety performance, and suggest the improvement measures derived from the findings. A survey questionnaire was administered to the construction contractors, which are listed in the database of Construction Association of Korea as to fall into rank between 501st and 1000th in construction capacity. Safety issues such as the performance of safety management system, safety control structure, safety cost relative to safety control, education devoted to safety improvement, usage of safety garments or individual protective tools, and activities to maintain safety performance on site, etc were investigated from the study.

As the quality of life has been improving, people are getting higher interest and higher expectation for safety. However, the accident rate at the construction site is still high. Therefore, it is urgent to secure the safety at the construction work. Due to the nature of the construction industry, construction sites are directly exposed to the external environment. The possibility of accident occurrence is increased due to various factors such as the always variable processes, the diversity of manpower input, the increase in vulnerable class, and the danger of construction equipment..Particularly, the disasters occurring at the small- or medium-sized construction sites (budget ≤ 12 billion KRW) account for 88.9% of the total disasters at construction sites (73.4% for casualty). It was due to the lack of management caused by the absence of supervisors and insufficient safety measures. Moreover, it is difficult for the small- or medium-sized construction sites to apply basic safety measures such as safety education and safety facility installation by themselves in order to prevent disasters because they don't have sufficient safety organizations. It is because they have relatively less safety personnel and poorer technology system than large-sized construction sites. Therefore, in order to reduce accidents in construction, it is necessary to prevent accidents at the small- and medium-sized construction sites. From this point of view, the objectives of this study were to identify the key risk items causing accidents frequently by analyzing the accidents at construction sites and identifying problems associated with safety management, and to secure the safety at the small- and medium-sized construction sites.

Recently, industrial accidents rate has been gradually decreasing due to the development of safety management methods, but until now, the accident rate in the construction sector is higher than other industries. Large-scale construction sites are operating systematic safety systems to reduce industrial accidents. However, small and medium sized construction sites do not have systematic safety system and lack safety management ability, so that disaster is not reduced compared with large scale construction site. As a result, disaster prevention technology instruction system has been implemented to reduce the disasters of small and medium scale construction sites. However, in the case of a small construction site less than 2 billion won, there is little decrease in the accident rate, and in some cases, the accident rate increases. After the technical guidance system has been implemented, it is necessary to identify the performance and problems of implementation and to improve its effectiveness. In this study, we suggest the improvement plan to improve the efficiency of the technical guidance system by analyzing the problems and actual conditions of technical guidance operation in small and medium sized construction work 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.

This study is to analyse the causes of accident in small and medium-sized construction sites and to provide prevention strategies and system improvement guidance. Although occupational safety and health act regulates the standards and installations of temporary structures, about an half of construction accidents were caused by poor temporary structures such as guardrails, scaffolds, work platforms, etc. It investigated 51 construction sites which is located in metropolitan area by asking a series of questions including their knowledge about regulations and opinions about prevention strategies. The result shows that many of the respondents do not have sufficient understandings about the regulations, and it implies that education and training must be reinforced in order to enhance the safety-awareness and to develop the comprehension of regulations.

Since February 2017, site managers in small architectural projects are required by the revised building act. In order to address issues for site managers and to improve project efficiency, system improving methods are surveyed and proposed in this study. The key inspection items in the existing surveillance guidance manual were investigated, and the checklist for site managers for a small to medium sized construction site was analyzed. This study also tries to propose using web-based site management systems for improvement of the utilization of checklists. It is expected that these on-site management systems, along with BIM technology, will be able to monitor the small size building construction project in real time and effectively monitor the various problems occurring on-site.

The purpose of this study is to investigate the seismic performance of exposed column-base plate strong-axis connections for small-sized steel buildings. Even though the seismic design for small-sized buildings became mandatory since Dec.2017, the arbitrary connection details in steel structure have been applied at the construction site, which is considered to be very insufficient to secure structural safety and stability considering the increased seismic risk. Therefore, a series of experimental test programs had been carried out to develop enhanced connection details in order to ensue the adequate seismic safety of small buildings. The hysteretic behavior of the exposed column-base plate connections commonly used in Korea seem to be very pure poor due to the "Rocking" phenomena between anchor plate and concrete by the residual plastic deformation of anchor bolts. A series of hysteretic tests were conducted to find the solution to overcome the "Rocking" phenomena of the exposed column-base plate connections, finally the stable seismic behavior was obtained by uisng at least 8 anchor bolts with good bonding strength to the protptype specimen.
