  • Safety-conscious design on site is required for site constructions because of the introduction of the design for safety, but it still leaves much to be desired. This study compared the site where the design was applied and the site where it was not applied. The applied case examined the underground wall construction during frame construction, which corresponds to the skeleton of the building construction. The underground wall construction is quite risky due to the exposure to exterior environments and involvement of various stages, such as scaffolding, formwork, reinforcing work, and concrete casting work. Therefore, the risk factors for each stage were identified and a risk assessment was carried out to select an alternative method to reduce the risk. The risk factors of the selected alternative construction method were also identified and a risk assessment was conducted. The risk assessment weight was calculated by comparing the site where the construction method was applied and the site where it was not, explaining the necessity of the design for safety in reducing the risk. In addition, an actual case where an alternative construction method was used was studied to highlight the necessity for a design for safety.

  • On January 8, 2021, the Act on the Punishment of Severe Disasters passed the Legislation and Judiciary Committee and has been in effect in earnest since January 2022. However, safety accidents at construction sites are still continuing, and it is necessary to discuss ways to improve the safety awareness of construction workers. Therefore, in this study, data were collected through a survey of construction site workers, and the effect of the organizational climate of the workplace on the level of safety consciousness of workers was studied. As a result of the study, the factors of organizational structure, guaranteeing autonomy and consideration of supervisors among the organizational climate of the workplace had a positive effect on the improvement of workers' safety awareness. Based on this, this researcher suggested that workers should be delegated the authority to perform some tasks according to the situation and content of the work during the field work and that incentives should be compensated according to performance.

  • The law(construction standard specification, construction, standard-work regulation, Industry safety standard related regulation) related to the installation of scaffolding being used commonly on the construction site is regulated that the gap of ledger is within 1.5m and first ledger is within 2m. The gap of ledger here is essential for the stability of scaffolding structure. But it is determined that it is possible for the gap of ledger is applied by explaining safety handrail as ledger, because of the fact that in current, on the construction site, safety handrail is installed with the material of scaffolding ledger as a steel tube pipe. On this study, it is aimed to guarantee the safety by analyzing the ledger of scaffolding practically and prevent the accident of manager and laborer through the actualization.

  • There are many accident causes related to even an accident. As well four(4) stepped causes of one accident at construction sites are analyzed in the study. First, eleven(11) cause factors are set up at each step such as policy level, management, indirect, direct level which are discussed and determined by field experts with 15year experience or more. Therefore, one direct cause occurred in construction site can be connected to the previous cause than in direct and management, and policy problem of previous management. These questionnaires results are analyzed with three different methods such as weighing level by Delphi technique, correlation analysis, critical pass method. Three different methods show their characteristic to see which subcontract work is more dangerous or not. Subcontract or at a construction site can be use the above three different cases as they need at their site in order to make more effective countermeasures.

  • 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.

  • Accident prevention plan it a construction site should be analyzed and made with risk evaluation and management, from recent year, in Korea. Accidents occurred in construction site are related to all parties such as owner, main and subcontractor, labour. But analyzing some relationship between main and subcontractor is very important to estimate what risk between then are existed in a site. There are some different aspects concerning with risk management between them. Everywork has its own risk in there, This is the reason why everywork which are made by subcontractor himself should be evaluated for risk level. And main contractor should provide for subcontractor to prevent each risk at the work, all the time.

  • The main purpose of this study was to examine relative effects on safety behaviors between global feedback and specific feedback at a construction site. Participants were 30 full-time workers at a construction site. Five safety related behaviors were identified as critical behaviors. An ABCB within-group design was adopted. After baseline (A), participants received global feedback on their average percentage of all five target safety behaviors (B). In the next phase, participants received specific feedback on the percentages of individual target behaviors (C). In the final phase, the global feedback condition was reintroduced (B). Results showed that both global feedback and specific feedback were effective in increasing the frequencies of safety behaviors and there were no differences in the effectiveness between the two types of feedbacks.

  • Techniques based on computer vision are becoming increasingly important in construction safety monitoring. Using AI algorithms can automatically identify conceivable hazards and give feedback to stakeholders. However, the construction site remains various potential hazard situations during the project. Due to the site complexity, many visual devices simultaneously participate in the monitoring process. Therefore, it challenges developing and operating corresponding AI detection algorithms. Safety information resulting from computer vision needs to organize before delivering it to safety managers. This study proposes a framework for computer vision-aided construction safety monitoring using collaborative 4D BIM information to address this issue, called CSM4D. The suggested framework consists of two-module: (1) collaborative BIM information extraction module (CBIE) extracts the spatial-temporal information and potential hazard scenario of a specific activity; through that, Computer Vision-aid Safety Monitoring Module (CVSM) can apply accurate algorithms at the right workplace during the project. The proposed framework is expected to aid safety monitoring using computer vision and 4D BIM.
