While efforts to reduce safety accidents in the construction industry have been made in a variety of ways, so far they have had minimal effectiveness. For this reason, since 2016 Design for Safety (DfS) has been implemented as an attempt to eliminate the root cause of safety accidents by introducing the consideration of safety at the design stage. The purpose of this study was to derive the adequacy and problems of Design for Safety and to contribute to reducing safety accidents by establishing this system correctly. A questionnaire survey of related engineers and analysis of the Design for Safety report showed that the awareness of Design for Safety among engineers was low, while some of the risk factors derived from the design for safety were less relevant to the design. As such, efforts should be made to reduce the risk factors in the actual design stage so that it can contribute more to the reduction of safety accidents.

A conventional Design for Safety (DfS), introduced to eliminate potential hazards in the design phase proactively, has encountered persistent challenges, such as perfunctory risk assessments and hazard identifications based on 2D drawings and inefficient workflow processes. This study proposes a BIM-based approach to Design for Safety (DfS) to address the limitations of conventional methods, aiming to enhance efficiency and achieve practical safety management benefits. The proposed workflow process for BIM-based DfS has been refined and validated for on-site applicability through various case studies, including risk assessments during the design phase and field applications for safety management activities during the construction phase. Specifically, the critical process of risk assessment within the DfS methodology has also been transitioned to a BIM-based approach. This BIM-based risk assessment process has been evaluated through case studies, encompassing safety reviews for structural design, construction equipment operation, and construction methodology with sequence in design projects. Additionally, the proposed BIM-based DfS has demonstrated exceptional on-site applicability and efficiency, as validated by the application of a BIM deliverable embedded in DfS information for CDE-based daily activity briefing, VR-based safety training, AR-based mitigation measures inspections, and other safety management activities in the construction phase.

This study introduces the current status of the design for safety(DfS) introduced as one of the owner - centered construction site safety management plan, and presents the problems and the improvement plan. The design for safety has been shifting from the construction management-oriented safety management to the owner-centered safety management system, The owner has to make the design considering the safety from the design stage centered on the owner. The owner has to review and approve the adequacy of the safety-conscious design and The risk factors that can not be eliminated during design are the system to prevent the disaster at the construction site by planning to eliminate the risk factor when writing the safety management plan that is made at the construction stage. The design for safety system implemented from May 2016 will be further developed to prevent the risk of safety accidents that may occur in construction sites, contributing greatly to the reduction of construction accident. In addition, it suggests ways to develop more efficient and convenient system through continuous hazard finding and system improvement.

Purpose: The purpose of this study is to prevent construction safety accidents, and the design safety systems were reviewed. This paper aims to establish as an effective system by looking at the implementation procedures and contents of the design safety review system. Method: We reviewed the purpose and content of the law, accident statistics, etc. for the study. In addition, we looked at the implementation plans for actual construction sites using the 'design safety' assessment process as defined by the Act. Results: We divided it into the data review phase, the risk factor elicitation and alternative setup phase, and the design safety assessment report preparation stage. Conclusion: it is necessary to derive risk factors that take into account the diversity of construction sites. However, the effectiveness of other reports is questioned as they are often copied and written. Therefore, it is necessary to strengthen external verification procedures attended by construction safety experts.

Recently, due to the rapid growth of the leisure industry, demand for small-scale flotation and mooring pontoon platforms has been increasing rapidly. Standard rules for the design and structural safety of such structures have become necessary. This paper provides criteria that can be referenced when designing pontoon platforms, and also introduces structural safety evaluation procedures. In this study, the structural safety and stability of a 15-meter pontoon platform were investigated through structural design and finite element analysis. For platforms of less than 10 meters in length, a simple structural calculation can be used, but for platforms over 10 meters, a detailed structural strength review must be considered to meet safety guidelines defined in existing regulations. The structural strength of the initial design was examined and its structural safety was verified. For future research, it is an evaluative system was developed that can be used to examine the various loading conditions during design.

Design for Safety(DfS) at the design stage is introduced and executed in order to fundamentally reduce the occurrence of construction safety accidents in Korea. Therefore, in this study, the construction method selected by Design for Safety can reduce safety accidents, but the effects on construction duration and costs were examined to confirm the effectiveness of various aspects. The construction method of the structural frame for the exterior wall cladding of the building, which have the factors for the fall accident, was selected for construction safety and compared and analyzed in terms of construction duration and costs. As a result, it was found to be effective not only in terms of safety, but also in terms of construction duration and costs. Therefore, it is considered that the construction method selected by the Design for Safety at the design stage will have a positive effect on the entire construction project.

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.
