Recently buildings are constructed in larger and higher scales and becoming more complex. Every country in the world is competing to build high-rise buildings. Korea also has and is constructing high-rise buildings, like the 123story Jamsil Lotte Super Tower. However from small to large scale buildings and on construction sites there still are fire safety accidents that occur continuously. Therefore to improve fire safety plan, examining the actual fire safety management and understanding fire risk analysis Using Fire Modeling through Computer Simulation. Fire safety management plan related fire safety cases were collected an dan analyzed for the study. Also hazard analysis of High rise Buildings under fire compared with existing fire law sand regulations.

This paper summarized the safety diagnosis method in the field of durability among the structural safety suggested in the safety diagnosis manual of the reconstruction project and analyzed the safety diagnosis case. It is expected to be a reference material for safety diagnosis in the field of durability by pointing out cases that are wrong during existing safety diagnosis and cases where diagnostics are likely to make errors.

In the design and maintenance of buildings, identifying the degree of damage in the event of a fire is an important factor in fire prevention and fire safety design. In order to predict fire damage, safety measures should be established by predicting the nature of evacuation according to fire, smoke and in-house characteristics, and the effects of the operation of fire safety facilities should also be considered, but in Korea, the risk analysis due to the operation of fire safety facilities is insufficient. Accordingly, this study uses fire statistics and sprinkler inspection data to analyze the degree of fire damage caused by the operation of sprinkler facilities in a probabilistic manner.

In 2022, construction had a five fold higher accident and fatality rate compared to the overall industry. The Construction Technology Promotion Act requires parties in construction contracts to calculate safety costs following Ministry of Land, Infrastructure and Transport guidelines. Understanding safety expense components is vital for evaluating accident prevention costs and planning anti-accident strategies. A study surveyed safety professionals to analyze the importance and influence of safety management expense components, providing basic data for future research. Survey results highlighted the significance of safety management plans, structural safety assurance, and preventing collateral damage.

Leaking of fuel gas in a building creates flammable atmosphere and gives rise to explosion. Observations from accidents suggest that some explosions are caused by quantity of gas significantly less than the lower explosion limit amount required to fill the whole confined space, which might be attributed to inhomogeneous mixing of the leaked gas. The minimum amount of leaked gas for explosion is highly dependent on the degree of mixing in the building. This paper proposes a method for estimating minimum amount of flammable gas for explosion assuming Gaussian distribution of flammable gas.

A large-scale research project to develop a robot-based automated building construction system for steel structures was successfully conducted in South Korea. This paper discusses the results of the real-scale test and the key lessons gained from the testing process. The system was assessed in terms of system productivity, construction cost, quality control, and safety improvements. While the productivity of the automated system showed an improvement of about 9.5%, the construction cost was about six times higher than that of the conventional method. The field test also indicated that the automated system requires more on-site quality control measures. However, because the system can eliminate the causes of various safety accidents, safety levels might be expected to be improved significantly. It is expected that this paper will provide knowledge and insight for developing new systems, and the results of the real-scale test might be useful for other researchers and similar research projects in the future.

Remodeling is not subject to strict laws or regulations for permission procedure and structure safety inspection compared with new construction. Most of building owners do not recognize the importance of structural safety enough and place an order to small unlicensed construction company. As a result, important structural materials are damaged without enough investigation into permitted durability and fixed weight and load weight increase. This study suggests a system that can evaluate the state of the building and enables fast judgment on needs of repairing or strengthening as well as needs structural examination.

The construction of roads, tunnels, and bridges results in changes to the local terrain that may influence the ground safety factor, which represents the stability of geotechnical structures. In this study, we assessed construction sites that had collapsed as a result of terrain change, and then simulated variation in the ground safety factor with respect to terrain change caused by road construction. We assumed steep slopes to simulate changes in terrain in a mountainous area and assumed that earthworks took place for road construction by cutting a platform into the slope and altering the slope angle of the terrain both above and below the road. We calculated values of the ground safety factor through a stability analysis of the slope both above and below the road, and examined the variation in the safety factor of the above- and below-road slopes with respect to changes in road width. We found that if the slope angle was the same above and below the road, then the change in the ground safety factor during/after road construction occurred in the slope below the road, and if the slope angle above the road differed from that below, then the change occurred in both the above- and below-road slopes. Furthermore, the ground safety factor was essentially constant for road widths exceeding 2-6 m, depending on both above- and below-road slope angle. The findings of this study can be used to guide the management of construction sites and to assess changes in ground stability during road construction work, particularly in the early stages of earthworks, when the road width is narrow.

Safety management is the most important factor in the construction industry. If the construction company don't control the risk, it causes the accident which give the company fatal loss. According to the Korea industrial safety analysis reports, the 25.72% of the disasters are from the construction industry, and the 13.6% construction disasters are caused by not properly using the safety gears. Therefore, this study is to investigate the Wearing Safety Gear by Occupational Classification and the Satisfaction in the Construction Field. The results are ; Carpenters are dissatisfied with the safety shoes and belt, re-bar workers are dissatisfied with the safety helmet and shoes, Concrete workers are dissatisfied with the safety helmet and goggles.

A major purpose of management or occupational safety is a significant decrease in safety accidents. With this view, the establishment of occupational safety culture and the building of occupational communication network stand out as being more important than the past. This study has analysed the positive effects of occupational safety communication on safety consciousness and action of the employees in workplace. And it is confirmed that the occupational safety communication in workplace is the essential mechanism, through which the workers internalize safety consciousness and act safely. The safety consciousness and action of the employees are formed in safety culture, which is not only legal regulations, but a daily communication network in workplace. In these sense, the building of the occupational safety communication network is decisive for the establishment of safety culture. For these reasons, this study makes the proposition that a firm promotion of occupational communication network is necessary, which connects the safety culture and a effective safety management in workplace.
