Abstract
The increasing occurrence of abnormal weather conditions such as unusually heavy rains and strong winds adversely affects construction work. However, although these phenomena are localized, conventional weather forecasts have insufficient spatial resolution and update frequency to accurately predict weather conditions at construction sites. To address this issue, we introduced a pinpoint weather forecasting technology that improves spatial resolution and update frequency. The weather information obtained from this technology is processed and provided to construction sites in a comprehensible state, which enables construction workers to better prepare for weather conditions, thereby reducing the risk of accidents and delays. Furthermore, a safety management system was developed based on the relationship between weather and labor accidents. Predicting workplace accidents that are likely to occur on that day based on the impact of weather on the body enabled performing safety awareness activities, such as morning and lunch meetings, from a new perspective, improving safety awareness among construction workers and reducing the number of accidents on construction sites. This paper describes the development process of the proposed system and the utilization of weather forecasting at construction sites, which can be applied to other industries and contribute to improving safety and efficiency in various fields.
