Thank you for always watching. This time, I will talk about important indicators used in port operations. Depending on the site environment, offshore construction is easily affected by waves and wind, and it is particularly necessary to carefully consider weather conditions in cost management and labor management. For this reason, there is an important keyword in offshore construction known as "utilization coefficient." This time, we will take a rough look at this "utilization coefficient." 1. What does "utilization" mean? 2. Calculation of the utilization coefficient 3. Concept of the utilization coefficient 1. What does "utilization" mean? First, "utilization" refers to the state in which machinery and equipment have been delivered to the construction site. The number of days from when the equipment is delivered to when it is removed is called "utilization days." Additionally, the construction period (excluding preparation and cleanup) includes not only the days when work is performed (operating days) but also non-operating days (holidays, safety training days, days of inclement weather, etc.). The remaining days in a year (365 days) after excluding these non-operating days constitute the annual "operating days" for the machinery and equipment. *For more details, please visit our website or feel free to contact us.

In recent years, extreme weather phenomena such as localized heavy rains caused by linear precipitation zones, unpredictable gusts of wind, and record-breaking heatwaves have been increasing. To ensure safety on-site, there is a demand for more accurate weather forecasts and swift decision-making. There are three main reasons why weather risk management is difficult at construction sites and factories: 1. Information is dispersed. Weather forecasts, wind speeds, heatstroke indices, rainfall... necessary information is spread across multiple systems and apps, making comprehensive decision-making time-consuming. 2. Information sharing is challenging. Only a few people are aware of the weather information, and it does not reach cooperating companies or on-site workers, making it difficult for everyone to have the same understanding in emergencies. 3. Localized forecasting is difficult. General weather forecasts target broad areas, and there are limitations to precise predictions at specific construction sites. This is especially true in mountainous or coastal areas. For future weather measures, "centralized management" and "visualization" will be key. Sysmet Corporation released the comprehensive weather platform ZEROSAI X-AI on February 18, 2026, to address these challenges. For more details, please visit our website or download the PDF.

Thank you for your continued support. On February 18, 2026, we will release the comprehensive weather platform ZEROSAI X-AI.

In light of the recent increase in heatstroke-related fatalities due to extreme heat, the Labor Safety and Health Regulations will be revised starting June 1, 2025, making heatstroke prevention measures mandatory in the workplace. This is particularly important in the construction industry, where outdoor work is common, and it is expected that each worker is mindful of heatstroke prevention on a daily basis. However, to safely navigate summer work, it is essential to implement heatstroke prevention measures not only at the individual level but also as a systematic approach. Sysmet Co., Ltd. has created a "Heatstroke Prevention Handbook" as a private meteorological company. This handbook is divided into two parts: "Basic Knowledge" and "Prevention Measures." The latter part, which focuses on prevention measures, introduces examples of heatstroke prevention strategies that can be realized through the "Natural Disaster Prevention System ZEROSAI," which allows for centralized management of weather information observation, forecasting, and notification. Please feel free to utilize this handbook as training material or for safety meetings, tailored to the safety measures of each site. *For more details, please visit our website or feel free to contact us.*

We will introduce examples of the implementation of the Natural Disaster Prevention System ZEROSAI (Registration Number QS-150021-VE) in civil engineering and construction work in the construction industry. It can be utilized not only for safety measures but also for creative ideas and technical proposals. [Before Implementation] Due to the proximity of the sea and the lack of obstructions, there were many sudden gusts of wind, making it difficult to determine whether it was safe to continue work. <Issues> - Checking weather apps for work decisions took time, and there was a time lag in informing the entire site. - Delays in deciding to halt work due to strong winds led to cases where work continued while risks were present. We introduced our Natural Disaster Prevention System ZEROSAI along with the optional three-color signal light. For more details, please visit our website or download the PDF.

In recent years, there have been increasing opportunities to feel summer-like heat starting around May. This raises concerns about heatstroke. Particularly in the construction industry, where outdoor work is common, each worker is likely to be mindful of heatstroke prevention on a daily basis. However, to safely navigate summer work, it is important not only to have individual measures but also to implement systematic heatstroke prevention strategies. Sysmet Co., Ltd. has created the "Heatstroke Prevention Handbook: Basic Knowledge Edition" as a private weather company. This book is structured in two parts: "Basic Knowledge Edition" and "Utilization Edition." The Basic Knowledge Edition clearly conveys the current state of heatstroke and the knowledge necessary for creating effective systems. Please feel free to use it as training material or safety conference resources for safety measures specific to each site. *For more details, please visit our website or feel free to contact us.*

[Before Implementation] We want to share information about heatstroke on-site and improve safety measures for workers. <Challenges> It is necessary to obtain weather information that is relevant to the site. We need to monitor the Wet Bulb Globe Temperature (WBGT) and share information with all stakeholders in real-time. Using the Weather Forecast Analysis Distribution System [Disaster Prevention Panel], we conducted predictions of the Wet Bulb Globe Temperature (WBGT) and installed weather observation equipment [N Sensor] on-site to monitor the WBGT. Additionally, by linking the Disaster Prevention Panel with business chat, we efficiently shared information with stakeholders.

【Before Introduction】 In the mountainous area of Hakuba Village, Nagano Prefecture, construction work was hindered by a lack of signal, making it difficult to observe rainfall and water levels. <Challenges> Due to the construction in the mountains, there is a risk of rising water levels from sudden heavy rain.
