Due to the proximity of the sea and the lack of obstructions, we utilized 【ZEROSAI】 to implement strong wind countermeasures during crane operations. 【Operational Environment】 At this site, which is located along the coast, strong winds occur frequently, exceeding 10 m/s two to three times a day. There is a rule that crane operations must be absolutely stopped when wind speeds exceed 10 m/s. We installed the 【N Sensor】 near the site office to manage rainfall and wind speed, which contributed to safety measures and project management. 【Purpose of Implementation】 〇 To make decisions on stopping crane operations by monitoring real-time wind speeds, and to make project decisions based on weather forecasts. 〇 When performing concrete pouring or painting work, operations cannot proceed if it rains, so we need to know timely weather information through predictions and observations to manage the project and determine the feasibility of work.

I will introduce the "Mechanism of Localized Heavy Rainfall." When a large amount of warm, moist air flows into the lower atmosphere and cold air flows in from above, the atmospheric conditions become very unstable, leading to the development of cumulonimbus clouds. As cumulonimbus clouds form successively in the same location and move eastward, they create a linear precipitation zone, causing heavy rain to persist in the same area. The related catalog provides a more detailed explanation of why localized heavy rainfall occurs, including examples from the heavy rain in northern Kyushu. Please take a look.

In the river channel regeneration project, we have introduced the 【Natural Disaster Prevention System ZEROSAI】 with NETIS registration number QS-150021-VE to monitor river water levels and rainfall, and to ensure thorough awareness of dangers. Equipment Configuration: 【N Sensor】【Battery-operated Water Level Gauge】【Disaster Prevention Light】 Even during work, the disaster prevention light installed on-site continuously disseminates weather information and water level data to the workers. This allowed for compliance with the on-site code of conduct. Additionally, the water level gauge previously used was prone to breaking during freezing conditions, but with ZEROSAI, there is no such concern, and it can be easily removed and reinstalled, which also serves as a safety measure for the surrounding area. ■ Objectives - Understanding river water levels and rainfall, and ensuring thorough awareness of dangers - Establishing behavior standards and building a rapid evacuation system - Conducting evacuation drills assuming rapid water level rises ■ Effects - Workers can grasp the situation and comply with the on-site code of conduct even while working - During water level rises, dangers can be communicated, ensuring rapid evacuation actions by workers - There is no concern about breakage during freezing conditions, and relocation and installation can be easily performed, enhancing safety measures for the surrounding area *For more details, please refer to the PDF document or feel free to contact us.

In construction work for a private company, we introduced ZEROSAI for the purpose of email notifications to halt crane operations when the wind speed observed on-site exceeds the threshold for stopping work, as well as alarms directed at workers through a disaster prevention light. All employees can view weather information from their smartphones and PCs, and we have set up notifications to be sent in conjunction with email alerts through business chat platforms like LINEWORKS and direct. This allowed us to determine in advance the timing for folding the crane's boom. We received feedback from our clients that the wind predictions are highly accurate, hitting the mark right on time, making it extremely useful at our site, which is exposed to strong winds without any obstructions. **Case Study** - **Objective** - Thorough notification of crane work stoppage via email, business chat, and disaster prevention lights. - Continuous monitoring of 24-hour wind forecasts on office monitors and thorough preemptive crisis avoidance actions. - **Effect** - All employees were able to execute work plans with a shared understanding. - We were able to determine in advance the timing for folding the crane's boom. *For more details, please refer to the PDF document or feel free to contact us.*

We will introduce the implementation results of the natural disaster prevention system "ZEROSAI." In Oita Prefecture, for mountain conservation work, we introduced the "ZEROSAI" disaster prevention panel, N sensors, disaster prevention lights, cameras, and power boxes to obtain pinpoint weather forecasts for pre-judgment of work feasibility based on rainfall, strong winds, and temperature. As a result of the implementation, the objectives were achieved. Additionally, by utilizing "ZEROSAI," we were able to take measures such as pre-judgment of work feasibility, pre-evacuation during abnormal weather, quality control of mortar during low temperatures, and conducting phone meetings with the client via live cameras. 【Case Study】 ■ Objectives - Obtain pinpoint weather forecasts - Pre-evacuation during abnormal weather (rainfall, strong winds) - Client can grasp the site situation in real-time (camera) ■ Effects - The above implementation objectives were achieved - Pre-judgment of work feasibility - Pre-evacuation during abnormal weather - Quality control of mortar during low temperatures - Phone meetings with the client via live cameras *For more details, please refer to the PDF document or feel free to contact us.
