【Operating Environment】 N sensors are installed on-site to observe rain, wind, temperature, and humidity in real-time. Additionally, since there is no power supply on-site, operations are conducted using solar power equipment. 【Purpose of Introduction】 - Since work is being carried out within scaffolding, it is necessary to manage the temperature and humidity inside the scaffolding rather than the outside air temperature. Therefore, only a hygrometer is installed inside the scaffolding to manage the quality of the concrete. - Rapid information sharing with workers is facilitated through email notifications. - Observation data is utilized as supporting documentation. 【Operating Method】 - A hygrometer with built-in communication functionality is installed in the designated slab area to collect real-time observation data, thereby managing the quality of the concrete within the scaffolding. - Project management is conducted by utilizing forecast data from long-term, short-term, and ultra-short-term perspectives. - In the event of exceeding the standard values of weather forecasts or N sensor observation values, email notifications are sent to workers to alert them, enabling prompt action and preemptive measures. - Observation data can be output as PDF files for daily and monthly reports, which can be directly used as supporting documentation.

【Operating Environment】 Install 【N Sensor】 and 【Web Camera】 at the top of the embankment on-site, centrally managing weather information and camera footage in the cloud. Since there is no power supply on-site, it operates using a solar power storage system. A fixed-point camera is installed in front of the site office for security measures. 【Purpose of Implementation】 〇 There is a distance between the site office and the site, requiring personnel to move to check the situation. Therefore, 【ZEROSAI】 is implemented to view real-time weather conditions and make judgments without going to the site. 〇 By having site workers view the 【Disaster Prevention Board】, they can share the same information and act with a unified awareness. 〇 Using the 【Web Camera】, the situation can be understood even when not present on-site, alongside weather information. 【Operational Method】 〇 Since there is no limit on the number of people for the 【Disaster Prevention Board】, information is shared with partner companies while managing the process based on real-time weather information. 〇 During construction interruptions, data for the day can be extracted on a daily report basis, which can be used as justification for the client. 〇 During embankment construction, caution is needed regarding the inflow of earth and sand, so both short-term and long-term forecasts are monitored for proper management.

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.

【Operating Environment】 Install the [N Sensor] on-site to observe rain, wind, temperature, and humidity in real-time. Additionally, since there is no power supply on-site, operations will be conducted using a solar power system. 【Purpose of Introduction】 〇 In the event of a sudden heavy rain during construction, it is difficult to respond quickly on-site, so it is necessary to avoid dangers to workers from landslides and mudflows in advance, which is why it is introduced for weather forecasting and project management. 〇 The mudflows caused by sudden heavy rain can also negatively affect the quality of the cut-and-fill soil, so it is introduced to ensure quality. 〇 It is essential to implement measures to predict and respond to localized heavy rain in advance.

In the coastal beach nourishment project commissioned by the Hokuriku Regional Development Bureau, the site faces the Sea of Japan and has a high shared coefficient (coefficient 5), allowing the observation data to be utilized as evidence. Since it enables centralized management of oceanographic forecasts and meteorological observation values, the person in charge of comprehensive evaluation decided to adopt it for technical proposals, leading to the successful bid. In addition to oceanographic forecasts (wave height, period, swell), we have installed meteorological observation devices (rainfall, wind, temperature), a web camera for remote monitoring of the site, and an alarm transmission device to communicate information to the construction site. The greatest advantage is that all of these can be centrally managed with Compass PLUS.

We would like to introduce the implementation results of the small wave height observation device "Digi-Jellyfish." It has been installed at locations strongly affected by seasonal winds and where there is a discrepancy between the wave heights reported by Nowcast and the actual site. The utilization factor did not match the actual situation, resulting in many days when work could not be carried out due to bad weather. Therefore, we introduced "Digi-Jellyfish" to submit the data observed with it as evidence to the construction client. With the introduction of Digi-Jellyfish, we were able to present evidence of the discrepancy between the local wave heights and those reported by Nowcast to the client.

We will introduce the implementation results of the natural disaster prevention system "ZEROSAI." Since the introduction began in July, measures against heatstroke were necessary. The client has also been strictly instructing on accidents related to heatstroke, so "ZEROSAI" was implemented as a preventive measure. Originally, this site had a rule to take breaks three times in the morning and three times in the afternoon for heatstroke prevention. In addition, when the values measured by the weather observation device "N Sensor" installed on-site reach the standard value, a notification is sent via email and the warning transmission device "Disaster Prevention Light" (electronic display board), at which point all on-site work is halted for a break and hydration. [Case Study] ■ Purpose - With the introduction starting in July, heatstroke is a major concern for several months. - Preventive measures against heatstroke are necessary. ■ Measures - Continuous monitoring of on-site observations. - Email notifications when temperature or WBGT (Wet Bulb Globe Temperature) exceeds the standard value. - Simultaneous alerts to workers via the disaster prevention light. ■ Effect - When a notification is received, all on-site work is halted for a break and hydration. *For more details, please refer to the PDF document or feel free to contact us.
