"Point Weather Forecast" KIYOMASA PRO has obtained "VE Evaluation"!
The weather risk management mobile "KIYOMASA PRO" has received the highest rank VE evaluation (proven effective technology) in NETIS (New Technology Information System of the Ministry of Land, Infrastructure, Transport and Tourism). NETIS Number: KT-230016-VE Technology Name: Weather Risk Management Mobile "KIYOMASA PRO" ◆ Benefits of VE Evaluation 1. Additional points for technical proposals and creativity in construction performance evaluation It is expected that evaluation points will improve during technical proposal submissions for bidding and at the completion of construction (construction performance evaluation). This increases competitiveness compared to using other weather information services, and further recognition from clients and contractors is anticipated. 2. Simplification of procedures Typically, the creation and submission of the "Effectiveness Survey Form," which is required within 30 days after construction completion, will not be necessary, simplifying post-construction procedures. 3. Long-term availability The VE evaluation obtained this time is scheduled to be published for 10 years starting from the year following the initial registration (2024). It can be used over a long period, providing peace of mind. Above all, it is recognized as a superior technology compared to conventional methods, offering tremendous effectiveness as a weather risk management tool to protect sites and workers from localized heavy rain, lightning, and gusts.
GPMate-ECHO is a high-performance GNSS depth measurement system that combines ease of use in the field with high precision.
