Activities related to the dissemination of road slope disaster prevention technologies and methods in the Kingdom of Bhutan.
Our company implemented the "Dissemination, Demonstration, and Business Development Project for Road Slope Disaster Countermeasures Technology and Methods in Bhutan" under the Japan International Cooperation Agency (JICA) from August 2019 to June 2023. The Kingdom of Bhutan has about 70% of its land in mountainous areas, exposing it to risks of falling rocks and landslides, with slope disasters frequently occurring on its main infrastructure, the roads. This not only causes human casualties and creates isolated areas, but also significantly impacts local industries due to road disruptions. Furthermore, the lack of specialized engineers for rockfall and landslide countermeasures in the country, as well as the absence of companies capable of designing and constructing countermeasure facilities, poses a major challenge. In response, our company has worked on local demonstrations of products to stabilize road traffic and support steady economic development. Specifically, we installed two products, "Geo-Lock Wall" and "Macro Net," on-site. These efforts contribute to reducing human casualties from slope disasters, improving logistics efficiency, and fostering regional economic growth through industrial development. Moving forward, we will continue our activities to promote slope disaster countermeasure technologies and methods on roads in Bhutan and surrounding South Asian countries, contributing to economic development.

We will hold a webinar introducing the NETIS registered technology Hatsuly!
■Event Overview In infrastructure construction sites, the need to extend the lifespan of existing structures through repair and maintenance is becoming increasingly important, in addition to the new construction of roads and bridges. Currently, the process involves identifying specific damaged areas that require repair, measuring the area, and manually calculating the amount of mortar needed for restoration after measuring the depth at multiple points using a water line. Our company has developed "Hatsuly" as an approach to address the above challenges, based on feedback from users and various infrastructure managers during our provision of the labor-saving product "Modely" for rebar inspection. Due to a recent surge in inquiries and the completion of NETIS registration, we have decided to hold a webinar to introduce the basic functions of Hatsuly. We will also showcase actual demo screens for clear understanding. ■Program Content Explanation of Hatsuly Overview Demonstration using Hatsuly demo screens Q&A ■Recommended for Those involved in construction such as cross-section repairs who want to achieve labor savings Those looking to gather the latest information for technical proposals Those interested in the latest 3D data utilization tools
