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
