It has been announced that Kitaoka Gumi Co., Ltd. (Headquarters: Mima City, Tokushima Prefecture; Representative Director: Masafumi Kitaoka; hereinafter "Kitaoka Gumi") has implemented "GENBAx Tenken" (GENBAx Inspection), a service for paperless inspection forms at construction sites developed and provided by SORABITO Inc. (Headquarters: Chuo-ku, Tokyo; Representative Director and President: Kazuaki Hakata; hereinafter "SORABITO").
Tackling Youth Development and Productivity Improvement through DX
Based in Tokushima Prefecture, Kitaoka Gumi promotes DX in both hardware and software under the vision of making "the construction industry a creative and admired profession."
On the technical side, the company has standardized the acquisition of 3D point cloud data using drone surveying and in-house creation of 3D design data (BIM/CIM). By combining these with GNSS-linked ICT construction machinery, they achieve both millimeter-level precise construction and improved site safety.
Furthermore, in 2025, their new headquarters won first place in its category at a global architecture award (Dezeen Awards). Positioning this as their "DX Base," they have realized administrative efficiency through remote site presence and cloud management. Fusing state-of-the-art workplaces with high-tech construction, they are simultaneously achieving an increase in young recruits and enhanced productivity.
Background of Implementing "GENBAx Tenken"
Against the backdrop of a worsening labor shortage in the construction industry, achieving "labor-saving and manpower reduction" in site operations is an urgent issue. The decision to introduce this service was made specifically to resolve the following three points:
Breaking away from analog management and securing real-time capabilities
With conventional paper-based inspection forms, not only were the documents physically bulky, but there was also the issue of not being able to grasp the implementation status of partner companies in a timely manner. Through going paperless, the goal is to achieve immediate confirmation and centralized management of inspection statuses, even remotely.
Improving evaluations from clients (government offices) and strengthening order-receiving capabilities
As clients, including the Ministry of Land, Infrastructure, Transport and Tourism, strongly promote DX (Digital Transformation), the utilization of ICT is becoming increasingly important as a point-addition item in order evaluations. It is necessary to enhance competitiveness as a company by engaging in DX not only on large-scale projects but also at small-scale sites.
Streamlining dense site operations and pursuing "ease of use"
As it becomes increasingly common for one person to oversee multiple sites concurrently, conventional, complicated form management had become a significant burden. The intuitive and simple operability of "GENBAx Tenken" lowers the barrier to entry for partner companies on site, and it was judged to be the optimal tool for transforming daily inspection tasks from a "burden" into a "habit."
Kitaoka Gumi plans to expand the scope of utilization from the site level to the corporate level, promoting the paperless conversion of all forms beyond just inspection sheets. While reflecting the voices of those on-site, they aim for further improvements in operational efficiency.
SORABITO will continue to develop functions and provide technology to respond to industry-wide challenges such as labor shortages and operational labor-saving, while supporting improvements in safety and productivity at construction sites.

What is "GENBAx Tenken"?
"GENBAx Tenken" is a service that makes all inspection forms used at construction sites paperless, streamlining the management of safety inspections. By digitally managing daily inspection tasks on-site—such as pre-operation checks of construction machinery, equipment, scaffolding, and worker health checks—it eliminates the need to collect paper inspection forms and reduces the hassle of approvals. Furthermore, by managing and sharing inspection results in real-time, it achieves heightened safety management and operational efficiency.
