Aldagram Inc. (Headquarters: Chuo-ku, Tokyo, Representative Director: Hikaru Nagahama, hereinafter Aldagram) announces that its field DX service "KANNA" has been implemented in the building maintenance operations of Machida City, Tokyo (Mayor: Yasuharu Inagaki, hereinafter Machida City) starting March 1st.
[Background and Challenges]
Currently, the entire construction industry faces a chronic labor shortage due to an aging workforce and a declining working population, making productivity improvement through work style reforms an urgent issue. The Building Maintenance Division of the Finance Department in Machida City was also required to promote efficient building maintenance operations within limited resources to maintain the safe and comfortable use of city-owned buildings.
In traditional building maintenance operations, many of the vast document procedures based on laws and standards are handled on paper, which meant that contractors (construction companies, etc.) generally had to print and bind documents, as well as submit them in person at the city hall counter. Such analog administrative procedures have become a significant physical and time cost burden for both the orderer and the contractor.
Furthermore, because communication with the site was limited to phone calls and emails, there were risks of time lags in information transmission and omitted communications. Additionally, since progress status and document management for each project were handled by individual persons in charge, achieving "visualization" across the entire organization was a challenge.
Under these circumstances, the city aimed to promote DX by utilizing a construction management app as an initiative to improve productivity for both orderers and contractors.
[Reasons for Adoption]
The biggest reason "KANNA" was adopted by Machida City lies in its centralized management system, where the progress of numerous construction projects, photos, drawings, and chat communications can be completed on a single screen. This eliminates information transmission losses between city staff and construction contractors, realizing improved productivity in building maintenance operations.
Additionally, the ability to issue unlimited external partner accounts was extremely highly evaluated, as it allows for stable operation without the worry of additional costs due to an increase in projects during the fiscal year.
Furthermore, compliance with the strict information security policies essential for a local government was a crucial key in the final selection.
[Implementation Overview]
Implementation Start Date: March 1, 2026
Implementing Department: Building Maintenance Division, Finance Department, Machida City
Main Features: Centralized project management, real-time chat, photo/document data management, progress visualization

The field DX service "KANNA" develops two services: "KANNA Project," a project management app supporting front-lines worldwide, and "KANNA Report," a digital form app promoting paperless operations.
