Nippon Kanzai Launches On-Site DX Service “KANNA”

Aldagram Inc., which is committed to improving productivity in the non-desk work industry, has introduced its on-site digital transformation service “KANNA” to the eastern and western offices of Nippon Kanzai Co., Ltd., a major comprehensive building management company. By utilizing KANNA, the company has significantly reduced the travel time to remote on-site locations, which had previously been a major burden, and has established a system that allows the efficient parallel management of multiple projects while maintaining quality.

 Nippon Kanzai, which operates a comprehensive building management business nationwide, needed to manage projects at multiple locations in parallel with a small number of people at the Engineering Management Headquarters (Construction Management Department). For example, the East Japan location, while based in Tokyo, was responsible for seven to eight sites at the same time in remote locations such as Gunma and Chiba, making physical travel and management a major issue. Before the introduction of the system, information was mainly shared by phone, email, and paper media, and if the person in charge saved the documents on their computer, other employees were unable to follow the progress. In addition, on-site reports from clients were not timely, and the completion status of night-time construction work or when problems occurred at the site could not be grasped until the person in charge visited the site or confirmed it individually by phone, which caused inefficiency.

With these challenges as a backdrop, the company considered ways to improve operational efficiency through digitalization. As a result, KANNA’s desired “photo ledger” and “chat” functions were simply integrated, and its intuitive operability was the deciding factor. In addition, the fee structure that allows unlimited invitations to representatives (from other companies) for free was also suitable for the company’s operations, which work with many business partners, and encouraged the company to introduce it.

With the introduction of KANNA, unnecessary site visits, which previously occurred due to a lack of information making on-site confirmation necessary, have been significantly reduced. Problems that occur at remote sites can now be resolved without going to the site by sharing photos and comments on KANNA, and completion reports for nighttime work can be confirmed the next morning on a smartphone. This has reduced travel time for staff, allowing them to focus on their core management duties.

In addition, by consolidating information in the chat function for each case, communication has become faster because there is no longer a need for a large number of CC’d emails or formal exchanges starting with standard phrases. Past exchanges can be easily traced back in chronological order, making the history of the case clear to everyone, and a system has been established that allows other members to smoothly grasp the situation and respond even when the person in charge is absent.

Furthermore, because photos, drawings, and communication history are all stored linked to the project, even if a problem occurs several years later, KANNA functions as an “asset” that allows the situation at the time to be immediately confirmed without having to search through folders on the server. In the future, the company plans to expand the use of KANNA not only to the construction management department but also to the “building diagnosis” team, which has been using paper for many years, with the aim of improving work efficiency and productivity across the company.
