The key factor is the clarity of being "specialized in conversation," which can also be used by craftsmen!

Time reduction and efficiency! Active utilization of contractors enables quality traceability management and visualization of the site! "Collection of key points for operational success - now available!"

We would like to introduce a case study on the implementation at Rino Stage Co., Ltd. Before the implementation, there were concerns about how to accommodate users still using feature phones. Therefore, in the preliminary announcement, we first communicated the benefits of using "Kizuku" in business, explaining that a smartphone would be necessary for that purpose. As a result, while not at 100%, the transition to new devices progressed quite closely, and we were able to achieve a good level of penetration. As for the effects and improvements after implementation, in terms of library sharing, the supervisor used to travel back and forth between the site and the office every time there were changes or questions, but this necessity has been eliminated, allowing for time savings. *For more details, please refer to the related links or feel free to contact us.*

The most important aspect of construction management at the design office is "traceability management" [Kizuku case study].

The most important aspect of construction management at the design office is "traceability management" [Kizuku case study].

Real-time and quick response! Utilizing the "Important Talk" feature makes all interactions evidence of construction management. "Collection of Key Points for Successful Operation - Now Available."

Carlo Post Co., Ltd. is a design office that conducts inspections and surveys of new and used houses, as well as designing, managing, and constructing new homes and renovation projects. With about three staff members, they handle approximately 130 seismic reinforcement projects daily. Previously, they experienced a constant influx of phone calls for business communications, leading to a "non-stop ringing" situation. Sudden changes in floor plans and reinforcement proposals often resulted in delays in creating drawings, which was a challenge. With the introduction of "Kizuku," they can now keep photos of all the construction sites. Additionally, areas that previously took a long time to address can now be handled in real-time and in a short amount of time while viewing the drawings on a tablet. [Case Overview] ■ Reason for Introduction and Deciding Factor - They wanted a photo management app with a chat feature. ■ Innovations in Implementation and Operation - They proposed switching to smartphones, considering it a zero-start. ■ Effects and Improvements After Implementation - The "Important Talk" feature, which retains history, serves as a good luck charm. *For more details, please refer to the PDF document or feel free to contact us.
