Starting from January 2026, we are pleased to announce that by linking the measurement data collected on the "Fieldroid Cloud" with the BIM/CIM cloud "KOLC+" provided by Cork Inc., it has become possible to centrally display measurement data summaries on the digital twin. (Examples) Measurement of various environmental data using Cloud Logger LTE Forecasting wind speed, rainfall, and heat index using Signroid 2 Temperature and humidity measurement during concrete curing using Ondroid Slope monitoring using Guraloid Displacement measurement using the shape displacement measurement system "G-Gauge" The data measured by the above services is sent to the cloud, enabling graph displays and alert email notifications. With the implementation of the data linkage function, it is now possible to visualize the latest measurement data from the Fieldroid Cloud on the digital twin constructed in "KOLC+". For more details, please check the content on the linked page.

Regarding the "quotation" used at the forefront of sales activities: "Do we need to save everything when we revise it to Ver.1, Ver.2, etc., every time the amount or specifications change?" "Should we also keep the data from other companies that were not selected in competitive quotations?" Have you ever wondered about these questions? The Electronic Bookkeeping Act strictly demands the "authenticity" of data, but saving all processes is a significant burden for the field. This time, we will clearly explain the boundaries of the preservation obligation in a case study format, incorporating interpretations from the latest National Tax Agency Q&A. *You can read the full text from the note in the "Related Links." [Contents of this article] 1. The boundary of the preservation obligation lies in "sending to external parties." Items sent externally are "generally required to be preserved." Items that have not been sent externally have "no preservation obligation." 2. Judgment from the sending side: "Is it linked to a transaction?" 3. Judgment from the receiving side: "The perspective of the 'Corporate Tax Act' is important." ■ Note! "Version revisions" and "corrections/deletions" are different things. ■ A smart way to ensure reliable "version management." ■ Summary.

We plan to exhibit at the Disaster Prevention Industry Exhibition 2026, which will be held at Tokyo Big Sight in the last week of January.
