A case study of Goyo Construction Co., Ltd. that achieved smooth information sharing among stakeholders.

Goyo Construction Co., Ltd. (hereinafter referred to as Goyo Construction), which is working to improve productivity at construction sites for civil engineering, architecture, and offshore wind power, has conducted a demonstration experiment to visualize the location information and operational status of heavy machinery in real-time in order to reduce the effort and time required for the placement and management of heavy machinery used in daily construction planning. By reflecting the location information of heavy machinery obtained from SoftBank's high-precision positioning service "ichimill" onto Goyo Construction's integrated construction management system "PiCOMS," the work required for information sharing among stakeholders has been automated, significantly reducing the burden on the site.

basic information

RTK technology enables positioning with an accuracy of a few centimeters, with over 3,300 unique reference points established nationwide. Ichimill utilizes signals received from GNSS, such as the quasi-zenith satellite "Michibiki," to perform RTK positioning, allowing for centimeter-level accuracy in positioning. *1 GNSS (Global Navigation Satellite System) refers to a collective term for satellite positioning systems such as QZSS (Quasi-Zenith Satellite System), GPS, GLONASS, and Galileo. *2 RTK (Real Time Kinematic) positioning is a method that uses two receivers, a fixed station and a mobile station, to exchange information in real-time between the two points, enabling high-precision positioning.
