Unlike tape, it leaves no adhesive residue and allows for easy maintenance. - It is constructed with strong magnets, making it difficult to move even when large vehicles pass over it. *Prolonged neglect may cause curling and rust on the metal plate, so regular maintenance is recommended. Please avoid operating the handle on the mat, as it may cause curling, tearing, or entanglement. *For more details, please download the PDF document below.

◆Added to the points for construction performance evaluation Safie Co., Ltd.'s outdoor cloud recording cameras "Safie GO 360" and "Safie GO PTZ AI" were registered in the Ministry of Land, Infrastructure, Transport and Tourism's new technology information provision system "NETIS" on May 20. As a result, the use of both cameras in public works will be eligible for additional points in construction performance evaluations. ◆Improving efficiency and safety on site The "Safie GO 360" is easy to install and can capture a panoramic view of the entire site, clearly displaying objects even at close focal distances in narrow areas. The "Safie GO PTZ AI" allows for adjustments to the shooting range according to the schedule, even on large sites, and enables pinpoint verification of objects several tens of meters away. Additionally, with edge AI features for person detection and counting, it can detect unauthorized access and count the number of people passing through. In construction sites, person detection and notification help prevent material theft and enhance safety management, while quantitatively understanding the flow of people in target areas aids in event planning. These two models reduce movement and working time on site, enabling remote progress management and safety checks. They also comply with regulations on overtime limits, achieving overall efficiency and productivity improvements across the industry.

◆Achieving Reduction of Labor Burden on Site through BIM Utilization Mitani Sangyo Co., Ltd. announced on May 16 that it has received a subsidy for the Takano Home Ishikawa Branch New Construction Project, a joint venture with Takano Construction Co., Ltd., as part of the Ministry of Land, Infrastructure, Transport and Tourism's Building BIM Acceleration Project for fiscal years 2022-2023. The company states that by utilizing BIM in this project, it has realized a common understanding between the client and contractor from the design stage and minimized rework during construction, thereby reducing the labor burden on site. ◆BIM Contributes to Solving Challenges in the Construction Industry, Promoting Adoption through Subsidies BIM visualizes building information to facilitate confirmation processes among stakeholders, addressing various challenges in the construction industry, such as improving efficiency in design and construction and enhancing quality. To address the issue of long working hours caused by labor shortages in the construction industry, the Ministry of Land, Infrastructure, Transport and Tourism is promoting the "Building BIM Acceleration Project" to spread the adoption and utilization of BIM. This project supports a portion of design and construction costs for architectural projects where multiple businesses create building BIM data. Particularly for small and medium-sized businesses that have not yet adopted BIM, utilizing this subsidy program can lower the barriers to BIM implementation.
