Tokyo, November 14, 2025 – Hitachi, Ltd. (TSE: 6501, hereafter Hitachi) announces that its Connective Industries Sector (hereafter CI Sector), a sector with deep expertise in on-site operations at both its own and customers' facilities, is driving initiatives to enhance workplace safety and operational efficiency. Recognizing these as critical management priorities, the CI Sector is committed to delivering solutions that strengthen performance and create safer, more productive environments. Hitachi Building Systems Co., Ltd. (hereafter Hitachi Building Systems), part of CI Sector, together with its group companies*1 are developing an AI-based safety solution for field engineers to improve work efficiency and safety, under the principle that “Safety and health should always come first.” This initiative is part of the value offered by digital service HMAX for Buildings: BuilMirai, which embodies Lumada 3.0.
As the first phase of the development project, on-site operations will begin in late November 2025, following the completion of a feature that can alert users to dangerous locations using QR codes, wearable cameras, and smartphones (the safety alert feature).

The safety alert feature to be deployed in the field emits a sound from a smartphone when a camera worn by an engineer detects a QR code on a sign. These signs will be installed at every hazardous location on worksites. Traditionally, field engineers identify dangerous areas through pointing and calling during work. This feature aims to further enhance safety awareness by using sound to prompt engineers to reconfirm potential hazards.
The rationale behind the limited initial rollout of this feature is to help engineers adapt early to new workstyles involving wearable cameras and audio notifications, while minimizing their workload.
The system is designed to be scalable, anticipating future functional enhancements. Information captured via wearable cameras will be utilized for various safety measures.
In launching the safety alert function, we will prioritize both the safety of on-site engineers and the improvement of operational efficiency. At the same time, we will give due consideration to protecting the privacy of general building users and other individuals.

The labor shortage issue is becoming more serious in the construction and building management industries. Today, skilled engineers and beginners work together on site more frequently. Hitachi's building system business includes approximately 26,000 frontline engineers, the largest within CI Sector. Hitachi positions the improvement of safety and work efficiency as critical business challenges, as it is a business with strengths in on-site operations.
To respond to this challenge, the Hitachi Group converts the valuable knowledge of field engineers into data to promote the development of AI-based solutions. Hitachi Building Systems is engaged in the development and practical application of AI-based safety solutions as part of the value offered by the digital service HMAX for Buildings: BuilMirai. The company aims to integrate features such as generative-AI-based document creation support, dangerous location alert, and remote monitoring of work to create an environment where anyone can work safely and efficiently.
By linking this initiative with previously introduced measures and leveraging abundant field experience, Hitachi will contribute to workstyle reforms for engineers in the field and working at manufacturing sites around the world. These efforts will extend beyond the Hitachi Group.
Additionally, Hitachi will introduce a system that enables managers and skilled supervisors to view fieldwork video remotely in real time. This will enable them to accurately understand the status of work and give instructions and advice if needed. By combining digital technology and skilled supervisors' experience and knowledge, Hitachi will construct a new structure in which the entire team can provide support without isolating field engineers.
These initiatives will aid the transfer of technology and the development of human resources as well as improve the safety and quality of work.

Hitachi's CI Sector, to which Hitachi Building Systems belongs, focuses on “Integrated Industry Automation,” which aims to expand “HMAX Industry” into growth industries horizontally. HMAX Industry provides digital services that combine data from an abundant installed base of products (digitalized assets), domain knowledge, and advanced AI. As part of the CI Sector, Hitachi Building Systems aims to drive innovation for frontline engineers and contribute to improving people's well-being through the delivery of “HMAX for Buildings: BuilMirai” that embodies Lumada 3.0.
