Early detection of heatstroke risk! We support workers' health management with a dedicated wristband!

【NETIS Registration Number】KT-240128-A "GenVital LTE" is a system that supports the health management of field workers by instantly notifying both the work manager and the worker themselves with an alert when indicators calculated by the health management judgment algorithm developed by Obayashi Corporation exceed set thresholds. These indicators are based on heart rate and location data collected through a wristband, as well as the heat index at the construction site. <Standard features specialized for the health management of field workers> ⚫︎ Four-level indicator display ⚫︎ Fall detection* ⚫︎ SOS signal from the wearer* ⚫︎ Location data acquisition ⚫︎ Automatic collection of heart rate and heat index ⚫︎ Daily/Monthly report output *Currently under development. With the revision of the Labor Safety and Health Regulations coming into effect on June 1, 2025, businesses will be required to implement measures against heatstroke. The use of wearable devices is also recommended to quickly identify workers at risk of heatstroke. "GenVital LTE" is a device that quickly detects the risk of heatstroke and is suitable for the safety management of field workers! Please feel free to consult with us.

Reduce working hours by approximately 50-70%! Significant improvements in productivity and work efficiency with AR rebar inspection that can be conducted by one person.

【NETIS Registration Number】CB-230022-VE 'BAIAS' is an AR system for rebar inspection of reinforced concrete structures that allows a single person to easily conduct inspections using a tablet. By automatically measuring the number, diameter (thickness), and spacing of rebar from images taken with a tablet, it significantly reduces the time and effort required for inspections. This system enables what was traditionally a multi-person task of inspecting rebar in reinforced concrete structures to be performed easily by one person, contributing to labor-saving and efficiency on site. 【Features】 ■ Measurement of rebar spacing is possible even with double rebar ■ Supports measurement of cover thickness ■ Contributes to labor-saving in the inspection process with the electronic blackboard function ■ Reduces preparation and work effort with the two-point measurement function *For more details, please refer to the PDF document or feel free to contact us. *This product is for the domestic market.

• Reinforced concrete construction

For tunnel construction and night work! Displaying highly visible virtual signs to contribute to safety management.

The Virtual Sign is a system that projects pre-set signs from a high-brightness light source mounted on the main device, by setting the signs in advance on the cloud at the site office or similar locations. By brightly and clearly projecting signs at tunnel construction sites or nighttime construction sites, it effectively informs site workers of restrictions and raises awareness. Various sign contents for use at construction sites are prepared, and the display content can be changed remotely via the cloud, reducing the hassle of installing or replacing signs and leading to labor savings. The main device is equipped with a communication terminal, and the connection to the cloud can be selected from LTE, wired LAN, or Wi-Fi. It is also possible to project sensor information and surveillance camera footage installed at the communication site via the cloud. Additionally, it has dustproof performance that allows it to be used without impact in tunnel construction, as well as waterproof performance for use in rainy weather. By projecting images from a high-brightness light source, it is possible to create large and clear sign displays, similar to projection mapping, by installing the device in locations that do not obstruct vehicle traffic.
