Our company provides inspection support technologies that contribute to the efficiency and advancement of bridge inspections, including the "Remote Automatic Photography System," "AI-based Deformation Analysis," and the deformation diagram creation support software "CrackDraw21." By analyzing image data of the deck, guardrails, piers, and abutments captured during inspections, we can detect and digitize deformations such as cracks with accuracy equal to or greater than visual inspections. We database inspection dates, deformation locations, types of deformations, and scales of deformations, enabling objective assessment of progression and visualization of these factors. Additionally, we support the creation of reports and linking with 3D models. 【Features】 ■ Capable of capturing extensive areas that are difficult to inspect visually or are inefficient to inspect in a short time ■ Safe inspections using non-contact, ground-mounted equipment ■ No need for rope work or aerial work platforms/bridge inspection vehicles during photography ■ Complies with the Ministry of Land, Infrastructure, Transport and Tourism's inspection guidelines for capturing cracks of 0.05mm in width ■ Applicable to large structures such as high-pier bridges ★ We are currently offering materials that provide an overview of this technology, along with reference information for selecting inspection support technologies.

"I can't find anyone to carry loads on my shoulders in the mountainous area." "I want to reform the way we work." "There isn't enough volume to use helicopter transport or monorails, but since there are no other means, costs are increasing." "I want to minimize the logging area and consider the environment." These are the voices being raised on-site. At Higashi Setu Civil Engineering Consultant, we offer a 'Heavy Load Transport Drone' service that can transport heavy items with agility. The 'Heavy Load Transport Drone' does not require large-scale temporary setups, allowing us to respond quickly to sudden requests. While a minimal takeoff and landing space is necessary, it has a smaller environmental impact compared to helicopters and monorails. By placing operators at both takeoff and landing sites, we can also accommodate transport to locations that are not directly visible from the takeoff point. From the perspective of prioritizing safety and rapid response, we recommend flying within visual line of sight ("visual flight: within 0.8 km"), but we can also accommodate flights beyond visual range with a separate permission application period. We already have various transport achievements, including support materials weighing 30 kg, a one-gallon can weighing 49 kg, deer protection fences, and long items like 3-meter single pipes, and we can handle a variety of cargo shapes.
