🔳Recommended for people like this

• For those who are facing challenges with the time required for drafting and measurement during tunnel and road inspections
• For those struggling with the accuracy and reproducibility of curved surface measurements and damage documentation
• For those who want to speed up communication with clients
• For those who want to improve their manual processes for as-built management and reporting

🔳Highlights of This Seminar

(1) The “Measurement Revolution” in Tunnel Inspection and Repair

When inspecting tunnels,

• Hand-drawn sketches
• The effort involved in creating drawings
• The Challenges of Curved Surface Measurement

This had been a major burden, butScanat under the initiative that introduced [...],

• Capture the entire tunnel as a 3D model
• Record cracks and damage as they are
• Curved Surface Measurement (R Measurement) Goes Digital, Too

This significantly reduces measurement work andimproves accuracy and reproducibility.

② National Highway Maintenance Operations That Eliminated “Round Trips to the Site”

In conventional national highway maintenance and repair projects, the back-and-forth process of on-site inspection → reporting to the government office → another on-site inspection resulted in significant time loss, which was a major challenge.

However,Scanat After implementation,

• On-site photography and 3D data acquisition
• Instant Cloud Sharing
• The client can verify and make decisions remotely

This shift in workflow has reduced the need for on-site trips and improved decision-making speed.

③ “Cloud Sharing” That Changed Communication with Clients

A key feature of this pilot project was the ability to share field data in real time.
By allowing users to upload 3D models directly from the field and share them via a link,

• Assessing the situation without going to the site
• Quick Decision-Making
• Reducing Unnecessary Travel

This made it possible to achieve a 58% reduction in on-site surveys and a 33% reduction in personnel.

④ Digitization of “As-Built Management”

For pavement repairs (patching),
Traditionally, this required multiple people to take measurements using tape and create drawings by hand, but

• Measurements on 3D Data
• Converting Area to Data
• Submit directly to the client

This change has led to a significant reduction in man-hours and a simplification of reporting procedures.
