🔳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 this,

• Capture the entire tunnel as a 3D model
• Record cracks and damage as they are
• Curved Surface Measurement (R Measurement) Has Also Gone Digital

This significantly reduces measurement work while improving 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 verifies and makes decisions remotely

This shift in process 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 instantly share on-site data.
By uploading 3D models directly from the site and sharing 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”

In pavement repair (patching),
Traditionally, this required multiple workers 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 tasks.
