＼Kentsu Technos is using it too!／ Scanat: Complete on-site surveys “with just a smartphone and by yourself”

■About Kentsu Techno Co., Ltd.

・As a construction professional, how can we streamline the ancillary task of "asbestos surveys"?

Kentsu Techno Co., Ltd. is a specialized construction contractor that handles a wide range of projects, including building construction, painting, and waterproofing.

Due to recent legislative changes, "pre-construction asbestos surveys" have become mandatory and are now an unavoidable part of any construction project.

The challenge is to find ways to streamline our operations while maintaining the accuracy of our surveys, without disrupting our core business of "construction and renovation," which is where our primary focus should lie.

■Challenges Before Implementing Scanat

・The limitations of "manual preliminary research," which requires significant manpower and time

Our traditional business processes faced the following challenges:

• In addition to the inspector, a contractor must accompany them (two-person team)
• On-site work that takes a total of 90 minutes just for visual inspections and taking photographs
• The heavy administrative burden of creating photo logs (120 minutes) and preparing survey reports (90 minutes) after returning home

In particular, "on-site inspections conducted by a team of two" involved significant scheduling costs and had become a bottleneck in improving overall organizational productivity.

■How We Discovered Scanat and Why We Chose It

・The deciding factors were the precision that allowed me to shoot everything on my own and the ease of explaining the process

The decision to implement the system was driven by a desire to prevent reliance on individual expertise in field operations and to promote the automation of administrative tasks.

• One person, done in no time: Simply scan to capture the entire site
• Eliminating the Need for Photo Organization: A Shift to Extracting Necessary Sections from 3D Models
• Smooth Consensus Building: By sharing 3D models, work plans can be explained without the need for follow-up visits

Recognizing these benefits, we decided to implement the system with a view to utilizing it in a wide range of applications, from asbestos surveys to pipe renovations and the selection of materials for interior construction.

■Benefits of Implementation

・On-site work reduced to 20 minutes. Administrative tasks have also been dramatically sped up.

Since its implementation, we have seen a dramatic reduction in the amount of work required, particularly for preliminary asbestos surveys.

[Total Time Required for Preliminary Site Surveys]

• Before implementation: 180 minutes (3 hours total with a two-person team)
• After implementation: 20 minutes (completed by a single person) ⇒ Approximately 89% reduction

[Time Required to Prepare Preliminary Investigation Records]

• Before implementation: 270 minutes (photo log + report preparation)
• After implementation: 45 minutes (no photo log + report only) ⇒ Approximately 83% reduction

"Because we can share site conditions using 3D models, explaining work plans goes more smoothly, which helps reduce unnecessary return visits and travel, " they say, noting that the benefits go beyond just the numbers.

■Future Outlook

・From surveys to renovation plans, 3D data is transforming construction sites

Scanat is proving invaluable in a wide range of applications, from asbestos inspections to assessing water leaks anddeveloping pipe renovation plans.

Because we can accurately capture the current state of the site in 3D, we are now able to prevent mistakes in material selection.

Going forward, we plan to leverage this high-precision data to further advance digital transformation in the field.
