▼Highlights of This Case Study
Implementation:Scanat with the goal of “capturing the entire site in a single session.”
Results: Design and estimating time was reduced by approximately 60%. This has created a system where even junior staff can handle large-scale projects.

About Toriu Construction Co., Ltd.
♦︎A local construction company that handles large-scale renovation projects
Toriu Construction Co., Ltd. is a community-focused construction company that specializes in residential renovations.
The company provides comprehensive services—from design and proposals to estimates—particularly for large-scale renovation projects.
Challenges Before Implementing Scanat
♦︎Inefficient Workflows Designed with Follow-Up Visits in Mind
Our previous operations faced the following challenges:
- Revisits occurred due to omissions in measurements and photography
- Hand-drawn drawings → Duplicate work involved in creating technical drawings
- On-site inspections are required for every design and proposal.
Particularly for large-scale projects,
the entire process—from the initial consultation to the proposal— required a significant amount of time , totaling approximately 32 hours.
How We Discovered Scanat and Why We Chose It
♦︎We want to eliminate rework during the design and quoting phases and keep our operations moving forward.
When creating drawings or reviewing proposal plans,
- Revisions Due to Inconsistencies After Drawing Creation
- Return Visit to the Site During the Proposal Phase
- Re-work due to insufficient information when preparing quotes
Such "rework in later stages" was a factor contributing to the increase in man-hours.
To improve this situation, Scanat “accurately capturing on-site conditions in a single pass to eliminate rework in subsequent processes.”
- Reducing the amount of verification work required when creating drawings
- Preventing the Need for Follow-Up Visits During Proposal Review
- Addressing Information Gaps When Preparing Quotes
The company was recognized for its ability to smoothly handle the entire process, from design to quotation.
Furthermore, since the system was implemented, the reduction in such rework has enabled even junior employees to handle large-scale projects, which has led to improved productivity across the entire organization.
Benefits of Implementation
♦︎Reduced working hours while improving our ability to handle projects
[Creating As-Built Drawings (Drawing Preparation)]
Before implementation: Took about 8 hours and required two people
After implementation: Reduced to about 3 hours
[Creating As-Built Drawings (Drawing Review)]
Before implementation: Took about 3 hours and required 2–3 people, including a sales representative and a supervisor
After implementation: Reduced to about 1 hour and can be completed by the supervisor alone
[Reviewing Proposed Plans]
Before implementation: Took about 8 hours to create
After implementation: Reduced to about 2 hours, resulting in a 75% cost reduction
[Quotation Preparation]
Before implementation: Took about 10 hours to prepare
After implementation: Reduced to about 4 hours, resulting in a 60% cost reduction
Future Outlook
♦︎Creating a Worksite Anyone Can Manage Through a “Design System That Eliminates Rework”
Scanat has significantly reduced rework and the need for re-verification in our design and proposal work,
transforming our workflow from one “based on the assumption of redoing work” to one “where we move forward on the first try.”
Going forward, we plan to expand our use of the system to handle a greater number of projects and streamline staff training.
