▼Highlights of This Case Study
Implementation: Aiming for a workflow that “captures the entire site in a single visit,”Scanat
was implemented. 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.
ScanatChallenges Before Implementation
♦︎Inefficient Workflows That Assume Repeat Visits
Our previous operations faced the following challenges:
- Return visits 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.
ScanatHow We Discovered It and Why We Adopted It
♦︎We want to eliminate rework during the design and quoting phases and keep our work moving forward
When creating drawings or reviewing proposal plans,
- Revisions Due to Inconsistencies After Drawing Creation
- Revisit 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, based on the principle of “accurately capturing on-site conditions in a single pass to eliminate rework in subsequent processes,”Scanat we implemented [the system].
- Reducing verification tasks during drawing creation
- 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 quoting.
Furthermore, since its implementation, 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
♦︎ Reduce working hours and improve project response capabilities
[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
♦︎A “design system that eliminates rework” to create a workplace that anyone can manage
ScanatThe implementation of this system 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 having to redo 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 growing number of projects and streamline staff training.
