Offering Sumaho DE Zumen as Ichigen-cho Lite, with pricing now published

DiO inc. is offering Sumaho DE Zumen (smartphone floor plans), announced on October 6, as Ichigen-cho Lite
We have also published its pricing

Ichigen-cho starts at a low cost and grows from there, using PLATEAU data (3D city models) from Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and LINE, the app everyone uses
Ichigen-cho Lite is the easy entry point
You can apply through LINE, with no dedicated app needed (a payment card must be registered when you apply)
It also opens in a web browser

Main functions

• Import photos taken with a smartphone
• Storage by building
• Sharing (view and hand over)
• Photos can be saved one at a time, and the approximate floor plans made with Sumaho DE Zumen can be viewed on screen and printed

Pricing

• If it does not suit you, the first month is refunded (monthly payment, within 30 days)
• Even if you switch from Sumaho DE Zumen to Ichigen-cho Building Maintenance, your photos and data can be used as they are

Option: 3D view (PLATEAU)

• JP¥300 per building per month (excluding tax)
• Because it uses PLATEAU data from Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT), there is no cost to build a 3D model from scratch

Details

How to start with PLATEAU data from MLIT and LINE, and the pricing, are shown on the Ichigen-cho Building Maintenance page

Adding the Sumaho DE Zumen (smartphone floor plans) function to Ichigen-cho Building Maintenance

DiO inc. is adding the Sumaho DE Zumen (smartphone floor plans) function to Ichigen-cho Building Maintenance, its cloud service for building management
The function creates floor plans (drawings) of building interiors from photos taken with a smartphone

Sumaho DE Zumen uses AI to automatically create a floor plan of each floor from smartphone photos
It makes it easy to understand where rooms and equipment are, right inside Ichigen-cho

Main features

• AI automatically creates a floor plan of each floor from photos taken with a smartphone
• It can be used from within Ichigen-cho, and the finished floor plans are placed directly in the drawings section of Ichigen-cho
• The building exterior can be checked with the 3D view function (option) that uses PLATEAU from Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT)
  Use the 3D view for the exterior and Sumaho DE Zumen for the interior floor plans

Before you use it

• The floor plans are provisional drawings (approximate) for understanding positions, not accurate drawings like as-built drawings*
  The screen also shows that they are approximate
• They cannot be used for statutory inspection records or for guidance on evacuation routes or fire extinguisher locations
• Take photos only within the scope permitted by the building owner or manager
  Do not photograph other tenants' rooms, people's faces, documents or computer screens
• If you need drawings accurate down to the dimensions, please import as-built drawings* or use DiO's CAD conversion (3D modeling and drawings for equipment without drawings) (charged separately)

We are currently preparing to launch it
Pricing and the launch date will be announced separately

Ichigen-cho Building Maintenance page

*As-built drawings: drawings handed over by the construction company when a building is newly built
Most are kept on paper, and turning them into PDFs requires a paid scanning service, for example through a building maintenance company
The information is accurate, but after years of renovations some parts may differ from the actual building
