Promoting Digital Transformation in Yokosuka City: Streamlining Design and Construction Management Through 3D Scanning

Here is a case study on the use Scanat at Yokosuka City Hall.
The Yokosuka City Urban Development Department, which is responsible for the renovation and maintenance of public facilities in Yokosuka City, Kanagawa Prefecture, has introduced " Scanat," a 3D scanning app for iPhone and iPad, with the aim of streamlining on-site surveys, reducing the workload on staff, and improving services for citizens.

Background
In renovation projects for public facilities, existing drawings are often incomplete. In the past, reliance on photographs and manual measurements led to omissions in dimensional measurements and the need for additional on-site surveys. Furthermore, preparing the documentation required for design and cost estimation was time-consuming, and the inability to fully utilize the information gathered on-site posed a significant challenge.

How to Use

• Understanding Site Conditions: Use 3D models to intuitively verify site conditions and the details of renovation work
• Measurement: Calculate accurate dimensions and areas from scan data
• Scanning: Perform a 3D scan of the entire site in just a few minutes, create a model on the spot, and use it to verify design plans and construction progress

Pros

• Ease of use: It’s easy to get started, and since on-site conditions are immediately converted into 3D models, it has been well received by staff
• Improved information sharing: By using 3D models, stakeholders can intuitively understand and share design details and renovation plans.
• Proven Track Record and Trust: Since its introduction, the system has been utilized in multiple public facilities, contributing to greater efficiency in design and construction management.
• Application to Maintenance and Repair Planning: By utilizing the acquired 3D data for long-term building management and repair planning, we can expect to improve efficiency and the accuracy of decision-making in the future.

Scanat is gaining traction not only as a way to make on-site surveys and explanations to customers more understandable, but also as an initiative that contributes to the future maintenance and management of buildings.
We will continue to provide support so that the use of 3D data can contribute to the creation of safe and comfortable communities.
