About The Customer

The customer in this case study is 'Itoya', one of the largest stationary stores in Japan, established in 1904. Itoya has two main stores in Ginza, the central part of Tokyo, and a total of nine stores across the country. The firm specializes in stationery and is popular and famous in Japan. Each floor in the stores is dedicated to different types of products, such as expensive stationaries for writing or notebooks. The customer requested the renovation of the two main stores and another one in Yokohama, which amounted to five floors’ interiors.

The Challenge

Ikeda architectural design, led by architect Yoichiro Ikeda, was tasked with the renovation of 'Itoya', one of the largest stationary stores in Japan. The challenge was to simultaneously renovate multiple stores, including two main stores in Ginza, Tokyo, and another in Yokohama. The renovation involved swapping different floors between the two Tokyo stores while refurbishing all the floors at the same time. The renovation mainly consisted of designing new shelving and display islands, with the floor, wall, ceiling, and lighting remaining as they were. The schedule for the renovation was extremely tight, adding to the complexity of the project. The firm was uncertain if they could meet the deadline, and there was a need for a solution that would ensure timely completion and client satisfaction.

The Solution

The firm implemented a full-scale Building Information Modeling (BIM) operation using Archicad to manage the renovation project. The BIM design allowed the firm to create more detailed visuals than just 2D drawings, including texture and materials, helping the clients understand the proposed design content in the early stage. The firm was able to design the space and the furniture after the first meeting with the client, and by the second meeting, they provided renderings and walk-throughs with BIMx. The firm responded swiftly to changes using Archicad, and the client confirmed those changes by viewing the 3D models. The communication between the architect and the client was seamless and fast, and the wishes of the client were incorporated accurately. The 3D models of the fixtures and the furniture created for this project were stored as a 3D object database, allowing for quick responses to any additional renovation requests by the client.

Operational Impact

The implementation of BIM design using Archicad greatly improved the operational efficiency of the renovation project. It allowed the firm to create more detailed visuals than just 2D drawings, which helped the clients understand the proposed design content in the early stage. The firm was able to respond swiftly to changes using Archicad, and the client confirmed those changes by viewing the 3D models.
