「We updated our proprietary three-dimensional structural analysis software, WOLF-3, to support SE Construction Method Ver.3 and accelerated its calculation processing. We are also working to support timber post-and-beam construction methods other than the SE Construction Method and large-section timber structures, and are developing the software as a structural calculation system that can be used throughout our Group.」
WOLF-3 was updated to support SE Construction Method Ver.3 and its calculation processing was accelerated. Development is also progressing to support timber post-and-beam construction methods other than the SE Construction Method and large-section timber structures. - FY2025AdvancedAnnual report
「To strengthen our ability to address increasingly diverse and larger-scale timber buildings, we obtained a new structural performance evaluation for the SE Construction Method, BCJ Evaluation LW0078-04, dated 1 April 2025, which also addresses the tightening of the Building Standards Act in 2026. The new structural performance evaluation enables SE Construction Method Ver.3 to expand the method’s scope of application and improve design flexibility through enhanced performance.」
Obtained a new structural performance evaluation for SE Construction Method Ver.3 dated 1 April 2025, expanding its scope of application and enhancing its performance. - FY2024AdvancedAnnual report
「We developed a structural calculation system to address the diverse needs of increasingly large-scale and complex timber buildings, and developed software to perform structural calculations for five-story buildings. We are also working to support timber post-and-beam construction methods other than the SE Construction Method and large-section timber structures, and are developing the software as a structural calculation system that can be used throughout our Group.」
The company is advancing WOLF-3 to support five-story buildings and is developing it to support timber post-and-beam construction methods other than the SE Construction Method, as well as large-section timber structures. - FY2022AdvancedAnnual report
「In February 2022, we opened the Timber Structure Technology Center (Timber Lab), an experimental and research facility for timber structures.」
An experimental and research facility for timber structures was opened in February 2022. In addition, the company is conducting fire-resistance verification of joints, enhancing WOLF-3 functionality and developing the SE Construction Method for five-story buildings. - FY2021AdvancedAnnual report
「Development of the SE Construction Method for five-story buildings To accommodate five-story buildings, we are conducting structural studies and developing the SE Construction Method.」
As part of its R&D activities, the company explicitly addressed five-story buildings and is conducting structural studies and developing the SE Construction Method. It also described evaluation testing of laminated cedar timber and enhancement of WOLF-3 functionality. - FY2020SoftenedAnnual report
「Completed frame testing and evaluation testing of joints using hardware based on new technology, and is developing CAD software for practical use.」
The filing states that joint testing has been completed and CAD software development is continuing, but does not specify the previous target completion date of March 2020. - FY2019First statedAnnual report
「Development of joints and software for SE Construction Method Ver.3 (target completion date: March 2020)」
Completed joint testing using new hardware and developed CAD software for operational use. In addition, the company is developing the WOLF-3 structural calculation software, which has no restrictions on floor-plan or elevation shapes, as well as earthquake simulation software.
