Aug 27, 2025
Sekino Kosan,Inc. (hereinafter referred to as “Sekino Kosan”) and Nippon Steel Trading Corporation (hereinafter referred to as "our company") have jointly developed and launched “Dommit for Bankin Mate,” a new system that connects Sekino Kosan’s estimation system “Bankin Mate” and our company’s platform software “Dommit.” The new system aims to capture demand for refurbishment projects while addressing challenges faced by the architectural sheet metal industry.
Sekino Kosan’s “Bankin Mate” is an estimation system provided to architectural sheet metal contractors since 1995. The “CAD edition” enables material takeoff based on exterior photos and drawing data, while the “Estimation edition” supports a wide range of operations, including cost and project management, as well as preparation of quotations and invoices.
Meanwhile, our company’s “Dommit” is a platform introduced in May 2023, specifically for architectural sheet metal contractors engaged in metal exterior renovations such as roofing and wall panels. Dommit generates 3D models from drone-captured images, enabling end-to-end streamlining—from material selection to estimation and quotation—while improving worksite safety.
By integrating the diverse functions of “Bankin Mate,” which has long responded to users’ needs, with the latest DX tool “Dommit,” featuring drone-based measurement capabilities for roofs and exterior materials, this initiative addresses industry challenges such as labor shortages and workforce aging. It further enhances the efficiency of on-site surveys and quotation work for refurbishment projects.
In addition, following the March 2023 notification(in japanese) from the Ministry of Land, Infrastructure, Transport and Tourism, safety verification is required in cases where structural safety is not obvious. Therefore, Sekino Kosan will also utilize our company’s “Structural Confirmation Service” to confirm the structural integrity of buildings.
Going forward, both companies will continue to deepen their collaboration and strengthen the provision of solutions to capture refurbishment demand and resolve challenges in the architectural sheet metal industry.
