Office K1 Co., Ltd. (Headquarters: Nishi-ku, Osaka; Representative Director: Keiichi Yasuda) announces that its steel bridge CIM system "CIM-GIRDER" has been selected as a recommended technology for FY2026 by the Ministry of Land, Infrastructure, Transport and Tourism's New Technology Information System (NETIS). This technology leverages 3D models in steel bridge detailed design to enhance design review sophistication and facilitate smoother consensus building among stakeholders. By reflecting this in technical proposals for comprehensive evaluation bidding methods and construction performance evaluations, it is a technology that contributes to improving the evaluation of design work for construction consultants and bridge manufacturers.
CIM-GIRDER Recommended Technology Selection
1. Background
In recent years, while more companies are utilizing BIM/CIM in steel bridge design, issues such as inconsistencies between design drawings, rework during the construction phase, and recognition discrepancies among stakeholders still persist. Furthermore, with the promotion of i-Construction 2.0, the importance of utilizing 3D data from the design stage is increasing.
2. Technology Overview
"CIM-GIRDER" is a 3D model-based design support system for steel bridges, featuring the following characteristics:
(1) Simple operation through numerical input, ideal for first-time steel bridge BIM/CIM adoption.
(2) Automatic modeling function for auxiliary components reduces inconsistencies between drawings and contributes to improved accuracy in design review.
(3) Visualization through 3D models facilitates structural understanding and accelerates consensus building with stakeholders.
This allows for solving challenges that were difficult with conventional 2D drawings at the design stage.

3. What is a Recommended Technology?
A recommended technology in NETIS is positioned as an "innovative new technology selected to further enhance the technical standards of public works, etc." Its utilization in technical proposals for comprehensive evaluation bidding methods is encouraged, and it is a technology that directly impacts client evaluations. Recently, it has become possible to propose the use of recommended technologies even after contract signing, increasing the importance of utilizing recommended technologies as a differentiating factor in future technical proposals.
4. Introduction Benefits
This system can be utilized across the design and construction processes, with the following benefits:
[Designers: Construction Consultants]
(1) Improved persuasiveness in technical proposals (backed by NETIS recommended technology).
(2) Increased productivity through efficiency in design review work and reduction of rework.
(3) Accelerated consensus building with clients.
(4) New creation of "design information attribute files" along with 3D models (for plate girders).
[Constructors: Bridge Manufacturers]
(1) Reduced risk of defects through 3D interference checks, including auxiliary components.
(2) Advanced planning work for subsequent processes such as painting diagrams, transportation, erection, and temporary structures.
(3) Contributes to improved productivity in the manufacturing process by streamlining full-scale work using "design information attribute files."
(4) Contributes to improved constructability verification and reduced rework risk through construction studies using 3D models.

5. Future Developments
To further promote the widespread adoption of CIM-GIRDER, we will provide implementation support and operation training for construction consultants and bridge manufacturers, as well as individual proposals and verification support with an eye towards application in actual projects. Furthermore, by accumulating case studies of application in actual projects, we will contribute to the advancement of BIM/CIM utilization in the bridge design field.
6. About Office K1
Supporting "bridge builders" with "digital technology," Office K1 has been providing information services utilizing advanced digital technology since its founding in 2014. It operates in three business areas: product sales of interoperable bridge BIM/CIM systems, and PoC development to pioneer new problem-solving.
In 2018, a project focused on improving productivity at construction sites received the "1st Civil Engineering Award Special Prize" in the Nikkenren Awards 2020. Additionally, a lecture presented at the 2025 Japan Society of Civil Engineers National Conference Annual Academic Lecture Meeting received the "Kakehashi Award" for FY2025, earning high praise within the industry for its advanced initiatives.
Moving forward, we will contribute to our customers' social infrastructure businesses through system development that truly contributes to productivity improvement.
