What Office K1 does
Office K1 (オフィスケイワン株式会社) is a Japanese bridge-focused BIM/CIM software vendor founded in January 2014 in Osaka. The company develops a suite of NetIS-registered software systems that convert 2D CAD bridge drawings into 3D models without requiring 3D CAD expertise, addressing Japan's skilled-labor shortages and government-mandated BIM/CIM adoption in public infrastructure works.
The product portfolio centers on a foundational 2D-to-3D auto-modeling engine (Click3D) plus bridge-type-specific modules — CIM-GIRDER for steel bridges (NETIS KK-200014-VE, Reiwa 8 Recommended Technology), CIM-COMPO for PC girder bridges, CIM-BOX for PC box girder bridges, CIM-SLAB and Qa-Slab for deck work, plus Sim-BRANE for crane erection simulation, Sim-LOAD for transport logistics, Click-CCBOX for utility duct design, CIM-PDF for 3D model management, a VR safety education system, and Mebris metaverse construction simulation. The systems integrate with AutoCAD and Navisworks and serve bridge manufacturers, engineering consultants, and general contractors across the Japanese infrastructure market.
Office K1 operates a direct enterprise sales motion with annual subscriptions priced at ¥600,000–¥900,000 per license plus ICT modeling/professional services. The company has 36 staff (26 full-time), completed 150+ commissioned 3D modeling projects, sold 25 CIM-GIRDER licenses within five months of its May 2020 launch, and became part of Sugata Group Holdings in October 2024.

Office K1 competitors and assessment
Company assessmentDirect peers
- Forum8: Japanese developer of UC-win/Road, VR-Design Studio, and infrastructure design software serving the same domestic bridge and road engineering market. Most directly comparable Japan-based peer with overlapping BIM/CIM and VR safety training offerings.
- Bentley Systems: Global leader in infrastructure engineering software with OpenBridge Modeler and OpenRoads, the most direct competitor in bridge BIM/CIM modeling worldwide. Targets the same bridge designers and DOTs that Office K1 serves in Japan.
- Kozo Keikaku Engineering (KKE): Japanese engineering consulting and software firm with structural analysis and BIM-related offerings for civil infrastructure. Comparable Japan-focused engineering software vendor serving overlapping customer segments.
- Fukui Computer Architect: Japanese CAD and BIM software provider (TREND-CORE, ARCHITRAINER) widely used in Japanese architecture, construction, and infrastructure. Competes for the same Japanese enterprise construction software budgets as Office K1.
- Trimble: Tekla Structures and Trimble Connect provide structural BIM for steel and concrete bridges, including parametric modeling and detailing workflows. Directly competes with Office K1's CIM-GIRDER and Sim-BRANE offerings.
Broad incumbents
- Dassault Systèmes: Provider of CATIA and the 3DEXPERIENCE platform, used in large infrastructure and civil engineering projects globally. Broad incumbent in engineering design software rather than a bridge-specialty direct competitor.
- Nemetschek Group: European parent of Allplan, Vectorworks, and other AEC software brands. Operates broadly in the same BIM/AEC space but does not specialize in bridge-specific workflows like Office K1.
- Autodesk: Owner of AutoCAD, Revit, Civil 3D, and InfraWorks — the dominant broad BIM/CAD platform that Office K1's products integrate with and depend on. Represents both a platform partner and the largest incumbent threat to bridge-specialty tools.
- Hexagon (Bricsys): Provider of BricsCAD, Leica Geosystems surveying, and broader infrastructure software. Competes broadly in CAD/BIM and infrastructure digital workflows relevant to bridge construction.
Emerging players
- SmartScape: Japanese 3D visualization vendor whose SmartScape 3D PDF for Navisworks integrates with Office K1's CIM-PDF pipeline. Smaller, more specialized player in the same Japanese BIM/CIM ecosystem.
