A new International Construction Technology Interoperability Standard is advancing toward cross-vendor data alignment. Pilot programs launched in late 2025 include major BIM software providers and equipment manufacturers, aiming to unify data formats, APIs, and semantic definitions across design, construction, and digital-twin systems. The initiative seeks to reduce rework and improve model fidelity by enabling seamless data flow-such as sensor data, material specifications, and project schedules-through digital workflows.
Background
Interoperability has been a persistent challenge in construction technology. Open standards like BIM's Industry Foundation Classes (IFC) and ISO 19650 offer a foundation for vendor-neutral data exchange. IFC, maintained by buildingSMART, has progressed through several versions, with IFC 4.3.2.0 approved in April 2024 as ISO 16739-1:2024. This version allows software certification and enhances semantic data exchange. ISO 19650 defines processes and requirements for BIM information delivery, with a recent extension-Part 6-covering health and safety information in 2025. These standards provide the basis for the new initiative's effort to establish a unified interoperability layer.
Details
Pilot implementations include several BIM software firms and hardware manufacturers in the concrete, electrical, and HVAC sectors. These groups are testing unified data mapping, version control, and provenance tracking across systems. ROI assessments of the pilots report reduced integration costs, faster project handoffs, improved predictive maintenance, and enhanced risk management due to traceable change histories.
While existing standards such as IFC and ISO 19650 offer a solid basis, the new interoperability standard aims to simplify practical deployment in a fragmented vendor landscape. However, critics warn that inconsistent adoption-particularly among subcontractors and across regions-could affect compliance and reduce benefits. Regulatory and procurement incentives favoring interoperability over vendor lock-in are likely to influence broader adoption.
Outlook
As governments and industry groups weigh mandates and incentives for interoperable systems, the industry is monitoring whether pilot projects will lead to widespread procurement requirements and project-level commitments. The adoption of this new standard may determine how quickly integrated BIM and digital-twin workflows become mainstream globally.
