M5 Data Metric Summary
Copenhagen Metro
Responsible for developing and building the metro system in Copenhagen, Denmark.
Responsible for enhancing customer experience to support city mobility and environmental goals through innovative solutions.
Overcome boundaries of interoperability and to never be limited to specific software.
Standardized and consistently structured data as a foundation to increased data reliability, automations routines and assist us in making data-driven decisions.
CDE supports open collaboration among different disciplines, ensuring that all design-related information is shared and coordinated across all stake-holders.

Database & Data Exchange
Benefits • Normalized schema
combining OIS classification and IFC structure.
• Exportation routines created to generate documentation to be saved on ACC and shared with consultants in excel format.

Challenges
• Not possible to clash a model against the same model.
Metro is using Navisworks to overcome limitations of ACC when selecting models to be tested.

OpenBIM Challenges
• Not all software were able to export to IFC 4.3
and others only with IFC 4.3 beta exportation.
IFC 4.3 Formally Approved and Published as an
ISO 16739 Standard. April 2024.
• Not all the domains were available in the
export settings in version 2023.
Autodesk has integrated the functionality of
Domain selection in their export settings in version
2025.
• Not possible to create the custom
USERDEFINE for the IFCTypeEnum in version
2023.
Autodesk has integrated the functionality to add
custom USERDEFINE in version 2025.
Conceptual Design Phase
• BCF import is only supported on a single
IFC or RVT file.
• Attachments are not supported.
• Custom status are not supported. All issues
are imported as "Open" status unless they
are explicitly defined as "Closed" in the BCF
file.
• Issues can't be imported into more than one
project in ACC.
• BCF files created in Navisworks, or any
other software give error when importing in
ACC even with version 2.1
All the generated information is communicated
through ACC. One issue is created per
Federated Model with attachment of report and
dashboard.

Analysis Report A total of 116 IFC files with 57.468 objects were checked. The review scope consisted of: • Compliance of implementation of OIS object
naming. Result: 94,13% Pass 5,87% Fail. • Compliance of implementation of IFC Type. Result: 96,76% - Pass 3,24% Fail. • Compliance of implementation of OIS and IFC
Attributes. Result: 90,88% - Pass 9,12% Fail.

OpenBIM 2025-2026
• Leveraging our IFC data to inform all BIM Uses (3D Coordination, Design Review, Costing, Scheduling, Sustainability).
• Exploring translating .IFC into .JSON or other formats to increase the query speed on large federated models.
2
IFC and BIM Uses • Integration of bSDD with
our MS Database and providing easy access to consultants to our data and to benefit from open- source classification add ins.
3
bSDD • Adding more data
visualization and checks for data in our models to verify compliance.
• Further improving IDS capabilities and integration with bSDD.
4
BCF • Leveraging BCF to
overcome limitations of ACC and promote openBIM communication.
• Further work on refining OIS Classification System based on feedback and requests from our consultants with a streamlined workflow in place.
• Utilizing IFC domains to be able to use them in combination with our OIS classification.
