EuroSDR – research association of
European National Mapping and
Cadastral Agencies (NMCAs)
Objectives
Developing a coherent approach to GeoBIM integration
- with consensus between multiple stake-holders from both the Geo and the BIM side.
- at international level (share national experiences)
Join efforts to improve the state-of-art
Develop initial solutions for better integration:
best practice
for Geo-data in BIM processes and software
And
for BIM data in Geo-data processes and software
Use data from practice, and not “academic” and “clean” IFC models
(modelled as expected, without errors).

Discussion
Investigating the State of Play of GeoBIM Across Europe
Questionnaire – Current Status, Awareness and
Activities • Mixed picture in terms of awareness
• Most countries see added value of linking Geo-BIM (research
or governmental programmes)
• Fragmented picture in terms of activities – very little
centralised GeoBIM integration strategy work at national level
• More work being done at project/company level
Non-Technical Challenges:
•Lack of GeoBIM Awareness and Knowledge
•Lack of Investment
•Disciplinary Divide: Geographers, Architects, Engineers
Technical Challenges:
•Lack of Software to support both BIM and Geo
•Lack of Standards
•Different Conceptual Models
•Interoperability Challenges
•Lack of BIM Data Sources

- Analysis of current practice
- Analysis of where current practice can be improved w.r.t. automation using a
combined Geo and BIM approach
- Specifying geo- and BIM data needs in order to (partly) automate the building permit
process / support the life cycle asset management
- Experiments to show the improvements
• with respect to semantics
• with respect to geometry
• with respect to georeferencing
• with respect to accuracy
• with respect to LoD

Tests in northern Sweden using CoClass
(national standard) and IFC (e.g. toilet size for
wheelchair use)
New project with building permits

3 checks: BIM only, manual, BIM+Geo
60% of municipalities have joined
common online service for building
permit applications and bigger
municipalities have their own systems

Research
questions
and next
steps
Select regulations that benefit from GeoBIM integration
e.g. Right of sun; Shading; Zoning; Maximum height; Fire (distance to hydrants,
roads, evacuation areas)
Based on these:
• Distinguish between different types of buildings?
• Distinguish between new building or changing buildings?
• Metadata issue
• Accuracy issue
• Georeferencing issue
• Level of detail issue
• Level of development issue
On-going interviews and collaborations with Municipalities and involved stakeholders to
answer these
(Cities of Den Haag, Rotterdam, Almere)

Conclusions &

Workflow draft:
Need to employ PLCS standard
Still preliminary questions:
• What data asset managers need?
• Can be geoinformation the link between different asset managers?
• …
Conclusions
Common requirements enabling the interoperability: • Valid Geometry
• Valid topology
• Valid Georeferencing
• Standardised and complete semantics
Common Issues: • Software
• Georeferencing and CRS (especially for BIM/IFC)
• Standard versions
• problems with large datasets
Issues linked to the use case 1:
Many different institutions giving different permissions
Regulations have to be translated into digital (spatial) format
Need to promote the solution finding benefits for stakeholders to comply to standards:
• We can then accelerate the planning process and permission issuing
• Enhance objectivity in the evaluations
Specific tools / guidelines are needed
