Challenges and experiences to implementdigital building application and permission in
Finland
IFC model checking using artificial intelligenceand idea of supplementing city model
All official documents and opinions in one place 24/7Master plann, data , archive
Easy to contact and ask from building controll
No working ours restrictions
All plans, discussions and comments open for participants
Everyone has uppdated plans in use
On the backround all official databases/maps/plans
Faster and more accurat process
No printing, less meetins in building control officeEasy correction of plans
Site inspection noticies directly documented
Possibility to 3D processes and new tools
26.2.2020 11
BenefitsBuilding control and officials
Same updated database for all
Simultanious opinions at the same time (fire department, road access, pipelines etc.)
Possibility to work and independent of working ours and place
Better control of working list
Possibility for deputies to help during vacations
Faster and more accurat processes
Possibility to contact ans ask all the time to planners and ownerNo papers and elecronical archive all the time in useSite control can all be done on site. No extra writing in office.Efficency grows 30 %. Less personnel, less space, happy personnel (possibility to work home) In future 3D model checking (Solibri) and comprehensive City Model
Online BIM processing
Internet of Spaces®
Big Picture – Trends on the Market:
Building Industry in 3D
Since 1994Open BIM model
Format: IFC
-
Mapping Industry in 3D,
Since 2001, Open City ModelFormat: CityGML
Internet of Spaces®
Open Standards to be Used
CityGML
IM3 IFCRoad, Landconstruction, Structuresbehind the surfaces –pipes, lines
Building Model,Structures, Materials,Features
All visible surfaces ofCity
ISO 16739
ISO 19107ISO 19109
CityGML = OGC (Open Geospatial Standard) GML 3
IFC = BuildingSmart standard
IM3 (InfraModel3) = based on LandXML, Now part of BuildingSmart development
Internet of Spaces®
CityGML defines not only buildings, but all visible city structures in
- Virtual Building Inspection, and in same environment

BIM-based buildingpermit process
Vantaa experinces
Education
In january 2019 Vantaa’s building permission department officersparticipated in ”BIM basics” courseBIM-coordinator is permanently at office
Solibri Automated checking up to 70 %Solibri is a originally Finnish software for IFC model checking, acquired by Nemetcheck, Germany
Rule base checking• Automated checking is based on rules
• Algorithms on the background analyzes all model components• Component dimensions• Collisions• Property values• Behavior• Relations
• Rules are collected into Rulesets• A Ruleset can consist of several sub
rulesets• Default ruleset of roles are included
in the installer• Rule parameters can be edited and
saved within the model
We are using Solibri rules for apartment buildings and private houses made specifically for building permission office and using Finnish building law requirements
