HYPOTHESE
Automatische data check bij data overdracht zorgt ervoor dat:
Betere data beschikbaar komen
Coördinator meer focus heeft op z’n daadwerkelijke taak

10. EXPERIMENT
1. Onderzoek naar veel voorkomende datachecks
2. Plug-in in BIMserver
3. Drie projecten getest
4. Publicatie geschreven
5. Officiële presentatie in september

12. COMMON REQUIREMENTS
There should be only one IfcProject object per file (no more, no less);
There should be only one IfcSite object per file;
All objects should be linked to an IfcBuildingStorey object;
There should be at least one IfcBuilding object in the dataset;
There should be at least one IfcBuildingStorey in the dataset;
The naming of the building storeys should be consistent and in order, i.e. floor-numbers;
The length unit should be millimeters; The area unit in m2; The volume unit m3;
The objects should be ‘close’ to the origin point (0,0,0) of the dataset;
Objects found across multiple ‘aspect/reference models’ should have the same position and
orientation point;
There should be no intersections in the individual ‘aspect models’;
There should be no duplicate objects in the entire dataset.

13. AANVULLENDE EISEN
Typische “EXTRA” eisen vanuit een opdrachtgever / beheerder / eigenaar:
The dataset should have the true North set;
The site elevation should be set;
The site latitude and longitude coordinates should be set;
The site cadaster ID should be available.

19. CRUCIALE PUNT
Voorheen:
Per e-mail/dropbox/sharepoint/whatever data opsturen
Nu:
Uploaden naar website en niet geaccepteerd worden als data interne fouten
bevat.

20. CRUCIALE PUNT

Gedachtegang is dat het ‘over de schutting gooien’ gedrag wordt belemmerd
en de verantwoordelijkheid van goede datasets bij de bron komt/blijft.
(zodat de coördinator niet met het de gebakken peren zit)

27. CONCLUSIE & DISCUSSIE
Best goede data
Niet alles eenduidig te toetsen (benaming van verdiepingen)
Nog steeds geen inzicht in potentie
“Whereas this study has shown the potential of online automated compliance checking, there is
no clear evidence that the quality of models will improve in the process. Further research would
be required across multiple projects to validate this hypothesis.“
Misschien komt er wel geen data meer van een toeleverancier omdat de
drempel te hoog is; dan levert dat juist extra problemen op.

28. OPEN UITNODIGING
Zouden graag verder willen onderzoeken in een ‘live’ project
Kijken naar gedrag van toeleveranciers
Wellicht ook eenvoudige automatische coordinatie tussen toeleveranciers
Misschien zelfs online BCF dashboard koppelen voor issue management
Interesse? Leon.vanBerlo@tno.nl of 06-42367465

29. DE TNO ‘STAP TE VER’
Data automatisch corrigeren
Meters naar milimeters
Lat/lon overnemen van hoofdmodel
Nulpunt corrigeren
Etc…
Beter vastleggen van eisen met methode die voor computer eenduidig is
(query taal; ruleset; Model View Definitions, concept bibliotheken, enz…)

30. FAQ
Ja, de broncode van de plug-in is gratis te downloaden:
github.com/opensourcebim (en komt standaard in de 2.0 versie van BIMserver)
Nee, formeel mag ik de paper niet e-mailen
Nee, deze 3 cases zeggen niks over de hele sector en zijn niet te generaliseren
Ja, ik denk dat er ook potentie zit om dit concept toe te passen op andere
plaatsen in het proces (dus niet alleen tussen aannemers en toeleveranciers)
