1. Master thesis research
Presentation @Beyond BIM symposium, 09-12-2015
Stijn van Schaijk
Process mining in the construction industry

2. About myself
• Study: Master, Construction Management and
Engineering @ TU/e
• Sept 2015 - now: BIM consultant @ Bureau Based
• Job 2012 – sept 2015: BIM employee @ Hendriks Bouw
en Ontwikkeling

3. Always the same problems?

4. Complexity in construction
• Winch (1987): construction projects are amongst the most complex of all activities.
• Gidado (1996): rapid increase in the complexity of construction processes

5. IT in construction to manage processes

6. Process Mining
• Analyse Event Logs to learn from processes

BIM based process mining

8. Construction design process mining
Most extreme result: validating 1 specification had 1904
process steps!

9. Construction design process mining
“Process mining analytics did us realize that we use our IT
systems to store information, but those systems don’t
automatically facilitate an efficient process”
-Process engineer, contractor

10. Process mining with facility management
data
Errors solved within 3 minutes costed 300 euros each (total
of €723600)

11. Process mining with facility management
data
“We can better invest in data analytics to save money than
fire our own people”
-Facility manager, Erasmus Hospital

14. Case Study: Plan
1. Connect planning to IFC
2. Generate As-Planned models

Re-use

15. Case Study: Capture
1. Scan construction site with drones
2. Create As-Built Point cloud model
(Structure from motion)
3. Compare As-Built with As-Planned
4. Merge results with event log

28. ‘Data explosion’
• More devices,
• More sensors,
• More camera’s.
• Upcoming: Intelligent ways to register processes
• So: more data

29. BIM based Process Mining

30. BIM based Process Mining

31. BIM based Process Mining

32. Conclusion and discussion
1. Current IT systems can be used for process
mining, valuable data in there!
2. Process mining enables fact based problem
identification
3. BIM based process mining is possible
-Use GUIDs to connect information from different tools.

33. Further work
1. Automate process capturing on construction
sites.
2. Combine data from several IT systems.
3. Better/more advanced planning consult
