Always the same problems?

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

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

Construction design process mining
“Process mining analytics did us realize that we use our IT systems to store information, but those systems don’tautomatically facilitate an efficient process”
-Process engineer, contractor

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

BIM based Process Mining
![Page 32: Process mining in the construction industry beyond bim congres](https://reader030.vdocuments.mx/reader030/viewer/2022020314/58aabf0b1a28ab16338b673f/html5/thumbnails/32.jpg)
Conclusion and discussion
1. Current IT systems can be used for processmining, valuable data in there!
2. Process mining enables fact based problemidentification
3. BIM based process mining is possible
-Use GUIDs to connect information from different tools.

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