  • Master thesis researchPresentation @Beyond BIM symposium, 09-12-2015

    Stijn van Schaijk

    Process mining in the construction industry

  • About myself

    Study: Master, Construction Management andEngineering @ TU/e

    Sept 2015 - now: BIM consultant @ Bureau Based

    Job 2012 sept 2015: BIM employee @ Hendriks Bouw en Ontwikkeling

  • 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

  • IT in construction to manage processes

    Process mining with facility management data

    Construction design process mining

    BIM based process mining

  • 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 dontautomatically facilitate an efficient process

  • Process mining with facility management data

    Errors solved within 3 minutes costed 300 euros each (totalof 723600)

  • Process mining with facility management data

    We can better invest in data analytics to save money thanfire our own people

  • Case study: BIM based process mining Target: Shorten construction projects

    How: Plan, (Autonomous-) Capture, Analyse and Re-use process data from construction sites

    With: Using BIM and Process mining techniques

  • Case Study: Plan

    1. Connect planning to IFC

    2. Generate As-Planned models

    Re-use

  • 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

  • Data explosion

    More devices,

    More sensors,

    More cameras.

    Upcoming: Intelligent ways to register processes

    So: more data

  • BIM based Process Mining

  • BIM based Process Mining

  • BIM based Process Mining

  • 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
