Congratulations to CBIM ESR Zijian Wang, who received the Charles M. Eastman Top PhD Paper Award at the joint CIB W78 – LDAC 2021 conference in Luxembourg!

Congratulations to CBIM ESR Zijian Wang, who received the Charles M. Eastman Top PhD Paper Award at the joint CIB W78 – LDAC 2021 conference in Luxembourg ( This award, presented at each of CIB W78’s annual international conferences, recognizes the importance of developing top young researchers in the field “the application of integrated IT throughout the life-cycle of the design, construction and occupancy of buildings and related facilities”. The award is named after a seminal researcher in this field, Chuck Eastman, who has, over his illustrious career, supervised and mentored many of the top researchers found across the world.


Zijian’s research titled “Room Type Classification for Semantic Enrichment of Building Information Modeling Using Graph Neural Networks” represents BIM models as graphs and applies Graph Neural Networks (GNN) to BIM graphs for semantic enrichment. A GNN model was trained for room type classification of residential apartments and was compared against other machine learning algorithms. It pioneers the use of GNN in BIM and opens the door to other possible applications.


Zijian Wang is supervised by Rafael Sacks at the Technion – Israel Institute of Technology and is working on graph representation of BIM models for semantic enrichment and interoperability.Download the full article here:

The Eastman Symposium to honor Professor Chuck Eastman will be held on Thursday, May 13 2021 – Link for registration is available!

Colleagues from around the world have organized the symposium to honor Professor Chuck Eastman and celebrate his life and legacy.  The Eastman Symposium will be held on Thursday, May 13, 2021, starting at 13:00 GMT (8:00 a.m. US EST) and will run uninterrupted for 24 hours. In keeping with the global impact of Professor Eastman’s work, the individual sessions will be chaired by experts from around the world.

The symposium will be anchored by two real-time networking sessions, where Chuck’s friends and family will gather.  The symposium will include two keynote lectures from Eastman’s closest colleagues and 14 academic paper sessions focused on research topics initiated and championed by Chuck over his 55-year research career.

The 14 academic sessions represent the arc of Professor Eastman’s career, from his early work in design cognition, through work in computer graphics, solid modeling, building product models, rule checking and BIM. The chairs are leaders in these fields, selected from experts and colleagues of Chuck’s from around the world.
