Professor Charles "Chuck" has passed away.

Chuck Eastman is certainly the most influential, visionary and important scholar, pioneer and practitioner in the field of digital methods in the built environment. He is the very inventor of what we refer to as Building Information Modelling today. Computer Aided (Architectural) Design, Parametric Modelling, Interoperability, Computer Supported Collaborative Work in AEC/FM would look very different without his ground braking contributions.

His game-changing ideas and concepts will be passed on through his seminal body of work documented in scientific literature and practical BIM handbooks. All those who have had the opportunity to have a conversation with him, be taught or guided by him or to work with him praise him for his incredible passion, interest and attention, his thorough and deep reasoning and the abundance of knowledge and insight he so happily shared with undergraduates, graduates, PhDs students, colleagues and practitioners.

We have lost a truly great thinker, scholar and teacher. Condolences to his family.

Ghang Lee (one of his many former PhDs and co-author of the handbooks) has posted a very concise and kind obiturary on FB.
