Curriculum Vitae

Bill East is a serial innovator who has created global standards and systems that stand the test of time. Here are three examples of Bill’s work:

  • The "Standard Data Exchange Format" has been delivering cost-loaded Critical Path Method schedules to help U.S. Army, Corps of Engineers contractors get paid on time for 25 years.
  • The cloud-based ProjNet service (including the "Doctor Checks" application) has been improving world-wide public design quality for over 15 years. Today, there are over 100,000 “Doctor Checks” users.
  • Starting in 2006, Bill and his team produced the majority of technical standards found in the United States National Building Information Modeling Standard (NBIMS-US V3). One of these, the Construction Operations Building information exchange (or “COBie”), can be found in contracts around the world.

Bill's most recent publication is a review of the first decade of the US National BIM Standard. His recent books include "The Critical Path Method Tutor" and "Delivering COBie in ArchiCAD." Two new books, "COBie Quality Control" and “Delivering COBie in Revit” are slated for 2017.

Today, Bill is owner of Prairie Sky Consulting where he and his team deliver practical solutions for Better Information Management. Bill is also co-Director of the COBie Academy, the authoritative source for quality COBie and BIM education and mastery.

Bill has a B.S. in Civil Engineering from Virginia Tech and M.S. and Ph.D’s from the University of Illinois in Urbana-Champaign. He is a Registered Professional Engineer and Fellow of the American Society of Civil Engineers.
