Abstract: This article introduces the latest progress of BIM in the United States, which is the forthcoming publication of the National BIM Standard-United States (NBIMS-US) Version 3. The expanded NBIMS-US contents for Version 3 include information exchanges, reference standards, standard practice submissions, and terminology/glossary submissions. New for Version 3, an introductory narrative and wayfinding section is added to make the standard more accessible and readable. In the end, the authors look into the future of the facility industry and NBIMS-US, believing that NBIMS-US will become a means to lead the A/E/C/O/O industry as it moves forward to adopt BIM technologies and processes.
