ABSTRACT
Owners are starting to enforce that architects and
other design professionals, construction manag-
ers and construction companies adopt BIM. This
trend gained enormous momentum when the
General Services Administration (GSA) of USA
announced that it would require all schematic
design submittals to be in BIM format starting in
2006 (US-GSA, 2008). Many other similar uptakes
from Europe and Australasia have followed
(Mihindu and Arayici, 2008).
