Abstract: BIM technology has been rapidly developed over the past 10 years. However, it’s still
difficult to deliver information smoothly between different phases due to that there are many
participants involved in a building project. Consequently, a completed BIM still can’t be constructed.
To address this problem, this paper proposes a phased and progressive modeling method (PPMM) of
BIM, together with a basic agreement for cooperative modeling among all participants, and modeling
procedures. The method supports various participants to cooperatively create BIM under a unified
framework. Being verified by a real project, the PPMM is effective for preventing from repetitive
modelling and inconsistent data, and is helpful for generating a completed and consistent BIM in BIM
database, which is a foundation of building lifecycle-oriented BIM application.
