Although various BIM capability and maturity models have been developed to meet different BIM capability/maturity assessment purposes, there has not been a model which is broadly used and commonly accepeted in the literature. A Reference Model for BIM Capability Assessment (BIM-CAREM) was developed based on the meta-model of ISO/IEC 33000 to be used for assessing BIM capability levels of AEC/FM processes. This paper aims to compare the components of BIM-CAREM with the assessment questions of the identified models from the literature. Moreover, data collected from a previously performed case study was used to carry out self-assessments by using these models. Then, these assessment results were compared with the findings gathered from assessments performed with BIM-CAREM. The comparison indicated that, BIM-CAREM has more detailed and specified questions for assessing BIM capability of different AEC/FM processes and has comparable assessment results to that of identified capability models.
