Building information modelling (BIM) has recently become a key to bolster the performance of construction projects. BIM is a virtual platform that all data about all phases of the project, such as maintenance, management, and operation are entered and stored. BIM is preferred for reasons such as data storage, coordinated work among partners, cost estimation, reduced time losses due to rework, and virtual reality. Despite all these benefits, Turkish construction companies have not implemented BIM at the desired level. Many studies pinpointed that the low level of awareness of construction practitioners about BIM and its concepts is one of the main reasons. Thus, this study aimed to identify the awareness of construction practitioners. 25 terms were extracted from the literature. Then, a questionnaire survey was conducted with the participation of 41 experts. The experts expressed their knowledge level about these terms based on the 5-points Likert scale. The survey data were analysed using frequency analysis and descriptive methods. Results revealed that except the traditional method which includes 2D,3D, and CAD programs, awareness levels of other terms are extremely low. Even if the construction companies implement BIM in construction projects, they cannot fully utilize all benefits of BIM. The practitioners just know the basic term of BIM and they have very low awareness about complex terms of BIM. The reason for this may be that there is no guiding regulation or standard that can be used throughout the country. Additionally, the use of BIM is not mandatory in public projects in Turkey so that this could be also another factor that hinders the BIM implementation.
