The challenge of improving the efficiency of the different phases of a building or infrastructure life demands considerations of innovative technologies such as Augmented Reality (AR) and Virtual Reality (VR). During this last decade, AR/VR systems for construction started to be emerged. These applications aim to virtualize or augment in real time the content of the Building Information Modeling (BIM) in order to support continuous improvement. To ensure the maturity of these applications, implementing a maturity model is needed. Based on literature, several maturity models for BIM have been proposed. However, it stays generic and needs to be adapted to the AR and VR technologies in the BIM context. To that end, we started in this paper by proposing an adapted AR/VR maturity model for BIM that aims to evaluate the maturity of these technologies according to the BIM lifecycle. This model has been conceived based on a mapping between three existing maturity models corresponding to AR, VR and BIM technologies from the most adapted existing works that deal with our goal. As a result of this mapping, three maturity levels have been identified and a detailed description of each level has been established. This model will be proposed to construction companies in order to evaluate their maturities on the use of AR/VR technologies.
