International Journal of BIM and Engineering Science IJBES 2571-1075 10.54216/IJBES https://www.americaspg.com/journals/show/1545 2021 2021 Building Information Modeling Management Master Student, Syrian Virtual University Aya Amino Lecturer Professor at the Faculty of Engineering, Al-Rasheed University, Damascus, Syria Sonia Ahmad In the last decade, the projects of the Architectural, Engineering, and Construction Industry (AEC) in Syria faced endless difficulties and problems, in addition to the intense competition between the construction sector companies. This prompted many companies to want to adopt best practices to reach their goals, therefore any work organization should have a clear vision of what it wants to achieve, for what purpose, and how? Building Information Modeling (BIM) around the world has proven its ability to solve all the problems facing engineering projects. Unfortunately, AEC companies despite all that great value did not use BIM. For many reasons, mainly: there is no comprehensive descriptive approach that explains how to apply it and a mechanism that shows how to measure and develop it within companies, in addition to their fear of adopting modern technologies that push them to need new engineering competencies because of not realizing its importance. The purpose of this research is to propose a methodology to measure and develop BIM maturity in Syria in general. In addition, to assess the level of maturity of our institutional BIM through the BIMM maturity matrix in particular. This is done by applying the most important models for measuring maturity around the world on a number of Syrian AEC companies in the private and public sectors. Analyzing the performance of BIM in it, comparing the results, and assessing the level of institutional maturity. Then conducting analyses and comparisons based on these conclusions and making additional recommendations and proposals to develop the matrix in accordance with practical reality in order to reach the optimal and integrated level for construction projects 2022 2022 73 89 10.54216/IJBES.050105 https://www.americaspg.com/articleinfo/22/show/1545
