Since education is a basic right for every child, there is an urgent need for school rehabilitation projects, especially after the massive destruction caused by the war in Syria in the past decade. BIM technology has been used in the past years because it is an integrated and effective process for planning, studying, and implementing projects. However, BIM has not been properly used in the study of post-war rehabilitation projects, especially in developing countries. This research discusses the effectiveness of applying BIM in the rehabilitation projects of public facilities in Syria after the war by increasing the accuracy of quantities estimation for these projects. The main results indicate that the application of BIM in the Al-Ejref school rehabilitation project in the Al Qunaitra governorate represents great potential in increasing the accuracy of quantity estimation, as the traditional methods are limited and have a large margin of error. 2022 08 18 1546 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJBES.050201 https://www.americaspg.com/journal/22/article/1546 https://www.americaspg.com/storage/81775147805.pdf
