The modern construction industry is known as complex due to magnitude of the projects on one hand, and the diversity of the works included in the project, on the other hand. The establishment of projects is no longer limited to the implementation of a few types of work or activities in the project. However, it is increasing in response to the overall technical and urban development of life, and to the increasing requirements of the beneficiaries of these projects. Projects nowadays are integrated and complex systems of different works and contracts, which are connected with each other to perform the overall function of the project, which, in return, has evolved as well as its qualitative content. This research aims to improve the quality of design, and contracting phase of the State Company for Engineering Studies in Damascus’s projects, by examining the current reality of practices and methods in quality management during the designing stages and pointing out its weaknesses. Determining the factors affecting the quality of the contractual phase of the company, through a survey published online. Twenty-two engineers working in the company have responded. It was estimated that the company's realities and the extent to which the employees understood the importance of quality. Through this research, a system of procedures was proposed to ensure the quality of design and contractual phases with ISO 9001: 2015 Integrate it with building information modelling technology that addresses or overcomes current problems. Using BIM provides an effective means to increase the overall quality of the company's projects. 2023 55 73 1910 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJBES.060204 https://www.americaspg.com/journal/22/article/1910 https://www.americaspg.com/storage/51775083325.pdf
