Abstract
With the continuous advancement of China's urbanization process, the demand for construction projects is increasing, which is both an opportunity and a challenge for construction companies. If the enterprises themselves can grasp the background and policy conditions to maintain a high level of construction engineering, then its enterprise benefits and future development prospects will be excellent. However, there are also many companies whose own reputation and actual benefits have been affected for poor engineering quality caused by poor construction management. This is exactly what we must pay attention to. This article will analyse and explore the relevant work to improve the engineering quality of different phases of engineering construction and to guide the management of the construction unit in the future from the perspective of the construction unit to strengthen the project quality supervision.
