Abstract: With the continuous acceleration of my country's economic construction, engineering supervision has an important impact on the improvement of construction quality. Modern construction supervision is faced with a complex environment and involves many scopes and contents. Therefore, supervision staff need to look at multiple aspects and angles. Set out, conduct an in-depth analysis of the construction project. Based on this, the author of this article conducts in-depth analysis and research on the problems of engineering supervision according to the actual situation of the construction project, and proposes a targeted quality control method to improve the quality and construction safety of the construction project under the principle of engineering supervision.
