Abstract: The study on the engineering quality problems and countermeasures of State Grid's small-scale infrastructure projects explores and analyzes the current situation and existing problems of the engineering quality of State Grid's small-scale infrastructure projects, and proposes a series of countermeasures. The study believes that the main factors affecting engineering quality include the uneven quality management level, inadequate quality supervision, and low design and construction technology level. To improve engineering quality, countermeasures are put forward in aspects such as strengthening quality management, enhancing design and construction technology, ensuring material and equipment quality, and strengthening acceptance and after-sales service. Meanwhile, it emphasizes the cultivation of a good quality culture and improves the quality awareness and professionalism of employees.
