Any decoration project is inseparable from the decoration construction team and the quality inspector (project manager), and even the largest decoration company is composed of such small cells. The quality of the project depends on them. It can be said that finding a good decoration team will ensure the quality; With a good project manager, the decoration owner can feel at ease. In the process of decoration construction, the project manager is the protagonist, who determines the quality of a decoration project, the rational use of decoration materials and the progress of construction. In short, he is the overall arrangement and coordinator of the whole home improvement project. A project manager who is considerate of customers will consider the actual interests of the owners everywhere, especially in the process of decoration, and he can guide the builders how to save materials and how to deal with various construction problems correctly and reasonably. A responsible project manager will arrange the schedule reasonably, inspect the project at the construction site regularly, strictly manage the construction team, strictly control the quality, and avoid quality problems to the greatest extent. Once the construction problems are found, the relevant personnel will be urged to solve them as soon as possible to ensure the construction progress. The project manager participates in all acceptance links, including material acceptance, concealed engineering acceptance such as water and electricity, and completion acceptance. Some project managers can carefully check the grounding and positive and negative phases of each power socket to ensure the safety of the circuit; Irresponsible project managers may not go to the construction site for a week or two, and the quality problems during this period are likely to become hidden dangers for the owners in the future.
