In actual construction, the specific decoration scheme is declared by the construction team, and the construction is carried out after being approved by the supervisor and the construction unit. Among them, building 1 was pasted with cement mortar according to the original design practice, and building 2 was constructed by back hanging dry hanging method.

At the beginning of 20 1 1, some tiles on the wall of building 1 fell off, especially in the lobby, and some tiles in the front room of the shared floor fell off, but no tiles were found in building 2.
