The responsible party of secondary electromechanical design is mainly the electromechanical designer, who is responsible for deepening and optimizing the primary electromechanical design according to the requirements of fine decoration design to ensure the coordination and smooth construction of electromechanical system and decoration design. In the secondary electromechanical design, designers need to coordinate with various design units, put forward work requirements related to the electromechanical system, and check and modify the primary electromechanical system, equipment and computer room according to the fine decoration design.
