Drawing confirmation plays an indispensable role in various projects, especially those involving lighting. On the one hand, it is the key to ensure accuracy. The various parameters of the lamps in the lighting design drawings are accurately presented. After confirmation, it can avoid the actual lighting effect from being contrary to expectations. On the other hand, it acts as a communication bridge, through which designers, construction parties, customers and suppliers convey their needs and work together. Furthermore, it is a “ruler” for quality control. The supervisor checks according to the drawings to ensure construction compliance. At the same time, it can effectively prevent cost out-of-control and construction delays, and can also verify whether it complies with regulatory safety standards, laying a solid foundation for the smooth progress of the project.
