2, building lighting design needs to understand the project overview and the progress of the project, whether it is a new building or an old building. If it is a new building, what is the progress of the project? Is it just out of the ground, or has it been roofed, or is it all completed? Before capping, it is best when preparing the facade. At this time, lighting design and lighting construction plan must be made as soon as possible, because if it is later, assuming that the facade needs to be equipped with lamps, it will increase the difficulty of construction, or the facade The surface wiring is very ugly, and it can't even be realized by construction. Of course, the sooner the building lighting project is planned, the better, because there is enough time for design and communication, but because the tracking time is long, the owner is not in a hurry to determine the lighting plan because it is still early, which increases the difficulty of project tracking . Of course, after the roof is capped or even in old buildings, building lighting projects can be done, but the difficulty of construction has increased a bit, and some pipelines cannot be hidden and cannot be used for concealed works. I can only find ways to conceal as much as possible, and of course some lighting The company is more willing to build a completed building or an old building, because the construction period is short and there is no need to follow the construction schedule. If it is a very high-rise building, the construction period may be quite long, which increases the construction cost.
