Expert Answer

Include all of the lighting locations, switch locations, and switch varieties, along with how all the lights are connected—that way, you'll know exactly what switches on and off and where those switches are located. It also helps to include the furniture, arrangements, and cabinets, so you know what the lighting is placed relative to in the final layout.

Question

Is a reflected ceiling plan the same thing as an electrical lighting layout on engineering construction drawings when there is an electrical lighting layout plan included?

Community Answer

No. The reflected ceiling plan focuses on the everything on the ceiling. The electrical layout plan is a part of the RCP. The electrical construction drawings must be referred to in order to determine the electrical wiring of the ceiling lights and sprinklers.
