156 Chapter 6
Engineer’s drawings are required for all commercial projects involving electrical work, including ad-
ditions, renovations, and new construction. A permit is required prior to commencing any on-site work.
Drawings and permits are also needed for residential projects when substantial electrical work is to take
place. For small projects, a licensed electrician can provide the information required to obtain an elec-
trical permit.
Concept and designs are the first stage of any project. When established, the next stage is construc-
tion drawings. Once the floor and reflected ceiling plans are complete, they are passed to the engineer to
produce the electrical drawings. The engineer’s drawings become part of the construction-drawing set.
