PE CAD Drawings
Understand that a PE is exactly that a Professional Engineer so you will get what you pay for.
When you pay an engineer for CAD drawings of your building and a professional fire alarm design or camera design you can then put the project out to bid because the drawings will be to scale and the specifications will list exactly what you are looking for.
