How To Mark Up Electrical Drawings

How To Mark Up Electrical Drawings

Whether you are marking up plans online or even by hand, you don’t have to be an expert to learn how to mark up successfully. It is important that you never try to rush the process. Being organised and creating thoughtful and useful drawings will save you much time and money in the long run.

01

DO NOT use BLACK to Mark Up, as it is very hard to read.

02

DO NOT put too much information on one drawing, use multiple, if required.

03

DO NOT write upside down on drawings or plans.

What are Electrical Drawings?

Electrical drawings act as a guide to all things power and lighting related to a building project. They are used to accurately provide guidance to the contractors who are installing or updating electrical systems. Electrical drawings use specific lines and symbols, and often accompany wiring diagrams.

What to Use to Mark Up Plans?

Thanks to technology, you can now mark up electrical drawings with your iPad or laptop with the simple click of a button using programs such as PlanGrid, PDF Annotator and Drawboard PDF.

Can I use photographs to show specific details?

Yes, you can. Photographs provide a real-life record and enable a clearer understanding of measurements or specific details. We will accept photographs, sketches, original drawings and handwritten text to collate and combine.

Can I Mark Up hard copies?

Yes, start with a draft pencil mark up, this will ensure all notations fit the page and can be easily read, and all plans should be scanned in colour at 300 dpi at the native page size.
