As-builts
What goes on an electrical as-built, how to mark it as you go, and what to hand over at closeout.
Electrical
What an electrician needs from a PDF markup app, from symbols and counts to an editable export.
Count
Count by clicking, or box one symbol and let Find & Count mark the rest. Then check the total.
Measure
Set the scale, measure lengths and runs in feet and inches, and work out square feet.
Switching
Why crews switch, who it suits, and how to start without changing how the office works.
