# Grounding Takeoff
|
|
|
|
This script is intended to cover both electrical and telecom grounding
|
|
in lieu of detail sufficient for standard takeoff (e.g. a grounding riser).
|
|
|
|
Note that the material provided in this system is intended to be budgetary,
|
|
not especially consistent with the actual install.
|
|
|
|
### System Grounding
|
|
|
|
> `Area` = "01 - Feeders/Risers Building"
|
|
|
|
`COMMON ASSEMBLIES`/`GROUNDING`/`GND = #3/0 & 1" CONDUIT - EMT`
|
|
|
|
* Length: Perimeter of the main electrical rooms plus length to each riser.
|
|
* Count: Total number of electrical rooms
|
|
|
