# 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"

1. `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

2. `COMMON ASSEMBLIES`/`GROUNDING`/`(3) ... x 10' CU CLAD GRD ROD & 4"X12" GND BAR`
    * **Count:** 1

## Riser

1. * `Area` = "Typical - Building All Electrical Riser Rooms"

    `COMMON ASSEMBLIES`/`GROUNDING`/`GND = \#3/0 & 1" CONDUIT - EMT`
    * **Length:** 15
    * **Count:** 1

## Telecom Ground Bridge

1. * `Area` = "01 - Feeders/Risers Building"

    `COMMON ASSEMBLIES`/`GROUNDING`/`TELE/DATA GND BRIDGE, ..., W/ COVER & (60') #6 THHN GREEN`
    * **Count:** Only as shown

## Pool Bonding

1. * `Area` = _Contentious_

    `COMMON ASSEMBLIES`/`GROUNDING`/`GND = \#3/0 ...
    * **Length:** Perimeter of the pool plus length to nearest riser.
    * **Count:** 1?
