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

This scope is included here for its similarity in content. It may be more appropriate in electrical-takeoff

[!quote] joel-jansen 2026-01-20T16:30 (pp.) josh-ford prefers it in electrical, but I'm not concerned. So long as it's named "Pool Bonding" it's fine.

1. • Area = Contentious

   COMMON ASSEMBLIES/GROUNDING/`GND = #3/0 ...

   • Length: Perimeter of the pool plus length to nearest riser.
   • Count: 1?
