[!info] Scope

• Telephone
• Data
• Cable TV

Important

Not to be confused with low-voltage-takeoff.

Note: Empty Conduit

Where COMMON ASSEMBLIES/PDI EMPTY & DUCTBANK CONDUIT/... is specified, FEEDER CONDUIT AND WIRE/... is also acceptable.

"Site Low Voltage Duct Bank"

1. • Area = "2 - Site"
   • Phase = "Site"
   • System = "LVD - Site Low Voltage Ductbank"
   • Bid Item = "1 - Site"

   COMMON ASSEMBLIES/PDI EMPTY & DUCTBANK CONDUIT/...

   • Size and quantity per proposal > drawings > assume (4) 4"C
   • Length = Length measured from MDF to 5ft beyond building footprint

Garden Style: Outside of every building

[!important] Long-Radius Elbows Note requirements for long-radius elbows, substitute items as necessary.
