Unit Takeoff
[!info] See multi-family-dwellings.
Prerequisites
Important
Complete pre-takeoff-research, including wiring-method-selection and wiring-device-research, before beginning takeoff.
Takeoff
[!tip] Preparing for Unit Takeoff Units generally have very little variation. It is usually best to copy-paste takeoffs rather than re-build them for each unit.
- Load Center
- General assemblies
- Water Heater
- HVAC
- Laundry
- Kitchen
- Bathroom
- Low Voltage
- Lighting Fixtures
- Lighting Control
Tip
It may be more efficient and neat to not copy switches, instead keeping the switch assembly list open and creating them new for each unit, since the types required can vary greatly between units.
Tip
Consider using a "Typical - All Units" for scope identical between all unit types.
- WAP Outlets
- MSDE's
