Unit Takeoff |
Unit Takeoff
Important
Complete pre-takeoff-research, including wiring-method-selection and wiring-device-research, before beginning takeoff.
[!info] See multi-family-dwellings.
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.
- Kitchen and Bath
- General assemblies
- 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.
