# Unit Takeoff

> [!info]
> See [[multi-family-dwellings]].

[[pdi-building-types]]

## Prerequisites

> [!important]
> Complete [[pre-takeoff-research]],
> including [[wiring-method-selection]] and [[wiring-device-research]],
> before beginning takeoff.

1. [[pdi-conest-project-setup#Create Unit Matrix|Create Unit Matrix]]
2. [[accubid-setup#Create Unit Typicals|Create Unit Typicals]]

## 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.

3. Kitchen and Bath
4. General assemblies
5. Low Voltage
6. Lighting Fixtures
7. 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.
