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
2. accubid-setup#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.
