# Unit Takeoff

## Info

"Units" includes [[#hotel]] and [[#residential]] spaces.

> [!info] Americans with Disabilities Act (ADA) Terms
> * hearing impaired (HI or H.I.)
> * hearing impaired communication (HC or H.C.)
> * mobility features (MF or M.F.)
> * accessible (Acc.)
>   * usually refers to mobility features.

### Hotel

> [!info] Also Known As
> * Guestrooms
> * Keys

> [!trivia]
> The term "key" as a synonym of "hotel room" is a synecdoche,
> referring to the unit's door key.
> In the pre-digital days of hotel management,
> one could count the rooms of a hotel
> by the keys behind the front desk.

### Residential

> [!info] Also Known As
> * Condos - resident-owned
> * Apartments - resident-rented

## Sequence

### 1. Estimate preparation

1. Locate Unit panels and relevant keynotes
    * bus amps

2. Read about the project specifications and construction type
  * partition framing (wood or metal studs)
  * stud depth
  * wiring methods (NM or MC)
  * wiring device plates (decora or standard)
  * wiring device specs (are 15A devices allowed or minimum N5-20R)
  * equipment (20A Kitchen and bath)

1. Fill out OneNote

### 2. 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.

1. Kitchen and Bath
2. General assemblies
3. Low Voltage
4. Lighting Fixtures
5. 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.
